Hologran

Holograns (ホログラン) are mostly found in Shadow Man's world, but they also appear in the third section of Dr. Wily's castle. They make the level difficult by causing the whole screen to go black (like in Dr. Wily's final form in Mega Man 2). This is especially dangerous when you go back to Shadow Man's lair in search of the first Doc Robot, as it can also prevent you from seeing pits. the Magnet Missile is the best weapon to use on it as in can hit it no matter what and turn the lights back on.
