Captain Action (Ideal Toy Company, 1966)
Captain Action was the rival to Hasbro’s G.I. Joe — even though both were created by toy developer Stan Weston. Captain Action was equipped with a wardrobe that allowed him to become Superman, Batman, Spiderman, Captain America, Aquaman, the Lone Ranger, the Phantom, Flash Gordon, Buck Rogers, Sgt. Fury, Steve Canyon or the Green Hornet.
In 1967, a sidekick, Action Boy and an enemy, Dr. Evil were added. Then a line of female figures were added. The ladies were individually designed and were singular heroines (unlike Captain Action that you could to make whomever you wanted). The females introduced were Batgirl, Supergirl, Mera and Wonder Woman.
In 1968, Captain Action was discontinued. Any character or even just an outfit can fetch you a pretty penny with collectors.
