Gai Ikari

"Goooooookaiiiii......Silver!" "Let's do this ecstatically!" "Gokai Silver, Gold Mode!"

The sixth member of Gokaigers, Gai Ikari (伊狩 鎧) is Gokai Silver of the Gokaigers. He is the only Earthling on the team and primarily utilizes the powers of the 6th Sentai Warriors of the past.

Becoming Gokai Silver
Gai is an Earthling teenager and a self-professed Super Sentai fanboy. He was granted the Gokai Cellular by the spirits of the three dead 6th Rangers DragonRanger, TimeFire, and AbareKiller, all of whom possessed dinosaur themed mecha and were initially antagonistic to their respective teams. This happened after he risked his life to save a young girl from a car accident.

After he was given his powers Gai recognized how similar his ranger form was to the Gokaigers and went searching for them, hoping to join their team. During this time he attempted to unlock the greater powers of the Abarangers, Zyurangers and Timerangers. However, short of transforming himself into Gokai Silver, he couldn't unlock the greater powers.

In the aftermath of the Gokaigers' team up with the Goseigers and battle with the Black Cross King, Gai as Gokai Silver watched the Gokai Galleon and gave his respect.

Meeting the Gokaigers
Upon meeting the Gokaigers, he attempts to impress them and eventually succeeds by transforming and defeating the latest action commander. Gai is later taken back to the Gokai Galleon and is questioned about his origin and the great powers in his possession. Gai then reveals that he has been unable to get the great powers to reveal themselves and that he would need the DragonRanger, TimeFire, and AbareKiller ranger keys to make them work. Marvelous then confiscates his Gokai Cellular and Gokai Silver Ranger Key until he can prove that he has something that Marvelous doesn't. He later impresses Marvelous by going into battle without his Gokai Silver powers. Unlike the Gokaigers, Gai isn't out to find the great powers; he is out to save mankind and destroy the Zangyack, something Capt. Marvelous finds to be an interesting new concept. Marvelous accepts him and the Gokaigers accept him, however, as a pirate apprentice.

Gokai Silver Gold Mode
Later, Navi later links him to the Gokaigers' keyroad which allows him access to the treasure chest of Ranger Keys. He tests this out by summoning Dairanger's KibaRanger key and succeeds. Eventually, he tries to impress everyone, to which only annoyed Doc as he felt like he was nothing compared to him. Eventually, during a battle with the Zangyack, Gai somehow combines both the Go-on Wings Ranger Keys and becomes half Gold and half Silver. Despite this though, Worian "de-bones" the Gokaigers with the exception of Doc and Gai. As Gai tries to convince Doc to help him, he turns him down telling him that he feels pathetic while he's around him. Eventually, Gai finds Worian and does battle with him only to be on the losing end until Doc arrives, encouraging Gai to use the power of all the past 6th Hero Rangers keys at once. He believed it to be impossible, but with encouragement from Doc, he manages to create the Gold Anchor Key and becomes Gokai Silver Gold Mode. With his newfound power, he defeats Worian, and eventually with the restored Gokaigers, defeats him a second time. After that, he received a 100,000 bounty on his head.

Gingaman
Sometime later, he learns that Navi helps the Gokaigers search out the Greater Powers of the Super Sentai. Navi's latest clue was to find the lost forest. While the others were stumped, Gai quickly figures out that Navi's clue is referring to the Seijuu Sentai Gingaman. He proceeds to tell his crewmates about how they faced off against a group of Space Pirates to which Doc is nervous about. Eventually, they find the Ginga Forest and an injured Hyuuga. Gai learns of his attacker's identity, Basco, and also learns of his history with the Gokaigers. Gai then points out Hyuuga and how he helped the Gingaman defend the Earth as Black Knight. He asks him to sign his Seiiju Sentai Gingaman Comic Book before being told to get him somewhere safe and away from the battle that would ensue between the Gokaigers and Basco's Wolzard Fire, MagiMother, and DekaMaster Puppet Rangers. He manages to get Hyuuga to safety to have his wounds treated, all the while telling him that it was his dream to be apart of a Super Sentai and save people despite that he doesn't know what it means to be one. Hyuuga then asks him to hand over his Gokai Cellular so that he could battle as Gokai Silver. He believes that Hyuuga would do a better job defending the Earth and was about to give him his Cellular before Basco showed up to forcibly take the Greater Power of the Gingaman for himself. However, Marvelous interrupted this and did battle with Basco's Black Knight Puppet Ranger. He finds himself at odds with himself as he believes Hyuuga would do a better job, but with a bit of unintentional advice from Marvelous, Gai tells Hyuuga that he will be Gokai Silver and defend the Earth for him and everyone. Hyuuga tells him that he was testing Gai's resolve and was proud that Gai found his resolve to be Gokai Silver. Gai proceeds to battle along his team and defeats the puppet Black Knight as Gokai Silver Gold Mode. Hyuuga gives Gai the Black Knight Ranger Key and entrusts the Greater Power of the Gingaman to him, saying that he would rather have all the power of the Super Sentai in one place and that Gai should defend the Earth. Gai promises to do so as he and his crew fly off in the Gokai Galleon.

