Prism Guardian (プリズムガーディアン Purizumu Gādian) is the mid-boss in Shining Firefly's stage in Mega Man X5. When fighting against it, three block-shaped laser cannons will come down from a rope, two pink and one black. They will shoot strong lasers at X or Zero so you'll want to get on top of one of the blocks or get to an area where one isn't firing. The black one is the only one that can be destroyed. When the black one is destroyed, the other two blocks will go back up the rope and reappear a few seconds later with a new black one. If the black laser head is destroyed enough times, all three will explode. Its weakness is Ground Fire.
