Bo' Rai Cho taught several great warriors, including Liu Kang, Shujinko and the legendary Muso Gonnosuke. Bo' Rai Cho originates from Outworld but has not, however, participated in a Mortal Kombat tournament, knowing that if he wins, his victory would be in the name of Shao Kahn due to his status as an Outworlder. So he instead chose to utilize his fighting skills to train Earthrealm warriors. Later, he fought against Onaga in the Battle of Armageddon, siding with the Forces of Light, but ultimately died while trying to reach the top of the Pyramid of Argus.
