Black Zero

The original Black Zero appeared Pre-Crisis in Superman #205 (1968), in a story entitled "The Man Who Destroyed Krypton" written by Otto Binder with artwork by Al Plastino.[1] This Black Zero revealed to Superman that he was a space saboteur who destroyed planets.[2] He had been hired to destroy Krypton, and discovered that the internal stresses which would have destroyed it in any case were dying down, necessitating his involvement to ensure it exploded.[3]

In the present day, Black Zero came to Earth, threatening to destroy it as he did Krypton. In desperation, Superman released Jax-Ur, a prisoner of the Phantom Zone, who wished to avenge Krypton's destruction. As he launched a devastatingly powerful missile toward Earth, Black Zero attacked Jax-Ur with a red kryptonite bullet, causing his body to mutate wildly into several serpent-like forms. This proved to be Black Zero's undoing; while Superman saved the Earth from the missile, Jax-Ur transformed into a Medusa-like form, turning Black Zero to stone with his gaze. Black Zero's body was then shattered by Jax-Ur, in recompense for what he had done to Krypton.

This story suggests that, were it not for something none of them knew, Jor-El would have been wrong and the Science Council right. E. Nelson Bridwell hypothesized that what Black Zero had noticed was the Green Lantern Tomar Re's attempts to prevent the destruction (as seen in Superman #257 (1972)), meaning the two sets of interference canceled each other out, and Jor-El was right after all.

Black Zero had the ability to create "psycho-molecules" with his mind, which he could then shape into any form of matter he chose. His brain had been fitted with a plastic coating, preventing him from being hypnotised. He could make his body intangible, enabling him to pass through solid objects. He was a skilled engineer, able to create weapons and devices that could destroy entire planets. He was also skilled in the art of disguise.

Black Zero was an alternate version of Superboy from a reality in which Superman never returned from the dead after his battle with Doomsday. This reality mirrored the main continuity with Paul Westfield, the Executive Director of Project Cadmus, secretly using his own cellstock for his team of scientists to immediately create a human clone that would be genetically engineered to look like Superman with powers deriving from a telekinetic field. Instead of the Newsboy Legion clones releasing him prematurely, the clone went through the full artificial maturation process to match the age of the original and became the new Superman. However, he believed that he was perceived as a usurper and resented by the people for not being the original Superman. After a battle with his reality's versions of Brainiac, Maxima, and Metallo led to the deaths of Supergirl, Brainiac and 318 civilians, a public backlash began against the new Superman and other clones that the people dubbed "genetix"; this led to Congress demanding the shutdown of Project Cadmus with the Guardian and the original directors of Project Cadmus sans Westfield abandoning the project.

After the Guardian was killed by an anti-genetix mob, the new Superman retreated to the original Superman's Fortress of Solitude and sought guidance from Kryptonian history. When he learned of the Black Zero clone liberation movement from Krypton, he discarded the name of Superman and took Black Zero as his new name. He decided to defend genetix everywhere and stop the anti-clone lobby by any means necessary. Turning Project Cadmus into Fortress Cadmus and creating an army of Guardian clones known as Stormguards with no previous memories of the original Guardian, Black Zero began a war in which most of his Earth's heroes were destroyed and cloned as soldiers for Cadmus with extreme changes by his head geneticist Dabney Donovan.[6]

After conquering his Earth, Black Zero became aware of the existence of other realities when he encountered the Challengers of the Unknown, who arrived to his homeworld from a dimensional doorway. Metron of the New Gods, who appeared shortly after the Challengers, struck an agreement with Black Zero and offered him the chance to enter Hypertime via the construction of a reactor powered by the element Hyperium. Black Zero "rescued" other worlds in which he felt that genetix were being oppressed and left the conquered world's version of Paul Westfield in charge of the genetix on that world. The Challengers attempted to stop him by launching commando raids against Black Zero and his forces and smuggling themselves to whatever world was next in his crusade. To Black Zero's bafflement, the Superboys of these worlds often stood against him, leading him to store them in stasis chambers similar to the clone banks of Krypton. A Superboy from another reality that Black Zero tried to conquer escaped with a stolen Hyperjacket from Fortress Cadmus, but was shot with a laser by the Paul Westfield of his reality resulting in fatal burns. He warned the Justice League of the main continuity of Black Zero's coming before he died.[7] Learning that the deceased Superboy was a genetic match and using the Hyperjacket repaired by the Gadget Guru of the Hairies, the Superboy of the main continuity traveled to other worlds where he learned of Black Zero and eventually landed on an Earth in which Superboy was Kal-El.[8]

