Robot Storm|ロボットストーム|Robottosutōmu}} is a sentry robot troop and the second enemy gauntlet in Sonic Heroes. |game = Sonic Heroes |level = Mystic Mansion |description = A more difficult version of Robot Carnival. |previous = Team Battle 2 |next = Egg Emperor
This battle is generally more difficult than Robot Carnival; as the battle is longer and the enemies are larger, stronger, and sometimes faster. This boss is notably easier for Team Chaotix, due to their Team Blast, Chaotix Recital, which adds rings for every enemy destroyed on the field. The rings allow the move to be performed again. Team Rose only faces four waves. Team Sonic and Team Dark face three Egg Hammers after a wave that consists of one Egg Hammer.
