Exxor (also spelled Exor) is the home planet of the Wonder Twins, Zan and Jayna and their space monkey, Gleek. Many years ago, a conquering alien species invaded Exxor forcing a large portion of its civilian populace to flee. The Wonder Twins exiled themselves, and eventually came to Earth, where they became honorary members of the Super Friends.
- The planet Exxor was originally exclusive to the continuity of the Super Friends animated series and the Super Friends comic book adaptation. It is also the birthplace of the manistream Wonder Twins in modern continuity.
