Sonic, Freedom planet,dragon ball and RWBY all characters: Trunks: I don’t know who that is. But no, you couldn’t. I mean, you could, but it wouldn’t be the same you. You see, when I travel back to the past, I’m technically going to a different universe…

“Does he mean…” Eggman wonders.

Gohan: Oh, you mean multiverse theory?

Trunks: Wait, what? “What?” Everyone, minus a few, question. Unaware of such a theory.

Gohan: Yeah. (cuts to a chalkboard and it shows what Gohan is explaining) With every decision, it creates a branch in the timeline. Whenever you travel back in time, you’re actually entering another parallel universe Each universe could have different events and outcomes, even if they started similarly. So, technically, if you were to travel back and change something, it wouldn’t affect your current universe, but rather create a new one with the changes you made.
