Arrabbiato Bagno was born Arrabbiato Flusso Toletta to Attivo Flusso and her husband Puzzo Toletta.

As a child Arrabbiato was often chastised and on many occasions was badly beaten by his abusive parents. Following the death of his parents due to alcoholism he was sent to live with his maternal uncle Rigoroso Flusso.

When first sent to live with his uncle Arrabbiato was a very withdrawn child and was incapable of forming bonds with others. In an attempt to draw Arrabbiato out of himself Rigoroso taght him the ways of the magical arts.

Arrabbiato was a quick learner and soon mastered simple tricks and illusions. Disappointed by the rate at which his uncle was teaching him, he confronted Rigoroso demanding to know more.

When Rigoroso informed him that he had taught all that he knew, Arrabbiato attacked and mortally wounded him. Filled with deep regret and sorrow Arrabbiato fled his home and set off to try find some way of resurrecting his slain uncle. In an attempt to hide his identity he changed his name to Bagno.
