The closed alpha test for Invincible VS, the upcoming 3v3 superhero fighting game, has given players more than just early gameplay access. Through a model swap bug discovered during testing, dataminers have uncovered an unrevealed character hiding in the game files: Anissa, one of the most controversial figures from the Invincible universe.
Alpha Test Reveals Hidden Character
The closed alpha test for Invincible VS kicked off on November 21, 2025, running until November 24 for select PlayStation 5 and Xbox Series X/S players. Unlike many alpha tests, this one came without a non-disclosure agreement, allowing participants to freely share their experiences and discoveries online.
During gameplay, testers encountered a technical glitch that caused character models to swap unexpectedly. This bug exposed underlying game files that contained character data for Anissa, a Viltrumite warrior who hasn’t been officially announced as part of the playable roster. The discovery quickly spread across gaming communities, with fans reacting to both the technical slip and the character choice itself.
Who is Anissa?
Anissa is a complex and divisive character from the Invincible comic series created by Robert Kirkman. She is a pure-blooded Viltrumite warrior, thousands of years old, who serves as a fiercely loyal enforcer of the Viltrum Empire. Like other members of her species, Anissa possesses superhuman strength, speed, durability, and the ability to fly.
What makes Anissa particularly controversial is her role in the comics as an antagonist who commits heinous acts in service of the Viltrumite cause. She embodies the cold, utilitarian values of her people, prioritizing efficiency and the expansion of the empire above all else. Her character arc includes some of the darkest moments in the Invincible series, making her one of the most polarizing figures in the franchise.
In the story, Anissa attempts to convince Mark Grayson (Invincible) to join the Viltrumite cause by pointing out humanity’s failings. When persuasion fails, she resorts to violence and manipulation, cementing her status as a memorable villain in the series.
Current Roster and Game Details
Before the Anissa leak, Invincible VS had officially confirmed 11 playable characters for its roster. The lineup includes fan favorites like Invincible, Omni-Man, Atom Eve, Rex Splode, Bulletproof, Battle Beast, Lucan, Thula, Cecil Stedman, Robot, and Monster Girl. The game’s creator, Robert Kirkman, has promised an “absolutely insane” roster, suggesting that if fans can think of an Invincible character, they’ll likely be in the game.
The development team expects to launch with between 15 and 20 characters, meaning several more announcements are coming before the game’s 2026 release. The addition of Anissa, while leaked rather than revealed, fits the pattern of including multiple Viltrumites in the roster to represent the empire’s military might.
Development Team and Release Plans
Invincible VS is being developed by Quarter Up, a newly formed studio led by former members of the core Killer Instinct (2013) development team. The studio was established as Skybound Entertainment’s first in-house video game division, specifically created to produce fighting games for the competitive gaming community.
The game features a brutal 3v3 tag team fighting system where players can assemble teams of characters and battle across iconic locations from the Invincible universe. It includes single-player story mode, online PvP, and co-op modes. The narrative mode is designed to function like an extended episode of the animated series, featuring every announced character and introducing elements unique to the game.
Invincible VS is scheduled to release in 2026 for PlayStation 5, Xbox Series X/S, and PC via Steam. The game will be available as an Xbox Play Anywhere title and is already available for wishlisting on various platforms.
Community Reaction to the Leak
The gaming community’s response to the Anissa leak has been mixed but largely intrigued. On Reddit’s GamingLeaksAndRumours subreddit, where the discovery was first widely shared, players expressed both excitement and apprehension about the character’s inclusion. Many fans noted that interactions between Anissa and characters like Invincible and Omni-Man would be “quite uncomfortable” given their complicated history in the source material.
Some players have voiced a desire for more diverse character types beyond Viltrumites, suggesting quirky characters like Allen the Alien or Shapesmith to balance the roster. However, others appreciate the inclusion of complex antagonists that add depth to the game’s narrative potential and provide varied fighting styles for competitive play.
What This Means for Future Reveals
The accidental leak of Anissa suggests that Quarter Up has been working on a larger roster than publicly announced. The presence of complete character models in the alpha test files indicates that development on unannounced fighters is well underway. This aligns with Kirkman’s promises of an extensive character selection at launch.
With the closed alpha test wrapping up on November 24, the development team will likely analyze feedback from participants to refine gameplay mechanics, balance characters, and fix technical issues like the model swap bug that led to this leak. Official character reveals are expected to continue in the months leading up to the 2026 release, potentially including proper trailers for Anissa and other hidden fighters.
