Peter Milligan’s return to one of his strangest creations in the All-New Doop miniseries has proven just as weird as expected, inserting the green, potato-esque X-Man into last year’s “Battle Of The Atom” crossover for an absurd, meta-textual character study. Teaming with artist David Lafuente (with assists by Jacopo Camagni and Federico Santagati) and colorist Laura Allred, Milligan has taken readers on a madcap journey through the margins of a major comic-book event, and the cliffhanger of last month’s issue took an especially wild turn when Doop met his mother.
