Installer

Installer is the large block enemy in Central Computer (Magna Centipede's Stage) in Mega Man X2. If the player crosses in front of a yellow spotlight, several of these enemies will fall from the ceiling and slide around on the floor. These try to crush X (and if they do so, kill instantly). They come in grey and purple shades, the purple one being the only one that can be destroyed. The Silk Shot can easily take out the purple ones in one hit.
