Okay, so I'm actually imagining actors talking in their normal voices, not voice actors who literally voice act. Haha.
Bubbles:
Erica Durance
Olivia Munn
Okay, I am having difficulty coming up with more actresses who could voice Brun. She definitely doesn't have a squeaky, girly, cutesy voice, in my mind.
Dora: someone said Mary Elizabeth McGlynn. How about Mary Elizabeth Winstead, instead? : p
Tai: this is kind of a tough one...hmmm...maybe it's just because I just watched SNL but Aidy Bryant comes into my head. I think it could work.
Now I'm going to read all the comics using their voices in my head and seeing how it works. I am sticking with Britt Robertson for Faye.
