Spider-Man (Peter Parker)[src]


A spider got caught in a radiation test at a public exhibition demonstrating the safe handling of nuclear laboratory waste materials, sponsored by the General Techtronics Corporation. The radiation, however, was slowly killing it. Before it died it bit a student from Midtown High named of Peter Parker. The spider's venom caused changes to Peter's DNA that gave him certain abilities of a spider, such as the proportionate strength and agility along with the ability to climb on any surface. He could now react to danger quickly with a "spider-sense".[9]

The spider also had time to bite another person following Peter: Cindy Moon, who got the same abilities as Spider-Man. She later took up the identity of Silk.[10]

A student by the name of Carl King, who witnessed Peter being bitten and connected it with the appearance of Spider-Man, ate the spider hoping to gain the same powers of Spider-Man. His body began to break down over time, mutating him into a swarm of thousand spiders sharing a single consciousness.[11]

Lord Chaos and Master Order once claimed credit for having orchestrated the events that led to Peter Parker becoming Spider-Man, having "chosen" that destiny for Parker in the belief that his nobility and "strong heart" would one day prove vital in a battle against Thanos.[12]

Years later, Ezekiel Sims told Peter that the spider that bit him was not merely radioactive, but an embodiment of a totemic spider deity that had chosen him as its avatar. While Peter was skeptical of this alternate origin story, he came to accept that they were not mutually exclusive.[13]

When Spider-Man's soul was captured by the Arachnix, a race of demonic arachnids, and brought to their realm, it was revealed that the spider hatched from one of their eggs, which had been smuggled to Earth by the sorcerer Driddil.[14] The spider's spirit, which had been entwined with Spider-Man's since her death, attempted to forcibly merge with Spider-Man's soul to become something greater, but she was prevented from doing so by Doctor Strange, who vanquished her with M'Matrixx's wand.[15]

Due to having been turned into a Gamma mutate, the spider resurrected, attaining sentience and the ability to speak due to having been affected by Peter and Cindy's human DNA. The radiation emitted by the Isotope Genome Accelerator also caused her to split in two, with her clone being the spider that was eaten by Carl King. Capable of increasing her size to massive proportions, she was inspired by Spider-Man and Silk and set out to become a superhero under the name "Goddess" - which had been given to her by a researcher studying her.[8]

Radioactive Spider (Earth-65) 001.jpg On Earth-65, two radioactive spiders existed. The first arose as a result of a science experiment and nearly bit Cindy Moon, but was killed before it could do so.[17] The second was created by Moon with the intent of recapturing that moment; based on her research into the mutagenic venom of extraterrestrial spider-like aliens. Reluctant to use it on herself, she instead released it into the wild - where it bit Gwen Stacy.[18] Spider-Gwen (Vol. 2) #19

After Peter lost his powers, the spider was used to give them back, however over the years he had build an immunity to its venom. As he tries to find a way to bypass it, Peter discovers an anomaly in his DNA, finding rare variants in it that what allowed him to not only survive the radiated venom, but also gain the abilities of a spider.[23] Ultimate Spider-Man (animated series) Season 1 1
