Siang is the combination of two Shaolin monk brothers, Sing and Sang, who have the special ability to fuse their two bodies into one warrior. He is a non-canon character from the Malibu Comics. He was considered to be the Order Of Light's greatest champion, until he was apparently killed by Goro, the two ripped from each other while combined. Sang survived the onslaught, but his brother had died. Sang then joined with his dead brother once more to form Siang, making the two inseparable. He then came under the control of Shao Kahn, who possessed a Deathstone - a special stone/gem that had the power to control the dead. Because Siang was only half-dead, he maintained a mind of his own, yet was still under Kahn's control.
Siang eventually encountered Scorpion, and related his story to him. Scorpion had at this point come into possession of the Deathstone, and promptly destroyed it before Siang's eyes. Siang savored his freedom, but only for a moment as Scorpion immediately murdered him, proclaiming that only the dead were free.
