Heidi Klum’s Halloween costume may have leaked The Batman Part II villains

How the costume may have leaked The Batman Part II details

Heidi Klum’s Halloween costume, a severed human hand created by prosthetic company Prosthetic Renaissance, has sparked speculation about potential plot details for The Batman Part II. Prosthetic Renaissance worked on the first The Batman film, and cases labeled “Zsasz,” “Owl 3,” and “Koch” visible in the background of Klum’s costume photo have led to theories about the sequel’s villain roster.

Social media users noticed the labels, which align with DC Comics characters: “Zsasz” refers to Victor Zsasz, a serial killer, while “Owl 3” may hint at the Court of Owls, a secret society of Gotham’s elite. The label “Koch” could refer to actor Sebastian Koch, though his role remains unconfirmed.

Speculation around new and rumored cast roles

Brian Tyree Henry, Sebastian Koch, and Charles Dance were announced as newcomers for The Batman Part II earlier this year, but their roles have not been disclosed. A denture cast visible in Klum’s costume photo resembles Henry, fueling speculation that he may play Two-Face. Another head cast in the photo is suspected to be for Charles Dance, though it is unclear whether he will portray Two-Face’s father or another character.

Sebastian Stan, who was initially rumored to play Two-Face, may instead take on the role of Victor Zsasz. The “Zsasz” label on the prosthetic cases aligns with this theory, though neither Warner Bros. nor the film’s team has confirmed any casting details.

The Court of Owls and its potential role in the film

The Court of Owls, a secret society introduced in Scott Snyder and Greg Capullo’s 2011 comic run, has never appeared in a live-action DC adaptation. The group controls Gotham from the shadows, using immortal warriors called Talons. While the Court has appeared in animated movies and the 2022 Gotham Knights game, its inclusion in The Batman Part II would mark its first live-action debut.

Director Matt Reeves has not confirmed plans to feature the Court of Owls, but the “Owl 3” label on the prosthetic cases has reignited fan theories. If the group does appear, it could set up a larger narrative arc for future DC films.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

For founders and operators in the entertainment and film production sectors, this leak—whether intentional or accidental—highlights the risks and opportunities of early-stage marketing. Prosthetic companies working on high-profile projects often operate under strict nondisclosure agreements, yet their work can inadvertently reveal key details to audiences. This incident underscores how even tangential partners, like costume or prosthetic suppliers, can influence fan expectations and shape a film’s pre-release narrative.

For startups in the entertainment tech or content creation space, this also serves as a reminder of the scrutiny that accompanies franchise adaptations. Fan communities dissect every detail, from casting choices to production design, which can amplify both engagement and backlash. Studios may need to balance secrecy with controlled leaks to maintain momentum without spoiling major plot points.
