Black star shenron (Ultimate Shenron)

Ultimate Shenron is a fictional character in the Dragon Ball franchise. He makes his debut in "A Devastating Wish", the first episode of Dragon Ball GT.
Ultimate Shenron is the third out of four eternal dragons introduced in Dragon Ball. Like Shenron (Black Smoke Shenron) and Porunga, he too can only be summoned using a particular collection of Dragon Balls, the Black Star Dragon Balls.
Like the original incarnation of Shenron, Ultimate Shenron is only capable of granting a single wish. However, his capabilities greatly outclass those of the other eternal dragons. For instance, death wishes do not exceed Ultimate Shenron's power. For wishes that do not exceed the regular Shenron's power (such as restoring someone's youth), the wish is still so powerful that only a second wish to Ultimate Shenron can permanently reverse it. After a wish has been granted by the deity, the Black Star Dragon Balls are catapulted throughout the galaxy rather than their respective planet, and a one-year countdown is issued for the host planet's destruction, which can only be undone if the Dragon Balls are returned to that planet within this time. In Dragon Ball GT, Ultimate Shenron is used to cause Goku's body to physically regress to childhood, in a wish accidentally made by Emperor Pilaf. He is later summoned by Baby in the episode "The Game After Life", where he is instructed to restore Planet Vegeta (renamed to the "Tuffle Planet") and relocate it to Earth's solar system.
While Shenron and Porunga are both shown to be comparable in size to a large skyscraper, Ultimate Shenron is shown to be larger than each of these eternal dragons combined. While coiling, Shenron has been shown as being roughly the size of Kami's Lookout. Ultimate Shenron on the other hand is so large that his head alone is roughly the size of the lookout. Also, while Shenron has his "whiskers" on the upper part of his mouth, Ultimate Shenron has them on the lower part of its mouth. Interestingly enough, he lacks the red eyes that the other eternal dragons have, and instead has yellow or blue-green ones.
