"This isn't a game and how dare you criticize your own creation. We're here because of you. All the Shadow Dragons were born because you misused the Dragon Balls remember? It all started with you. Your world is crumbling because of your actions. You were warned about the over use but you didn't listen. This is all your fault. Hmm a noble monkey? If you feel so bad about it then maybe death should be your penance."

- Syn Shenron Syn Shenron, known as Omega Shenron in his final form, is the final villain of the Dragon Ball GT anime series. He is the last of the Shadow Dragons and the dragon of the One Star Ball. Syn Shenron later becomes Omega Shenron, after he absorbs all the other Dragon Balls and gains the powers of the other Shadow Dragons.

History
Syn Shenron, like his fellow Shadow Dragons was born from the negative energy created within the Dragon Balls, every time a wish was made. In his case, it was the wish that brought back everyone who had been killed by Frieza and his men. Because of the size of this wish, Syn Shenron was the most powerful out of all of the Shadow Dragons.

Engaging Goku
Syn Shenron first appeared after Eis Shenron's defeat at the hands of Super Saiyan 4 Goku and Nuova Shenron. He killed Nuova Shenron for his betrayal and when Goku reprimanded him for killing one of his own kind, Syn Shenron told Goku that he was the one who created the Shadow Dragons in the first place, because of his overuse of the Dragon Balls. They began to fight, with the battle going in Syn Shenron's favor due to Goku being blinded by Eis Shenron earlier. Though Goku was able to get in a few hits and even a Kamehameha wave, this did nothing to the dragon and he left Goku hanging unconscious from Fairground tower.

Just as he was about to move in for the killing blow, Syn Shenron found himself confronted by Gohan, Goten, Uub, Pan, Trunks, Chi-Chi, Videl, and Mr. Satan. While Uub kept the dragon busy, Gohan, Goten, and Trunks gave their energy to Goku. Though Syn Shenron defeated Uub with little effort, Goku managed to recover and the second round began. However Goku was the one dominating the battle now and Syn Shenron found himself unable to match the saiyan. After the dragon attempted a trick using a clock, Goku seemingly wiped him out with a Kamehameha wave. However Syn Shenron wasn't beaten yet and he used his special ability to swallow the other six Dragon Balls into himself, resulting in the powerful Omega Shenron.

Power of the Ultimate Dragon
Though Goku was able to take on Syn Shenron, Omega Shenron was another story and the Saiyan found himself unable to win. Though he regained his eyesight and blasted the dragon with a Kamehameha wave, followed by a Dragon Fist, Omega simply regenerated, an ability he had gained. Goku desperately prepared a self-destruction attack to kill Omega Shenron, until Vegeta arrived on the scene and, with use of a machine that generated the Blutz Waves needed for the transformation, became a Super Saiyan 4 as well. Despite this, Omega Shenron easily took on the pair, until they performed the Fusion Dance and became Gogeta, who easily managed to take on the Shadow Dragon. Gogeta then assaulted him with his Big Bang Kamehameha attack, which was so powerful, Omega Shenron spit up the Dragon Balls, reverting back to Syn Shenron. However as Gogeta was about to perform the attack again, he defused back into Goku and Vegeta.

Thinking quickly, Goku swallowed one of the Dragon Balls, preventing Syn Shenron from becoming Omega Shenron again. Syn Shenron fought both Goku and Vegeta and still managed to take them on. The two attempted to perform fusion again, but it failed and Goku reverted to his child state. The Shadow Dragon resumed his attack, only to be confronted by Nuova Shenron, who had been revived by the positive energy in Goku. Nuova Shenron attempted to use a self-destruction attack, only for Syn Shenron to survive and become Omega Shenron again. He attempted to use an attack to blow up the Earth, but Goku blocked it, apparently dying in the blast. Omega Shenron fought the rest of the Z Fighters and defeated them easily, only for Goku to appear and prepare his Universal Spirit Bomb.

The Dragon's Demise
"Wait, wait. Hold on!"

- Syn Shenron's last words

While Goten, Gohan, and Trunks distracted Omega Shenron, Goku gathered energy from all over the universe and amassed it into a powerful Spirit Bomb. The Shadow Dragon tried to blast at Goku, but it had no effect and finally the Saiyan finished gathering energy. Omega Shenron attempted to plead with Goku, but it fell on deaf ears and the Shadow Dragon met his end at the hands of the Universal Spirit Bomb, before Shenron appears without being summoned.

Powers
Unlike most of his siblings, Syn Shenron has no elemental powers and he is simply the strongest Shadow Dragon. The only special power he has is his ability to swallow the Dragon Balls and gain the powers of the other Shadow Dragons. Like most of the other Dragon Ball characters, Syn Shenron can use energy in the form of blasts and flight. Also like most other Dragon Ball characters, he has a few signature attacks, such as his Gigantic Blaze attack, which is where he generates an explosion of energy around his enemy, and the Negative Karma Ball, which is a large sphere of negative energy. After becoming Omega Shenron, he gains the powers of all the other Shadow Dragons, such as Eis Shenron's Ice Ray and Oceanus Shenron's Whirlwind Spin. He can also use a more powerful version of his Negative Karma Ball, the Minus Energy Power Ball.
