While most trainers evolve Ferroseed into Ferrothorn immediately, the unevolved form has a niche with Eviolite boosting its defenses. Poison moves can't touch it, and only 2 types hit it super-effectively. Known as the Thorn Seed Pokemon.
Ferroseed's all-in on Defense at the expense of Speed. The physical lean is obvious from the bars. Yields 1 Defense EV and follows a medium-fast 1M XP curve.
When threatened, it attacks by shooting a barrage of spikes, which gives it a chance to escape by rolling away.
They stick their spikes into cave walls and absorb the minerals they find in the rock.
Ferroseed Weakness
ExcellentFire and Fighting-type moves hit Ferroseed for super-effective damage. Fire hits land at 4x, so they're the biggest threat. The upside? Poison-type moves can't touch it at all. 10 resistances give it solid defensive coverage on top of that. With 44 HP and balanced defenses, Ferroseed can afford to eat a neutral hit or two.
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)
Ferroseed evolves into Ferrothorn. It's a two-stage chain with the method shown below. Plenty of partners for breeding via two egg groups. Eggs are average hatch time. The evolved forms gain up to 184 total stats over Ferroseed.
How to Evolve
Breed Ferroseed easily with 57 breeding partners from the Plant and Mineral egg groups. Pass egg moves like Bullet Seed, Gravity, Leech Seed and 5 more to offspring.
Lead with Ferroseed, set Stealth Rock, and keep pressure on. Iron Barbs and Eviolite buy the time it needs, with HP-heavy investment EVs letting it take hits while controlling the hazard game.

Ferroseed isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Ferrothorn to unlock its full potential. At 305 BST, it's a stepping stone rather than a team anchor.
Watch for Blaziken (Fire) when using Ferroseed. They all hit it super-effectively with STAB. Blaziken is the most dangerous since Fire moves deal 4x damage. Fighting-type attackers are also a problem. Only 2 weaknesses means fewer dedicated counters to worry about. At base 10 Speed, Ferroseed won't outrun any of these threats so switching to a resist is usually the safer play.
Ferroseed evolves into Ferrothorn at level 40. Ferroseed is the base form of this evolutionary line.
Iron Barbs damages attacking Pokémon for 1/8 their max HP on contact — that's the one you want on Ferroseed. It's the only ability Ferroseed has.
Ferroseed fills the hazard setter role. It's a physical attacker with base 50 Attack. Base 10 Speed is low. Priority moves or Trick Room are the way to go. And it's enough bulk to take a hit or two.
Ferroseed appears in 7 games, including Black & White, Black 2 & White 2, and X & Y.
Introduced in Black & White, Ferroseed has appeared in 7 games across 5 generations. Later debuts mean fewer total appearances, but it's been a consistent presence since its introduction.
