Laser Robots are metallic, gray, robots that make their only appearance in Super Mario Galaxy as enemies who try to defeat Mario by firing lasers at him. The lasers go out from the laser robot in a circular ray like a shock wave and if they hit Mario he will lose one health. Laser Robots constantly fire out circular ray-lasers whether Mario is near or not and the lasers have a limit as to how far they can go before they disappear.
Laser Robots are invincible, they cannot be defeated by anything less than Rainbow Mario himself or maybe invincible to Rainbow Star. Mario can throw Bob-ombs at the robots but they will still not be destroyed and will resume their attack momentarily (citation needed). There is, however, a way to stun the robots, impairing them for several seconds and giving Mario refuge from their barrage of attacks. If Mario jumps on top of the robot at it then the robot will stop laser-ing Mario for a while, but it WILL NOT transform into a trampoline, and it IS NOT Purple, or else it will be a Spring-head Shockwave Generator. Also, firing a star bit to it WILL NOT stun it and it will still generate shockwaves.
Laser Robots first appear in the Battlerock Galaxy and then they appear in Bowser Jr.'s Airship Armada and the Toy Time Galaxy.
