Katsuki bakugou (parallel worlds)

Katsuki and his classmates in Class 1-A at U.A. High School were informed of something very surprising. Every teacher at U.A. had to inform their students of something, and it was this:

There are parallel worlds, and each parallel world has multiple dimensions, and each dimension has multiple universes. The parallel world they're in is called, not Bakugo, but rather, My Hero Academia, and there are other parallel worlds as well. What happens is that the parallel world of My Hero Academia, the parallel world of Bakugo, will swap the villains with the villains from Dragon Ball.

At first, the villains in Dragon Ball were incredibly powerful, capable of destroying entire galaxies in the blink of an eye. They were indeed very strong, having fought multiple times and appearing almost unstoppable. And they could see their villains in the parallel world of Dragon Ball through a sphere. The villains in Bakugo's world were weak compared to the heroes of Dragon Ball.
