sweetness dude.
also, Zero...
mmm... maybe bring the Buster back? X7 and 8 are sorely missing it...
yeah. the buster I say... either a regular charge buster like X's, or the buster he had in X2 and 3. or even minus the saber part. just a double shot buster.
as for actual MOVES, then may I suggest the K- knuckle?
I mean, it would be easy to edit the buster double shot sprites to punching, and add the shoryuken to him, I mean, he didi it in X8...
although I think X needs something more... It feels like he's lacking something, though i cant place what...... maybe one or two more meele moves. maybe shoryuken, or some variation thereof I mean, zero has that downwards punching thing no? X (or Zero) could be given shoryuken, so they do that, and follow up with the downwards attack.
