The Hero that saved Remnant?

Class 1-A sees Deku for the first time since he's gone rouge. They are trying to talk him into going back to UA but it isn't working. They end up fighting Deku and win but as they are attempting to bring him back, they are attacked by a villain with a warpgate quirk. What they don't know is that this warpgate quirk doesn't allow people to travel from place to place, but it allows people to travel through dimensions. He doesn't know where he is, all he knows is that his goal is to stop AFO/Shigaraki. He isn't himself when he arrives and kills anything he deems dangerous. Then he learns that he is in a world called Remnant with no way back... Can Deku make his way back home or will he be stuck in this new world forever? MHA spoilers ahead!!!
