So I'm writing this take mostly for @Zorax. I had already written a take about male butts, and he was interested in seeing one about legs. I'm probably not the best person when it comes to rating women's legs, but here goes...
10. Poison Ivy
9. Spider-Woman (Jessica Drew)
7. Power Girl
I guess her boobs aren't the only thing she's known for.
5. Big Barda
And if you wanted to see them without the armor, here you go.
4. Scarlet Witch
3. Wonder Woman
2. Black Canary
It was obvious that she was going to come out on top. Majority of the panels featuring her focus on her legs.
I think Serinda Swan pulled off the look really well in Smallville.
