When he was 14 years old, Peter Parker was bitten by a spider that had been irradiated in a nuclear experiment. Something in the spider's venom changed him, over night, from the nerdy kid he'd been to something else entirely. Given incredible strength, speed and stamina, he reveled in his power. The tragic death of his uncle threw Peter's good fortune into fierce perspective, giving him direction. From that day on, he vowed to battle evil wherever he could find it as The Amazing SPIDER-MAN.
