According to IMDB – where everyone can add randomly any information – Alicia’s gonna lend her voice to She-Hulk in “Marvel vs. Capcom 3: Fate of Two Worlds”. She dubbed She-Hulk in the video game “Marvel: Ultimate Alliance 2” so that isn’t unlikely, BUT according to other sources, the actress Maria Canals Barrera will lend She-Hulk her voice.
So, I can neither confirm nor negate this information so far. Personally I tend to not believe the rumour that Alicia dubbed this character for M. vs. C. 3.
I’ll let you know as soon as I find an official confirmation.
