This seems like a good and original idea, I have a quick suggestion about this little game.
Why not put an ak head shot challenge/attack, one player has to shoot the other player with a headshot to do damage while the other player tries to avoid it by moving only left or right. If the player that has to shoot doesn’t in under 20 - 30 seconds or so then the attack automatically fails.
I feel like you should also add some other effects admins can do like make the other “Pokémon” slowdown or make a weak attack or something like that.
