So early review of Black Manta as I have been playing him today:
Damage is not that great yet but could be due to scaling on flight cancels, or scaling on rockets.
D1 is 7 frames... BOO.
No real crossup.
Easy 330+ damage on jump 3, b11,u3, flight, 1,3, bf 2.
Has some DIRTY mixups kind of like Red Hood hard to blockables.
F2 will be useful getting in on opponents, if I remember correctly it's only -2 (that might be with the 1 followup) and very fast startup, long range.
B2,2 is a low starter. Slow startup and -4 on block if I remember correctly. Possible gap in string.
2, d1. Low on second hit.
"Zod strike" which is what I call it can be done in air, along with rockets, and Harpoon.
MB teleport punch is hard, maybe impossible to B3 or F3 from. Use b11 starter to continue combo.
Bf1 is eye laser and cause crumple state on MB. Can't find combo potential. Zod strike seems to be best combo ender. Harpoon creates a lot of distance between you and opponent. Can get all 3 air attacks in 1 flight, not sure about holding button down though it's used to stay afloat.
So far, very fun character. Damage is kind of lacking but seems like he's balanced as you can do some dirty shit to your opponent (especially in corner).
