呂布
Li Su, an official under Dong Zhuo who is from the same commandery as Lü Bu, then volunteers to persuade Lü Bu to defect to Dong Zhuo's side. Bringing along a famous steed named Red Hare and other luscious gifts, he meets Lü Bu at his camp outside the city. Attracted by the gifts and feeling convinced by Li Su, Lü Bu agrees to betray his foster father and defect to Dong Zhuo's side. That very night, Lü Bu barges into Ding Yuan's tent, decapitates him and brings his head as a present to Dong Zhuo the following day.
