Hyde is a tall person with pale skin, razor-sharp teeth, and long lavender-white hair with bangs covering his right eye. And just like his older brother, Phi, he has heterochromia eyes; his right eye being red and his left eye green.

He wears a dark purple collar with silver studs, and a black gloved, bodysuit with dark-yellow lines on the torso, arm sleeves, and legs. The suit also sports violet plating on the arm sleeves, a violet full-connected pauldron, two violet rings around each upper arm and each shin, and a violet belt with a silver and red buckle, which has a purple base, and a white robe with violet borders. The robe is segmented into four flaps: the front one has purple markings on it, the left and right flaps have a silver plating with purple markings, and the last one is pure white. The suit also sports white hexagons with chartreuse borders: three on the pauldron, two on each forearm, and one on the left and right robe flap.
