no, please stop...
the models used in konquest and in the prison level aren't up to par with the ones used in the actual fighting portion of the game, which is why Kintaro, Motaro, Shao Kahn and Moloch seem smaller in Konquest/prison and in the Shokan character's cases, are missing two arms.
Every character (in the walking around portion at least) in Konquest has the same 'wireframe' with a skin laid over it, thus they're all the same size/shape
there is no super-unlockable... the mods have said this, even the team partially admitted it on fight night...
