Chaos Emeralds

In the past, Maugus bore the Chaos Emeralds but parted with the artifact when he left aboard the Proudstar. When Sonic The Hedgehog explored the scuttled Proudstar millions of years later, the Chaos reacted to a dark presence in the ship, shutting down for a second. As the Sonicbots ventured deeper into the ship, Teletraan Alpha used the Chaos to see their future. As the Sonicbots neared the ship's core and discovered the same dark presence, the Chaos allowed Sonic to learn that the entity responsible for corrupting Maugus was searching and destroying its way to Skylands.
