What would happen to Superman if-?

Case 1- Someone intangible put their hand in his chest and go tangible?

Case 2- Beast boy enters in his head in his insect form and turn into T Rex?

Case 3- If he's hit with multiple Black Canary like cry?

Case 4- If he faces TK user. Can he over come it?

From what I know he has a force field surrounding his body making him insanely durable. Are those force field inside his body as well?

How many cases mentioned above he survives

1. Depends if there strong/durable. Mostly it would crush and sever the hand.

2. Beast boy dies fast. Even the inside of his head is very strong. See action comic 6

3. He's been around when moons and planets are getting blown up. A canary cry will have no effect.

4. Yes he fights captain comet in action comics 12.

@allstarsuperman What about Vision?

Actually Silver Banshee pretty easily hurt him in a Superman/Batman comics. He described it as multiple atomic bombs going inside his head. So, can it kill him?

In New 52?

Silver Banshee is magic.

@dernman: Has superman ever fought any sonic cry opponent except Banshee?

And what about other cases?

Case 1 it depends on the user.

If Martian Manhunter did it, it would hurt alot.
