Biology
Latios is a Pokémon with a birdlike body stylized after a plane. Its body flows slowly into a thick neck, giving it a bulky appearance. It has no legs, usually floating instead. Most of its body is blue, with white areas near its arms and a white stripe on its back that extend up to its head. Jet-plane wings sit on top of its back, while two tall, jagged fins point behind it from its rear. A red triangle marks the center of its chest, while a blue mask partially covers its face. Long, ear-like fins extend from its jaws to over its head, and its eyes are red. It has three-fingered arms with a blue covering on the outer side of the lower arms. Latios is a male-only species, with Latias being its female counterpart.
