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. Although a brave warrior, she can be extremely emotional at times as shown when she did shed some tears as she saw Thunder Soldier. She is sociable and can be quick to engage in friendly conversations especially with those who are acquainted with Luffy.
