Ring Beamers are spiked yellow mechanical enemies that appear in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. When Mario approaches, they attack by emitting a circular shockwave that damages him if he touches it.
Super Mario Galaxy
Ring Beamers first appear in Super Mario Galaxy, featuring in the Toy Time Galaxy and the Dreadnought Galaxy. They are stationary enemies that fire lasers in a circular shockwave formation, which will damage Mario if he makes contact with them. They cannot be destroyed or stunned by any means.
Super Mario Galaxy 2
Ring Beamers reappear in Super Mario Galaxy 2, behaving identically to their first appearance, appearing in the Shiverburn Galaxy and the Grandmaster Galaxy. They can be immobilized by the Co-Star Luma.
