When most people think of gen 5 they think of "wow this sweeper hits so hard" and the "power creep". Ferrothorn is a Pokemon who goes completely against this track of thought and is the polar opposite. Black and White didn't introduce many good defensive threats but Ferrothorn is hands down the greatest defensive addition and arguably the best Pokemon defensively in the game. It has resistances coming out of its rear end, a fantastic ability which punishes physical sweepers, stellar defensive stats and typing and a movepool to match with things like Thunderwave and Spikes. It is one of the few Pokemon who single handedly massacres most rain dance teams and will not go down unless its met with fire or fighting moves, even then it will not go down without a fight. If you don't pack super effective moves for this thorny Pokemon, chances are Ferrothorn is going to outstall and set up on your whole team. Even if you do have super effective hits you will most likely be met with Ferrothorn's partner in crime, Jellicent to take said hits. Take special note to counter both Ferrothorn and the combo it forms with Jellicent when building a team.

This is THE set for Ferrothorn and the best thing it does. Anything ranging from DD Kingdra to Suicune and even Metagross and Haxorus isnt getting past this defensive behemoth. It can also choose to take hits from either side of the spectrum with ease additionally. The way it plays is rather simple, switch in on one of the many, many things that cannot hurt it, set up Spikes to punish switch ins, stall every things brains out with Leech Seed and counter many of the metagames top threats. Its no slouch offensively with its very good base 94 attack so Power Whip and especially Gyro Ball (due to base 20 speed) sting. Stealth Rock is an option though too when it cannot be added elsewhere on the team. Protect can be used to help stall and rack up Leech Seed damage whilst Thunderwave cripples sweepers.
Countering Ferrothorn isnt difficult really, what makes it deadly is the long list of which it can set up on. Rapid Spinners stop it doing its job which is to set up entry hazards. Forretress makes a decent counter as its one of the few things that can spin which doesn't fear it, though beware of Iron Barbs and Leech Seed as they will wear down Forry. Hitmontop can use Foresight to bypass spin blockers too and doesn't fear anything Ferrothorn can do and can also hit it with its fighting STAB. Bulky Grass types with Hidden Power Fire make good counters, like Celebi. Heatran and Magnezone are top of the list counters as they take near nothing from anything it does, the latter even traps it making it unable to escape. Conkeldurr and Machamp make it run for the hills as does any powerful fighting type such as Lucario, though Gyro Ball hurts the latter alot despite the resistance. Infernape is in a similar position too. Volcarona can use it as set up fodder as can Chandelure. Scizor makes a good counter too as it can U-Turn away from Leech Seeds and resists both of Ferrothorn's STAB movies and can either Swords Dance or just hit it with a CB SuperPower. Xatu and Espeon get a special mention as they turn all spiking efforts against you with their ability Magic Bounce and both immune to Leech Seed. Espeon is frailer so cant take hits but if it gets in it can maim Ferrothorn with Hidden Power Fire. Xatu can do the same but isnt as frail and can Roost and set up Reflect to make Ferrothorn useless against it.
