DoroDoron

ドロドロン,

DoroDoron is the third Dark Fall to assault Earth following Moerumba's failure. He is an arachnid-like creature that moves underground rather than through the air. DoroDoron transforms earth-related objects, such as rocks and cobblestones, into Uzainaa monsters. He also occasionally takes commands from two suspicious girls (Kaoru Kiryuu and Michiru Kiryuu) who are in the same class as Mai and Saki. His name derives from the word "doro," which means "mud" in Japanese.
