Grima Wormtongue is a supportive antagonist, turned anti-hero, in the J. R. R. Tolkien novella, The Lord of the Rings. The former advisor of King Theoden, Grima Wormtongue revealed his true aspect, serving as Saruman's accomplice, before turning against him as payback for his cruel mistreatment towards him. The Ralph Bakshi's version of the character briefly appeared in the final cutscenes of Heroes vs. Villains War, alongside with Saruman, although it is unknown if he is actually supposed to be presented or if he is only there in the footage used.
Heroes Vs Villains War
Grima Wormtongue briefly appeared, alongside with Saruman, as the wizard stepped forward at Queen Narissa's fountain, ultimately warping himself to the live-action universe. Other than that, he doesn't make another appearance in the tournament.
