Injustice 3 leaks: 2026 Character Rumors & Evidence

The current Injustice 3 leaks conversation centers on two rumored playable characters: Supergirl and Batwoman. A September 22, 2026 report from IGN described evidence connected to both characters, while also stressing that Warner Bros. and NetherRealm Studios have not officially announced the game.

Supergirl would be a familiar choice because she was playable in Injustice 2. Batwoman would be a newer addition to the mainline fighting-game roster, although her reported inclusion creates story questions because Kate Kane dies in the established Injustice comics timeline.

Video Highlights:

• Ed Boon responded to a parody rumor involving NetherRealm Studios and Insomniac.
• The response fueled debate about whether he was indirectly addressing Injustice 3 speculation.
• Previous NetherRealm rumor cycles show why social-media posts should not be treated as confirmation.
• Playtest claims, résumé references, and voice-acting reports remain unverified.

The most reliable way to read the current rumor cycle is to divide claims into evidence levels rather than treating every repeated post as a separate leak.

The two most prominent character rumors are Supergirl and Batwoman, but they should not be treated equally in terms of continuity. Supergirl already has a clear place in the game series. She appeared as a playable fighter in Injustice 2, where her Kryptonian abilities made her one of the franchise’s most recognizable characters.

Batwoman is more complicated. In the comic continuity referenced by current reporting, Kate Kane dies. That leaves several possible explanations for a playable Batwoman in a future title:

• The story could introduce another character using the Batwoman identity.
• Kate Kane’s death could be revised or ignored.
• The game could continue a different branch of the timeline.
• Injustice 3 could function as a reboot with a new continuity.
• The report could be inaccurate or based on an early development concept.

The reported roster information is useful because it suggests that development discussions may include both returning favorites and characters making their mainline debut. However, it does not establish the final roster. Fighting games frequently change their character lineups during production, and early concepts may never reach release.

The wider Injustice 3 rumor cycle includes reported voice-acting comments, résumé references, and a claimed playtest. These details may appear more substantial than anonymous social posts, but each has limitations.

A résumé can point to work associated with a project without proving that the game will be announced soon. Voice actors may work on tests, temporary material, or projects that change direction. A playtest claim is also difficult to verify unless participants provide consistent details that can be independently checked.

Ed Boon’s reported response adds another layer. He rejected a parody claim that NetherRealm was partnering with Insomniac on a new fighting game. That reply confirms the parody partnership was false, but it does not directly verify or disprove Injustice 3.

The safest editorial verdict is that Injustice 3 remains a highly discussed but officially unannounced project. The evidence is strong enough to justify tracking the rumors, but not strong enough to present a release window, final roster, or story premise as fact.

December 2026 has become a popular prediction window because major gaming announcements often receive attention during year-end showcases. However, an expected event is not the same as a scheduled reveal. No confirmed announcement date or release date is available for Injustice 3.

The most responsible forecast keeps three possibilities open:

1. NetherRealm may reveal Injustice 3 after its current development priorities become clearer.
2. The studio may announce another project first, including a future Mortal Kombat title.
3. The reported project may be delayed, reworked, or not publicly released in the form described by current leaks.

The long gap since Injustice 2 creates understandable interest, but the delay also makes a reboot or continuity reset plausible. A new entry could continue the existing timeline, adapt a different comic direction, or rebuild the premise for a new generation of players.

The next meaningful update would be an official announcement, not another interpretation of a cryptic social-media post. A reveal trailer, developer interview, store listing, rating-board entry, or publisher presentation would provide clearer evidence than current rumor fragments.

Fans tracking the project should focus on concrete details:

• The official title and development studio.
• Whether the game is a sequel, reboot, or separate continuity.
• The first confirmed characters and gameplay footage.
• Platform information, which is not currently established.
• A release window supported by Warner Bros. or NetherRealm.
• Whether the reported Batwoman story is addressed directly.

The current character rumors are interesting because they point toward a possible blend of returning heroes and new mainline fighters. They are not enough to establish the final design of the game. Until more information appears, the best prediction is simply that the project remains under discussion and that its public status could change quickly.
