Madelyne Pryor
Madelyne Pryor was introduced during the acclaimed 1983 "Uncanny X-Men" run that saw long-time writer Chris Claremont pair with artist Paul Smith for a series of issues that would see the Jean Grey look-alike marry the retired X-Men leader Scott Summers (Cyclops).
Cloak and Dagger (comics)
Cloak and Dagger first appeared in "Peter Parker, the Spectacular Spider-Man" #64 (March 1982). After a number of additional Spider-Man guest appearances, they were given their own four-issue limited series, written by creator Bill Mantlo, penciled by Rick Leonardi, and inked by Terry Austin. It debuted in October 1983 and was a success, prompting Marvel Comics to launch an ongoing bi-monthly Cloak and Dagger series in 1985, with the same creative team. Costumed supervillains rarely appeared in the series, which focused on Cloak and Dagger's quest to end the drug trade completely, and frequently explored the issue of vigilantism. Leonardi left after issue #6 and was replaced by a series of fill-in pencillers.
