Greetings people of PRO! I made a list of baton passers for bosses to help new players or planning to build a team for end-game bosses. I separated the physical baton passers and special attack for their respective sweepers.
NOTE: Some moves can be learnt by leveling, TM, and Egg move. And if I didn't mention other Pokemons that means I forgot. Please leave a comment of ones I didn't mention and I'll edit it out. Thank you!
