The Spider was a member of the newly revived Avengers. The Spider jokingly claimed to be a clone made out of the DNA of both Spider-Man and Prof. Xavier who came from the future "with a warning for humanity," although the veracity of that statement is in doubt. [1]
He was confined in a clear cell and was kept under constant surveillance, suggesting that he was formerly a criminal. He was said to be crazy and has even caused a technician to commit suicide. He enjoyed reading books, which also suggests that he may have been intelligent, as well as insane. Gregory Stark referred to him as "it", suggesting his true nature to be inhuman or especially repulsive.[2]
