Sleeper

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 Mac Gargan. 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.
