Frankie Carbone (Gotham)

History
Frankie Carbone was Sal Maroni's right hand man. After assaulting one of Don Falcone's warehouses, he attempted to kill Oswald Cobblepot for his rapid rise on Maroni's ranks. However, Frankie didn't pay enough for his guys and once Oswald made a higher offer, they immediately sided with him and held him while The Peguin stabbed him.
