Wagner Fiuza-Carrilho is a Brazilian born retired PE teacher and karate enthusiast now living in Pensnett, Dudley. Fiuza-Carrilho previously owned a martial arts and dance gym in Cradley Heath before becoming a P.E. teacher for a year at Leasowes Community College; he has also worked for a conservatory fitting company.

He said he entered the X Factor contest to get a "new start" and to be able to provide for his son. At the judges houses Fiuza-Carrilho performed "You Got The Love", to which Walsh joked to his assistant judge Sharon Osbourne that "He fancies you". Although he was not picked to be one the initial top 12 acts, mentor Walsh chose him as his wildcard for the live finals. Wagner moved out of The X Factor house after the second live show after complaining about his fellow contestants' behaviour.
