How is there no rampant pointless speculation in this thread? You'd think given how this dude was in MK9 people would be all like "WHAT'D THEY DO!?" Well, I'm bored as fuck and hoping they'll show him off soon. So personally I'd like to see something vaguely like:
Variation A - Hybridizes sword and spirit stuff (i.e. uses TK to bolster sword range), focuses on mid-screen footsies stuff, whiff punishment and all that, maybe not particularly safe or might lack a mixup game. Think this would probably be the style where armor comes into play.
Variation B - pure zoning style, all that tele-flurry/slash/rising karma/spirit charge hilarity. But no armor/reversal, minimal close range effectiveness and lame combos without a corner.
Variation C - mix-up/pressure/frame-trap, etc style based almost entirely on the katana/Bushido with very limited spirit/TK stuff. Maybe have like a little meter that builds as you do damage/land block strings that lets you throw out some huge ass Dhalsim-Ultra style spirit ball that covers your shit in the corner or can cover your advance, since you'd be vulnerable to zoning here.
I don't have a problem just coming out and saying what I want for this guy since I figured Raiden with lightning traps was farfetched and then BOOM, it totally wasn't. You heard it here first.
