This fight is extremely difficult and requires a lot of energy and ammunition. Before entering this battle, make sure you have full health and ammunition. This fight is very long and there are only a few opportunities to gain power-ups. The first part of the fight begins with the Emperor Ing head and body. Do not forget to scan these, especially if you are trying to fill your log book. The head has some tentacles that perform a variety of nasty attacks. You must kill the tentacles to make the head expose the energy core. The easiest way to kill the tentacles is to use the Seeker Missiles to get rid of them all at once. Note: Although the Annihilator Beam homes in on the tentacles, you will need the ammunition for later in the fight. After the defeat of tentacles, they will occasionally drop ammunition or energy. Once the tentacles are defeated, the head will diminish, exposing the energy core. Do not forget to scan it. You must find the opening and shoot it with a charged shot from the Power Beam or the Annihilator Beam. For ammunition conservation, the Power Beam is recommended. This may take longer, but it will pay in the end. While the Emperor Ing is in this state, it will shoot a beam of energy at you that does a hefty amount of damage and cause you to lower your weapon. Side-dashing is the easiest way to dodge this beam. As the Emperor Ing's energy diminishes, the attacks brought by the tentacles become more intense. Once the energy core is defeated, the head will cover the body and form a sphere. This begins part two of the battle. You must immediately scan this and turn into the Morph Ball. Use the Spiderball to attach yourself to it. There are numerous amounts of bright spots on the sphere. In order to damage the spots, hover over it until you see black bubble forming over it. Then, immediately drop some bombs and get away from it as fast as possible. A tentacle will appear and start flailing. If you kill it, there should be a hole left behind with purple smoth spewing out. You must do this on all of the holes. Note: Getting hit by a tentacle will knock you in a random direction and cause damage. There are also puddles of Dark Matter moving around the sphere. If you are hit by one of these, you will be knocked off the sphere onto the ground, causing you to take damage from the poisonous fog. To defeat the puddles, wait until it follows you, then lay a bomb and it should move over it when it explodes. These puddles are one of your few opportunities to gain ammunition and energy. They usually drop Blue Energy and Missile Ammunition, but will also drop other things such as Light and Dark ammunition, and Red (and rarely) Yellow Energies. If you are low on energy, take the time to kill a few of these dark puddles to gain back as much as you can. After destroying all the holes of the sphere, part three of the battle begins. Again, do not forget to scan this new form of the Emperor Ing. In order to damage this form, you must shoot its heart, which is located in its mouth. Use the Annihilator Beam to shoot the heart. However, be wary of how it opens and closes its mouth because ammunition is extremely limited. After a few shots, its heart will either turn white or dark purple. If it turns white, it must be shot with the Dark Beam. If it turns purple, it must be shot with the Light Beam. Your best bet is to keep using the Annihilator Beam because it damages the heart no matter what color it is, but watch your ammunition. Do not charge the Annihilator Beam because the chances of it missing are high since Emperor Ing's large legs get in the way - this would be a waste of five Light and Dark ammunition. After defeating The Emperor Ing, Samus will have to get out of Dark Aether within seven minutes.
