Have you played a Hulk online? A decent one? His smash attack thing that hits downward has super armor, once that hits, he can launch you into a 3 to 4 hit air combo into earthquake special. That's about 50% health on Zero. If I don't switch out, chances are I'll die if he does that combo once more.
I bring in Amaterasu, I try to attack, SMASH! launch 4 hit combo special blam!! Half health gone on the dog now! If I brought in an assist than more than half half gone from him.
Aight I got this, so I attack, blam boo bahhh!! 25 hit combo!! Less than 50% health gone from Hulk?? WTF!!
Seriously, you haven't fought a good Hulk yet if you can't see why I'm complaining. They're getting more common online daily.
I will say that one of the reasons I have a problem with him is that I can't do a special after I combo with Zero. Working on that. Also if I camp I might have better outcomes but F camping.
