Elai
Elai (Chinese: 恶来, Èlái) was a bodyguard for King Zhou during the Shang Dynasty of ancient China. He was an ancestor of Feizi, the founder of the state of Qin. According to the Records of the Grand Historian (Shiji) by Sima Qian, Elai was known for his immense physical strength.
In the historical novel Romance of the Three Kingdoms by Luo Guanzhong, Cao Cao, impressed with Dian Wei's strength, states "This is old Elai again." Thus this fictional nickname of Dian Wei stuck with him, and he was henceforth known as "Elai" Dian Wei.
