Gordo is an indestructible passive enemy in the Kirby series of video games. It's a purple metal ball with spikes on its body/head and two big eyes. It doesn't actively fight, instead if you bump into it, you get damaged. Pictured above is Gordo being thrown by King Dedede in Super Smash Bros. Brawl. Gordo papercraft designed by Charles Bradbury.
