Based on the leak, it appears that Batman’s most notorious villains will continue to appear in Lego Batman: Legacy of the Dark Knight.

Lego Batman: Legacy of the Dark Knight is the latest DC game and has been a massive critical success for publisher WB Games and developer TT Games. A new leak from X0X_LEAK on Twitter reveals the DLCs that Warner and TT Games (or Traveller’s Tales) are preparing for the new Lego adventure.

Unsurprisingly, the next dozen DLC characters delve deeper into the vast roster of Batman villains. Of course, this should be taken with a grain of salt. Still, it’s exciting to know that major Batman characters like Deathstroke, Deadshot, and Killer Croc may potentially join Lego Batman: Legacy of the Dark Knight in the future.

The Lego Batman Mayhem DLC will feature the following Task Force X members: Bronze Tiger, Captain Boomerang, Deadshot, Deathstroke, Javelin, Katana, Killer Croc, King Shark, Lester (the Electrocutioner?), Mongal, Polka-Dot Man, Rick Flag, A.R.G.U.S., and Cops (presumably members of the Gotham City Police Department). Joker and Harley will also be available as ally characters.

WB and TT Games are clearly lining up multiple DLC characters for Lego Batman: Legacy of the Dark Knight, as it was obvious before the game’s release that it would be a hit. Earlier this year, it was one of our most anticipated platformers for 2026. We must point out that games in this genre are few and far between, especially high-quality ones. If it were two decades earlier, there would be plenty of such titles, but the world has changed since then – and we have too.

Only time will tell how long we’ll have to wait for Warner and TT Games to confirm that Lego Batman: Legacy of the Dark Knight will feature these characters.
