Notable aliasesSL-4, the Fourth Sleeper

The Sleepers are five doomsday robots designed in Berlin by Nazi Germany as agents of destruction. After World War II, the Fourth Sleeper is entombed within an underwater crypt. The first three robots are activated by agents and sent to attack Europe. They consist of a giant human-like robot with blaster rays, a winged robot, and the 'brain', which resembles Red Skull and acts as a powerful bomb. Despite Captain America's attempts to stop them, the Sleepers combine and fly towards the North Pole. While pursuing the Sleepers, Captain America deduces that they intend to destroy Earth by digging into its core and detonating. To prevent this, Captain America boards the Sleeper in midair and detonates the bomb early, destroying the three Sleepers. [1]

The crypt containing the Fourth Sleeper is retrieved from the sea in modern times. When the Sleeper reactivates, it destroys a seacoast smelting factory and battles Captain America. The Sleeper is ultimately rendered intangible by a "sonic crystal". [2] The Red Skull later activates the Fifth Sleeper, only to have it stopped by Captain America and the Falcon. [3]

The Machinesmith later restores the Fourth Sleeper from its intangible state and uses it to attack Avengers Island and free the robots incarcerated there. It is thwarted by Captain America and badly damaged. [4]

The Fourth Sleeper is later repaired by the Machinesmith and joins the Skeleton Crew in search of the missing Red Skull. It battles the forces of the Hellfire Club and the Black Queen. [5] Replicas of all five Sleeper robots are pitted against Captain America and Diamondback. [6]

Symbiote

The Sleeper symbiote is the child of the Venom symbiote, who intended to care for it after being cleansed by the Klyntar. [7] After learning that it is pregnant with Sleeper, Venom keeps its existence secret from Eddie Brock until they are captured by the Symbiote Task Force, led by Claire Dixonbe and Mac Gargan. [8] Spider-Woman rescues Eddie and Venom, who travel to Alchemax so Venom can give birth. Eddie and Venom entrust Liz Allan to take care of the symbiote. [9] [10] [11]

Sleeper is nurtured and raised by Venom, who regularly visits Alchemax and aims to prevent it from becoming evil. [12] After Venom is taken away by its original host, the Kree soldier Tel-Kar, Sleeper bonds with Eddie Brock and allies with the Warbride Skrull, M'Lanz, to save Venom and prevent Tel-Kar from using a deadly Skrull bioweapon. [13] [14] During the ensuing fight, Tel-Kar is wounded after being caught in an explosion at the Skrull research base. Tel-Kar survives and plans to activate the bioweapon, but is stopped by Sleeper, who lobotomizes him and possesses his body to explore the universe. [15] [16]

In All-New Venom (2025), Sleeper is revealed to have bonded with Rick Jones. [17]

Powers and abilities

The Fourth Sleeper's robotic materials, design, and construction provide it with superhuman physical abilities and limited artificial intelligence. It additionally has optic lasers and could formerly become intangible and generate thermal energy.

The Sleeper symbiote has all of the powers of the predecessor's first human host Spider-Man. It also possesses shapeshifting abilities, which it has used to assume a cat-like disguise. [18] In addition, it is undetectable by Spider-Man's spider-sense and can generate various chemicals. [10] [19]

Video games

The Sleeper robot appears as the final boss of Captain America: Super Soldier . This version is a giant automaton of unknown origin that was discovered during the Middle Ages by Heller Zemo after his ancestor Harbin built Castle Zemo around it. Centuries later, during World War II, Heller's descendant Heinrich Zemo joins forces with Hydra to activate the Sleeper, only to be betrayed by them. Despite succeeding, Captain America destroys it.
