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.
Similarly, no other Pokémon have the same Egg Group combination as Ferrothorn and its pre-evolved form.
Ferrothorn and its pre-evolution have the fewest weaknesses of all Grass-type Pokémon.
Ferrothorn has the highest Defense base stat of all Grass-type Pokémon, and the highest Special Defense base stat of all non-legendary Grass-type Pokémon.
Ferrothorn is the only Pokémon with a base stat total of 489.
Ferrothorn and Escavalier are tied for being the slowest fully evolved Pokémon that are part of an evolutionary line, having a base Speed stat of 20.
It appears to be based on durian plants. Its vines resemble military flails. The vines also resemble a fully-grown brier plant, just as its unevolved form resembles a seed. It could also be based on the tribulus, which is a species of thorny plants whose name, during Roman times, also meant caltrops, which is a thorny metallic weapon used to puncture the feet of invading soldiers. Also, the "tri-" in tribulus means "three", which is also the same number of pods Ferrothorn has.
Name origin
Ferrothorn is a combination of ferrum (Latin for iron) and thorn (a protective spine found on many plants).
Nutrey may be a combination of nut and rey (Spanish for king), 鈴 rei (bell), or trey (Italian for three anglicized, referring to its three appendages).
