Additionally, they will engage in occasional banter or praise each other's moves during battle. It seems that both of these personalities co-exist in a friendship-like manner - this can be seen in Tira's inner dialogue in her Soulcalibur IV ending. Similar to how being damaged would affect Tira's moods in Soulcalibur III, Tira's two ' sides' can be changed either manually, or randomly, also altering her moveset. These alternate personalities manifest themselves in her battle style, as two stances: Jolly Side and Gloomy Side. In Soulcalibur IV, Tira develops two disparate personalities due to being exposed to Soul Calibur and Soul Edge's conflict, both representing the opposite spectrums of her erratic emotions. When Soulcalibur III was released, many fans speculated that Tira suffered from some form of bipolarity due to her interchangeable and unstable emotions. 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.
