Bruno had short black hair, Mediterranean-esque features, trimmed hair on his chin and a trimmed stache. He styles his Paulkee Guild uniform with a camo military style jacket, black singlet, black pants and black boots.
Bruno initially showed himself to be one of the most talkative and perhaps most empathetic of the Paulklee Guild Mercenaries sent to intercept the Second Destroyers as he himself voice his opposition and dislike to having to fight against the Hunters once he saw that they were only a bunch of children and felt somewhat discouraged to having to fight them, due to being reminded of his own daughter when looking at them.But he non the less felt no other feelings as he was forced to defend himself against Maverick.
Bruno out of all the Twilight combatants that fought against the Second Destroyers was the only one to show any kind of mercy to them, with he himself felt a strong sense of disgust at at having to use lethal force against her and inwardly thought badly on who raised them into becoming hunters while expressing his disappointment and pity for the hunter and later during their battle attempted numerous times to discourage her from fighting further against him and attempted to give her numerous chances to save herself anymore pain by cooperating with him. However Bruno eventually began to harbor severe hatred for Maverick due to her killing Sandra and sadistically taking pleasure in mocking him for her death,With Bruno himself attempting to get revenge by killing one of Mavericks's comrades.
Later upon his last moments before being killed by Maverick, Bruno shows a softer side to himself as he later reveals that he himself possess a daughter of his own and attempted to comfort Connie after losing her parents.
Bruno was a high-level Twilight capable of matching and at one point overwhelming a combatant as dangerous as Maverick.
He wielded a black kanabō and was quite proficient in using it one handed, considering it is typically a heavy weapon.
