Sully Southland - a typical 25 year old growing up in the US. After losing her job at the Library, she is hired at the Museum of Natural History as a maintenance worker. One night after hours as she's cleaning she bumps into the gladiator exhibit, knocking the statues over. In the process of standing them back up she trips over the props and knocks herself unconscious on a nearby bolder. Awakening she finds herself in Capua 73 bc. Struggling to find a way back to her time, she is caught up in the schemes and deception of the House Batiatus. She is described as having a tan complexion, soft muscular body, with strikingly light blue eyes, full brows and lips, and deep brown dreadlocks reaching past her waist. (Looks like Evolet from 10,000 BC)

Spartacus - (real name unknown) is a Thracian warrior who became a famous Gladiator in the Arena, later to build a legend upon himself during the Third Servile War, he served as a gladiator in Batiatus' Ludus under the direction of Doctore and rivaled the then-Champion of Capua, Crixus.

Varro - a gladiator in Batiatus' Ludus, 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.

Crixus - is one of the top gladiators in Batiatus' Ludus, and later becomes a trusted ally to Spartacus. Formerly the Champion of Capua, he is known as the Undefeated Gaul. Crixus is a hardy, muscled man with skin bearing the toils of past battles. When he first arrived at the Ludus, he resembled Spartacus (as a Thracian warrior before being captured) with long, black hair and a thick beard. He is short in comparison to some of the other gladiators, but equal in skill, courage and strength. As time passed, he cut his hair down to a buzzed look (with a scar seen the right side of his cranium) and typically wears shoulder padding unique to his character. He usually wears a serious expression, which only softens to a smile around Naevia.

Quintus Lentulus Batiatus - is a Lanista, a trainer and trader of gladiators. He is head of his family's ludus (gladiator training school) in Capua and Dominus (master) to Spartacus. Batiatus is a middle aged man of small stature and girth. He is already beginning to show his age in his wrinkles. He can appear both friendly and menacing, depending on his mood. Batiatus' demeanor can change very easily. The conflict between the love Batiatus feels for his wife and the need to impress his father, is a key motivator in Batiatus' life, driving him to extreme actions in the course of the drama.

Lucretia - is a woman of moderate standing in the land of Capua and lives with her husband, Batiatus, in the villa above his ludus. Through her husband's (and to an extent her own) schemes, the couple manage to climb quite high on the social scale. Lucretia's natural hair is cropped short, but she wears a long, curly wig of either crimson red or platinum blonde. She is tall, around the same height as her 5'10" husband, and has blue eyes. Despite her husband's inconsistent financial state, she likes to wear expensive gowns and jewellery, perhaps in an effort to compete with Ilithyia.

Oenomaus - was the gladiator trainer in Batiatus' Ludus, and was traditionally referred to only by the title of Doctore. He was married to Melitta before her death. Oenomaus is a tall man who has dark skin and no hair. He is almost always seen wearing the Doctore armour, which hides three large scars he received from his fight with Theokoles. Another scar cuts across the left side of his face.

Ilithyia - is a wealthy Roman woman, daughter of Senator Albinius, and married to Praetor Claudius Glaber. Ilithyia has long, wavy blonde hair and blue eyes and is of average height. Due to her father's wealth she is always seen wearing lavish dresses and extravagant jewelry, whatever is fashionable amongst the higher levels of Roman society. lithyia is married to Claudius Glaber and shares many of his deceitful traits. She is a coquette and devious young woman underneath her more innocent appearance, individual and manipulative without aid of her husband. She along with him shares a strong dislike for Spartacus and longs to see him dead. In contradiction, she is highly fascinated by the other gladiators, in particular Crixus. She admires their strength and ferocity in battle, and after a suggestion from Lucretia, buys one of her own. She hopes to make some of her friends in high roman circles jealous of this purchase, but is seen to still be the one trying to amuse them and gain their approval.

Ashur - is an ex-gladiator in Batiatus' ludus. Due to a conflict with Crixus he was crippled and forced to wear a brace on his right leg. Since then, he became Batiatus' errand boy, accompanying him into the city to aid in transactions or sometimes going alone for more private business. Using his years in the ludus, Ashur seeks to become a link between Spartacus and the Romans who are hunting him. Ashur has a tan complexion and brown eyes, with dark hair cut. As a gladiator, he kept his head nearly bald and sported a beard with one braid. After his fall, he alters his appearance, sporting a very short and a close-shaven mustache, beard, and goatee. He has a muscular build, though he has lost the tone that he once sported as a gladiator. He bears a scar on his forehead and larger burn scar from his left shoulder to his bicep. At one point he bears the mark of the brotherhood of the House of Batiatus on his right forearm.

Barca - was one of several gladiators in Batiatus' Ludus. He is also known as the Beast of Carthage. Barca has light-brown skin tone and is the tallest gladiator in the ludus. He has long, shoulder-length black hair, which he wears behind him in dreadlocks and allows it to fall on his shoulders. He usually wears a dark-colored light vest, which covers his right side and comes down diagonally from the left shoulder, in addition to his subligaria. Barca fights in the style of hoplomachus, and is equipped in the arena accordingly with a spear, round shield and short sword.

Theokoles - was a legendary Greek gladiator and was also known as the Shadow of Death. Theokoles is a huge Greek (Spartan) albino gladiator with deathly pale skin and reddish eyes. His skin is covered with scars; in particular his face, across which there are two deep gashes. He has a tattoo on one shoulder, which was given to him by a band of pirates he served with for a time. Theokoles' albinism accounts for his pale skin, red eyes and photophobia. He fights wearing very little armor and wields two great swords
