She derives a demented form of amusement from others' suffering, apparently due to her upbringing as an assassin, and is lethally addicted to murdering others. Tira is nearly as ruthless and sadistic as her master, having no qualms with claiming the lives of her victims. In Soulcalibur V, Tira now has two, braided pigtails, which imitate the shape of a jester's hat, and her hair now possess three colors - white and two shades of purple. However, the real reason was to reflect her new, unstable personality, as revealed in an interview with one of the character designers of Soulcalibur IV. At first, this dramatic change was speculated to be the outcome of one of Tira's epilogues in her Tales of Souls Mode from Soulcalibur III, in which she was possessed by Soul Edge. She also has an unmarred body, and wears a red ensemble. In Soulcalibur IV, she undergoes a drastic evolution in design, exchanging her short blue hair for dark brown, lopsided pigtails with a long, thin braid on the back of her head. Early concept art shows Tira covered in scars on her face and body, but in the final illustration, they were replaced by painted purple stripes.
In her debut appearance, Tira has purple eyes, teal-colored hair, green rags, and feather-like fringes.
