Doctor Who: A Marvel Monthly #58

"Junkyard Demon [Part 1]" kicks off with a tense U.N.I.T. Skywatch-7 alert as a suspected meteorite impact draws attention. When a soldier sent to investigate returns, his unsettling behavior raises alarms—only for the team to realize too late that he’s no longer human, but a Zygon in disguise. Written by Maxwell Stockbridge and illustrated by Mick Austin, with inks by Austin and letters by Elitta Fell, this 1981 UK Marvel monthly delivers a chilling first chapter in a classic alien infiltration tale.
