Pokémon #598 in the National PokéDex, a dual type Grass/Steel Pokémon.
Ferrothorn is a Pokémon resembling a flattened durian. Its metallic body is covered in thorns, with three black stripes circling its width, the middle stripe having triangular decorations below the eyes of Ferrothorn. Its eyes have green rims, yellow scleras, and dark pupils. There is a green spike at the top of its body, and extending around it are vine-like, long green appendages tipped with spiky metal disks. It can use these appendages to either cling to ceilings of its cave or walk around. When hanging, it can attack its prey underneath by shooting spikes.
It evolves from Ferroseed.
