Gogo. He can pretend to be anyone so he would play a very tactical game and win.

Celes would commit suicide with the stress of it all. :x_x:
Terra would morph into an esper and fly away.
Locke would be too busy over rachael and would get :chop: by shadow.:x_x:
Edgar would get arrested for sexual harrassment
Sabin would die due to overusing his "bum rush":x_x:
Kefka would be immediatly voted off for his grating laugh.
Relm would create another version of herself by doing a self-potrait.
She then realizes what an annoying little she is and thrusts her paintbrush through her heart.:x_x:
Seing his poor little daughter dead drove Strago to comfort eating. Too bad shadow offered him a poisened
Setzer would get the slot combination that kills him.:x_x:
Umaro and Mog get suspicious of Shadow, so they repeatedly hit him on the head with sticks until he dies. :twak: :x_x:
Turns out shadow didn't kill anyone and it was Gogo pretending to be shadow. He then convinces them that he is Aldai Stevenson and they both die of shock. :surprised
Gogo walks away as the champion!!! :strut:
