Saiki scares the hell out of me. So much flash in his corner combos, and that's without HD. He can anti-air you and put you back in that corner at the same time, he has a good FB game, he has teleports (not Marvel level mind you, they can be seen coming but still), a command grab DM, decent pokes and he's androgynous as hell (though less so than his successor Ash).
I mean, not calling out god tier or anything, I'm sure he has his flaws, plus his only good damage seems to come in the corner, and he DOES need meter/Drive usage for it, but still...I'm watching out for him (and...putting him in one of my teams somewhere lol)
