I really like omega Oni, he’s got a lot of new juggles, which is interesting. Not to mention his damage is beefed up now.
So, his basic punish combos seem to be:
Meterless
B. Hp, TC2 xx Lk tatsu, Hp dp midscreen [326 Damage, 438 Stun]
B. Hp, TC2 xx Lp dp, Hp dp in the corner [368 Damage, 508 Stun]
B. Hp, TC2 xx Hk tatsu, Hp dp near the corner [344 Damage, 478 Stun]
For 1 Bar
B. Hp, TC2 xx new ex hadoken, Hp dp midscreen [361 Damage, 473 Stun]
B. Hp, TC2 xx EX tatsu, F. Hk, Hp shoryu in the corner (this works on Ryu, but I can’t get it on Akuma for some reason, may be character specific, or I may be bad) [410 Damage, 588 Stun]
For 2 Bars
B. Hp, TC2 xx Lk tatsu, EX dp midscreen [446 Damage, 528 Stun]
B. Hp, TC2 xx Lp dp, EX dp in the corner [488 Damage, 598 Stun]
I also found a couple of really cool combos on T. Hawk. These don’t seem to work on Ryu, so maybe it’s big body only?
B. Hp, TC2 xx Lp dp, F. Hk, Hp Dp in the corner [396 Damage, 588 Stun]
B. Hp, B. Mp, TC2 xx Lp dp, Ultra 1 [434 Damage, 362 Stun]
Oh, and all instances of Hp dp, except for after a F. Hk, can be replaced with Mk. tatsu. Lowers damage but increases corner carry which is nice. That’s all I could find so far. I’ll keep labbing it up though.
