Mothraya (モスラーヤ Mosurāya) is a giant robotic moth, and is the boss of Cossack Stage 1 in Mega Man 4. The red flashing light is its weak point, and Ring Boomerang is the best weapon to use (though Drill Bomb, Pharaoh Shot, and Dust Crusher are also good options). It can thrust its spike-tipped "proboscis" into the floor, causing a part of the floor to be destroyed. The Pharaoh Shot, while it deals normal damage, can be used to deal additional damage if the player is willing to risk moving along the floor with the boss.
