WENDY, MARVIN, & WONDER DOG!
In the first two seasons of the SUPER FRIENDS, Wendy and Marvin, and their pet canine Wonder
Dog, helped Superman, Batman, Wonder Woman, and Aquaman battle all sorts of enemies of the Environment! Although
they had no real super powers, Wendy and Marvin and Wonder Dog were unnaturally clever in the tradition of Velma and Shaggy
and Scooby Doo.
