Orange Hulk
This guy is fairly decent. He gave up his super armor for some proper speed. Most people would prefere this form, but you can use either just as effectively as the other.
Special Attacks
Ground Wave - QCF+P
Gamma Charge - [B], F+K or [D],U+K
Gamma Tornado - HCB+P
Super Attacks
Gamma Wave - QCF+2P
Gamma Crush - QCB+2P
Gamma Quake - QCF+2K
Combos
D+FP, QCF+2P
This is an easy set up into the Gamma Wave. Make sure that you only hit once with the D+Fp or the combo will not work.
D+FP, QCF+2K, QCB+2P
This is a deadly combo. First, use the D+FP. One or two hits, it doesn't matter. I think only using one hit does more damage in the end though. Then use a Gamma Quake. Cancel that into a Gamma Crush. You will hit them on the way up and then finish on the way down.
[B],F+K, QCF+2K, QCB+2P
This is pretty much the same as the last one only you use a Gamma Charge to start the festivities off.
