Ray Trap

Ray Trap (レイトラップ) is a device from the Mega Man X series that is used to stop intruders. Ray Traps appear in Boomer Kuwanger's stage and two of the final stages in Mega Man X, and the first Laguz Research Laboratory stage in Mega Man Xtreme 2.

They are connected to motion detectors that flicker on and off. If X is standing in the sensors when they are on, all Ray Traps in the area will shoot lasers in his general direction.

Other media
In the Rockman X manga, X accidentally activated a Ray Trap while infiltrating Boomer Kuwanger's tower, revealing his position to the Mavericks.
