Scizor

Despite being an OU Pokemon, it is almost as if Scizor was designed for Uber play. Scizor is a superb scout for offensive teams with U-turn, which it gets STAB on. Scizor's STAB U-turns do a massive amount of damage to the many Psychic-type Pokemon in Ubers as well. Bullet Punch is a powerful priority move thanks to it being a STAB move boosted by Technician, meaning that Scizor is easily able to destroy Deoxys-A, and is also able to pick off weakened Pokemon such as Darkrai and Rayquaza. Scizor is one of the few viable users of Pursuit in Ubers, allowing Scizor to trap and kill Pokemon such as Mewtwo and Latias. To sweeten the deal, Scizor even pairs up well with Tickle Wobbuffet, allowing the duo to smash Blissey and Lugia to pieces. Scizor's excellent Bug / Steel typing allows it to take on the powerful Ice-type and Dragon-type attacks that are common in Ubers. Scizor even has access to Roost to take advantage of these great resistances. Overall, Scizor's amazing typing and wonderful movepool make it a force to be reckoned with in Ubers.
