Number 9 in my Devil's Due customs
A very standard version of the character, with my third use of the Baroness torso (result of limited numbers of female parts; I'm trying to get hold of Bombstrike, but it's pretty tough in the UK), and the Baroness/Scarlett hair/head combination that's been used before. I know it's not very original, but it works too well to ignore.
My only real concession to originality is the use of the Alley Viper legs; the downside is that they do make her a bit bandy-legged, but I still think it works reasonably well.
