Lei Bo

Lei Bo (onyomi: Rai Haku) is one of Yuan Shu's officers. However, when Yuan Shu became pompous and gluttonous after receiving the Imperial Seal, Lei Bo left him with Chen Lan to become a Song Shan bandit.

Historical Information
Not much is written about Lei Bo. He originated from Yangzhou and served under Yuan Shu. However, he banded together with Chan Lan after his lord's defeat and headed for Mount Qian. In 199, Yuan Shu asked to take shelter at their place but was denied. According to some stories, Lei Bo later regretted the decision and tried to rendezvous with Yuan Shu. However, he lost track of his supplies and starved to death.

It's currently unknown if his name actually was or if he was related to Lei Xu (雷緒). Lei Xu shared a similar background as Lei Bo and was said to have took part in Chan Lan's rebellion in 200. After Mount Qian was suppressed, he was acquitted thanks to Liu Fu's intervention and served Wei. To assist with the struggles in Lujiang, he was assigned under Xiahou Yuan's command. Some time after receiving his new post, however, he lead thousands of troops across four counties to join Liu Bei. He has no further records and wasn't a figure who was adapted for the novel.

Romance of the Three Kingdoms
His role in the Romance of the Three Kingdoms is somewhat similar to his historical counterpart. He served Yuan Shu as one of his generals and was a general under Ji Ling. He later fought Zhang Liao and Zang Ba at Langye. Through a report conducted by scouts, the reader learns that Chen Lan and Lei Bo became disgusted by Yuan Shu's arrogance and fled to their mountain fortress, Mount Song. Their departure greatly reduced Yuan Shu's strength. In chapter 21, he and Chan Lan appeared when Liu Bei's army closes in on the remnants of Yuan Shu's forces. The two generals barred the road to Shouchun and forced Yuan Shu to seek refuge elsewhere. They are not mentioned again in the novel.
