Dome Borg is the fifth active Gerrok Techadroid Borgs, created when Gerrok Card 11 infects the East Stadium. The largest of all the Techadroid Borgs, whether or not they are Gerrok Techadroid Borgs, Dome Borg sucked Red Cheetah BattleZord into a subspace within himself to subject the Megazord and its pilot to fighting a gauntlet match against his Megazord counterparts. Once exposed, Dome Borg is destroyed by BugMax Thunder Megazord.
