Goku vs Jiren and Belmod

Two vs one.

Who wins?

The only reason he lost to Jiren the first time, is because he hadn't perfected UI. Add Beerus praising him as "godly", and it's likely he's much stronger too.

And if Belmod is weaker then Jiren, I can't see how even two on one makes a difference. After all, UI automatically defends against any attack.. What are they gonna do, distract him while the other attacks? Goku would simply dodge the ambush.

Goku stomps, imo.

Current UI Goku >> UI Goku(ToP) > Jiren ~/> Belmond.

So he takes the team?

Yes.

Current UI Goku stomps Jiren easily. So if Jiren really is above Belmond, like most material suggests, Goku would stomp him even easier.

The only "?" for me is how Goku would do against a true Hakai from Belmond(assuming Belmond got the opportunity to deliver one.)
