Spider-Man: Edge of Time and X-Men: Destiny have been signing up some recognizable voices, including Val Kilmer and Heroes' Milo Ventimiglia.
Kilmer will voice bad guy Walker Sloan in the Spider-Man crossover, as the traditional Spider-Man meets his futuristic equivalent from 2099.
Joining him will be Laura Vandervoort ( Smallville, V) as love interest Mary Jane and Katee Sackhoff ( Battlestar Galactica, 24) as old flame and fellow vigilante Black Cat.
Ventimiglia is voicing one of X-Men: Destiny's new class of superhero mutants, as are Jamie Chung ( The Hangover Pt 2, Sucker Punch) and Scott Porter ( Friday Night Lights, The Good Wife).
Both games are due out later this year, and are to make an appearance during San Diego Comic-Con, July 21-24.
Batman, played by Val Kilmer in 1995's Batman Forever, returns to PC, PlayStation 3 and Xbox 360 in October's Batman: Arkham City.
