Hitmontop's main body has a spherical shape and is mostly blue (except for a brownish triangular patch on his chest). He has short legs with white bands at the lower portions, and big blue feet similar to Hitmonlee's (but with a different toe arrangement) and a circular brown marking on the underside. He has a skinny brownish tail that ends with a blue sphere with a spike on it. His head is round and brown with flat, curved extensions, a beady-eyed face and a single spike on top.
Hitmontop is a male-only species with no female-counterpart.
Hitmontop spins on his head and uses his tail and legs to smack enemies. Although Hitmontop travels faster spinning than walking, he is still capable of walking normally in which case he retracts his tail to its side.
They are urban species that would typically be found in urban areas.
