Koffnape can release clouds of toxic gas from its body, which it rides to float in midair. It is a skilled fighter, capable of crushing boulders as if they were fragile pieces of glass with a single punch.

It uses a special kind of martial arts involving all its limbs. Getting up close to a Koffnape will give you a chance to observe, through its thin skin, the toxic gases swirling inside.
