Rebecca

Rebecca is a gladiator in Block D at the Corrida Colosseum.

Appearance
She is slightly taller than Luffy with long braided hair.

She wears a revealing scale armor bikini, with a dark paludamentum, as well as a ridge helmet, and a pair of greaves and gloves. She carries a large sword and shield.

Personality
Rebecca is a calm and prideful warrior that harbors a deep resentment towards Doflamingo and wishes to gain the Mera Mera no Mi to kill him.

She also appears to have an appreciation for folklore or just the history of the Corrida Colosseum, as she enlightened Lucy (Luffy) upon noticing his interest in the giant statue of Kyros.

Abilities and Powers
As she wants to eat the Mera Mera no Mi, it indicates that she is not a Devil Fruit user. However, according to some of the other fighters, she is the "Undefeated Woman", implying that she has never lost a fight yet, but at the same time, it is suggested that she was bullied by Spartan.

Weapons
Rebecca wields a long medieval-esque sword, which from the ground up is almost as tall as her shoulders. She also has a rounded shield, which she carries on her left arm.

Dressrosa Arc
Rebecca entered the Corrida Colosseum tournament and was placed in block D. While in the waiting area, she met Luffy, posing as Lucy. Upon noticing his admiration of the statue of Kyros, she told him about his legendary status. After telling Luffy about the statue, two other fighters began teasing her about how she must be happy that Spartan was already eliminated. When Luffy asked what they meant, Rebecca told him not to mind them, though she was noticeably bothered by what they said.

After this, she declared that she will win the Mera Mera no Mi and defeat Doflamingo. She then asked Luffy what block he was assigned to and was happy to learn they are in different blocks. As she walked off, she told Luffy that it would be nice if they both survived the first round.
