MCU Thor trying to kills Thanos again in the beginning of Endgame scene.

Thanos was half dead already, so he still can with Mjolnir.

5 average hits may not be enough to kill Thanos but will hurt him badly for sure.

If these are strongest lighting-charged hits, then he can kill Thanos.

He smashes Thanos' skull in.

Yes

Definitely not. Thanos tanked a Marvel bullrush and tanked a Hulkbuster punch. The most he could do is bruise his face but he's not killing him with 5 hits. That's insane.

@elsebbe:

This is not a fight thread.

The adrenaline must've been off charts in that scene, so with some serious head smashes he could conceivably do it.

If he uses Sokovia level blows than yes.

Perhaps but all things considered he was crippled and weak he still tanked Carol, Hulk Buster and was fine after some pain from his arm being chopped off lol.

Yes. He was really pissed. Every smash would have been massive.

Thanos wouldnt go down from 5 hits

Fat Thor? doubt it.

Then why is it in battles and not general discussion?
