Break is the third boss from Streets of Rage 3.
Details
Break is an evil robotic clone of Axel Stone, used to frame Axel for the kidnapping of Ivan Petrov. Appearance-wise, he's an exact duplicate of Axel, save for the fact that he wears purple (blue in the Japanese version) gloves, whereas the real Axel wears red gloves.
He possesses many of Axel's attacks. He can do a somersault attack unlike the real Axel, who has to do it as a team attack. His attacks are more in form of a dash or shortened from Axel's movelist. Axel's pick up slam is replaced with the clone's German suplex, which the real Axel has not possessed since the original Streets of Rage.
Break also appears as a solo enemy for Axel in Project X Zone 2, being brainwashed by M. Bison's Psycho Power until Chapter 40: Iron Fists of Fury, where due to Bison's death 2 chapters ago, he is free and has Mr. X's soul inside him, desiring to revive the Syndicate, but is stopped by Axel and the Shinra team.
