| The Xiaolin Warriors' first and most annoying nemesis. Jack Spicer is notable for his robotic engineering, long rants, overuse of the word "evil" and his repetitive self-proclamation of "evil boy genius". He was responsible for releasing Wuya from the puzzle box that Grand Master Dashi locked her in, and aids her in finding Shen Gong Wu to conquer the world. Jack has aided the Xiaolin Warriors on occasion, and does show occasional leanings toward good. However, he always winds up back on the evil side. As a reflection of his character, his preferred Shen Gong Wu is the Monkey Staff, which was the only Shen Gong Wu he is left with at the end of the series. |
