The Overmaster is a supervillain from DC comics.

The Overmaster is galactic wanderer who destroys civilizations if he deems that they are not worthy to continue existing. It is not known how long he has wandered the cosmos but along the way he has accumulated alien oddities, including those that are the last of their race. He has fought several incarnations of the Justice League and utilises Heralds in a similiar fashion to Marvel's world-devourer Galactus.
