Amazing Spider-Man #138 (1974)
Upon leaving the orphanage, William sought a secluded spot where he could drain emotions from his neighbors without being detected. Now calling himself the Mindworm, William chose an abandoned home in Far Rockaway and leeched nourishment off the community for years - drawing residents, zombie-like, around his home. But Peter Parker's visit to Flash Thompson's apartment alerted Spider-Man to Mindworm's presence. With Spider-Man resistant to his mental powers, Mindworm resorted to using a crushing bear hug, but his comments about "hearing" Spidey's mind prompted the web-slinger to clap his hands over Mindworm's ears, severing his link with his victims. Feeling devastatingly alone, Mindworm was taken into custody by the police.
Denied the emotional nourishment of others' minds, Mindworm was hospitalized. Though appearing comatose he actually was working to focus his mental strength to gain revenge on Spider-Man from a distance. Instead, he had a dream that was so psychically potent it drew the sleeping Peter Parker inside it as well. With the wall-crawler's help, Mindworm realized that his feelings stemmed from his guilt over his parents' deaths. Now understanding his anguish, he regained the use of his body and turned his back on his vampiric past. Unfortunately, William slipped into robbery and, caught by Spider-Man, was sent to Ravencroft and later the Cage, where he was nearly set free by the Rhino. Out of prison and mentally ill, William took to alcohol and lived on the streets where Spider-Man found him telepathically broadcasting his misery throughout an entire city block. Unsure of how to help, Spider-Man delayed too long while William was murdered by some street thugs.
