Ferrothorn

With Ferrothorn's excellent typing, defenses, and movepool, it can play a key role in any Ubers team. With its ten resistances and one immunity, it can switch into many common threats, such as Kyogre, Groudon, Palkia, and Zekrom, with ease. In conjunction with its support movepool, Ferrothorn's typing helps it to easily switch into a large number of threats and set up entry hazards such as Stealth Rock and Spikes, and annoy opponents with Leech Seed. Its reasonable base 94 Attack also allows it to deal respectable damage to certain offensive threats, such as Kyogre and Groudon. They take considerable damage from Power Whip, and many other sweepers, such as Mewtwo and Darkrai, fear Gyro Ball. Gyro Ball will almost always hit with maximum power thanks to Ferrothorn's minuscule base 20 Speed.
