In my joe verse, Cobra is an evil army similar to the Nazis from WW2. Advanced weaponry and deep into the occult. So here's night creeper with the two headed wolf from Chap Mei. The creature was summoned from hell.
There are more to come of how I made use of toys from other lines.
Please share some pictures here for more ideas. It could be some 1:18 scale bikes for the dreadnoks, those awesome Chap Mei military vehicles, star wars, indiana jones etc.
