What do you do after you complete a Nuzlocke in Pokemon? [closed]
The Pokémon Nuzlocke challenge is a self-imposed challenge, meaning that there is no direction that the game outright forces you towards. After you reach your self-imposed goal you're free to play however you see fit. If you desire, you no longer have to adhere to the challenge's rules after defeating all gym leaders.
Because the Nuzlocke challenge is self-imposed there are no repercussions for breaking its rules.
