The only child of Richard and Mary Parker, Peter Parker was orphaned at the age of six when his parents were killed while overseas on goverment business. Peter was left in the care of his eldery uncle and aunt, Ben Parker and May Parker, who unhesitantingly raised him as they child they never had. Peter was academiccaly gifted, and he displayed an uncanny affinity for science that was nothing short of genius. Socially, however, he was painfully shy and the target of much cruelty. His uncle and his aunt compensated with a steadfast love, but they worried privately what lay in store for a fragile boy. At Midtown High School, Peter attended a public evening exhibition demonstrating the safe handling of nuclear laboratory waste materials. A spider, accidentally irradiated by a particle beam, fell on Peter's hand and bit him.From that day on Peter Parker obtained his powers to later become the amazing Spider-Man!
