Editing Syn Shenron (section)

=== ''Dragon Ball GT'' ===
Syn Shenron first appears after the defeat of Eis Shenron at the hands of Super Saiyan 4 [[Goku (Dragon Ball GT)|Goku]] and Nuova Shenron, the only Shadow Dragon with good within. Disgusted at the Four-Star Dragon's acts of mercy towards the Saiyan, Syn Shenron uses a sneak attack to dispatch Nuova Shenron before turning his attention to an enraged Goku. Goku criticizes him for killing one of his own kind, but Syn tells him not to criticize his own creation, reminding Goku that he is responsible for the birth of all seven Shadow Dragons due to his overuse of the Dragon Balls. Goku refuses to listen, declaring that he always used the Dragon Balls for the good of the Earth, and never used them once for his own selfish gain. Dismissing Goku's argument, Syn Shenron engages him in battle, quickly taking the advantage due to Goku having been blinded by Eis Shenron and tired out from his earlier battles with the other Shadow Dragons. Although Goku is able to land a few hits, none of them do any damage (even a direct hit from a 10x Kamehameha had no effect), and he is completely dominated by Syn Shenron, who batters him around and ultimately leaves him hanging unconsciously from a fairground tower.

Moving in for the kill, Syn Shenron is then confronted by the intervention of [[Pan]], [[Trunks]], [[Gohan]], [[Goten]], [[Uub|Majuub]], [[Chi-Chi]], [[Videl]] and [[Mr. Satan]]. Syn Shenron's next opponent is Majuub, who tries to stall the villain long enough for the Saiyans to lend their energy to Goku. Although Syn Shenron bests Majuub after a short fight, Goku manages to absorb enough energy from the other Saiyans to break his previous limitations and return to his Super Saiyan 4 state. Syn Shenron finds himself dominated, even with Goku being blinded, and attempts to ambush his nemesis by throwing a clock face like a sawblade. Even this proved futile, as Goku reversed the attack before blasting Syn Shenron with a 10x Kamehameha.

Although injured by the blast, Syn Shenron narrowly evaded the brunt of the attack and hid beneath the rubble of the fallen clock tower to evaluate the situation. Realizing that the rest of the Dragon Balls were nearby, he performed his secret technique, summoning the other Dragon Balls to him and swallowing them whole. Absorbing the mystical artifacts into his system, Syn Shenron revealed his true form: Omega Shenron, a larger, stronger version of himself with access to all of the abilities of his brethren.

Upon his creation, Omega Shenron first uses the Gigantic Blaze, an attack which blows Goku's family and friends away, turning the immediate surroundings into 'a cemetery', using lifeless ground for cover and the 'ruined buildings as a headstone'. After realizing he is no match for Omega even in his full power Super Saiyan 4 form, Goku begins doubting a victory. Out of nowhere, Goku regains his eyesight and blasts the dragon square in the chest with the 10x Kamehameha. While Omega attempts to counter the wave, he receives another surprise: Goku powers up and uses his Dragon Hammer, which seems to obliterate Omega. However, Omega survives by regenerating, an ability he gained after absorbing the Dragon Balls, and surprises Goku and friends in their premature celebration. To prove his superiority, Omega Shenron blasts Goku, along with his family and friends, in the air, before striking each of them with intense speed with a single punch or kick. Goku's family and friends are knocked out cold, while Goku himself can barely stand up to fight, despite his declaration that he would not ever give up.

Battered and broken, Goku decides to resort to desperate measures. He grabs Omega and puts him in an arm lock, preparing a self destruct to kill the dragon; however, the tables are turned when [[Vegeta (Dragon Ball GT)|Vegeta]] arrives on the battle scene. Using [[Bulma]]'s Blutz Wave Generator, Vegeta was able to attain Super Saiyan 4, and then proceeded to assist Goku in his battle against the Shadow Dragon. Even when the two Super Saiyan 4's teamed up on Omega, Omega still grossly outclassed them. However, while Omega was distracted, Goku and Vegeta performed the Fusion Dance, and fused into Super Saiyan 4 [[Gogeta (Dragon Ball GT)|Gogeta]], whose power surpassed Omega Shenron's to the point where he knocked away the Shadow Dragon without even appearing to move. Infuriated and bewildered, Omega tried several more attacks, but did not even come close to touching his foe. Eventually, the ultimate Shadow Dragon found himself lying face down on the ground from another failed attack, while Gogeta cheekily taunted him. In return, Omega Shenron blasted Gogeta with numerous energy bullets, only to find that it did absolutely nothing (other than get rid of a bothersome crick in Gogeta's neck).

