Alpha possibly has the worst defense out of the entire cast. I don't see people using that to their advantage enough, heck even if she successfully counters you & lands that weird dash in attack afterwards it does practically no damage. Not much of a risk in comparison to other characters counters so I just stay in her face.
Using her against the really fast characters is seriously painful hahaha, least other characters have a defense against it Alpha just kinda has to deal with it and hope they find a point to interrupt her opponent.
