Necrosaur is the boss of the Acid Creatures area in R-Type III: The Third Lightning. It's a Bydo defense organism built into the cellular wall. The only vulnerable point is the large eyeball that moves vertically within the wall. There are several orifices within the wall that launch sperm-like projectiles (these were changed to eyeballs in the US version) in various formations. While this happens, the eye can constantly shift is position, sometimes closing to avoid attacks, and even shooting slow-moving projectiles at the player. Pilots must navigate this onslaught of bio-matter while firing Wave Cannon shots at the eye; due to the eye's mobility and protection, the Mega Wave Cannon performs better than the Hyper Wave Cannon. The Cyclone Force's red laser attack is also capable of damaging the eye. Necrosaur's projectiles are solid enough to block most attacks, rendering Missiles useless. As the Necrosaur takes damage, its eye becomes increasingly bloodshot, and it fires projectiles at a faster rate.