Shooting Stars
Gai showed his finalized Super Sentai encyclopedia for his crewmates to research how the previous Sentai teams fought. Joe, who showed no interest, left the Gokai Galleon to pick up food - with Gai following him to learn more about him. During their walk, they bumped into a young boy who nearly hit Gai with his bicycle. The boy, Shota, arrived at a nearby shrine to wish for fair weather- only to see Action Commander Stargull holding a black stone. Spotted, Shota pedaled away from the Zangyack and his Gormin, running into Joe and Gai who assumed their Gokaiger forms quickly dispatched the Gormin. Despite Gokai Blue turning into AbareBlue when Gai told him to use the "Dinosaur Sentai", to Gai's dismay as he meant Zyuranger, he and Gokai Silver as DragonRanger overwhelmed Stargul before he fell back upon remembering his mission. After the fight, though they noticed his wound, Shota told Gai and Joe that he was fulfilling a promise he made with his friend Daigo to watch the shooting stars on Kamikura Mountain. Though Joe called the boy an idiot, he mended Shota's wounded leg and told him to go to his destination.

Returning to the Gokai Galleon, Doc obtained information about the black stone, revealed to be the Reiseki Warabe-ishi that when joined to its other half grants it's user limitless energy. Joe realized that the location of the other stone is at Kamikura Mountain, where Shota was headed. Fearing for Shota's safety, Joe and Gai headed for the mountain, while the other Gokaigers follow suit as Stargul combined the two stones. Fighting a group of Gormin that were keeping intruders away from the submit, Joe and Gai saved Shota. Though Gai tried to talk him into leaving, Shota refused while revealing the full story behind his promise with Daigo as Joe allowed the boy to pass to Gai's dismay. By the time they reached the mountain top, the Gokai Galleon crew found that Stargul has absorbed the stones' energy and used his Meteor Dive ability to summon an asteroid toward Earth. Transforming to negate his ability with his destruction, the Gokaigers used powers of the Goseigers, Dairangers and Ohrangers to overwhelm the Action Commander's power boost. However, refusing to give the Gokaigers the chance to destroy him, Warzu Giru impatiently fired the enlarging beam. Forming GokaiOh to save Shota from Stargul, with Gokai Blue encouraging the boy to continue, the Gokaigers formed Shinken GokaiOh with GoZyuJin supporting them in destroying the Action Commander. However, in his dying breath, Stargul revealed they were too late to stop the asteroid's course to Earth. When GokaiOh's Gokai Star Burst had no effect,

Gokai Silver had Gokai Blue use GokaiOh to throw GoZyuJin into the air, enabling the latter robot to destroy the asteroid with the Gokai Dengeki Drill Spin. By sunset, Shota managed to fulfill his promise with Daigo as they watch the shooting stars with the Gokai Galleon crew looking on. Though Gai compared his actions to the previous Sentai, Joe stated that Shota did all the work in fulfilling his dream.

GoGo V
With Navi told the Gokaigers that helping people would get them their next greater power, Gai had Marvelous help old people up steps. Meanwhile, Luka and Ahim met Matsuri Tatsumi, GoPink of GoGo-V. However, Basco was on the hunt for the power as well, having squads of Gormin cause havoc throughout the city so he could find her when she went to help. Using a Magiranger spell to disguise as Matsuri, Ahim allowed Matsuri to escape. The girls grouped up with the rest of the Gokaigers when Basco summoned Black Lion Rio, Mele and Zubaan. As the Gokaigers became GoGo-V, Gai took on Zubaan, finishing him off with Gold Mode. Basco unleashed Fireroid Meran to deal with the Gokaigers as he took his leave. When Magi GokaiOh's fire attack only made Meran stronger, the Gokaigers used the GoGo-V Keys' greater power to cool the Fireroid down before weakening him with Gokai Prominence so GoZyuJin could destroy the monster. After the adventure, Gai noted that the girls' sisterly roles had reversed, previously noting that Luka was like a big sister to Ahim.

Jealousto
Gai, along with the team, encountered Jealousto, a reformed Action Commander fought by the Gokaigers before they met Gai.

