Kimiko (Voiced by Grey DeLisle and by Jennifer Hale in the sequel) was one of the Xiaolin Monks and the Xiaolin Dragon of Fire. Along with the other warriors, she helped fight evil and collect Shen Gong Wu around the world. Her Wudai Weapon was the Arrow Sparrow. Her signature Wu was the Star Hanabi.
Kimiko was the daughter of Toshiro Tohomiko, the head of Tohomiko Electronics, a prominent Japanese video game company in Tokyo, Japan. As a result, she was able to get all the latest games and gadgets. However, as a young child she practically needed to beg her father to buy her clothes. She was extremely tech-savvy, as she had demonstrated on numerous occasions. She kept up with the wild fashion trends of Tokyo Street Style (Harajuku Style) and the latest e-gadgets so she could stay in touch with her friends and family. She used different clothes and hairstyles on a daily basis, but her signature hairstyle was her black hair, tied into two pigtails, along with light red or bright pink cheeks and red lips. Kimiko never went anywhere without her cell phone. Despite being a docile and rational person most of the time, befitting her element, Kimiko possessed a fiery temper. Often letting her pride and anger blur her better judgment, Kimiko sometimes took unnecessary risks to prove herself. Kimiko was a kind and sweet girl deep down; however, she got furious easily. She did not give up easily, either and was able to take some extreme attitudes when not controlled. She was also a good friend; however, she could sometimes control the boys of the group because she was the only girl. Kimiko has also shown to share a strong bond with her father. She possessed great skills in computer hacking, capable of hacking several computer systems.
