R-1/A Flying Dog is a robot used by G.U.N. to try to stop Rouge from escaping Prison Island after she retrieved three Chaos Emeralds. It trapped her in a locked safe, but was defeated. It appeared in both Sonic Adventure 2 and Sonic X, but their storyline was the same.
According to Sonic X, it is 3.6 meters in both height and width, and weighs 5.4 tons. There is also an unseen two seater version that presumably looks much like the standard version but the technical data is the same.
