Mankey, though presumed to be partly named after humans, bears almost no resemblance to them. Mankey more resembles other various primates. It is a tailed, bipedal Pokémon with a round body covered in whitish, messy fur. Mankey's ears are triangular with brown insides, and its arms, two-toed feet, and its curved tail is tipped with brown coloration. Mankey has a nose similar to a pig’s snout.
Mankey specialize in physical fighting, but they can sometimes know elemental attacks (though they don't usually excel at them).
Mankey are very aggressive and short-tempered. Anyone that gets on its bad side (which is easily done), will receive a severe thrashing. When Mankey starts shaking and its nasal breathing turns rough, it is a sure sign that it is becoming angry. However, because it goes into a towering rage almost instantly, it is impossible for anyone to flee its wrath. Mankey lives in treetop colonies, and if one becomes enraged, the whole colony rampages for no reason. If Mankey loses sight of its colony, it becomes infuriated by its loneliness.
Mankey can be found in vibrant forests, in mountains, or in valleys with rivers running through them. They are most common in Kanto, but can also be found in Johto.
The preferred food appears to be bananas and chestnuts, although Mankey usually lack the dexterity to peel them. Mankey will get agitated and rage after attempting to peel a chestnut's spiky shell.
