Destructo is an alias that appears in Sonic Underground. It was Dr. Robotnik's alias in "Castle Conquest," a video game that he was a great at, and that Sonic and Manic the Hedgehog often played. He made new software to enhance the game, but in the end he had been leading Sonic and Manic into the game to destroy them once and for all.
