|“||I'm no Maverick. I'm in complete control of myself and my actions.||„|
|~ Gigavolt to Axl|
Gigavolt Man-O-War, is one of the eight Mavericks that are fought in Mega Man X8. He is one of the new-generation Reploids who turned Maverick and joined Sigma's rebellion. Despite believing he is not a Maverick, he still wishes to help Sigma by siphoning energy from Megalopolis. No matter who confronts him, he will always believe he is not a Maverick.
The entire stage consists of the player chasing Man-O-War in between the buildings of Gigalopolis on a hoverbike. After he's taken enough damage he will stop on a floating platform and the actual boss fight begins. He will float around and sweep across the arena, shotting lightning from his hands and releasing small jellyfish drones which track the player. Once he's low on health he will position himself above the arena and discharge lightning to strike the platform at various points. His weakness is the Crystal Wall.