Hurricaneger
Gai decided to educate the rest of the crew about the previous 34 Super Sentais as well as categorize which Greater Powers they were still lacking. During his lecture, Marvelous, Joe, and Luka sneak away quietly to get some ice cream. He eventually comes to the aid of his friends as Satarakura Jr. and Sandaaru Jr. make their escape. Learning that Satarakura Jr. turned people into chestnuts and planning to use their power to create a missile,Gai uses the powers of BoukenSilver to track down the remaining "chestnuts." They confront the Space Ninjas, only to be defeated by them before Sandaaru Jr. become large. Gai summons GoZyuDrill and changes into GoZyuJin to combat the ninja, but was losing the battle. With the unexpected assistances from FuuraiMaru, Gai defeats Sandaaru Jr. with the Triple Drill Dream attack. He meets with Doc and Ahim as he reveals to them that Doc and Ahim were in the presence of the former Hurricangers. When asking for their Greater Power, Yousuke Shiina tells them flat out that they don't trust the pirates, especially Marvelous, Joe, and Luka and demands that they be given their respective Rangers Keys. Gai defends his friends and states that without Marvelous and his friends, the Ranger Keys would not be on Earth in the first place and they him demanding them from them was wrong. Eventually though, the team gave them their keys and awaited their return from Satarakura Jr.'s pocket dimension while battling Zangyack Agents Issan and Barizorg. They staved them off long enough for the Hurricangers to save Marvelous, Joe, and Luka and teamed up to defeat Satakaura Jr.

Jetman
The crew were in a battle against a group of giant Sugormin, and The Gokaigers used the Greater Powers of Dekaranger, Gaoranger and Hurricaneger, plus GoZyuJin's Triple Drill Dream to finish them off. Back at the Gigant Horse, Warz Gill tells his soldiers that losing countless times can be sometimes "refreshing". Until he was interrupted by Barizorg, telling his "boss" that the battle is far from over. Meanwhile, the Gokaigers stumbled upon a mysterious red warrior with a scar on his chest. Barizorg revealed that this red warrior was known as Kiaido: The Strongest Bounty Hunter in the Universe, and it seems Gai is the only one who is clueless of who he really is, as the other members of the crew (especially Marvelous) were shocked upon seeing him. It was also revealed that Marvelous did battle and was easily defeated by Kiaido, and the reason for the scar on his chest was for their battle to be "more exciting". This caused Marvelous fear, and that is why he was hesitant to face Kiaido when the Gokaigers attempted to engage him in battle.

When the Gokaigers battle Kiaido, they were still overwhelmed. As for a disappointed Kiaido, he allowed the team to re-group and leave as he saw them as weaklings. Back at the Galleon, seeing Kiaido as a very strong adversary, the crew admitted that they were no match for him, seeing that their attacks were in no effect, and they needed to to find a way to defeat him. During Don and Joe's brief arguement, Don inadvertently knocks his head with Navi's, telling the crew yet another prophecy. Navi tells them to "flare up and a bird of flames shall defeat the enemy". Luka thinks of this as some sort of hint for defeating Kiaido. Gai on the other hand thinks otherwise, as he thinks that this could refer to the all-bird themed Sentai: the Choujin Sentai Jetman. Gai further explains that out of all the Sentai teams, Jetman was the most eccentric (probably because some of its members are often seen fighting each other), and after retiring each of them were living normal lives now. Then the Gokaigers set their sights on finding the Jetmen. During the search, Joe, Luka, and Don encountered a man in a black suit and riding a motorcycle. Luka asks if this man is asking for a date. The man replied that "all women are his" and that he hates men and Nattou. He then attacked Joe and took his Mobirate then drove off. He then pursued Marvelous, Ahim, and Gai. Marvelous, seeing the man as the one who attacked Joe and stole his Mobirate, attacked him. Gai strangely doesn't seem to see who or what Marvelous was attacking. The man then asked if this is what a red warrior is now as he see Marvelous' punches too weak. He then took Marvelous' Mobilate and he revealed his name: Gai Yuki.

Thanks to Gai, the Gokaigers soon learned that this Gai Yuki was the missing Black Condor, and a former Jetman. And was wondering why he was the only one who couldn't see him. Yuki then confronted a frustrated Marvelous, calling him a brat, and telling him that the Greater Power of the Jetmen lies within him. Marvelous went on a pursuit after Yuki and ended up in a graveyard. There he saw a grave with Gai Yuki's name. Here it was revealed that Yuki was already dead a long ago. And that the Gai Yuki they faced was his ghost. Seeing that this grave was surrounded by presents from the other Jetmen members, Gai then concluded that the reason for Yuki's ghostly appearance is because he was preventing the Gokaigers from finding the other Jetmen, as they were living normal lives. He doesn't want the other members getting involved in fighting anymore. Yuki then confronted the Gormin and Kiaido. The Gokaigers arrived and they saw (par Gai) Yuki transformed into Black Condor, much to Don's confusion, as the Black Condor Ranger Key is with him. The team then faced Zangyack and Marvelous realized that the power to overcome oneself, one's limitations, and the will to overcome any obstacle, even death is the Jetman's Greater Power. Seeing that Marvelous has finally understood their Greater Power, Yuki gives back their Mobirates. And the Gokaigers transformed and engaged the Gormin and Kiaido once again. Yuki told the Gokaigers to transform into Jetmen. Gai while fighting the Gormin, having no Jetman counterpart (as they do not have a 6th Ranger), was at awe when he saw his teammates transformed into Jetmen. The Gokaigers then finished off Kikaido with an attack similar to Jet Phoenix (the same attack the Jetmen used to finish off Radiguet in their final battle). As the bounty hunter was defeated for good, the Gokaigers joined Yuki as he seats on a bench, looking up in the skies telling the team that they have his blessing and that it's their turn to protect the earth's sky before going back to the afterlife. Gai was still at dismay, as he still couldn't see Gai Yuki. Leaving him to question is it because he was an earthling.

