The Green Elder

This is an Au where Izuku is a Brotherhood of steel Elder. His Chapter. The Alaskan Chapter With his Laser rifle and determination. He successfully was able to preserve all the technology in Alaska. One of the Tech backfires during testing and makes a portal to an alternate earth that hasn't been destroyed by the nukes. A world where China and Russia aren't fighting the US. A world Where Life isn't trying to kill them. Izuku grabs his power armor and takes a Team of Knights, Scribes and a paladin and enters the world. The Elder will find it weird when he finds a version of himself wanting to be a hero as the other is the same for his Elder counterpart.
