The Mega Hyper Heroes are the babies' favorite superheroes. They protect the Universe from evil and save the environment. They transform via magic rings that they all wear. All four of them need to be together in order for the rings to work. There are many Captain Planet type elements in the show such as protecting the rainforests and using magic rings however their powers are based on the powers of the Fantastic Four and Teen Titans. They are drawn in 80s superhero style as opposed to rugrats animation.
