I don't know why, but when I was a kid, I liked the idea of each Joe having a Cobra that they were matched up against. (Much like Snake Eyes was to Storm Shadow.)
And for some reason, I decided that Firefly's counterpart was Beach Head. I think I just liked that they were both masked bad-asses.
Heroclix Bane Thug came out. It had everything I needed except the mask which, I suddenly realized, I could just paint it on.
And it worked...and quite well I must say.
