Clare plays Gannicus in the show and told Collider that his character is a "pretty self-destructive gladiator".
"Gannicus has an extreme amount of skill, but he's very self-destructive and he's always trying to escape his reality," he said. "He was an interesting character who we really get to unpick through the six episodes. We have a great through-line and a great opportunity to see this man rise within everything that keeps him down."
Clare also suggested that he wasn't nervous about joining an established cast.
"Being the new guy's always great," he said. "You get to go in fresh with your choices and you get to bring new life and breath and a new energy into something that's already established."
Spartacus: Gods of the Arena continues on Fridays at 10pm on Starz.
