Gannicus is a central character and anti-hero in Spartacus. He serves as champion in Batiatus' Ludus throughout the events of the prequel, Gods of the Arena, until his departure upon earning his freedom in the aftermath of the Games of the New Arena. He later returns in Vengeance initially as an acquaintance to the rebels, criticizing their cause against the Roman Republic, though he ironically becomes a rebel himself for the sake of his closest friend, Oenomaus. He is often referred to by others
"There is an old saying that in the house of Batiatus, anything can happen".
