Shujinko, Mortal Kombat: Deception Intro

Onaga, the Dragon King, is a character in the Mortal Kombat fighting game series. He made his debut in Mortal Kombat: Deception, in which he also served as the main antagonist and final boss. He then became playable in Mortal Kombat: Armageddon.

About OnagaEdit

Onaga was introduced in Mortal Kombat: Deadly Alliance under the cryptic name of the "Dragon King", the long-dead ruler of Outworld preceding Shao Kahn. Not much was known about him, except for the fact that his army was deemed undefeatable but, at his untimely death, allowed itself to be mummified and kept in an ancient tomb that remained uncovered until the necromancer Quan Chi stumbled upon it. Onaga is one of the series' characters through which the One Being is said to work. His most important powers include superhuman strength, resistance to all forms of magic, and the innate power to raise the dead.

Combat characteristicsEdit

Onaga appears to be one of the strongest beings in the entire Mortal Kombat series . His own power is ambiguous overall, but since Shao Kahn preferred poisoning Onaga as opposed to fighting him, he can be presumed to possess enough power that even Shao Kahn feared facing him. When Onaga had the Kamidogu, he became nearly unstoppable and any direct confrontation with him was nigh impossible. This is displayed when the two strongest sorcerers, Shang Tsung and Quan Chi, combined with the power of Earth's Thunder God, Raiden, tried to stop him. The blasts from all three only pushed him away as he advanced towards them. Not even a self-destruct blast from Raiden was sufficient in destroying him, only doing little, if any visible damage. Being a dragon, Onaga is able to exhale flames in a concentrated ball of fire or a stream of fire, similar to a flamethrower. In Deception, Onaga was able to fly, but doesn't use this ability when fighting in Armageddon. He also possesses a degree of magic as he was able to spread his influence in the form of a spiritual avatar named Damashi, whom he used to manipulate Shujinko for many years to gain what he needed, also displaying his cunning and tactics.

It is later revealed in chapter 36 of Mortal Kombat X (Comic Series) that he also possessed regenerative abilities such as being able to regrow a hand if one was cut off, an ability which Goro sought out to regrow his own arms after losing them to Kotal Kahn in kombat.

Signature movesEdit

  • Dragon's Fire: Onaga launches a fireball at his opponent. (MK:D, MK:A)
  • Flame Breath: Onaga spews flames, immolating the opponent and setting them up for an additional combo. (MK:D, MK:A)
  • Jumping Stomp: Onaga jumps up and creates a shockwave when he lands, causing damage to the opponent if they are grounded. (MK:D, MK:A)
  • Sliding Kick: Onaga lunges forward with a foot extended, tripping the opponent if he makes contact. (MK:D, MK:A)
  • Dirty Face: Onaga creates a small shockwave which knocks the opponent back a bit. (MK:D, MK:A)

Other movesEdit

  • Super Powerbomb: After capturing his foe, Onaga flies up into the air and powerbombs the foe headfirst to the ground. (MKD)


  • Onaga's name may be derived from "Ō Nāga", which means "Great Dragon" in Japanese.
  • Onaga's throw in Deception resembles a Super Powerbomb where he flies up into the air after capturing his foe and powerbombs the foe to the ground, but it is changed into a juggernaut boss' regular throw in Armageddon.
  • When fighting Onaga in Deception, touching one of the Kamidogu results in him doubling over in pain. When combos are performed on him during this state, they actually do more damage than they normally would.
  • While Onaga is unplayable in Deception outside of third-party cheat devices, there is evidence that he was meant to be an unlockable character: an unused ending for Onaga that can be found in the Krypt, as well as Puzzle Kombat models for the character.
  • As a playable character, Onaga only has one fighting style (Dragon, which is his own style and not to be confused with the actual Dragon fighting style that other characters in the game use) that cycles repeatedly when the Change Style button is pressed. Also, in the on-screen move list, only one of his special moves is listed, and one (non-working) combo is listed under his fighting style.
  • Reportedly, playing as Onaga in Puzzle Kombat is very difficult, as the character model's wings obscure a good part of the player's screen, and his special builds up very slowly. Likewise, playing against him is also hard, as his wings conceal what he is going to do next.
  • Onaga is the second boss in the series to be immune to projectile attacks, the first being Motaro. Unlike Motaro, however, Onaga does not reflect the projectile back at the opponent.
  • Onaga is the first final boss of the series with a bestial appearance as opposed to the more human-like bosses of past games such as Shang Tsung, Shao Kahn, and Shinnok.
  • If a character was to do a low kick ending combo to Onaga in Deception, he can be heard saying "NO KICKING!" in a somewhat whiny nature.
  • Although part of the original Forces of Darkness team-up, Onaga does not appear much in the opening to Mortal Kombat: Armageddon. His only appearance shows him grabbing onto Shao Kahn and flying away.
  • Onaga is most vulnerable to Liu Kang's Bicycle Kick.
  • In Raiden's ending in Deadly Alliance, Onaga was briefly seen with an entirely different look compared to his current design.
  • Onaga makes a brief cameo during two of Raiden's visions and is mentioned in Shao Kahn's bio in Mortal Kombat (2011).
