GaryLocke

So if you've played through Kanto, you know how cheap Gary is. I may be wrong, but I'm pretty sure the team he has is different based on your starter choice. So in this two player Nuzlocke, you randomize the game, and decide who picks first. One person picks a starter, the other picks their starter based on if it has type advantage, the first trainers's first capture must have type advantage against the other's starter, and so on. So both basically play like Gary, trying to be cheap. After every rival battle, the two face off and whoever wins gets a little bonus. Any suggestions for extra rules/ the bonuses?

GaryLocke: You must give all of your Pokémon douche-y names, and any decisions you make must be rude, dickish, or douchey, unless you are FORCED to be nice to progress.

Also, you must beat every trainer you find in an area similar to Lavender Tower, and kill all Pokémon in the area. You are NOT allowed to catch the first Poke in these areas.

Bonuses could be the ability to catch another Pokémon on a route or being able to revive a Pokémon.