Ohranger
After gaining the Greater Powers of the Jetman and Liveman, as well as learning about the true Greater Power of the Abarangers, the next clue to a greater power was UAOH which Gai had a hard time deducing the meaning until the Gokaigers visited an amusement park where Momo Maruo, the former OhPink of the Ohrangers found them. Gai proceeds to explain that Navi's clue wasn't Uaoh, but U.A.O.H (United Airforce Overtech Hardware), the military that created the OhRangers. Momo tells them that she will give them the Ohrangers' Greater Power in exchange for favors. However, this was all a set up to distract them from learning of Goro's plan to take back the Greater Powers that were taken by Basco. However, as time passed, she was ready to give them the Greater Power when Marvelous refused her, stating that they were pirates and they'll take what they want their way. Eventually, the Gokaigers proceed to battle Basco and his Ranger Key Clones with Gai battling the Clones of Wolzard Fire and Great Sword Man Zubaan both as Gokai Silver Gold Mode, using the Gokai Legendary Crush attack to finish them off, and with GoZyuJin when they enlarge after beating defeated. Gai defeats both Ranger Clones as he proceeds to blast Sally before she can gather all the Ranger Keys and collects them. With Basco virtually powerless now, Marvelous proceeded to attack him only for Basco to reveal a form that AkaRed feared and the Zangyack giving him a 3,000,000 zagin bounty. Gai proceeds to attack Basco but is easily stopped. Basco then twists his arm behind his back and breaks it, calling him seriously obnoxious before blasting Gai with a red and black energy, causing him to fall unconscious.

Injured, but still fighting!
With Gai's arm still broken, Action Commander Shieldon to eliminate the Gokaiger while they were weakened. As Ahim tended to Gai's broken arm aboard the Gokai Galleon, Marvelous, Joe, and Luka worked on refining their fighting skills and Doc attempted to develop a new weapon to help his shipmates. The next day, Doc tested out his modified Gokai Gun, which had an additional Gokai Cylinder built onto it, when he was ambushed by Shieldon and his troops. The other four Gokaigers arrived on the scene to dispatch the Gormin, but Shieldon proved himself to be invincible by using his Thick Face Shield to deflect their Gokai Slash attacks, along with the finishing attacks of J.A.K.Q.'s Big Bomber and the Dynamen's New Super Dynamite. Gokai Green's modified Gokai Gun also proved to be ineffective against the shield as its Gokai Cylinders exploded from the strain, forcing the Gokaigers to use the Kakuranger Keys to escape. After being inspired by a boy about teamwork, Doc asked his shipmates for their weapons to create a better weapon. Captain Marvelous and the others gave Doc their gear so he can get to work despite his warning that there was a risk that they could be attacked by Zangyack while unarmed.

As feared, Shieldon and his Sugormin attacked the Gokai Galleon the next day. While four of the main Gokaigers fended off the attackers, Doc tried to quickly finish the weapon before Gai pointed out that the weapon's frame resembles the Ohré Bazooka. With that realization, and remembering Gorou's parting words to them of using his team's power for such a crisis, Doc used the Ohranger Keys to infuse the Ohrangers' greater power into his weapon. Gokai Green entered the battle with the newly-completed weapon, christened the GokaiGalleon Buster, and the Gokaigers vaporized Shieldon with its Rising Strike attack. Shieldon was revived by the growth beam, prompting the Gokaigers to form Hurricane GokaiOh and fight the shieldless Action Commander. Despite his injury, Gokai Silver joined in the fight with GoZyuJin before Hurricane GokaiOh destroyed Shieldon. The rest of the crew noticed that Doc was noticeably more confident than usual, as he has accomplished what he set out to do this time.

Dairanger
Fully recovered from his injuries, Gai intended to make up for lost time starting with cleaning the interior of the Gokai Galleon. While shopping for groceries, Gai, Luka, and Doc encountered Action Commander Zakyura who was under orders to eat up Earth's food supply. They transformed to fight him, but he was too much for the three Gokaigers. Once the others arrived, all six Gokaigers transformed into the Gaorangers to fight with Zakyura. But Gokai Silver's excitement of being back in action left him open to Zakyura's vomit counterattack, canceling his transformation and making him drop his Gokai Cellular. Zakyura then sucked back the food, eating the Gokai Cellular as well, before retreating. Feeling depressed over the loss of his transformation device and the fact that the GokaiGalleon cannot trace its location, Gai left to have some time to himself. While walking around town, he bumped into Ryo of the Heavenly Fire Star, the former leader of the Dairangers and now an owner of a Chinese restaurant. At the restaurant, Ryo tried to cheer Gai up with a serving of his specialty gyōza, but Gai told him he can no longer consider himself a hero without his Gokai Cellular.

