Sleeper

Sleeper's History

Birth

The seventh spawn of the Venom symbiote, Sleeper was the result of an unusual and difficult pregnancy. Delivered by Doctor Steven at Alchemax's astrobiology laboratory, the infant symbiote narrowly avoided being captured by the Symbiote Task Force and bonded to the Scorpion. Worried that bonding to a host at such a young age would corrupt it into a monster like its siblings, the Venom symbiote and Eddie Brock opted to leave it in the care of Alchemax; stipulating that it could only be studied in a non-invasive fashion.

First Host

As Sleeper matured and began developing unique chemokinetic abilities, Alchemax CEO Liz Allan proposed harvesting its secretions to turn a profit, though Eddie and Venom refused the offer and threatened to take action against Alchemax if Liz did so. When the Venom symbiote refused to return to its original host, the Kree soldier Tel-Kar, he took the Sleeper symbiote hostage and threatened to bond with and corrupt it unless it complied. Angered by the loss of its parent, the Sleeper symbiote used its pheromone manipulation abilities to interject into Eddie's thoughts and proposed bonding to him in order to save Venom. While Eddie was initially reluctant to do so, Sleeper broke free of its container and bonded to him, accompanying the Skrull Warbride M'lanz into space to track down Tel-Kar.

Insulted by M'lanz questioning its abilities, Sleeper knocked her out and - upon observing Tel-Kar had unleashed the bio-weapon on the Skrull space station it was contained within; set out without her. Tel-Kar attempted to immolate Sleeper, but the symbiote used its superior invisibility to catch him off-guard. Incapacitated, the Sleeper symbiote interfaced with its progenitor, who broke free of Tel-Kar's control. When Tel-Kar punctured M'lanz's hazmat suit to expose her to the bio-weapon, the Sleeper symbiote left Eddie to plug the hole. Temporarily bonding to M'lanz, the Sleeper symbiote returned to Earth while the Kree armada arrived and destroyed the facility. When Tel-Kar escaped and tried to kill Eddie and the Venom symbiote, the Sleeper symbiote bonded to and lobotomized him as revenge for what he had done to the Venom symbiote. Despite Eddie being dismayed by this, Sleeper bid him farewell and set out to explore the cosmos, using Tel-Kar's mindless body as a puppet host.

Space Adventures

At some point during its travels, Sleeper killed an alien monster as a planetery king asked. When the king asked to show Tel-Kar reveal himself, it revealed his putrefied face. The royal guards attacked him, leaving Tel-Kar to perishe as he was shoot by one of them. Ever since, Sleeper puppeted his dessicated corpse, eventually being drawn to Klyntar and learned of the existence of Knull, who tried to assimilate it into his dark hive-mind. Escaping, Sleeper realized that Eddie was in danger and returned to Earth as quickly as it could.

Absolute Carnage

Arriving on Earth, Sleeper protected Eddie's son Dylan and Normie Osborn from the Phage symbiote -- who alonside its siblings Riot, Agony, and Lasher had been corrupted by Knull and were serving Carnage; who had bonded to the primordial Grendel symbiote and was seeking to free Knull.[9] It tried to transfer to Dylan, but was subdued and captured by the Maker, who decided to kill it alongside is siblings despite Dylan's protests. When Dylan unleashed the Life Foundation symbiotes in an attempt to stop him, Sleeper was left trapped and powerless to help as the Life Foundation symbiotes merged into Hybrid and took over the Maker.
