I’m currently working on a project where you can have Pokémon battles against trainers from across the multiverse. If there’s a character you would like to see in it, either original or licensed, by all means, nominate them in the comments!
Also, if it’s an original character, please include a link to a ref, and some ideas for what Pokémon they would train, with their nomination.
With any luck, I’ll have version 1.0 ready in a year, maybe less!
