Windstar
[13] Hero
Anyway. It looks like he took Necrid's old 3BB. The extra footage after the demo seems to suggest he has a broken-esque boss form, complete with a new CE. That boss form probably isn't going to be playable; but it seems like something to mess around with.
As note, I think he'll be character 21 or 22. I'm not quite sure he'll have a Story Mode, but there's a good bet he probably will.
