Ferrothorn, The Thorn Pod Pokémon.
It fights by swinging around its three spiky feelers. A hit from these steel spikes can reduce a boulder to rubble.They attach themselves to cave ceilings, firing steel spikes at targets passing beneath them. By swinging around its three spiky feelers and shooting spikes, it can obliterate an opponent.
Overview
Ferrothorn was easily the best non-legendary Pokemon to come from Black & White. Havin stellar defenses, a good typing, an amazing movepool with moves like Stealth Rock, Spikes, Leech Seed, and so forth, making it one of the best support Pokemon in the entire game. Although weak to common Fighting and Fire moves, most of the time Ferrothorn is able to shrug them off, lay hazards, hurt the opponent with Iron Barbs, or cripple them. The only problems with Ferrothorn are its dismally low Speed, and no reliable recovery, but it makes up for these shortcomings by being the best defensive pivot in OU (if not the game).
