Dragon Ball Consumption – Draws the Dragon Balls into his mouth and swallows them; used to transform into Omega Shenron. Once Syn Shenron was overpowered by a newly restored Super Saiyan 4 Goku, he desperately swallowed the Dragon Balls, thus becoming Omega Shenron. In this state, after absorbing the Dragon Balls he attains all of the abilities of his fellow Shadow Dragons by utilising his Power Abduction ability, including:
Aftershock: Taken from Naturon Shenron. Omega used this technique to hurl Goku and his friends and family into the air, right before performing Dragonic Rage.
Dragon Thunder: After becoming Omega Shenron, he has shown the ability to use this attack in its traditional form (Dragon Thunderclap), and he later modifies it for close-quartered combat: instead of firing bolts of lightning, he flies under the opponent with his back turned upward to them and stretches the spikes on his back, stabbing them through wherever they hit. After spiking the enemy, he sends lightning through the spikes and electrocutes them before throwing the enemy down. He used this on Vegeta and skewers his left shoulder. In Dragon Ball Z: Budokai 3 and Dragon Ball Z: Infinite World, he summons lightning in order to attack the enemy, which he can store in the body before releasing it.
Electric Slime: Taken from Rage Shenron, Omega Shenron converts into electric slime, but without using electricity. It is unknown if he can absorb electricity to grow stronger, or if water can short it out. Using this, he is able to completely reform himself just like Majin Buu. Used to survive Goku's 10x Dragon Kamehameha.
Heat Armor: Taken from Nuova Shenron, Omega Shenron envelops himself in high temperature to block attacks and burn his opponents at the same time.
Whirlwind Blade: One of Oceanus Shenron's super attacks, allowing its user to blast foes into the sky with a massive hurricane. Omega uses a red colored version of this attack. Strangely, his attack seems to lack the cutting power of Oceanus Shenron's attack. Omega's version was named Whirlwind Blade in Dragon Ball: Xenoverse.
Super Ice Ray: Omega Shenron takes this freezing ability from Eis Shenron. He uses this technique to completely freeze Goku before using the Whirlwind Spin.
Whirlwind Spin: Another of Oceanus Shenron's signature moves, which Omega Shenron uses in the same way. He places both hands close to him with his middle and ring finger curled inward before throwing them forward and throwing out huge blasts or wind, though they do not cut like Oceanus Shenron's wind did.
Near the end of his battle against the Z Fighters, Omega Shenron displays the ability to release negative energy from his body in the form of dark clouds. The energy covered the entire Earth, causing massive disasters and threatening to consume the planet, if not the entire universe. This ability may be based on Haze Shenron's powers of pollution, but on a greater scale.
Negative Karma Control - In the Adventure Modes of the video games, Dragon Ball Z: Ultimate Tenkaichi and Dragon Ball Z: Extreme Butōden, Omega Shenron possesses the ability to control negative energy to effect the universe or other beings. In Ultimate Tenkaichi, Omega Shenron corrupts Ultimate Shenron with negative energy after using the Ultimate Dragon Balls to turn Earth into a living hell to prevent others from undoing his wish. Though the Ultimate Tenkaichi hero defeats and kills Omega Shenron, his negative energy persists. Though the hero manages to free Ultimate Shenron from the negative energy, Ultimate Shenron reveals that due to the negative energy of Omega Shenron that remains and that produced by the nature of the wish itself it is beyond his power to undo the wish, so the hero has him revive all those killed as a result of Omega Shenron's wish and decides to search for another way to return the world to normal without the Dragon Balls. In Extreme Butōden, he uses negative energy to warp time and space in order to force Goku and his allies to generate enough negative energy as a result of them fighting various villains who return due to the space-time warping, to create the Ultimate Minus Energy Power Ball which is said to be capable of destroying Universe 7. However Goku uses the divine ki of his Super Saiyan God form to seal both the attack's energy and Omega Shenron in the Ultimate Dragon Balls. Presumably this ability is tied or derived from his Negative Karma Ball technique.
Negative Karma Ball – Omega Shenron's own unique ability and most powerful attack, which can destroy an entire planet easily. He pushes his chest forward, sending pure negative energy through the Dragon Balls on his chest and outward. Small red streams of energy fly out and start to form a ball of crimson energy in front of him that becomes yellow in the center. He puts so much energy into the ball that it is somewhat like Cooler's supernova attack, as it takes up the whole sky before he condenses it into a ball the width of his torso. He attempted to use this to destroy Super Saiyan 4 Gogeta, but Gogeta has shown to be mighty enough to knock it into space and cause it to release a planet-sized explosion. This attack is said to be the negative version of the Spirit Bomb.
Ultimate Minus Energy Power Ball - A more powerful version of Negative Karma Ball that is mentioned in Dragon Ball Z: Extreme Butōden. Though the attack is never actually seen in-game it is basically a Negative Karma Ball created using enormous amounts of negative energy and implied to be capable of destroying Universe 7 by both Omega Shenron and in a conversation between Whis & Beerus. It is revealed to be the reason why Omega Shenron warps time and space in the game's Adventure Mode as he uses the battles with the revived villains to generate the energy needed for the technique and manages to complete it after Goku's battle with Broly and Hirudegarn. However Super Saiyan God Goku manages to seal Ultimate Minus Energy Power Ball and Omega Shenron in the Ultimate Dragon Balls.

Dragon Booster – After Omega Shenron was critically wounded by Gogeta, he reverts to his previous form, giving Goku the chance to take the Four-Star ball. A few time after Goku swallowed it, Nuova Shenron comes back and envelops Omega Shenron, now containing six balls, in a fire beyond the temperature of the Sun. Upon hearing that Nuova is immune to the intense heat, Omega Shenron breaks into pieces, sending the corrupted Dragon Balls into Nuova and, with them, his own spirit. After taking cover from the fiery attack, Omega Shenron reconstitutes himself from within Nuova's body, destroying the dragon from the inside and regaining the Four-Star Dragon Ball. This ability may be taken from Naturon Shenron, who also uses his Dragon Ball to absorb his victims. Named in the Dragon Ball Z Collectible Card Game.
