Duorogue's gelatinous body can resist a lot of physical damage, so it can train roughly and vigorously for hours without much wear and tear. Over time it will adjust its body's shape to better fit its specialized type of fighting.

Duorogue become stressed out if they do not get to train every day. When their brains, now divided in two, are thinking the same thoughts, these Pokémon exhibit their maximum power.
