Emperor Ing

The Emperor Ing was the main antagonist and penultimate boss in Metroid Prime 2: Echoes. The eldest and strongest of the Ing, as well as leader of the Ing Horde military government, it resided in its personal Sanctum within the depths of the Sky Temple, from where it presumably gave orders to its troops. The Emperor was the very first Ing born after Dark Aether's creation, but was since mutated and strengthened by Phazon energy; it later empowered itself further with the stolen Light of Aether during its battle against Samus.
The Emperor was capable of manipulating both dark and light energies to create devastating attacks.
==Phases of battle==
===First phase===
In its first form, the gigantic Emperor Ing consists of a large, spherical head atop a stalk-like, stationary body. Samus can scan the Emperor's Body, Head, and Eye separately. To defeat the Emperor's first form, Samus must find a way to expose the creature's single eye, which is its only vulnerable weak point. In order to bring down the Emperor's defenses, Samus must first deal with its tentacles, which it uses to attack Samus in various ways. The Emperor will try to whip Samus into the Phazon that lines the arena where it is fought by swinging its tentacles around. The Emperor can use its tentacles to charge up and launch powerful dark energy spheres at Samus. It can also create miniature portals, through which it jabs its tentacles in an attempt to impale her. However, destroying a tentacle often leaves behind pickups.
After Samus causes the Emperor to retract all of its tentacles, the creature's eye, which can be scanned separately from the rest of its body, will be temporarily exposed. The eye has two protective hemispheres rotating around it, and Samus must fire through the narrow break between them. Samus must lock onto and maneuver around the eye, as the protective hemispheres rotate around it constantly, alternating their direction erratically.
While its eye is exposed, the Emperor can fire a powerful laser from it, which can stun Samus and prevent her from shooting. This particular part of the battle is reminiscent of Spore Spawn from Super Metroid, where the boss's weak point is exposed for only a brief period of time. Eventually, the Emperor Ing will regenerate a protective covering for the eye, and sprout new tentacles. Throughout the battle, the Emperor Ing regrows its tentacles in varying numbers, until Samus finally deals enough damage to the Emperor's exposed eye. Any weapon can damage the eye, though the Sonic Boom seems to deal the most damage.
===Second phase===
In its second phase, the Emperor encases itself in an impermeable, magnetically-charged shell reminiscent of a Luminoth Energy Controller or an Ingclaw. This cocoon-like incarnation of the Emperor is covered in circular vents that immediately begin to expel a poison gas at the start of the battle, forcing Samus to scale the cocoon with the Spider Ball in order to avoid the purple fog covering the floor. In this stage, the Emperor is undergoing metamorphosis, and Samus, unable to cause any real damage to the pupating Emperor inside, must destroy the 11 vents on the cocoon. This can only be done by damaging the tentacles that emerge from within the vents as Samus draws near them, a difficult task to accomplish, as the tentacles whip around viciously and can actually dislodge her grip on the cocoon's surface. To make matters worse, Inglets in their liquid forms also emerge from the chrysalis and follow Samus around, often ganging up on her in groups. Samus must employ her Bombs to destroy the tentacles that emerge and fight off the Inglets that relentlessly attack.
The Inglets and tentacles are a blessing in disguise, as destroying these yields bountiful health and ammunition. Samus can use this time to fill up on much-needed health using Power Bombs to destroy multiple nuisances at once. It is possible to delay or speed up the Emperor's pupating process by strategically choosing when to bomb the vents from where tentacles emerge. As Samus destroys more tentacles, the vents begin to release more gas into the room, causing the height of the toxic, purple cloud to fluctuate and making anything beneath it extremely hard to see. At points, the gas rises to such a high level that only the small area near the cocoon's top is left uncovered. If Samus waits here for the miasma to recede, she will be safe from its damage, but will become easy prey for swarms of Inglets, which are also hard to see through the fog.
There is a hidden time limit to this phase: The poison gas will eventually rise above the cocoon and stay that high, making its constant damage unavoidable. Those intending to prepare for the final phase by collecting as much health and ammunition as possible should remember which vents have not been destroyed yet so they can do so as soon as they're ready if this time limit expires.
Once all 11 tentacles have been destroyed, the shell of the chrysalis breaks open, and the Emperor emerges in a mutated form.
