Goku Black & Zamasu vs. Toppo & Dyspo

Who wins?

Toppo solos tbh. If he get distance between him, Zamasu and Black, he would rip Black arms off.

Team 1 fuses then stomps.

If they fuse, then yeah. Even if they rip Zamasu in half, they'd end up fighting an endless hoard.

Toppo godstomps.

Zamasu being immortal should seal the deal for team 1. But if fusion isn't allowed then it's probably going to be a very brutal win for Zamasu as he stays fighting until the others are tired out and he's strong enough to win....

Though IN theory Toppo should know Hakai because he's in training to be God of Destruction and could use that to end the fight easily.

Toppo kills Black and then proceeds at destroying Zamasu. Just that simple.

Without Hakai, he's going to have a hard time killing Zamasu though

It's a simple process. Kill Black and then rip Zamasu in half and toss each ends on different sides of earth. That is called ko.

Hahaha... Pre-fusion Black destroys Toppo. Dyspo is irrelevant.

If we go by the manga: Toppo ~ SSG Goku.

So yeah, as long as fusion is prohibited, Toppo solos.
