Marshageddon

Marshageddon was Marshmallow's evil cousin and the main antagonist of the Annoying Orange episode Sour Rangers. He entered the kitchen and began destroying various puppies with his raygun, including a poodle and a pitbull. This prompted Pink Pumpkin, Yellow Squash, Green Courgette, and Red Zucchini to rescue the kitchen from his wrath. However, Marshageddon jumped into his magic microwave, resulting in him growing to a massive size. When he asked The Sour Rangers if they had any last words, Oron states that he has only one, Which is "KNIFE!". The Sour Rangers then formed Megagourd, which slashed Marshageddon with the Power Knife, causing him to explode.
