I am Rebecca[8] is the daughter of Scarlett and Kyros, the niece of Viola and the granddaughter of Riku Doldo III.[9] She is the former crown princess of Dressrosa,[10] who forfeited her title to live with her father[11] and currently serves as a lady-in-waiting to her aunt, Viola.[2]

While living under Donquixote Doflamingo's regime, she was imprisoned and forced to fight as a gladiator at the Corrida Colosseum. She joined a tournament to compete for the Mera Mera no Mi, winning the D Block and battling in the finals before Sabo claimed the Devil Fruit.[1] Rebecca is a fair-skinned and tall girl, but slightly shorter than Luffy. She has long, light pink hair, which she wears in a braid. She holds a strong resemblance to her mother.

As a gladiator, she wore a yellow scale armor bikini, with a turquoise paludamentum, as well as a ridge helmet, a pair of greaves and gloves, a high-heeled armor, and a necklace. The helmet got damaged during Hakuba's assault and was missing the visor's middle piece in the second round. It was completely shattered after Diamante bashed her over the head with a club. She carried a large sword and shield. She discarded the shield before entering the D Block battle royale.[4] She is considered extremely attractive and beautiful by the other gladiators.[3][12]

Underneath her helmet, her braid splits off into two strands starting at her temples. Rebecca is a calm and proud warrior who harbors a deep resentment towards Donquixote Doflamingo and wishes to obtain the Mera Mera no Mi to hunt him down and kill him. Furthermore, even though she pretends to shrug off others mocking her about Spartan, she is actually really bothered by it to the point of biting her bottom lip. She appears to have some knowledge of the Colosseum's history and was kind enough to enlighten Lucy upon noticing his interest in the giant statue of Kyros.[3] She is very respectful of others as she tried to get Ricky to heal up after his fight,[13] thanked Luffy for taking down Spartan,[3] and later paid for the food
