I usually don't bite for FABs, I'm just not a big fan of them, but I picked up Screamer for my SS collection and I love this guy. Will post some pics soon as I can, but for one, he's not brown, he's grey, which is awesome. He has a neat purple blade that pops out and you can leave him mid transformed with his robot legs poking straight down for some japanese robo plane with legs action. Not sure what they're called, robotech I believe?
I have a very small interest in him, but I'd rather get the Ramjet repaint from the first movie line.