The next day, the rest of the Gokai Galleon crew scrambled to capture Zakyura when he resumed his mission, but he used his teleportation ability to evade the pirates. When Gai learned of the events while meeting up with Ryo with a bazaar, he expressed his frustration as Ryo tells him that he had forgotten something important to him. But before Ryo could explain more, Zakyura and his troops invaded the bazaar. Though he could no longer transform, Ryo fought off the Gormin as Gai realized that he became a hero to protect people. The two managed to dispatch most of the Gormin, but were no match for the three Zugormin and Zakyura. The five Gokaigers arrived on the scene, using the Gekirangers' Geki Infusion attack to force Zakyura to cough up everything he has consumed, including the Gokai Cellular. Gai retrieved it and joins the Gokaigers as they changed into the Dairangers and finish off the Gormin. Gokai Silver assumes Gold Mode to destroy the Zugormin and the Gokaigers used the Gokai Galleon Buster on Zakyura.

When Zakyura and the Zugormin are revived and grown, GokaiOh and GoZyuJin were summoned to battle them, but are overwhelmed. At Ryo's insistence, the Gokaigers used the greater power of the Dairangers to execute the Gokai GoZyu Qi Power Bomber on the Zugormin. GokaiOh then summoned Fuuraimaru to form Hurricane GokaiOh and execute the Gokai Fuurai Attack on Zakyura, who tried to eat the attack before it destroyed him from the inside. Back at the bazaar, Ryo gave the crew a hearty serving of his gyōza while he told Gai to never to forget the most important part of being a hero. The short lecture, however, caused Gai to miss out on the gyōza meal.

Go-Onger
While the Gokaigers were enjoying the Autumn special dinner that Gai prepared for them, a robot suddenly fell into the Gokai Galleon from a dimensional hole that opened in the sky. After it introduces himself as Bomper, the Go-Ongers' support robot, to Gai's shock. Bomper took the Gokaigers to a race track to meet the former Go-On Red Sosuke Esumi. As with all legends, Gai was most pleased to meet him. Bomper revealed to Sosuke that Gunman World is being terrorized by Barbaric Officer Chirakashizky, a surviving (and newly-recruited) member of the Gaiark Clan, and that Engines Speedor, Bus-on, and Bearrv have already tried to stop him, but were defeated instead. Sosuke asked the Gokaigers to help out, but Marvelous refused to do so, claiming that they would not get anything from it, particularly after they have already received the Go-ongers' greater power. Sosuke decided to go by himself, but after his various failed attempts to reach the hole, Captain Marvelous and the others appeared, and he said that he will give Sōsuke a ride if he wanted.

The group traveled to the Gunman World, where they save several of its denizens from a group of Ugatz. They eventually catched up with Speedor, Bus-on, and Bearrv, and learn that Speedor and Bearrv have married, and that they have a son: Engine Machalcon. However, Machalcon is a reckless troublemaker who spends his time racing around in the Machine World rather than helping out his parents. Their reunion was cut short by Chirakashizky who challenges the Gokaigers to a duel. Captain Marvelous accepted the duel, and despite resorting to dirty tricks, Chirakashizky was defeated by the Gokaigers. During their battle with the enlarged Chirakashizky, the Gokaigers tried to use the greater power of the Go-ongers, but they were surprised when nothing happens. Despite the difference in power, they managed to take Chirakashizky with their own power. While the pirates confronted Sosuke about the reason why the greater power is not working, they were contacted by Pollution President Babatcheed, the new leader of Gaiark, who revealed that he merely used Chirakashizky to lure the Gokaigers into the Gunman World, and by sealing the wall between dimensions, the pirates were now unable to return to the Human World, leaving the way open for the Gaiark Clan to conquer it.

After the Engines were unable to break the Isolation Barrier around the Human World in their shrunken state, the Gokai Galleon crew set off for Machine World to ask Engine Machalcon, Speedor and Bearrv's son, for his assistance. At first, he was unwilling to help despite his parents' pleas. When Sosuke tries to convince the Engine in his own annoying way, an annoyed Machalcon fired at the Gokai Galleon while saying that he will help if they can catch him. The Gokaigers accept his challenge as they use their Gokai Machines to pursued the Engine in his tracks. As Gokai Red pointed out that the Engine was really running away from his troubles, he had the Gokai Galleon, the Gokai Jet, and the Gokai Racer combine onto Machalcon to slow him down. Finally, admitting that his rebellious attitude is because he has been unable to find anything to fight for, and being jealous of his parents heroism, Machalcon was accepted as a Gokai Galleon crew member as he uses his power to shatter the Isolation Barrier. The pirates left, leaving Bomper and the Engines behind while promising to come back for Machalcon after handling things on Earth.

