Mark Hamill didn't voice the Joker in Injustice: Gods Among Us. Despite widespread rumors and fan assumptions linking the legendary actor to every major DC video game project, Richard Epcar voiced the Clown Prince of Crime in the 2013 fighting game developed by NetherRealm Studios.
If you've played through the story mode and thought you recognized Hamill's signature cackle, you're not alone. The confusion stems from Epcar's deliberate homage to Hamill's iconic vocal styling, paired with Hamill's extensive history voicing the character across animated series and the Batman: Arkham game trilogy.
Who Actually Voiced the Joker in Injustice?
Richard Epcar took on the role of the Joker for Injustice: Gods Among Us and its 2017 sequel, Injustice 2. Epcar is a veteran voice actor with hundreds of anime and video game credits, including Batou in Ghost in the Shell and Ansem in Kingdom Hearts.
When NetherRealm Studios cast Epcar, they wanted a darker, more visceral tone that matched the game's brutal alternate-universe storyline, where Superman establishes a global totalitarian regime after the Joker tricks him into killing Lois Lane. Epcar delivered a raspy, unhinged performance that leaned heavily into the psychological terror of the character. Because fans spent years associating the Joker's manic laugh and high-pitched shrieks with Hamill's landmark work in Batman: The Animated Series, Epcar's similar cadence easily fooled casual listeners.
The Mark Hamill DC Video Game Connection
It's easy to see why players mix up the voice cast. Mark Hamill defined the modern auditory experience of the Joker starting in 1992 and reprised the role in critically acclaimed titles like Batman: Arkham Asylum and Batman: Arkham City.
However, NetherRealm Studios (formerly Midway Games Chicago, creators of Mortal Kombat) assembled their own distinct voice cast for the Injustice franchise. They brought in high-profile talent for other roles—such as George Newbern as Superman and Kevin Conroy as Batman—but cast fresh or alternative talent for specific legacy roles to fit their specific narrative direction.
Complete Injustice Voice Cast Breakdown
To clear up any further confusion about who lent their talent to the roster, here's how the principal cast shakes out:
- Batman: Kevin Conroy
- Superman: George Newbern
- Wonder Woman: Susan Eisenberg
- The Joker: Richard Epcar
- Harley Quinn: Tara Strong
- Lex Luthor: Mark Rolston
- The Flash: Neal McDonough
While Kevin Conroy and several other Justice League staples returned from the classic animated universe, the Joker went to Epcar.
Common Mistakes and Fan Confusion
Many gaming forums and older wikis get this wrong because of overlapping release windows. Injustice: Gods Among Us launched in April 2013. Just a few months later, Rocksteady Studios and Warner Bros. Games were deep in production on Batman: Arkham Origins (released in late 2013), where Troy Baker voiced a younger Joker, though Hamill returned later for Batman: Arkham Knight in 2015. With multiple Joker voice actors working on major DC properties within a tight three-year span, misattributions became standard across the internet.
