Rhino Metal, リノメタル, is a GUN robot that appears in some of the stages of Sonic Adventure 2 and is part of the Rhino series. It's a Rhino Jet with thick armour. It usually patrols an area, but it will rev up and ram once it spots a character, and it delivers powerful attacks, to the point of throwing a character off the stage, though it's very easy to trick them to fall off instead. They are very difficult to destroy and it awards 100 points when destroyed.
