This article is a biography of Doomsday as seen in the Modern Age Continuity (1985-2011). For Doomsday's history in other continuities, see Doomsday.

The monster best known as Doomsday is roughly 245,000 years old. He has ravaged many worlds in that time and battled a number of powerful entities, including Darkseid, The Radiant, the Green Lanterns and the Guardians of the Universe, and, most famously, Superman—who he famously killed. This article details his history as seen in the Modern Age comics.


Doomsday Chained

Thousands of years into Krypton's obscure past, long before the humanoid Kryptonian race managed to gain dominance over the planet, Doomsday was originally an infant humanoid, probably a Kryptonian; he was known at this point simply as baby. An alien scientist known as Bertron saw the environment of his home world. During this time, Krypton was a violent and harsh world equivalent of hell, where only the absolute strongest lifeforms could afford to survive. Because of this, Bertron was influenced to create the perfect creature that could be suitable for the Kryptonian environment and decided to perform experiments on a baby. Due to the cruel nature of the experiments, the baby evolved into a killing monster, with a hatred of all life. (Superman/Doomsday: Hunter/Prey)

General Zod also claims to have been responsible for hunting down the "Doomsday terrorists", for releasing Doomsday. (Last Son of Krypton)

Intermediate Years

Doomsday vs Radiant

Doomsday is killed by The Radiant.

Doomsday was able to escape from Krypton on a random supply ship, which came regularly to bring supplies to Bertron and his team. From there, he began to rampage across the universe. (Superman/Doomsday: Hunter/Prey)

During this period, he had an epic struggle against the Green Lantern Corps, devastating their number by stealing and using one of their rings. Luckily, the Guardians of the Universe were able to stop him, but just barely. (Doomsday: Year One)

Doomsday also had his first meeting with Darkseid during this era, on a random planet. The two faced off, but did not fight. (Doomsday: Year One)

The final planet Doomsday invaded during this era was a highly advanced planet known as Catalan. All of their advanced technology was unable to stop him, until they created a superbeing made of pure energy, who they called The Radiant. This being was able to kill the seemingly unstoppable monster, and they wrapped him up in funerary clothes and tied him up as best they could, launching him into space. (Superman/Doomsday: Hunter/Prey)

Drifting through endless space, the coffin came to land on Earth, where it remained buried for years, dormant. (The Death of Superman)

The Battle with Superman

Doomsday Kills Superman

Doomsday and Superman deal a fatal blow to each other.

After a long period of dormancy, Doomsday awakened within his holding cell below the Earth and burrowed his way to the surface. He then started rampaging across the countryside, slowly making his way towards Metropolis.

He battled the Justice League, easily defeating them and severely injuring some of them. Soon, Superman had to get involved, to protect innocent bystanders.

The battle escalated, and soon it was only Superman and Maxima who fought against Doomsday. Maxima, however, accidentally blew herself up during the battle by igniting a large amount of gasoline all around her.

Superman then had to fight the monster himself. The battle finally worked its way into Metropolis, where finally, the two beat each other to death. There was one final, cataclysmic blow which killed both combatants.

Doomsday's body was then brought to a laboratory for study. (The Death of Superman)

Cheated Death


With all of Supermans energy including his last breath,Superman and Doomsday both hit each other with one powerful blow in the gut, both Superman and Doomsday were dead, or so people thought...

In fact, Doomsday was dead, but one of Doomsday's powers is that after being killed, he regenerates and comes back to life, resistant to whatever killed him after a period of dormancy. He was dormant in the laboratory where his regenerating corpse was being studied.

Cyborg Superman made a show of visiting him there, and angrily grabbing him, tying him to an asteroid, and throwing him into space. Unknown to the others, the Cyborg had planted a chip on Doomsday's back, which contained a backup version of his personality. (Reign of the Supermen)

Later, Doomsday awoke as his asteroid was being taken in by a cargo ship, which was headed to Apokolips. Doomsday killed the entire crew of the ship, and, when it landed, he began to rage across that planet's surface. Nothing there could seem to repel him, so Darkseid was forced to face him in person. This was Darkseid's second meeting with the creature. Doomsday defeated him in battle, taking advantage of Darkseid's arrogance.

