Gravity vs Savage Hulk

Alright, Gravity punked the Rhino so badly. How would he do against the Savage Hulk?

He gets his ass handed to him by Hulk. Once Hulk took on Abomination and Rhino at the same time and they still couldn't beat him. What chance does Gravity stand against Hulk?

Graviton?

Who the shit is Gravity?

what happened with tittanus? did we find out who he was?
