Growlvoir are very active, athletic Pokémon who love to play with their companions and rarely with strangers. Loud, hourly howls from Growlvoir signal that they are actively guarding their territory and will not tolerate any trespassers.

It apparently does not feel the pull of gravity because it supports itself with psychic power. Its superb sense of smell ensures that this Pokémon won't forget any scent, no matter what.
