Tooniversary: Pawns of the Kingpin (Spider-Man & His Amazing Friends, 1981)
Spider-Man & His Amazing Friends become "Pawns of the Kingpin" when the web-spinner's long time nemesis hires an enemy of Captain America, Dr. Faustus, to use mind control on Cap and Iceman. Walker Edmiston, a long time voice actor for the Kroffts, voices Kingpin here.
Faustus was not heard from again after this one. Oddly enough, in the comics of the period, Marvel editors had transitioned Kingpin into becoming Daredevil's arch-enemy. Go figure.
