I don't understand how anyone could think Spiky's Bankai is anticlimatic. It blew my mind when I saw it! Anyways, at the end, they seemed to be hinting that Spiky didn't even use all or any of his Bankai. Sure, he's got speed, but his sword hasn't done anything yet. I think the best is yet to come. C'mon... you gotta love that new soul slayer appearance. I think the whole point is that Spiky calls on Zangetsu to help him and they're basically in tandem while the others seem to order their Bankai around, but not work with it sort of deal. Same idea as the big dude Spiky beat up. You know, with the little pink bubblegum girl. Oh man, is she gonna fight?
