Part of the Brave Police, he can combine with his motorcycle, the Gun Bike to form GunMax Armor, or transform with his GunBike to form the Max Cannon for J-Decker's use. Unlike the other Brave Police units, GunMax does not have a vehicle form, instead riding a large motorcycle called the GunBike. He originally came off as being overconfident, cynical and sarcastic, preferring to operate alone and shuns others.
