Herolune is a tall bipedal canine Pokémon resembling a dog or wolf. Its body is primarily covered by spiky brown fur, which forms a long mane on its head. The fur on its tail and mane is tipped with a darker shade of brown. Its paws are colored red and resemble boots and gloves. It has white eyes shadowed with black patches, a yellow cape, and its face and chest are covered with yellow patches which resemble a mask and breastplate. The latter also has a red crescent moon symbol in the middle. Four sharp white teeth can be seen protruding from its upper jaw. Male Herolune has a muscular build, whereas the female has a pair of small black eyelashes on each eye and a slimmer build, with smaller paws, a more slender torso and a shorter mane.
