Lopunny

Mega Lopunny has an excellent base 135 Speed, outpacing the majority of the unboosted metagame. It also has an impressive base 136 Attack, being able to deal a lot of damage to Pokemon that don't resist its STAB moves. Together, the high Attack and Speed stats of Mega Lopunny make it an excellent cleaner. Mega Lopunny's Fighting-type STAB moves allow it to hit Dark-, Ice-, Normal-, Rock-, and Steel-types super effectively. Thanks to its STAB combination, Mega Lopunny can hit every type within the metagame for at least neutral damage. With Scrappy, Mega Lopunny is also able to hit Ghost-types such as Sableye, Gengar, and Doublade. In conjunction with Fake Out, this guarantees that Lopunny can safely Mega Evolve. Mega Lopunny can also switch into a predicted Knock Off from users such as Bisharp and Weavile, which helps item-reliant Pokemon such as Chansey and Porygon2. However, Mega Lopunny's bulk is pretty average for an offensive Pokemon, and its Normal / Fighting typing makes it weak to common types such as Fairy, Fighting, and Psychic. Mega Lopunny is also easily worn down by entry hazards, such as Spikes and Stealth Rock, and status effects, such as burn and poison. Due to its lack of power, Mega Lopunny has trouble breaking through physical walls such as Slowbro, Skarmory, and Hippowdon.
