Retsu Fukami

Retsu Fukami (深見 レツ) is GekiBlue (ゲキブルー) of the Gekirangers. He is an employee of SCRTC and a Fierce Beast Jaguar-Fist (激獣ジャガー拳) practitioner.

Gekiranger
He was a child when his older brother Gou Fukami was believed to have been killed by Rio. This event traumatized Retsu severely, to the point where years later he still possessed an utter hatred for Rio. He originally had a promising career in painting but took a break to learn the same fighting style as his older brother had to find the same motivation that it gave Gou, rather than out of revenge. Retsu is very intelligent but also selfish, doesn't take interest in others, and gives an impression of extreme coldness, although this changes as the series progresses. He believes that winning should be like a painting, complete and something that moves you. He sometimes mixes English when speaking. He learned of moving sensation of a trance when he mastered Bat Li's Fierce Beast Bat-Fist (激獣バット拳, Gekijū Battoken) style. He knows various "Techniques" (技, Gi, also pronounced as Waza), putting them in first priority when training. His attention to beauty costs him stamina, making his "Body" his weakest point until he competed with Bion Biao in an endurance match (and emerges victorious) to obtain Extreme Ki. This training allows him to become Super GekiBlue (スーパーゲキブルー). As Super GekiBlue, he uses the Fierce Beast Gazelle-Fist (激獣ガゼル拳) style and is the "Extremely Fantastic Technique" (「過激にファンタスティック・テクニック」).

During the final battle, Retsu is infused with Rageku's Confrontation Ki, and is then brought to an astral Confrontation Beast Hall to master the Confrontation Beast Jelly-Fist (臨獣ジェリー拳), style to seal Long. Three months after Long's defeat, he is seen alongside Ran Uzaki teaching the Beast Fist to young kids at SCRTC.

Legend War
A few years later, Retsu fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. Retsu with Ran is one of several rangers (portrayed by a stand-in) who could be seen in the background when the Goseigers awoke after sacrificing their powers.

Farewell Space Pirates
After the defeat of Ackdos Gill, Captain Marvelous returned all the Ranger Keys to the former Sentai heroes. It is assumed Retsu and his teammates received their keys allowing for them to utilize their powers once again.

Super Hero Taisen
Retsu, alongside his team (Rio and Mele were absent), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker. During the final battle, he is seen fighting Zatsurig and Alligator Imagin.

Super Hero Taisen Z
The Gekiranger trio were among the various superheroes that came to help during the crisis, having been summoned by Gai Ikari. They appeared with the Livemen and Gingamen to aid against a Space Shocker force led by.

After was destroyed, the Gekirangers appeared on a cliff alongside all the other past heroes to say goodbye to the heroes of recent years before taking their leave.

Ranger Key
The GekiBlue Ranger Key (ゲキゲキブルーレンジャーキー) is Retsu Fukami's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The GekiBlue Ranger Key was mainly used by Joe Gibken (Gokai Blue), who used it to fight as GekiBlue.
 * When the Gokaigers became the Gekirangers in their fight with Cosmic Kenpō Master Pachacamac XIII.

 * When the Gokaigers became the Gekirangers while fighting Action Commander Zakyura.
 * When the Gokaigers became the Gekirangers and RinJyuKen Warriors while fighting Zangyack shortly before the team found out that Don was apparently a legendary hero.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Retsu received his key and became GekiBlue once more.

After transforming into Geki Blue, Retsu says, "The great blossom colored with technique. 'Fantastic Technique,' Geki Blue!" (技が彩る大輪の華 「ファンタスティック・テクニック」 ゲキブルー！). After transforming into Super Geki Blue, Retsu says, "'Extremely Fantastic Technique,' Super Geki Blue!" (「カゲキにファンタスティック・テクニック」 スーパーゲキブルー！).

Imitations
The doppelganger of Retsu was created by Shiyuu. He used it as a revenge for Retsu cracking Shiyuu's armor with GekiFan. When he is in the shower room, he looks at himself in the mirror, when he turns away, his reflection moves differently. Retsu gets confused, touching the mirror, and the reflection pulls Retsu into the mirror. The doppelganger of Retsu was played by the twin brother Shinpei Takagi.

Portrayal
Retsu Fukami is portrayed by Manpei Takagi (高木 万平). He has an identical twin brother Shinpei Takagi who played a copy of Retsu in Lesson 38. Shinpei later appeared as Takuma Tsuzuki/AkibaRed II in Hikonin Sentai Akibaranger, their connection is referenced when Kozukozu says Takuma looks like Retsu, but Nobuo says they look nothing alike. As GekiBlue, his suit actor was Yasuhiro Takeuchi (竹内 康博).