After Superboy was in possession of the hyperjacket, Black Zero followed him to each world that he visited, capturing all of the versions of Superboy that Kon-El encountered. When he reached the world of the Kal-El Superboy, he captured Krypto and ambushed both Kon-El and Kal-El using his Stormguard forces and his own powers. Learning that Superboy wasn't the Superboy that stole the hyperjacket, Black Zero sent him to Fortress Cadmus and revealed his true identity and told his story to Superboy via the latter in a mnemonic chair that showed parts of Black Zero's life in virtual reality. He revealed his plans to take over Superboy's reality, which he used a supposed anti-clone sentiment as justification, and to use one of the Doomsdays that he collected from alternate realities against Superman. After revealing his plan, a reformed version of Knockout from the deceased Superboy's world attacked with the Challengers of The Unknown, posing as Stormguards, and went after her reality's Paul Westfield. Westfield leaped into the Hyperium reactor and unknowingly erased every Paul Westfield in existence as well as himself. Angry at the loss of Westfield, who he considered a father figure, Black Zero sent Superboy, Knockout, and the Challengers to the Doomsday chamber to be destroyed while he prepared to take over the next world. Superboy and the Challengers escaped with Knockout making the ultimate sacrifice against the Doomsdays.[9]

Black Zero was eventually defeated by a combined effort from Superboy, the Challengers of the Unknown, and all the other Superboys imprisoned at Fortress Cadmus. After Metron sends the Superboys and Stormguards back to their own realities along with immobilizing Black Zero with a Mother Box, he provides a ship for the Challengers and Superboy to fly through the hyperium reactor and into a hyperstorm to return home. Superboy intended to take Black Zero to his homeworld to keep watch over him, but Black Zero attacks the ship with his tactile telekinesis. Superboy dives into the hyperstorm and is almost struck by it until Black Zero rescued Superboy and saves the Challengers except for Matthew "Red" Ryan. Superboy attempted to convince Black Zero that his mission was wrong and to give people a chance, but Black Zero is engulfed by hyperstorm energy and disappears before responding to Superboy.[10]

After his "death", Black Zero became a reminder to Superboy as to what could happen if he ever went out of control. During a battle with Etrigan over an enchanted armored gauntlet known as "Hyssa's Fist", Superboy puts on the gauntlet and while his strength increased, his costume was transformed into an exact copy of Black Zero's costume with the S-shield on the gold harness. He quickly used his tactile telekinesis to disassemble the gauntlet from his right hand.[11]

Black Zero's main unique power is an advanced form of "tactile telekinesis". Like Superboy, it is a telekinetic force field that surrounds his body and allows him to simulate superhuman speed, strength, flight and invulnerability. Tactile telekinesis also allows him to disassemble machines and other complex constructions by touch. But unlike Superboy, Black Zero's field provides him with resistance to energy attacks and he could use tactile telekinesis to telekinetically hold an opponent immobile.

As he explained to Superboy, Black Zero's human DNA was made to be genetically similar to that of Superman's DNA. Like Superboy, he is a living solar battery with his tactile telekinetic powers being fueled by solar energy. Grown to a full adult by the Project Cadmus of his reality, Black Zero gained powers similar to Superman due to his advanced age such as heat vision and super hearing.

With the combination of his tactile telekinesis and his simulated Kryptonian powers it is implied that Black Zero is more powerful than Superman. He easily seems to hold his own against multiple versions of Superboys, even the vastly powered Pre-Crisis Earth-1 version. Black Zero also seems to be well prepared to conquer a reality where he will have to fight Superman after his army of Doomsdays are disposed of.

Black Zero wears a black costume with red accents offset by a red cape, red belt at the waist, gold harness with a black "0" on his chest, gold belt on the right leg, and a pair of black glasses. Additionally, he wears a "hypergun" on his right arm equipped with hyper-bullets which he can fire at his targets and instantly transport them via hypertravel directly to his stasis cells at Fortress Cadmus.

• In the Smallville episode "Kandor", Major Zod and his armies went to war with the terrorist group Black Zero, who later destroyed Kandor.
• The Black Zero terrorist organization is a significant aspect of the plot of the TV series Krypton, led by Jax-Ur aka Sela-Sonn after she was expelled from the Science Guild.

• Black Zero is heavily featured in Man of Steel. In this version, The Black Zero was a Kryptonian prison frigate originally designed by Jor-El to transport criminals into the Phantom Zone. It was used to imprison General Zod and his battalion the Sword of Rao following their failed coup, and, following Krypton's destruction, was later repurposed as their command ship. General Zod proceeded to utilize the ship as a means of searching the universe for Kryptonian survivors. When Kal-El triggered the distress beacon in his discovered Scout Ship 0344, the Sword of Rao travelled to Earth in their resumed pursuit of the Growth Codex. Upon finally reaching Earth, Zod attempted to use a World Engine in the Indian Ocean to terraform the planet into a world suitable for Kryptonians, but was defeated by Emil Hamilton's activation of the Phantom Drive aboard Kal-El's Starcraft, sucking the ship and Zod's soldiers back into the Phantom Zone above Metropolis.

• Black Zero is seen again in the film's flashback Batman v Superman: Dawn of Justice, when Bruce Wayne arrives in his helicopter upon learning of the Metropolis invasion, heading to the Wayne Financial Building before it collapses, killing the dozens of people left inside, much to the horror of Bruce Wayne, who saw it happen.
