As for the voice, imagine Olivia Olson attempting to do a British accent and you'll get the idea (which to bring up another character she voiced...and as a IRL dude...would've made Marceline even sexier than she was already.)
Okay, got an image (that I colored myself) that give an idea how Vanessa looks, essentially, Vanessa Doofenshmirtz with Ferb's color scheme. (Sorry the color job isn't great)
Slight alteration to the idea, Vanessa Doofenshmirtz still exists, Ferb was just made into a copy of her due to an accident with one of Heinz's -inators, and feeling bad that one of their missions caused it, the newly renamed Vanessa Fletcher, works as an intern at OWCA now.
@MMLginger Thanks, still getting used to being this way. I mean, when you and I first met, I was still...Ferb. Anyway, trying to figure out what to go as for Halloween.
Should explain the concept behind this profile, an accident put Ferb into Vanessa's body and things were worked out to allow her to live with her family (the Flynn-Fletcher one, not Doofenschmirtz one) and her parents do believe she is who she says is...due to proof.
To anybody I RP with, while I can't change the profile pic yet or edit the profile yet. From now on, Vanessa will have foam green hair, she dyed it to look a bit like her old self and stand out from other Vanessa's out there.
