Decoe is a golden tall and lanky humanoid robot who personally assists Dr. Eggman in his conquest for world domination. He works in tandem with Bocoe in the doctor's various plots to defeat Sonic The Hedgehog, though they hold no ill-will towards the hedgehog, nor his friends. While originally very clumsy, absent-minded and stupid due to his old ridged programming, Dr. Eggman has since then upgraded Decoe, giving him better combat performance with close-quarter weaponry, and a higher sense of intelligence, snark and attitude (though is still prone to screwing up).
