Bowser is the worst of the worst when it comes to the Mario series, and he is persistently terrorizing the citizens of the Mushroom Kingdom. He hates Mario and Green Mario to no end, and sees them as a threat to his rule over the land. He is also classified as the heaviest option in any Mario sporting game, where even Wario and Donkey Kong are feeble in comparison. Print out this big brute and paint him however you like!
