Powers in comics:

Symbiote Biology: Sleeper can amplify the physical characteristics of its host when bonded to it, it can also grant it the ability to produce chemicals although this is limited to Sleeper alone.[7] Even without a host it can manifest a human form or any other.[11]

Superhuman Strength

Superhuman Durability

Superhuman Stamina

Regenerative Healing Factor

Genetic Memory

Wall-Crawling

Constituent-Matter Generation

Offshoot Generation: Sleeper is capable of being separated into offshoot symbiotes that can be bonded to other hosts while being remotely piloted by the main one.[20] It can also use self-assembling, remote-resonant ectoplasm to create a working copy of itself while doing another thing on the sidelines.[27]

Constituent-Matter Manipulation

Webbing Generation[9]

Camouflage Capabilities: Like many symbiotes, the Sleeper symbiote can shift its physiological semblance into a host of different shapes and forms i.e. mimicking forms of clothing, camouflaging with its surroundings, emulating other people's visages, etc. What makes this particular Symbiote unique is its ability to manipulate ambient light in order to become invisible. This in conjunction with using its hormone abilities enables it to confuse the sensory systems of others, thereby making it the perfect stalker.[1]

Augmented Visual Senses: The Sleeper symbiote was capable of seeing M'lanz's ship, despite it being cloaked and invisible to both the naked eye and human technology.[7]

Chemokinesis: As a result of its unique biology, the Sleeper symbiote is capable of producing liquid and aerosol chemicals with a variety of effects - including inducing various emotional states, tranquilizing targets, psychological manipulation, and secreting corrosive chemicals for offensive purposes. This also affords it a form of telepathy, using pheromones to interject its thoughts into others' minds.[7] This also grants it a superior cloaking ability to other symbiotes, generating pheromones to almost-completely mask its presence.[1] It is also capable of using chemokinesis as a means of rocket propulsion, enabling it to traverse space,[3] and produce acid.[9]

(in comics) 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.[4]

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.[5] 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.[6] 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.[7]
