My initial thoughts on Alex, just based off my really quick time with him in Training and completing his Trials:
Seems much, much slower and less nimble than his Third Strike version. His backdrop off HP.chop timing is different so it threw me off at first. It almost feels like a buffer/one motion. His special Headbutt attack actually feels incomplete--is there a way to follow up off of it? His LK stomp jumps over people really up close so shenanigans seem out. V-Trigger looks like it can set up some messed up combos--Brutality potential high! Lastly, HATE HIS NEW VOICE.
