The Spectacular Spider-Man #64 (1982)
By Bill Mantlo, Ed Hannigan, Jim Mooney
So, What Happens? During a night patrol, Spider-Man meets Simon Marshall, a terrified former pharmacist turned drug maker on the run from two mysterious costumed youths named Cloak and Dagger. Spidey tries to stop them, but Cloak's cape is the entrance for a dark, freezing empty space, while Dagger can create light blades with which she kills Marshall. Eventually free of Cloak's trap, Spider-Man tries to at least capture them, but they are good enough to evade him until Dagger's mentally-controlled blade hits Spidey, leaving him shaken and cold. However, the couple don't want to harm him and teleport away thanks to Cloak's cape. Just about making it home, Spidey recovers overnight and the following day goes to the Bugle looking for information about Marshall, Cloak and Dagger. He is told that Marshall was based on Ellis Island, where the mob tested his experimental new drug on unaware runaway kids, leaving a basement full of bodies. Later that evening, Spider-Man goes to Ellis Island to check for himself, finding Cloak and Dagger who have cornered a number of people responsible for their condition. They reveal that they were young runaways who were injected with Marshall's experimental drug, which, instead of killing them like the other kids, activated their powers. Despite understanding their motives, Spider-Man believes the criminals should be handled by the justice system and tries to stop Cloak and Dagger from killing them in cold blood. Spidey is now starting to figure out their powers, but when the mobsters manage to take Dagger hostage, Cloak takes matters into his own hands and uses his darkness to make them all run out of a window and plummet to their deaths. Having nothing against Spider-Man, Cloak and Dagger then teleport away, but not before warning him that their war on crime isn't over.
