Is the female super hero the same person who voices Juliet in Lollipop Chainsaw?

Yep, it's Tara Strong alright. IMDB doesn't have data for W101 yet but this link gives the info for the four main heroes:

I had initially thought that Wonder Red was voiced by Dee Bradley Baker, the voice of Viewtiful Joe, but apparently not.
