Sing

Sing is a fictional character from the Malibu Comics' Mortal Kombat series. He is introduced as one half of a pair of twin brothers, who together form Siang, the greatest warrior of the Order of Light. Sing makes his debut in Mortal Kombat Blood and Thunder #1. The comic book states that individually, Sing and Sang possess exceptional skill and strength, but when they merge into a single body, their abilities double. As Siang, he tried to defeat Goro, but was easily killed, the two brothers being ripped apart from their merged form. After Sang's death, Sing chose to fuse with him one last time, never to separate again. Seeking revenge, he infiltrated Outworld and challenged Shao Kahn, who controlled him with an item called the Deathstone, making him an unwilling servant of the emperor. He later joined the resistance against Shao Kahn, but was ultimately controlled again. In battle, he was killed by Scorpion, freeing him from the control of the Deathstone.
