Aero-Cannon

The Aero-Cannon is an unusual floating robot found during the day stages of Sonic Unleashed. With the appearance of a mis-shapen blue Egg Pawn with a blue cannon in its chest, it floats in mid-air like a Spinner and tries to shoot down Sonic like an Egg Launcher. There is also a gold variation. The Aero-Cannon will return in Sonic Generations along with Rooftop Run, as seen in a Modern Era Trailer
