Carl King was a life-long bully, especially to Peter Parker. From Kindergarten through High School, Carl would pick on the young bookworm. Carl was also a witness to Peter getting bitten by the radio-active spider that gave him his spider-powers that eventful day at the Nuclear Physics Exhibition while on a class trip from Midtown High School. Carl then followed Peter home that same day and was aware of the events leading up to Peter taking the costumed identity of Spider-Man. Carl wanted it to be him and always thought that it should have been him with the powers instead of Peter so he ate the dead radio-active spider that gave Peter his powers and he became literally a thousand spiders, killed his parents and went on to kill many more. In the end though, he was electrocuted while fighting Spider-Man killing every spider but one, but that one little spider soon felt the bottom of a man's shoe while accidentally stepped on.
