Since I didn't need a female Siren, and I wanted to find a use for the additional feminine chestplate I dug through the obsure character Archives. Roulette is named after an OTFCC exclusive, yet has the color-scheme of her set-mate Shadow-Striker (since Roulette was just a better name for a female Decepticon). Repainted the Goldfire head since it already shared many similarities with her OTFCC toy head, her Guns came from TomB's shapeways store.
thanks, no plans for her mold-mate, this is my last outing for the BB mold, until carzap anyway ( Crap that will officially make this the most common body type in my collection, actually outnumbering my seekers! That's nightbeat, Minerva, Windcharger Tailgate, Siren, Goshooter, Wipe-out, Decepticharge, and now Roulette!) So unless Johnbonhamatron frees some time for new chest plates them I'm all done with this mold once Carzap is released. Thanks guys!
According to Glen Hallit, Shadow Striker's name was originally intended to be "Silhouette" - Tfwiki.net
