Medicham

Mega Medicham is one of the most feared wallbreakers in the metagame thanks to its solid Speed stat, offensive STAB combination, coverage options, and sky-high Attack stat backed by Pure Power. Its Speed stat enables it to outpace key Pokemon like Tapu Lele, Kyurem-B, and Landorus-T. Mega Medicham can also utilize two solid priority moves in Fake Out and Bullet Punch to become an effective revenge killer by wearing down and picking off faster Pokemon like Mega Alakazam, Tapu Koko, and Greninja as well as boosted sweepers like Mega Charizard X, Gyarados, and Dragonite. However, Mega Medicham is held back by its frailty, forcing it to rely on smart sacrifices, pivot support, and aggressive switches to come in safely. It also struggles against bulky Psychic-types like Slowbro, Cresselia, and Reuniclus and is outpaced and revenge killed by faster Pokemon like Mega Alakazam, Greninja, and Tornadus-T. Additionally, all of Mega Medicham's attacking options force it to make contact to deal damage, leaving it vulnerable to contact punishers like Garchomp and Rocky Helmet users like Tornadus-T and Zapdos.
