Nova is reminding me of Taskmaster in some way, I just can't think of it right now...
Anyways, Nova looks like he does solid good damage (not truck, more like hummer lol) and as Seth mentioned in a video, the generic "boring" beam hyper has extra effects like moar damage (he mentioned damage of a lv3 super for 1 bar).
Nova is fairly solid right now, Phoenix Wright on the other hand is just LOL.
PW reminds me of what Servbot should have been in MvC2. His lv.3 is just weird IMO, and dat Sentinel stage is amazing!!! (Sentinel + Sentinel stage = WIN!)
