Rhino Spike

The Rhino Spike is a robot deployed by the military organization Guardian Units of Nations in Sonic Adventure 2. It resembles a Rhino Jet with spikes on top. It usually patrols an area, but it revs up and rams toward the player once it spots him/her. It can only be destroyed by a somersault from Sonic and Shadow, but a simple punch or kick will do for Knuckles or Rougerespectively. Upon its destruction, it awards the player 100 points.
