Mego Micronauts. I used to have most of these figures when I was a kid. I had the solid-colored time travelers too. If I had the money, I would set up a business selling these. They are very cool, and there are people that are willing to pay big bucks for these toys.
SHOGUN WARRIORS - Before Transformers there were Shogun Warriors! In the early 80's my Japanese friends in Australia introduced me to these and I was obsessed! All I wanted was a Shogun Warrior for Xmas. Alas I never got one. It was substituted for a .22 Rifle for use at the gun club and our farm. Not a bad substitute in hindsight!
