I was not a huge fan of IDW's GI Joe re-launch, though there were some good ideas here and there, and I liked some of the new characters introduced. Sixgun is one of those characters.
Sixgun is based on the short lived IDW character of the same name. I saw some good potential in many of those "made to die characters", and wanted to integrate them into my Joeverse.

Sixgun is a part of the team's infantry, and often rides into battle on the RAM. He is often tasked with quick recon missions and providing infantry support for the mechanized division.
