He is a character from Mortal Kombat 5: Deadly Alliance. During the years that Shang Tsung sponsored the Mortal Kombat tournaments on Earth, The Outworld master Bo' Rai Cho was secretly training warriors for competition. It was even speculated that it was he who brought the fighting style of Drunken Boxing to Earthrealm. After many years, he finally discovered the Shaolin monk Liu Kang and taught him the martial arts moves he needed to defeat Shang Tsung. Later, with the tournament securely in the hands of the Shaolin, his teachings were no longer needed and he returned to Outworld. Bo Rai Cho had been unable to complete against Shang Tsung in the Mortal Kombat tournaments on Earth. His Outworld birthplace guaranteed that his victory would have been in the name of Shao Kahn. But the conflict this time was not a tournament to prevent an evil emperor from consuming another realm. This time the battle was to save his own realm from the tyranny of two evil sorcerors. Nothing could hold him back from the challenge that lay before him. The wrath of Bo Rai Cho would be unleashed once again. Bo Rai Cho looked gruff, but beamed inwardly. With their victory over the Deadly Alliance complete, Kung Lao had liberated Outworld from its greatest threat. Despite the years that had past since training his last student, his skills had proved useful once more. He was elated, but it would be inappropriate to express such emotions in front of his newest apprentice. Kung Lao invited his master to return to Earthrealm to teach more warriors at the Wu Shi Academy. The success of his apprentice gave him renewed confidence in his training skills and for the first time, a clear purpose in life. Bo Rai Cho offered only token resistance. He accepted the offer because the defenders of Earthrealm could certainly use his help, but more importantly because Earthrealm's rice wine put Outworld's liquor to shame.
