Summary: The Secret Six is a collection of super villains who live in the the edgy world of mercenaries where violence and chaos are the norm for their methods. However, under the hand of fan-fav writer Gail Simone, they are also individuals who wrestle with friendships, family and where doing the "right thing" has a different standard.
Review: Thanks to re-discovering comics via Comixology, I followed up on references to a lesbian couple that was supposed to be featured prominently in the two versions of this series. And found one of my favorite lesbian couples in comic book-dom in the form of Scandal Savage and Knockout. Sexy, dangerous and completely devoted to each other.
NOTE: If you do check them out, you need to read the 6 issue "Secret Six" first, then a story-arc written by Simone in Birds of Prey featuring a Secret Six cross-over, and then the final "Secret Six" series.
And the stripper with a heart of gold Lianna, is also another lesbian character who is valid in her own right.
Now, unfortunately, since the latest DC reboot of "The New 52", these characters not not yet appeared so it's still up in the air if they exist in the new continuity. Fingers crossed that someone (talented) will bring them back.
