Character History

According to Bamba, Gaisoulg was created by the RyuSoul Tribe to fight the Druidon, however at some point the armor developed it's own consciousness. Ep. 21: Light and Dark Kishiryu Master Green would later don Gaisoulg's armor against some returning Druidons, but ultimately, the Armor found his weakness and managed to control him, causing him to attack his own village. Unable to deal with it, Master Green fled to outer space and died off, leaving Gaisoulg to wander the cosmos looking for a strong opponent. Eventually, he ended up on planet Nemesis. Ep. 30: Overthrow! High Spec

Super Sentai Strongest Battle!!

Gaisoulg is an armored Ranger-like knight who bears more than a passing resemblance to the Ryusoulgers. He has been searching for the strongest among the Super Sentai, and initially sought out the Gokaigers. Dissatisfied with them, he leaves. Later he infiltrates the Super Sentai Strongest Battle, a friendly competition among Rangers to discover the strongest warrior and grant their wish, in order to achieve his ends. Captain Marvelous also receives an invitation to the battle and surmises correctly, that it is the perfect place for Gaisoulg to attack next.

Gaisoulg then proceeds to attack some of the skirmish winners, until he gets to Stinger and Takaharu Igasaki, who happen to be part of Captain Marvelous' component.Battle1: Who is the Strongest in History!? Gaisoulg attacks the duo until Marvelous arrives to fight him. Gaisoulg is able to defeat him but before delivering a final blow, Takaharu deflects one strike and is hit by the other. He decides to leave afterwards and is summoned by Rita, the guardian of Nemesis who created the competition. She says that only those with an invitation are allowed to participate but Gaisoulg reveals he is in possession of one. With no other choice, Rita inserts Gaisoulg into the competition as a wild card. Between rounds, Gaisoulg confronts Takaharu and attacks him. Gaisoulg is sent into the fight between NinjaWhite & RyuuRanger vs. Red Mask & OhRed in order to speed things up. The four Rangers anticipated this and teamed up to fight Gaisoulg but were all defeated until Marvelous arrived and fought him as Gokai Red then as DekaRed and HurricaneRed. Gaisoulg prepared to use one of Takaharu's techniques but was deflected by Marvelous who was able to unmask him, revealing Takaharu Igasaki inside.Battle2: The Secretive Armor of Mystery

After Ultimate Dai-Satan is defeated, Rita summons Gaisoulg's armor to fight against Marvelous, Stinger, Takaharu, Kagura and Yamato. RyusoulGreen and RyusoulBlack appears and finish off Rita by destroying Gaisoulg's armor in order to release her. After Gaisoulg's armor has separated into pieces, an unseen person[2] manages to take Gaisoulg's helmet before making his leave.Final Battle: Heading Towards Tomorrow!


Nada, now under the identity of Gaisoulg, released Kishiryu DimeVolcano for Wizeru, however the Kishiryu was obtained by the Ryusoulgers first. The night after the Ryusoulgers defeated the Shen Minosaur, Gaisoulg met with Wizeru and Kureon mocking the first for allowing the Ryusoulgers to obtain DimeVolcano, which made Wizeru angry and had a small fight with him. Angrily Wizeru asks him why he didn’t got rid of the Ryusoulgers by himself which Gaisorg responded that it was pointless as Wizeru wanted "entertainment". Gaisoulg tells Wizeru that he's going to let him know if he finds something interesting before leaving. Ep. 12: Scorching Illusion

Gaisoulg later approached Prime Minister Mioko Karino at her hospital room who tells her that he could have killed her if she wanted. Mioko responded that she and Gaisoulg are similar as both wander with nowhere to belong. Mioko tells Gaisoulg that he might be having trouble to let his past glory go and according to her, Gaisoulg could create a Minosaur by this rate. While Mioko leaves, Gaisoulg asks her where she’s going, to which she answers where she belongs as she finally found her place. Ep. 13: The Prime Minister is of the Ryusoul Tribe!?

After a seven episode absence, Gaisoulg returns by meeting face to face with Towa who was the last Ryusoulger standing as the others were captured by Wizeru with the power of the Grimoire Minosaur. Gaisoulg had a small battle with Towa in which he easily defeated him. Before leaving, Gaisoulg told Towa “to not rely on his strengths and bring them to life instead” which were the same words that Towa and Bamba’s master used to say.Ep. 20: Supreme Artist


Not much known about his personality. It is shown that he is a merciless and sadistic knight who wanted to defeat his enemies without any villains' help. He is also one of the Sentai villains with a loner-type personality.


These persons used the armor and unlike the hosts, they have full control over it or they still have control over their actions.


These persons were forced to wear the armor against their will and while using it they had almost no control over their actions, depending on how many parts of the armor is worn, like Captain Marvelous, who partially held-in the armor's essence until he freed the others that it captured.

Behind the Scenes



  • Gaisoulg continues the tradition of a knight-themed Sentai Villian featured in a dinosaur-themed Sentai series that began with Dora Knight from Kyōryū Sentai Zyuranger. Other characters include the Armor of Darkness from Bakuryuu Sentai Abaranger and Raging Knight Dogold from Zyuden Sentai Kyoryuger.
  • Gaisoulg's armor resembles the Ryusoulger's suit and his sword is a silver-and-purple version of the Ryusoul Ken.
  • The details on his armor give him the semblance of a human-sized RyuSoul in Knight Mode.
  • Gaisoulg shares many notable similarities with other knight-themed characters, most notably Wolzard, The Armor of Darkness and Raging Knight Dogold. In regards to Wolzard, both wield a sword and shield weapons and both feature a similar purple & silver color scheme. In regards to the Armor of Darkness and Raging Knight Dogold, these are sentient suits of armor which enslaved their hosts and gives them access to their weapons and techniques as well as the skills and techniques of their victims.
  • The Japanese pronunciation of his name (Gaisōgu, ガイソーグ) is similar to Kaizoku (カイゾク) with little difference of sound. Although people don't usually use Katakana for spell Japanese word in Hiragana, it's written as かいぞく and in Kanji write as 海賊 which means "pirate".
    • His name might also be derived from the Japanese word Gaisou (外装), which means "sheath".
    • Part of his name, Gai, is a kun'yomi reading for the kanji "Yoroi" (鎧 lit. "armor").
  • Despite not being part of the Druidon Tribe, Gaisoulg's Knight motif plays into the Chess theme shared by almost all main members of Druidon.
