I didn’t really get a chance to work on combos, so I was just throwing the specials out there in order to get a hang of Nova’s moveset. They generally seemed decent in terms of damage and priority and especially combo potential, though. I don’t know what’s safe or not, though, so I can’t really say if any of the moves are actually viable. I might have mixed something up here and there, too, since it’s been a long day, but I think it’s mostly correct. Someone else can feel free to append the proper move names and input icons and stuff.
crouching B: slide, special cancelable.
Crouching C: looks like Cammy’s sweep (if I’m thinking of the right move), unsafe.
Toward + C: ground pound punch, can be charged by holding down the button, which makes it cause OTG and allows you to combo after. I guess it’s like that Super Skrull move.
Air S: downward diving punch, does multiple hits.
qcf + A = mid range projectile, hits in front. Air OK. Doesn’t seem remarkable, but might have some use I guess. I’m pretty sure this is a recycled animation from Storm and Iron Man.
qcf + B = same move, but angled upward. Air OK.
qcf + C = Nova creates a shield/barrier. Similar to Modoks in terms of speed and duration: not amazing. Red health is used to produce a larger version of the shield that lasts longer. This is one of his assists.
dp + A = Rushing slide attack, causes OTG. Pretty sure Nova can combo after it on his own. This is also one of his assists.
dp + B = Nova shoots up and does a dive kick (not an overhead) that you can combo out of on hit.
dp + C = Nova rushes forward and uppercuts the opponent, super jump cancelable. Reminds me of Captain Falcon’s side + B in Smash.
Most of the above moves are fairly slow on start-up, but travel quickly and seem to have good priority.
qcb + A = rushing attack. I think this version is comboable, because it doesn’t do much else.
qcb + B = rushing attack, causes wall bounce that is easily comboed off of. Air OK.
qcb + C = rushing attack, causes crumple. This special seemed pretty solid–it’s probably unsafe as hell, but it moves really fast, does good damage, and the crumple is beast. I was doing it on reaction to assist calls and crumpling two characters at once. Pretty sure this works in the air.
Like the DP input specials, all of these moves have a bit of start up but travel relatively fast.
Air dash: horribly slow, and swerves around like Morrigan’s.
I couldn’t figure out how to control his Rocket Blast/Maximum Nova super… the input is qcb, though. Beam is qcf, and Inferno is DP.