Once back in the Human World in the battle between Gaiark and Zangyack, who were surprised to see a second force invading Earth. The Gokaigers took on both groups as Warz Gill fells back so the pirates and the Gaiark could kill each other. Using the Go-Onger Keys, the Gokaigers defeated the Gaiark grunts before overwhelming Babatcheed and then using the Gokai Galleon Buster to defeat him. After activating his Industrial Revolution enlargement sequence, Babatcheed battled GokaiOh and GoZyuJin before Sosuke told the Gokaigers to use his team's greater power since they have formed a partnership with Machalcon. Summoned into the Human World, Machalcon combined with GokaiOh to form Go-On GokaiOh who scrapped Babatcheed. Soon after, as Machalcon returned to Machine World with the promise to come to their aid when needed, Sosuke was impressed with the Gokai Galleon crew's ability to befriend the previously rebellious Engine and asked if he could join their crew as well. Suggesting a name for himself, Gokai Fire, but Gai said that it had been done before.

Defeating Zangyack
After the arrival of the massice new Zangyack fleet, the Gokaigers board GokaiOh and GoZyuJin to face the massive Zangyack Empire's invading fleet, but despite making full use of the Great Powers, both are defeated, and Akudos Gill makes a statement to the people of Earth that by sunrise of the next day, the world's entire population will be annihilated by his forces. Hurt and scattered, the space pirates wander through the city helping those who are suffering from the invasion, including some familiar faces they met during their journey. While trying to save a woman covered by debris, Gai is assisted by Goushi, also known as Mammoth Ranger from the Zyurangers, who insists that the Gokaigers must use the Greatest Treasure in the Universe to protect the Earth, regardless of what would happen with the other Super Sentai heroes. Reunited at the wrecked Gokai Galleon with the others, Gai tries to convince them to make use of the Treasure to erase the Zangyack, but much to his surprise, they do not agree with him, claiming that using the Treasure would not only erase the Super Sentai from history, but also take from the people of Earth the hope and courage that they learned from them. However, they leave the final decision at his hands, and Gai ultimately destroys the Treasure with the Gokai Spear. The next day comes and Dyrandog marches forward with an army of Gormin, Zugormin, and Dogomin to start his extermination campaign, but is stopped by the Gokaigers who claim that they will face him not only as pirates, but as a Super Sentai protecting the Earth. After disposing of Dairando's reinforcements, the Gokaigers launch themselves against him.

Charging Dyrandoh head on, the Gokaigers battle the Imperial Guardsman before the Imperial fleet arrives to commence the total destruction of the city. However, Navi arrives in the Free Joker to hold off the fleet as Captain Marvelous and Gai use it to make a beeline towards the Gigant Horse while Joe and the others deal with Dyrandoh. Once inside, Gokai Red and Gokai Silver battle their way through the Gormin Soldiers before reaching the bridge where Akudos Gill admits how impressed he is that they have made it this far, but still intends to kill the pirates. As Gokai Silver holds Akudos Gill off, Gokai Red takes control of the Gigant Horse and uses its armaments to wipe out the entire Zangyack fleet. Enraged to see his fleet destroyed, Akudos Gill gets serious as he overpowers the two pirates before they damage the controls and stab him onto them before the Gigant Horse crashes. The others arrive to find Captain Marvelous and Gai all right before Akudos Gill appears, having survived the crash, still saying he will kill them all. However, with the power of the thirty-four Super Sentai teams behind them, the Gokai Galleon crew tells him that he is facing an army and has made a grave error attacking the Earth as they transform. Using various Ranger Key combinations, the Gokaigers overwhelm Akudos Gill before they become Hyper Shinken Red, Super Gosei Blue, Super Geki Yellow, Deka Green SWAT Mode, Legend Magi Pink, and Gokai Silver Gold Mode to weaken him further. However, no matter what attack they use, Akudos Gill refuses to die until the Gokaigers fire the Gokai Galleon Buster at point blank range to finally destroy him. Months later, with the city being rebuilt and news of the Zangyack Empire dissolving, the Gokai Galleon crew resolve to find the second Greatest Treasure in the Universe. On their way to the repaired Gokai Galleon, the crew meets up with the class of students they met when they first arrived and they tell them not to thank them for saving the world. But before they depart for the Zangyack homeworld to find the second Greatest Treasure, Captain Marvelous discards the Ranger Keys and allows the previous Super Sentai teams to regain their powers.

Super Hero Taisen
Gai, alongside his team, among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident when Marvelous betrayed the Gokaigers and became the Emperor of Dai-Zangyack to claim the Greater Power of the Kamen Riders.

