Queen Luna was the grandmother of Luna, the leader of the current Lunataks. She gained magical powers through the Mumm-Rana's Belt. She terrorized Third Earth, enslaving many of citizens and forcing them to work in underground Thundrillium mines. Eventually she was defeated by Mumm-Rana, as she was the only one who's power was greater than Queen Luna's. Afterwards, Mumm-Rana banished her to the Third Moon of Plun-Darr.
