Volcano is a tall man with a very muscular physique, and orange, stylized hair. He wears a baggy, navy blue bodysuit, and very bulky, rock-like boots, gauntlets, and shoulders, with various protrusions and holes coming out of them. He also wears a gas mask strapped to his shoulder pads, and an orange belt.
Not much is known about his personality.
- Volcannon (ヴォルカノン Vorukanon?): By hitting the ground with his right arm, Maguma concentrates a large amount of lava to shoot in multiple directions.
Shoulder Pads and Gauntlets: The devices on his hands and shoulders allow him to launch his fire farther, and the shoulder pores seem to help him regulate body temperature.
Mask: Located in the middle of his mask is a mercury thermometer for an unknown purpose. (Most likely also for the purpose of regulating body temperature.)
- Maguma is similar to Endeavor in appearance, with both characters wearing a blue suit, large boots and gauntlets. Both characters also have a Quirk revolving around fiery substances.
