Trooma was a member of Team Stylish.
Trooma was one of Dr. Stylish's strongest henchmen. It is unknown whether he had Dr. Stylish perform experiments on him or not. He was the first to execute the attack on Night Raid by submerging himself inside the pool, and attacked Leone by throwing a knife. Leone then kills Trooma in a single blow when he attempted to ambush Mine from behind.
