Bodies: Marvel Universe Puck
Head: ??

In 1976, at the tail-end of GI Joe's original run, the Adventure Team had grown to include characters such as Major Mike Powers and Bullet Man. That year, in an effort to increase Joe sales, Hasbro created a new enemy for Joe to fight: The Intruders. These super-smart aliens resembled cavemen and had a ''bear hug'' feature that allowed them to trap Joe in their powerful arms.

For the Intruders, I decided to have a little fun. I used Marvel's Puck figure as a base and swap the head with something I had in my fodder. It's not 100% accurate in that the Intruders should be a bit taller and have some armor. Maybe these are baby Intruders?
