U didn't see him in mkDA???? tehn u never finished the game with reptile.
The DK wasn't mentiioned untill now.... he was this great dragnon-like creature that ruled for a lot of time and he was the most powerfull....
He had an invincible army, and that's the army Tsung and Chi want to revive...

wait...isn't there something about a dragon egg that you can unlock in the krypt? does that have something to do with the dragon king? i'm not sure i remember correctly. i almost had the entire game cleared, koffins and everything, but some ass stole my memory card and i didn't feel like renting it to unlock all that stuff again.

The Dragon King was an ancient ruler of Outworld before Shao Kahn's rise to power. He had formed the greatest army that realm had ever known. An army so powerful that it had never lost a battle. In an attempt to gain immortality and rule Outworld forever, The Dragon King commanded his holy men to hatch the last known Great Dragon egg. Legends told that drinking the blood of a newborn dragon would bring eternal life only if the dragon was slain moments after hatching. Unfortunately, the Dragon King died prematurely. His holy men loyally continued to incubate the egg with the intent of eventually reviving the dead king with the dragon blood. His army allowed themselves to be ritualistically slain and were buried in the pyramid along with their sovereign to be resurrected as well some time in the future. Generations of the Dragon King's holy men have been incubating the egg in secret ever since. As the prophecy has been told through the ages... "Upon the birth of the last Great Dragon will the Dragon King return."

This is the Dragon King.
