Remco created the Crystar action figures before sending them to stores in 1982. These characters also appeared on the pages of Marvel Comics starting in the spring of 1983. Remco made these action figures translucent to appear to be made of crystal. Contrasting this, Moltar and the other members of the Chaos team were designed to appear to be made of lava. This series consisted of seven figures, plus nine beasts, machines, and playsets.
