I remember that the Legions of Power figures were some of my favorite toys of the 80s. I still have two of them but no parts from the vehicles anymore.
The figures had hard plastic bodies with rubbery limbs and were only about a centimetre high. The good guys and bad guys were colour coded and all wore the same style of armour; with the exception of the two leaders.
Released in 1986 by Tonka the motorised machines all came as separate parts so you had to build them together. There were instructions showing you how to build the different Legions of Power vehicles or alternatively, you could just build "off the cuff". Every set included figures who were generally known as Lieutenants.
Here's the story behind Legions of Power:
"An earth space probe enters a distant solar system and explodes! Like meteors, mysterious high-tech components rain down on two warring planets.
Discovering vast power in these components, Wartech, the evil leader of Planet Konn, plans to take his Tech Dynasty and invase the nearby planey of Prolon
Jeffroon, leader of the good Star Legions, must use his newly developed Computer Power Units to build defense vehicles that will protect Prolon.
It's a war between armies of powerful new machines...Legions of Power!"
