Frog Fangire

Frog Fangire: Using a sword & a rifle, the Frog Fangire can fire energy warts on his shoulders. In 1896, Bruce created the Black Star violin, attacking any he found not to have respect for his creation. He attacked Lillian Walker for that reason before being driven off by Garuru. Later, Bruce encounters Bram Stoker after he stole the Black Star from Lillian, with Bram's music soothing Bruce to see Bram as a worthy owner in spite of Bram turning him down. However, Bram has Bruce promise to not feed on humans again, helping him escape to start his life anew with the disposing of the Black Star as the first step.

In the present year, Bruce keeps a music player that plays Bram's music, a calming mechanism to keep him from breaking his promise. However, while taking a break, Bruce is driven into a frenzy after hearing a rock group & lashes on them before fighting Vampire King, the both exposing themselves to the other. After Scott saves him from William School, Bruce reveals what happened in the past. However, William refused to accept it, provoking Bruce into attacking people with Vampire King almost forced to kill him. Though Bruce regained his senses & ran off, he was found by William & mortally wounded by Cross' Cross Judgement. By the time Scott arrived, Bruce apologizes for breaking his word before he dies.
