Though Nathan has a Pokéball for Emolga, it generally likes to stay outside its Pokéball and either fly beside Nathan, or remain on his shoulder. It is also noted to be rather spunky and enjoys battling.
Emolga is a rodent-like Pokémon, primarily white in coloration, that most resembles a flying squirrel. It possesses black eyes, a tiny nose, and yellow cheek patches. Its ears, positioned at the top of its head, are rounded in shape and black in coloration, with yellow and white sections of coloration in the inside of its ears. Emolga sports a vaguely hood-like patterning of black around its head, with a spiky extension of the pattern above its face. Emolga possesses winglike, yellow-colored flaps connected to its three-fingered arms. Its feet are white-colored and fairly small and its black-colored tail is in a jagged shape.
