Batman #28

In "De modder bende deel drie: Dodelijk leem," Batman is trapped by a coalition of Clayfaces—Karlo, Payne, Fuller, and the lingering presence of Hagen—as they force him to confront a barrage of his deepest fears. Among the visions, he faces nightmare images of Calendar Man, Dr. Phosphorous, Cluemaster, Killer Moth, Catman, Scarface, and the Ventriloquist, while the real threat of Doctor Lowell looms. Meanwhile, Looker works in the shadows, determined to find Batman before the Clayfaces’ scheme reaches its climax.

In "De modder bende deel vier: Clayface in optima forma," Batman is rescued by Looker as Basil Karlo, driven by obsession, forces the late Doctor Lowell’s blood samples—stolen from Preston Payne and Sondra Fuller—into a new, terrifying fusion. With the experiment underway, Karlo transforms into a monstrous amalgam of his rivals, while Payne and Fuller, now free, discover an unexpected connection amid their shared chaos.
