I think it's strange that they never made a Sigma 6 action figure of Scarlett... I'm guessing it was because of one of the following:
A) They didn't want to bother making another action figure where they couldn't re-use any parts
B) They simply didn't think there would be a market for a female Sigma 6 figure
C) They feared parents would complain when they walked into little Johnny's room and found him doing with Snake-Eyes and Scarlett what Dad used to do with GI Joe and Barbie.
Oh well, whatever the case, it didn't happen, and now the Sigma 6 line is disappearing-- likely to be replaced next summer with the GI Joe movie-inspired lineup. But hey, at least someone put together this cool custom.
Sigma 6 was great. I really hope they finally put out the whole thing on DVD, so far I have the Sigma 6 movie which is just the first 3 episodes edited together. It's a show that really needs to return to TV though, some of those battles were damn epic.
