Late Han warlord, the unbeatable fighter of 三国演义 on his horse 赤兔 (Red Hare), who killed two masters, Ding Yuan and Dong Zhuo. Cao Cao captured and executed him.
In 三国演义, 张飞 taunts him as a 三姓家奴, 'slave of three surnames': the novel makes him the adopted son first of 丁原, then of 董卓, on top of his own surname 吕.

The novel's 三英战吕布, 'the three heroes fight Lü Bu', has 刘备, 关羽 and 张飞 take him on together without beating him. The phrase is still borrowed for any three-against-one contest.
