The Sleepers are five robots who were created by the Nazis as agents of destruction. They attack various villages in Europe and attempt to destroy the Earth by targeting its core before destroyed by Captain America.[1][2][3]
The Machinesmith later restores one of the Sleepers and uses it to attack Avengers Island and free the robots incarcerated there. It is thwarted by Captain America and badly damaged before being repaired.[4][5][6][7]
Symbiote
The Sleeper symbiote is the child of Venom, who initially keeps its existence secret from Eddie Brock.[8][9][10] The two entrust Liz Allan with caring for Sleeper before it lobotomizes the Kree soldier Tel-Kar and takes over his body to explore the universe.[11][12][13][14][15]
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 limited shapeshifting, camouflage, and a Symbiote's autonomous defense capabilities. In addition, it is undetectable by Spider-Man's spider-sense and possesses chemokinesis.
