It actually all started this past summer when I found an old Star Wars rip off action figure case that I'd been remembering from childhood but never owned until recently:
Fast forward to present day and I'm hunting down some of the more zany, vintage metal minis from Gamma World, Star Frontiers, and other off-brand sci-fi lines. I've been having fun coming up with bios based on them.
Here's what I've worked up so far:
Xarth Raiden4-LOM and Zuckuss (and who hasn't really?) and swapped their names on the action figure cardbacks. Basically, Xarth is a recasting of Vader using both bounty hunters. He's an insectoid, alien, warlock, more cold and calculating than the Sith Lord ever was. His environment suit is a hefty upgrade over the "prison" Anakin Skywalker endured. Xarth's threads are customized cyborg implants with all manner of sensors to amplify his inherited insect abilities and learned psionic talents.
Apologies for the craptastic photos, but you get the idea.
