Series: Rockman X
A side villain in the X series. A mercenary and general troublemaker, Dynamo works for Sigma in X5, and hangs around Nightmare areas in X6. He doesn't fight to the death; he's probably not even a Maverick, just a jerk.
Dynamo is unlikely to return, but remains a fan favourite. He has the distinction of being the only boss who adapts his fighting style to the character you're using (X or Zero), and in X6 he hits Zero with one of the funniest lines in the series: "You must be busy dying so many times."
Nobody here but us chickens!
