His hero costume consists of a black one-piece suit with a high collar, over which he wears various pieces of armor, all in a pale silver in color, including a chest plate, a metal collar around his neck and another around his upper arm, and metal vambraces that extend past his elbows pointed at the ends. Because of his Quirk, he possesses calves that are incredibly thick, and shaped like automobile engines, with six silver exhaust pipes protruding from each leg in columns of three. He usually wears a serious expression, and his eyebrows seem to be permanently pointed inwards, quite thin and long in length, the far ends sharply hooked inwards, and he wears glasses with rectangular lenses.
He has short dark blue hair, flattened neatly down and parted on the right side of his head, a small patch completely shaved near the base of his head, and rather square eyes which match the notably pointed shape of his jaw.
Tenya is a relatively tall and muscular young man with a wide frame.
