Gaisorg

Gaisorg is a mysterious villain appearing in 4 Week Continuous Special Super Sentai Strongest Battle!!. He is a member of the Druidon Tribe who enters the Super Sentai Ultimate Battle in order to fight the Sentai warriors. He apparently has a history with Captain Marvelous, but the details are unknown.

History
Gaisorg first showed up after the Super Strong Team won their match against the Curveball Team, swiftly beating down all five members of the winning team before heading off, leaving the other teams mystified as to who he was. Marvelous however, recognized him and told the other members of his team who he was.

Gaisorg later managed to enter the Ultimate Battle legitimately by presenting Rita with a golden tablet of his own.
