Arena is one of the main characters in Gladiator Academy.
Arena is strong, agile and bright. She's a key part of the team, but she is very reckless.
Arena has fair skin and long red hair. She wears a yellow headband, a brass bra, a short yellow skirt held up by a maroon belt, a brass pad on her right shoulder, and brown open-toed boots. When she does flips, it's shown she has off-white underwear.
- The evil Cadius has a crush on her, much to her dismay.
