He is also rather prideful, seemingly surrounding himself with lesser monsters.

At the Monster Association base, he explains to a fellow member how he became a monster by grooming his hair, giving it magical properties.

Later, Devil Long Hair shows up against Atomic Samurai's three disciples, Iaian, Bushidrill and Okamaitachi. Despite injuring Okamaitachi, he was still defeated by the trio when they worked together to cut off all his hair.

Hair Manipulation: Devil Long Hair can manipulate his hair to lengthen and move as he likes. They appear to be extremely durable as they were able to catch Okamaitachi's air blades and tunnel through solid ground to launch attacks from surprising directions.