Gai, along with Joe, Don, Luka and Ahim, arrive in the nick of time to save Kamen Rider Fourze from Marvelous, but not enough time to save his fellow Rider Kamen Rider Meteor. When they demand to know why Marvelous is doing what he is doing, he tells them that it's to save the Super Sentai by eradicating the Kamen Riders, revealing that the perpetrator, Kamen Rider Decade, had slain the Gorengers just as he had done to the Seven Legendary Riders. When Tsukasa and Dai-Shocker attack the Tokumei Sentai Go-Busters, the five Gokaigers confront them there, with Gai pointing out that Kamen Riders are heroes of justice, but makes no mention of Tsukasa's time with the Shinkengers  Tsukasa's answer is the opposite of Marvelous': to save the Riders, he must kill the Sentai. He, then, seemingly kills Gai, Ahim and Luka.

When Marvelous and Tsukasa seemingly kill Joe and Daiki Kaito, the two learn that Gai, Luka, and Ahim were still alive before being confronted by, learning that there's more to this than what they thought. Once Marvelous and Tsukasa are seemingly killed, allowing Rider Hunter Silva and Doktor J to reveal their plan to unite the Gigant Horse and Final Crisis into Big Machine and take over the worlds, the two heroes reveal their ruse and allow the heroes seemingly killed to return. During the final fight, Red1 gives Gai a brief peptalk, telling him to show Silva what a real Silver can do. In response, Eiji tosses the Gokaigers some of his Core Medals, Gai turning them into the Kamen Rider OOO Ranger Keys and becoming Kamen Rider OOO Sagohzo Combo before loading the Ranger Keys into the GokaiGalleon Buster and destroying Silva with the blast. He's last seen watching the reunions with Eiji and Hina and Tsukasa and Kaito before joining Fourze and the Go-Busters in performing Fourze's trademark "Uchuu Kita!" stance.

Super Hero Taihen
In the sections of the Narumi Detective Agency, Gokai Silver walks into Kamen Rider W's base of operations, and opens a sliding door to an Amanogawa High School classroom. Gai asked three questions to Urataros and Narutaki about Sentai and Rider Mysteries.

Go-Busters vs. Gokaiger
Gai and the rest of the Gokaigers went to the Zangyack homeworld. Due to being overrun, Gai and Navi were forced to return to Earth. When his teammates returned to Earth, he joined them in battle. But was confused why they were fighting the Go Busters. Gai was forced to hand over Ranger Keys to the others, allowing them to transform into Goggle V and Timeranger.

Summons
For attacks, Gokai Silver's been seen to somehow summon manifestations of past rangers. He is the second ever seen doing so, after Joe Gibken as Gokai Blue. However, his attacks with summons are fairly more regular, given his ability to communicate (in his mind) with the 15 warriors.

Ranger Key
The Gokai Silver Ranger Key (ゴーカイシルバレンジャーキー) is Gai's personal Ranger Key which allows him to transform into Gokai Silver. Whereas the keys of the 34 Sentai were created out of the sacrifice of their powers in the Great Legend War, with the five Gokaiger Ranger Keys assumed to have been created by AkaRed. Gokai Silver's powers were created by Mikoto Nakadai (AbareKiller), with Burai (DragonRanger) and Naoto Takizawa (TimeFire), as all three were deceased previous Sixth Rangers.

As with the other Gokaiger Ranger Keys, this key is commonly used in the Gokaigers' Ranger Key-compatible arsenal and mecha for different functions and attacks.

This Ranger Key was turned into a Ranger puppet once, by Basco. Along with the other Gokaigers bar an incapacitated Marvelous, Gai confronted and defeated the puppet Gokai Silver.

Bounty
Gai's initial Zangyack bounty is 100,000, which leaves Don dismayed that the newcomer already had a bounty that was twenty times his. Due to his role in the death of Warz Gill, his bounty was increased to 300,000. .

Imitations
The shape-shifting monster Vannain took the form of Gokai Silver while fighting with Gai. The Gokaigers were confused as to which one was which, but Luka had an idea. The Gokaigers changed into the Megarangers, with the real Gokai Silver becoming MegaSilver, leaving Vannain exposed as the fake.

Portrayal
Gai Ikari is portrayed by Junya Ikeda (池田 純矢). As with his character, Junya is also a fan of Super Sentai. He stated in his blog that when he was a child he wanted to be KibaRanger from Gosei Sentai Dairanger. In episode 19, the first thing Gai does when he is allowed to summon Ranger Keys is to summon the KibaRanger key. Three episodes later, Gai finally transforms into KibaRanger.

In the Korean dub of Gokaiger entitled Power Rangers Captain Force, Gai is voiced by Nam Doh-hyeong (남도형, 南度亨).

As Gokai Silver, his suit actor is Daisuke Satō (佐藤 太輔), who later served as suit actor for Beet J Stag/Stag Buster in Tokumei Sentai Go-Busters.

