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 willingly 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.
Equipment and Skills
He was seen to carry knives around with him, which he used to launch attacks, usually by surprise. He seems to be very agile and quite adept in performing assassinations; even Leone was caught by surprise. His skills earned him the position of a knight in Dr. Stylish's team.
