Mc will be izuku(i don't know if i will make him a reincarnator or not), and he will awaken his quirk at age 4, he will dream of the first ark island(he will respawn in the arks, but he won't test that in the real world) and will wake up after 8 hours and then notice he still has the arm implant from his dream and his levels and engrams, mc will go to ark every night but will not be able to bring items with him, he will ascend into ark:scorched earth, ark: aberrations, etc eventualy. Mc will be done with his ark journey by the time canon rolls arround, and would have worked on rebuilding his stuff on the real work(mc would save his alowence to buy resources to build trinkets to sell for a profit to buy more resources so he can finaly get his gear) and spent most of recent years into studing a way to sintetize the element substance from ark in the real world(momo will be his solution once he meets her at ua). Once mc gets his hands on element, he will not only upgrade all his stuff to tek, but will also start on geneticaly replicating his tames(all contained into cryopods untill needed)
