Um, I can think of a couple such characters. I personally think it's a rather cool special ability, aside from the special abilities summoning weapons from nowhere, and Mind Control. Here's some others I can think of. Bryce Boltzmann (Neverdead) Deadpool Rayman XJ9 Jenny (My Life As a Teenage Robot) Alisa Boskonovich (Tekken)
a word of advice. Get the devensive offense ability and the air guard impact before you fight this asshole. And beef up the polearm as much as you can. it is your best friend against this asshole. He likes to run around you and attack your back side. The polearm attacks in a circle motion so its alot safer. the defensive offensive is a sidestep slash VERY good for quick escape. and finally the Air perry is really only for monsoon i found. If he lands that launcher kick and you dont have it he slamms you to the ground and stabs the shit out of you. So air perry stops that plan dead.You'll take damage from the launcher kick but atleast you wont be slammed.
Use electric grenades when he starts spliting himself apart then use blade mode and hit the right spot to make him fall apart, if you need more help try watching the youtube walkthroughs thery're very helpful
