Mr. Mime @ Leftovers
Trait: Soundproof
EVs: 252 HP / 4 SDef / 252 Spd
Timid Nature (+Spd, -Atk)
- Calm Mind
- Substitute
- Psyshock
- Baton Pass
This boss is immune to Accelgor's Bug Buzz thanks to Soundproof and doesn't care about the rest of its moveset because of its fantastic special defense and Calm Mind. After a Calm Mind, Mr. Mime's Substitutes are never broken by Accelgor's strongest attack vs Mr. Mime, Giga Drain, so it can set up a Calm Mind, Substitute, and then Baton Pass them to an appropriate partner in an ideal scenario, though hopefully the opponent is smart enough to switch Accelgor out of Mr. Mime before it can set up too much. Mr. Mime itself is also pretty difficult to beat due to its ability to Baton Pass, which means that it's rather difficult to Pursuit if played well, and it should share great synergy with the next Pokemon on Team 2 because of its setup moves and Baton Pass.