Etymology

 * Gai's name sounds similar to Gaia, the primordial Greek goddess or personification of the Earth, which may be a reference to the fact that he is the only Earthling on the Gokaiger crew.
 * His surname, "Ikari", is pronounced the same as the Japanese term for "Anchor" (錨), which is a feature exhibited in much of his arsenal, from his personal symbol to one of his weapons' alternative forms,
 * Gai's given name means "Armor", referencing Gold Mode. His name is actually an alternative pronounciation of the kanji, with the common-most one being "Yoroi", with that being why Sosuke called Gai "Yoroi".

Counterpart notes

 * Gai shares a few things in common with 3 out of 5 of the other Gokaigers in terms of counterparts.
 * He is one of three Gokaigers to not have a counterpart from every previous Sentai team, the other two being Don and Ahim. However, of the three, Gai is the only one who does not have a counterpart from any of the pre-Zyuranger teams (instead of just Sun Vulcan).
 * He is one of two Gokaigers with no counterpart that was either an official or technical leader of their team, the other being Joe. Though, in Gai's case, no Sixth Ranger in Super Sentai has ever been the leader of a team, as they would always appear later on in the series, unlike in Power Rangers.
 * He and Joe each have a counterpart played by Shiro Izumi. In Gai's case, his is DragonRanger from Kyōryū Sentai Zyuranger.
 * He and Don share the same amount of Red Ranger counterparts (1).
 * Ironically, even though Gai is a happy-go-lucky team player, most of his counterparts (DragonRanger, TimeFire, GaoSilver, AbareKiller, Bouken Silver, the Go-On Wings, and Gosei Knight) were hardcore loners.
 * His cooperative counterparts include KibaRanger, KingRanger, MegaSilver, Shurikenger, DekaBreak, MagiShine, and Shinken Gold.
 * Gai has the following quirks that make him unique among the Gokaigers concerning his counterparts:
 * He is the only Gokaiger to have more than one counterpart from a Sentai team. In this case, Engine Sentai Go-Onger with 2. However, as there are only 6 Gokaigers and 7 Go-Ongers, whenever there is a Go-Onger team change, he changes into the Go-On Wings; half and half of each counterpart.
 * He is the only male Gokaiger to have any White Ranger counterparts.
 * Despite having the least amount of counterparts compared to the others, Gai has the most amount of different colored counterparts out of all the Gokaigers.
 * Bakuryuu Sentai Abaranger is the only Sentai team where Gai has a counterpart while one of the main five doesn't. In this case, Ahim (unless you count AbarePink).
 * Because all of Marvelous and Don's counterparts are male, Gai has the least amount of opposite gender counterparts, as Go-On Silver is his only female counterpart. Ironically, she is also the only Sixth Ranger Gai has never transformed into.
 * He is the only Gokaiger to have all his counterparts appear in Power Rangers, as Kyōryū Sentai Zyuranger, which is the first Sentai to be adapted, is where the Sixth Ranger trend officially started (although Bioman and Maskman both had predecessors to the Sixth Ranger).
 * Ninja Sentai Kakuranger, Gekisou Sentai Carranger, Seijuu Sentai Gingaman, Kyukyu Sentai GoGo-V and Juken Sentai Gekiranger are the only post-Jetman Sentai teams where Gai does not have a counterpart.
 * However, he is the only character to use the Black Knight key, even if he is considered a Bangai Hero and not a 6th.

Gokai Change notes

 * Gai is the only Gokaiger whose first in-series Gokai Change was neither his color (silver) or the first Ranger that can be considered his counterpart (DragonRanger).
 * Although it may just be coincidence, the first Ranger he changed into, KingRanger, was a Black Ranger. This is also the same color as Magne Warrior, the first of the two "prototype" 6th Rangers.
 * Likewise, like the Gokaiger's first in-series transformation were the first Sentai ever in the viewer's perspective (the Gorengers), Gai becoming KingRanger may represent him becoming the first Sentai character in existence in-universe. KingRanger was active 600 Million years prior, long before the second-oldest Sentai in existence: the six Zyurangers.
 * Coincidentally, his first silver Gokai Change was Bouken Silver, the Sixth Ranger of the last anniversary series, GoGo Sentai Boukenger.
 * Of the 5 Sentai Warriors whose Power Rangers counterpart is Tommy Oliver, AbareBlack is the only one Gai has not transformed into.
 * Gai is the only Gokaiger besides Marvelous to use all of the Red Ranger keys. This is thanks to the special DVD, Kaizoku Sentai Gokaiger: Let's Do This Goldenly! Roughly! 36 Round Gokai Change!!, where he transformed into all the red heroes from Akarenger to Gokai Red. Although this was when Gai and Marvelous were combined into one body, which was essentially Marvelous with Gai's dress sense, the two of them were both in the mind and it was Gai who was in the driver's seat when he performed these changes. If one doesn't count this, he has only changed into DekaRed (48) and Go-On Red (Go-Busters vs. Gokaiger)
