Peter Porker was born as a spider (simply called Peter). He resided in the basement laboratory of May Porker, a somewhat clumsy animal scientist who had created the "world's first atomic energy hair dryer," hoping that "the introduction of nuclear fusion in beauty salons of the United States "could" revolutionize the hair care industry. " After spraying her head with water and activating the dryer, May Porker accidentally irradiated herself, and in a fit of delirium, bit Peter, who was later transformed into an anthropomorphic pig very similar to May Porker herself. Fleeing from the disoriented Porker farm, Peter soon realized that he still retained the skills of a spider:

"This is amazing! Am I a spider with the limitations of a pig? Or a pig with the strength and agility provided by a spider? I have become something bigger than a spider or a pig ... I have become Spider-Ham! "
