Venom (Klyntar) (Earth-1600)

The Venom Symbiote is an alien parasitic creature who bonds with a host in order to survive. It is the sole survivor of its species after life in its homeworld was dying out. After landing on Earth through transport in the space shuttle, it was found by OsCorp scientists and was experimented on. One of the scientists, Edward Brock Sr., discovered that the "suit" can be a source in curing various diseases, but he died in a plane crash before he could prove this. The suit was later handed over to Otto Octavius and was fused with Spider-Man's DNA, giving it a higher level of intelligence and even making it more powerful to control its host.

Trivia
