Taiyan had dark skin, light pink hair, and pointed ears. As she was created from a motorcycle, she had a headlight on her left breast and a tire fused into the lower half of her body. She could also take the form of a tire, giving her increased mobility and speed. Taiyan had the power to make an extra duplicate of herself with a maneuver called "Double Taiyan," and with "Chain Ring" could shoot a pair of golden rings with her replica that would act as handcuffs on opponents struck by them.
Kaolinite took advantage of Sailor Moon and Sailor Uranus' differences to tie them together with Taiyan's power. The Daimon and her double pursued the two Sailor Senshi to a cave, but once there lost sight of their prey. After the two Senshi learned to work together, they escaped from the handcuffs and as Sailor Uranus used World Shaking to destroy Taiyan's replica, Sailor Moon took the opportunity to finish the Daimon off with Moon Spiral Heart Attack.
- Her name is derived from the word "タイヤ" (pronounced "taiya"), which means "tire."
