Erlang Shen

Erlang Shen, also known as the Lord of Sichuan, is a Chinese god with a third truth-seeing eye in the middle of his forehead. He is the nephew of the Jade Emperor and is known as the greatest warrior god of heaven. Erlang Shen may have been a deified version of several semi-mythical folk heroes who helped regulate China's torrential floods dating variously from the Qin, Sui, and Jin dynasties. In the Ming semi-mythical novels Creation of the Gods and Journey to the West, he is the second son of a mortal and the Jade Emperor's sister Yaoji. In the former, he assists the Zhou army in defeating the Shang. In the latter, he goes on a journey to the west with Tang Sanzang to protect him from the Monkey King, Sun Wukong.
