Varro stands out from the other gladiators with his short, blond curly hair. He has a friendly demeanor and open face, giving him a boyish look. Even from before training in the ludus, Varro boasts a muscular build.
Varro is one of the kinder and friendlier of the gladiators. He is a gladiator by his own choice, deciding that he would pay off his gambling debts by fighting in the arena and putting his winnings towards the debt; these are also sent off to support his wife, Aurelia, and son. He chose to pay off the debt out of honor instead of taking the coward's route, which would have been to flee Capua and hide.
Despite his more gentle nature, Varro is boisterous and enjoys sparring with Spartacus, with whom he has a close friendship. In the arena he is a strong, agile fighter and a worthy opponent.
Spartacus and Varro are brought into Batiatus ludus in the same group. During their first day of training, the two spark a conversation over lunch and Varro believes he is in good company with Spartacus. The next day, when they receive no food, Spartacus shares the bread Ashur gave him with Varro.
Varro reveals to Spartacus that he had submitted himself to Batiatus in order to pay off debts he had previously incurred, with his primary interest being to support his family. He becomes skilled as a gladiator, and often partakes in wagers. He stands by Spartacus, no matter how badly the latter is treated. On the day his wife, Aurelia, comes to visit him with their son, she tells him she is with child by a man named Titus who provided a home for her while Varro was gone. Varro feels betrayed, and is not swayed when Aurelia tries to tell him she was raped. He then refuses to support her with his earnings, at one point even spending them on having sex with a slave girl. Spartacus, recently widowed, convinces his friend to forgive his wife by winning money from him and then giving it back. After days of waiting, Aurelia reaches Varro again, and he tells her that he will support her and her unborn child. His spirits are renewed once more.
That same night, Spartacus is requested by Numerius to perform in an exhibition match at his birthday party. It is originally intended for Spartacus to face Crixus, but when Numerius is seduced by Ilithyia, who wishes to cause Spartacus anguish, it is decided that he must face Varro instead. The two duel at the festivities in front of a group of high standing citizens as well as Numerius and his father, Calavius. They appear to be evenly matched, with Varro even landing a hit on Spartacus and inflicting a small wound, but is eventually bested by Spartacus and falls to his knees in a joking fashion. Spartacus, his sword to Varro's neck, then looks to Numerius to pass "judgement" on Varro. To his and everyone else's surprise, Numerius gives Varro the thumbs down, meaning Spartacus must kill him. Spartacus, in a deep state of inner turmoil, looks to Batiatus for guidance, who then attempts to interject by stating to Calavius that the fight was simply for exhibition and not to the death. Calavius, however, admires his son's blood-thirstiness and tells Batiatus to see his wish carried out. Batiatus, who wishes to please Calavius in order to further his ambitions, gestures to Spartacus to finish Varro. Spartacus does not move, and guards prepare to advance on the two. Varro pleads with Spartacus to do it so that they both are not killed. He pulls Spartacus' sword into himself, and asks him to live and see his family provided for, as he would have done the same for his friend. Spartacus, not wishing to see his friend suffer, drives the blade home, killing him. The next day, Varro's body is taken out of the ludus on a wagon by a heartbroken Aurelia and her son.