The creature was then teleported off Apokolips, with Superman in pursuit, through a Boom Tube. He landed on Catalan, where The Radiant once again challenged him, this time with Superman's help; however Doomsday had adapted to the Radiant's power, and was able to kill him.

Doomsday came very near to destroying major reactors that would deal serious damage to Catalan, but luckily, Superman and Waverider were able to banish him to the end of time. (Superman/Doomsday: Hunter/Prey)

Doomsday Wars

However, Doomsday's story did not end there. Brainiac was able to retrieve him from the end of time, and temporarily inhabited his body.

He brought the body with him back to present-day Earth, where he created a new Engine City. There, he realized that Doomsday's will wouldn't allow him to be controlled for much longer. He began preparing Lana Lang's infant son as a new body for himself.

However, Superman was able to defeat him and foil the plan, separating Brainiac from Doomsday. The Justice League was able to trick Doomsday into a teleporter leading to the moon, and that teleporter was set to continuous cycle, leaving Doomsday in transporter limbo. The transporter was left in the hands of the United States Government.(The Doomsday Wars)

Imperiex War

During the Imperiex War, the United States Government, under President Lex Luthor, made the decision to release Doomsday as a weapon against Imperiex and his probes. Doomsday, reprogrammed to see Imperiex as his creator, Bertron, ravaged numerous Imperiex Probes, alongside Superman. However, when the two were confronted by Imperiex himself, Doomsday was hit with an ultra-powerful energy beam which vaporized his flesh, leaving only bones in space. (Superman: Our Worlds at War)

Doomsday Rex

In the aftermath of the war, Doomsday's body was left in the hands of the United States Government, where they augmented his body's regeneration. He grew back bigger and stronger, and then was released by The Joker. He attacked Washington, D.C., but Superman recognized that Doomsday had achieved sentience and then took advantage of Doomsday's fears, thus defeating him. The government once again took posession of the monster, and President Lex Luthor returned him to Darkseid's care via a Boom Tube. (Superman #175)

Apokolips Now!

The monster was kept on Apokolips, until Team Superman invaded, trying to retrieve Steel's soul, which had been taken by the Entropy Aegis. Doomsday was unleashed on the invaders, but he was then defeated by Natasha Irons, who was able to grow to incredible size. (Apokolips Now!)


Doomsday later began exploring his newfound sentience further. He became involved in a plot with Gog.

Infinite Crisis

Doomsday reappeared during Infinite Crisis, participating in the Battle of Metropoilis. However, he was quickly defeated by Superman and An alternate universe's Superman. (Infinite Crisis)

New Krypton

Doomsday New Krypton

Doomsday attacks Metropolis upon the arrival of representatives from New Krypton.

Doomsday reappeared shortly after Kandor was finally restored to its full size.

He attacked Metropolis during the first official meeting between the Kryptonians from Kandor and the Humans, which was taking place in Metropolis. A group of Kryptonians including Superman and Supergirl quickly flew him to the Earth's moon, where they beat him to death. The U.S. Military took the remains back to their base, where they studied him. (New Krypton)

Reign of Doomsday

Doomsday Steel

One of the new Doomsday clones attacks Steel.

Steel, Superboy, the Eradicator, and Cyborg Superman—the four Supermen who took Superman's place after he was killed by Doomsday—were seemingly targeted by Doomsday when he returned.

He had apparently gained the ability to imitate their powers—gaining steel armor from Steel, Tactile Telekinesis and Kryptonian Powers from Superboy, ray blasts from the Eradicator, and robotic body parts and weapons from Cyborg Superman.

He captured each of these heroes in turn and brought them aboard a space station. However, it was soon revealed that these were, in fact, separate clones of Doomsday who had been engineered with the powers of the four Supermen. The actual Doomsday was aboard the station, where he was being kept in a weakened, comatose state to be copied. (Superman: "Reign of Doomsday")
