This Mr. Mxytplik action figure is part of the first series in the "World's Greatest Heroes" line and is an exact replica of its original 1970's counterpart released by Mego.
Super Friends team up to fight the ranks of the Legion of Doom. But that's not all they face. Picture if you will, Batman vs. Bigfoot, Superman vs. a Star Creature, Wonder Woman vs. Washington, Aquaman vs. Atlantis and more.
The most powerful heroes ever--Superman, Wonderwoman, Aquaman, Batman and Robin--join forces with teenagers Wendy and Marvin and their dog, Marvel the Wonderdog, to defend justice and guard the innocent.
