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".
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.
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.
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.
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. 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.
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.
