Slowbro

While Slowbro seems like an odd choice for the OU tier, it can be handy for checking some of the metagame's top threats. When using Slowbro in OU, make sure that it isn't being used in a role where it can be outclassed by Suicune and Vaporeon. Slowbro is a blessing on teams that struggle with Dragon Dance sweepers (excluding Tyranitar), and will see the most use on those teams. With its rock-solid Defense and decent Special Defense, however, it can be used as either a physical wall or a mixed wall. Slowbro does greatly struggle with Scizor, however; Scizor can easily switch in on Slowbro's relatively weak Surf and spam a STAB U-turn. Tyranitar can also be a huge problem for Slowbro, as it can deal hefty damage to it via Crunch. While Slowbro is quite bulky, it will fall to powerful special attacks. Gengar's Shadow Ball and Rotom-A's STAB attacks will deal a hefty hit to Slowbro. Don't let these negative factors discourage you, however, as Slowbro can be a huge asset to a team when used correctly.
