Pokemon: I'm a Super Hisuian

【Pokemon + adventure + everyday life + main storyline + a slow burn + brute strength works wonders】 My name is Luo Xiao. After meeting every Pokemon and obtaining a fragment of Arceus, I borrowed the power of the Great Sinnoh Deity to send myself back to the future. Only... this future doesn't seem to be the one I came from... When a rookie Trainer can't catch a Pokemon with a Poké Ball, Luo Xiao hands them a Heavy Ball: “Try this one. It works great.” When Pokemon go berserk for unknown reasons, Luo Xiao charges straight in with his Hisuian companions and a bag full of Ultra Balls. When the three Sinnoh troublemakers encounter the young man again, they remember the terror of being ruled by the Super Hisuian all those years ago.
