[ToyAddict]

I'll preface my comments by saying I think this is a dumb conversation. The world was a much better place when toys, books, games, movies and cartoons intended mostly for CHILDREN were not full of sex. Just plain ol' good triumphing over evil kind of story lines. But to answer the OP:

Baroness was good looking in the cartoon. There's an episode where she's in a bikini. . .

Wonder Woman (Super Friends); or if you'll allow a reach back a little further, Lynda Carter as Wonder Woman

She-Ra

And if my memory serves -- and I know this is reaching into the 90s -- but I always liked Rogue's voice from the X-Men cartoon

maybe some points for Daphne (Scooby Doo)

but the obvious choice:
Jessica Rabbit
