Miraidon is a large robotic reptilian yet very humanoid Pokémon. Most of its body is violet in color, although its face, claws, abdomen, and tail are gray. Additionally, there are light purple accents on its shoulders and legs, the latter of which resemble jet engines when folded and allow it to float in the air. Its head has a dark purple casque, circular purple cheeks, two pairs of electric antennae, and black eyes. The eyes have a pixelated display; they usually show yellow-cyan pupils.
