Seriously I am not lying to you. He is a ninja. And a damn awesome one!
He can make himself invisible.
When he's stealthy he doesn't move around in his System Changed mode he moves in his Police Cruiser mode.
HE'S A POLICE CRUISER! WHAT BETTER CAMOUFLAGE IS THERE?!
Seriously. If you don't believe he's an awesome ninja. Watch him in action.
