Omega Shenron

After Syn Shenron absorbs the other six Dragon Balls and corrupts them with his negative energy, he assumes his form of Omega Shenron, also called Super Yi Xing Long (超一星龍, Sūpā Yī Xīng Lóng (Īshinron), lit. "Super One-Star Dragon"). In the English dub he is usually referred to just as "Omega" while in this form. In this state, the One-Star Dragon Ball moves from his forehead to his chest, surrounded by the other six Dragon Balls (five when Goku swallowed the Four-Star Dragon Ball, which was originally located north-east of the One-Star Dragon Ball). The ten spikes on his body (two on his elbows, two on his shoulders, and six on his back) become even longer than before, most noticeably the two on his elbows, and he develops even more on different parts of his body, including his knuckles and shoulders. He loses the fleshy spikes on his chest, and his horns move closer together, with a narrower angle between them.

As Omega Shenron, being the dragon of absolute destruction, his brutal personality becomes more pronounced and he becomes intent on destroying everything and everybody that stands in his way. He is nearly invincible in this form and is only outclassed by Super Saiyan 4 Gogeta. He easily beats up Goku, Vegeta, Majuub, Gohan, Trunks, and Goten, and nearly managed to destroy the Earth through the mere release of his negative energies. In the end, it took a Spirit Bomb charged with energy from the whole universe to defeat him.

Omega Shenron also has a weaker version of this form briefly used when he does not have the Four-Star Dragon Ball, giving him six of the seven Dragon Balls. His appearance changes slightly in this version of the form, as his chest only has six Dragon Balls located on it.
