Mortal Kombat X/Liu Kang
Liu Kang was Earthrealm's champion, winner of two straight Mortal Kombat tournaments. Under Raiden's tutelage, Liu Kang defeated both Shang Tsung and Shao Kahn, becoming a legend throughout the realms. But when Shao Kahn's Outworld forces invaded Earthrealm, Liu Kang split with Raiden over how to respond. During a disagreement between them, Liu Kang was accidentally killed. His soul was collected by Quan Chi, who used it to create an evil "revenant" version of Liu Kang. He now serves Quan Chi and the Netherrealm.
