Gunmax

A sentient police robot that does not transform on his own. He is from Traffic Patrol Division. As a quite independent robot, he refuses to work with him at first. However, when Yuuta almost sacrificed himself to save Gunmax, he is touched by Yuuta's genuine love and join the team. He often uses English when he talks, and is one of the most care-free character of the story. Time to time, he refers Yuuta as "kid" and he has a special relationship with Toudou, the development chief of the Brave team.
