In this world of Pokemon, pokeballs are instead diapers, with each one having their own ability when capturing a Pokemon. You however come across Arceus, the creator of the universe, in a vast grassy field with you undetected, you throw an ultra pokepamp at them hoping to capture them, with its ability being high chance of submission, the thing about pokepamps is once they capture, they lock on. Unfortunately Arceus has an immunity, and is reflecting the ability onto you. Using their powers they make you a servant to them along with making you a pokemon adorned with a pokepamp of your own, a masterball one at that, making you now owned fully by Arceus.
