DC makes a huge change to Clayface‘s identity right as the Batman villain becomes a cinematic phenomenon. In DC Comics lore, the mantle of Clayface has passed through eight different individuals, each with wildly different origins, personalities, and biological mutations. The original Golden Age villain, Basil Karlo, debuted as a bitter horror actor who wore a clay mask to murder the cast of a remake before injecting himself with the DNA of his successors to become “Ultimate Clayface.” Matt Hagen, the Silver Age treasure hunter, introduced the iconic shapeshifting mud-monster template after bathing in a radioactive pool of protoplasm.
In James Watkins’s 2026 body-horror movie Clayface, DC Studios streamlined the titular Gotham villain’s convoluted comic history into a single origin story centered on Tom Rhys Harries’ Matt Hagen. Much like the acclaimed Batman: The Animated Series episode “Feat of Clay,” the DCU’s Clayface movie merges Matt Hagen’s name and iconic mud-monster powers with Basil Karlo’s signature background as an ambitious actor obsessed with his appearance and craft. Instead of stumbling upon a mystical cave pool, the DCU’s Clayface mutation also updates the nature of Matt Hagen’s transformation with modern AI nanobots that feed on his emotions.
Batman and Gotham’s other vigilantes still have to deal with the existence of multiple Clayfaces in the comics, though movie-comic synergy might help them simplify their shapeshifting threat.
DC’s Two Main Clayfaces Matt Hagen And Basil Karlo Are Now One And The Same

In Jude Ellison S. Doyle and Fran Galán’s Clayface: Celebrity Dirt #5, DC officially fuses its two most iconic Clayfaces into a single person, confirming that Matt Hagen and Basil Karlo are the same person on a genetic level. Throughout the series, Preston Payne, the third Clayface, steals the “Basil Karlo” identity for himself, leaving the original monster trapped in an identity crisis. When Dr. Victoria October investigates the shapeshifter, she discovers that years of reckless cellular tampering and constant shapeshifting have scrambled his DNA so severely that Matt Hagen and Basil Karlo are indistinguishable at the molecular scale.
Petty criminal Matt Hagen and Hollywood actor Basil Karlo are no longer two separate men with separate histories. By this point, they have physically and genetically collapsed into one being. This permanent DNA merger brings decades of tangled comic book continuity into alignment with Batman: The Animated Series and the 2026 Clayface movie. Hagen and Karlo’s fusion into a single genetic identity removes the divide between the original two Clayfaces from Batman lore and enhances the body-horror tragedy at the core of the character, as Matt Hagen and Basil Karlo’s overpowered shapeshifting ability comes at the great cost of their identity.
Clayface: Celebrity Dirt’s Fusion Has Already Happened Elsewhere In The Comics
Absolute Batman Introduced A Definitive Clayface A Couple Months Before
The fusion revealed in Clayface: Celebrity Dirt actually echoes a grotesque precedent set a couple of months earlier in Scott Snyder and Nick Dragotta’s Absolute Batman #22 and #23. The Absolute Universe’s definitive Clayface is born inside Ark M’s “Project K.L.A.Y.” as a horrific biological amalgamation of multiple human victims melted together into one mass of living protoplasm. Led by the consciousness of sculptor Basil Karlo, this monstrous entity physically absorbs human beings into its mud-like body and traps their fragmented minds inside a single hive-mind.
While Absolute Batman turns that multi-person amalgamation into a nightmare of body horror for an increasingly busy Bruce Wayne, Clayface: Celebrity Dirt brings a more tragic twist to its Basil Karlo-Matt Hagen fusion, who genuinely wishes to recover some semblance of a regular life. Both stories arrive at the exact same unsettling conclusion from different angles. The truest, most terrifying form of Clayface is an unstable composite where multiple identities have fused together until the original self is lost forever. The difference is how each Clayface reacts to their loss of identity.
