Kull-Ex was son of Kryptonian inventor who was about to design a new kind of vehicle on Krypton, however the blue print was lost and shortly thereafter, Superman's father Jor-El created a similar device by pure coincidence, and the vehicles (dubbed "The Jor-El") became popular among the people of Krypton. Kull-Ex's father was furious and believed that Jor-El had stolen the design for his personal gain. In reality, Kull-Ex had used the blue prints as drawing paper and later unknowingly fed it to a junk-eater at the Kryptonian zoo, and Jor-El came up with the similar idea on his own, and instead of gaining from it he gave the patent freely to the government. However, Kull-Ex's father was brutally jealous, and had his son promise to get revenge against Jor-El on his death bed. Kull-Ex would not get this chance right away, as they lived in the city of Kandor, which was shortly shrunk down in size and captured by Brainiac.

Years later, after the city of Kandor was recovered by Superman and placed in his Fortress of Solitude, Kull-Ex renewed his plans to get revenge against Jor-El; however since Jor-El was long dead, he targeted his son Kal-El (aka Superman) instead. Building a device to swap places with Superman, and created a life like mask to pose as the Man of Steel. He would then discredit the hero, ruining his reputation with poorly executed super-feats, and later wanton destruction. When Supergirl learned the truth, she would free Superman from Kandor. While the miniature Superman kept Kull-Ex busy, Supergirl and Krypto lifted the Fortress of Solitude into space so that they could get light reflections from Krypton to reproduce the events that happened the day that his fathers plans went missing. Realizing the truth, Kull-Ex ended his vendetta against Superman, revealed his actions to the people of Earth and allowed himself to return back to Kandor and restoring Superman to his regular stature.

The fate of Kull-Ex is unknown, however it's presumable he was erased from existence following Crisis on Infinite Earths, to date there has not been a New Earth incarnation of Kull-Ex seen in the bottle city of Kandor. If another multiverse version of Kull-Ex exists remains to be revealed.


Kull-Ex has the same physiology of Earth-One Kryptonians. When absorbing energy from a yellow sun (like the one around Earth) he would gain the various super-powers that commonly came to Kryptonians on such worlds: Super-strength, invulnerability, x-ray vision, heat vision, flight, super breath etc.

He was a genius inventor and created a device that could allow him to swap places with someone on Earth, shrinking them down to size and trapping them in the bottle city of Kandor, while he appeared on Earth at full size. He also invented a life like mask to disguised himself with the likeness of Superman.

  • This version of Kull-Ex, including all history and corresponding appearances, was initially erased from existence following the collapse of the original Multiverse in the 1985-86 Crisis on Infinite Earths limited series. However the ending of Convergence retroactively prevented that collapse saving all the alternate realities though in an "evolved" form. Even though versions of the character may have since appeared, this information does not apply to those versions.
