Gaisoulg

Gaisorg (ガイソーグ) is a mysterious knight dedicated to finding the strongest warrior among the Super Sentai.

Super Sentai Strongest Battle!!
Gaisorg 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 Gaisorg to attack next.

Gaisorg 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. Gaisorg attacks the duo until Marvelous arrives to fight him. Gaisorg 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 Gaisorg reveals he is in possession of one. With no other choice, Rita inserts Gaisorg into the competition as a wild card. Between rounds, Gaisorg confronts Takaharu and attacks him. Gaisorg 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 Gaisorg but were all defeated until Marvelous arrived and fought him as Gokai Red then as DekaRed and HurricaneRed. Gaisorg prepared to use one of Takaharu's techniques but was deflected by Marvelous who was able to unmask him, revealing Takaharu Igasaki inside.

After Ultimate Dai-Satan is defeated, Rita summons Gaisorg's armor to fight against Marvelous, Stinger, Takaharu, Kagura and Yamato. RyusoulGreen and RyusoulBlack appears and finish off Rita by destroying Gaisorg's armor in order to release her. After Gaisorg's armor has separated into pieces, a mysterious individual manages to take Gaisorg's helmet.