Finally ready to begin counterattacking, Gogeta used Ultimate Impact on Omega Shenron, causing him to crash into a building. Gogeta then frightened Omega Shenron by splitting into five clones and preparing a "devastating attack", which turned out to be the Bluff Kamehameha, angering the dragon even more. Bent on revenge, Omega then used his ultimate attack, the Negative Karma Ball, which he described as the sum total of humanity's evil. He launched the ball at Gogeta, but the Saiyan easily kicked it away while simultaneously reversing its energy with his own life force. Consequently, Omega's attack ended up clearing the influence of the Shadow Dragons from the Earth (it is implied that this is why Gogeta spent so much time toying with Omega; by goading the dragon enough to use his ultimate attack, he was able to completely undo all the damage the Shadow Dragons did to the planet). With the taint of evil lifted from the planet, Gogeta finally prepared to end Omega with his signature attack: the Big Bang Kamehameha. The attack was so overwhelming, it caused Omega to spit up the Dragon Balls. Surprisingly, the dragon still lingered, albeit as the weaker Syn Shenron. Although impressed that his foe survived the hit, Gogeta informed Syn that they both knew that a second hit would be fatal to the Shadow Dragon, and immediately began charging another Big Bang Kamehameha. Too injured to evade, Syn could only wait for the end - which never came, as Gogeta defused before he could launch the final blow.

After getting over his shock at this turn of events, Syn Shenron immediately began reabsorbing the Dragon Balls to restore his ultimate form, only failing to claim the Four-Star Dragon Ball when Goku swallowed it himself. Despite consuming only six Dragon Balls, Syn became Omega Shenron once more, but with less-than-full strength. Nonetheless, Omega was considerably stronger than both Goku and Vegeta at Super Saiyan 4, forcing the duo to attempt another fusion. However, Omega was determined to prevent this from happening again, knowing that Gogeta would be far too powerful for Omega to handle, especially when Omega himself was not at full power; thus, he pursued the Super Saiyan 4's relentlessly to prevent their fusion. Eventually, Goku and Vegeta finally create an opening by using the Afterimage Technique to distract Omega, but the fusion fails due to Goku's exhaustion from his recent battles. Realizing this, Omega intentionally allows them to try the fusion once again, fully aware that the attempt would fail. Not only does it fail, but Goku reverts into his child state, rendering further fusion attempts useless.

Confident of victory, and tired of playing around, Omega Shenron continues his attack, but finds a pleasant surprise in the form of Nuova Shenron, who emerges from Goku's body. To the heroes' shock, Nuova joins Omega in battle, as the latter explains that his own negative energy has corrupted Nuova into a loyal ally. Initially, Omega allows the Four-Star Dragon to finish the Saiyans, only to be struck by a combined attack from Goku and Nuova, the latter having been purified by Goku's positive energy. Nuova then uses his ultimate attack to try and kill Omega, engulfing them both in an incredibly high-temperature orb of flames. However, Omega manages to possess Nuova's heat-resistant body by launching the Dragon Balls at his Four-Star brother, allowing him to emerge unscathed and regain the Four-Star Dragon Ball in the process. Having achieved his full power once again, Omega demolishes Goku and Vegeta (who had also lost his Super Saiyan 4 strength, just as Omega had predicted earlier) without much effort.

Omega then attempts to end the fight by powering up an energy sphere to destroy the Earth. Goku stops the ball from obliterating the planet, but is presumed to have been killed in the explosion, and Omega simply begins sending his energy across the Earth to eventually rip the entire universe apart. To his amusement, Vegeta, Gohan, Goten, and Trunks attempt to attack him, but they are completely outmatched by the Shadow Dragon. Omega takes his time to brutally impale and torture Vegeta, and then finally knock him out when Vegeta attempts to avenge Goku's supposed death. As Omega prepares to finish off Vegeta, Goku emerges from the crater of Omega's failed attack, readying the Super Ultra Spirit Bomb, his ultimate and final technique.

As Vegeta, Gohan, Goten and Trunks continue to distract Omega, Goku gathers energy from across the universe for his Super Ultra Spirit Bomb. Desperate to stop him, Omega repeatedly blasts Goku, even with a Negative Karma Ball, but his attacks are nullified by the Spirit Bomb's sheer energy. When Goku finally has the Spirit Bomb charged up, Omega lets go of his pride and attempts to talk his way out of the situation; unfortunately for him, Goku is far too disgusted by the dragon's evil to listen. With a defiant cry, Goku unleashes the Super Ultra Spirit Bomb; Omega is destroyed in the blast while letting out a loud scream, thus restoring the Dragon Balls and finally bringing the Shadow Dragons' evil to an end.
