Psycho Goreman

After unearthing a gem that controls an evil monster looking to destroy the Universe, a young girl and her brother use it to make him do their bidding.
Siblings Mimi and Luke unwittingly resurrect an ancient alien overlord. Using a magical amulet, they force the monster to obey their childish whims, and accidentally attract a rogues’ gallery of intergalactic assassins to small-town suburbia.