===Final phase===
In the Emperor Ing's final form, its orange glowing heart has become unstable due to increased exposure to Phazon and the Light of Aether, exposing it in the open. However, the extreme physical mutations have given the Emperor far more mobility than its previous forms; in this form, it is more arachnid-like in appearance and bears a resemblance to a giant Warrior Ing with three large horns resembling a crown. With a new health bar, the Emperor Ing's only weak spot is its very large heart, located inside a mouth-like opening barely covered with strands of black flesh which it can open and close at will.
The Emperor Ing can use a large variety of attacks and abilities, though a few select ones are only available when the Emperor's heart is in specific polarities. While its heart is purple, it can create a powerful beam of dark energy from the tip of its crown that freezes on contact, as well as creating dark puddles on the floor with its foremost leg that spawns Nightbarbs. When its heart is white, its crown can project a large beam of light energy that ignites Samus on fire, and the Emperor can also spawn LightSwarms from its mouth-like orifice in a "spitting" motion. Both Nightbarbs and LightSwarms provide protection by flying around the Emperor's main body, making it difficult for several of Samus's attacks to breach through their large numbers; some of the creatures are consumed by the Emperor to recover health. Like the Inglets from the previous phase of the battle, the spawned enemies can be destroyed for plenty of pickups, preferably with attacks containing a large blast-radius, such as the Sonic Boom.
All other attacks the Emperor Ing possesses can be used regardless of its heart's color. When its entire body crouches and shakes, it is either preparing to employ a shockwave-inducing jump similar to the Jump Guardian, or create numerous rifts nearby that will each simultaneously shoot out a light energy beam reminiscent of the Warrior Ing's transdimensional energy. It will also try to skewer Samus with its three front legs covered in dark energy if she is close. Each time the Emperor Ing's health is lowered by approximately 1/3, it will close its mouth and shake from side to side as its emits a humming noise that increases in volume; this event lasts for a short moment, but it signals the addition of a new attack it will be using throughout the battle. The first one involves the Emperor rushing towards Samus while it tramples the floor violently, forewarned only by a long roar as it slowly stretches its mouth open. The second one involves the boss quickly sliding across the entire room with its legs; this is foreshadowed by the creature stomping the ground twice in a row in large motions, and it occurs only after the trampling attack. The slide attack is extremely fast and hard to avoid, but if Samus manages to dodge it, the Emperor will run into a wall where it will stand still for a moment, revealing a small hole on its back that can be targeted since it leads to its heart. The hole is most accessible when the Emperor Ing raises its foremost leg to the level of its maw.
When the Emperor Ing's heart is orange, its health bar cannot be reduced, serving as a sort of barrier. Thus, Samus must force the Emperor to change its heart's polarity in order to damage the boss. To do this, she needs to bring down the orange barrier by hitting its glowing organ with any combination of weapons, though Super Missiles are the best option since they do not consume ammunition from beams capable of harming the boss. Once its heart changes, it becomes vulnerable to a beam of the opposite polarity: when the heart is white, it is vulnerable to the Dark Beam, and when it is purple, it is vulnerable to the Light Beam. If Samus has collected enough Beam Ammo Expansions, the Annihilator Beam is her best choice, as it can hurt the Emperor in both polarities. After a while, the Emperor will bring the barrier back, reverting its heart to orange and repeating the process. As the battle progresses, the boss will start to rapidly switch between light and dark polarities whenever the barrier is down in an attempt to make Samus's beams hit the same polarity, causing no damage. When the fight nears its end, the heart will glow increasingly brighter, making intense rays shine through the thin dark strands that connect the top and lower portions of its maw.
When the Emperor Ing's health bar is entirely depleted, it dies, exploding into purple particles and smoke. The creature yields the last Light of Aether for the Main Energy Controller. When Samus absorbs it, Dark Aether loses its stability and begins to collapse, giving her a few minutes to escape before the planet is eradicated.
==Logbook entries==
==Unused Data==
In the Metroid Prime 2: Echoes Bonus Disc, the Logbook Data for Emperor Ing highlights an almost completely different battle. The Data Network simply lists the separate Emperor Ing scans by number, totaling four different phases for the entire battle. Some of the text for these multiple scans are slightly different than what is seen in the final, suggesting the possibility the entire fight was cut down due to length. Notable differences are as followed:
*Emperor Ing 1 has no mention of the final Energy Controller, but does mention mass amounts of Phazon, which match with the room seen in the final. This battle seems to involve targeting Phazon clusters on the target's body. This may have been slightly similar to how the Omega Pirate was fought, though the exact nature of this scrapped battle is unclear.
*The battle with Emperor Ing 2 would involve using the Echo Visor during combat. The scan states the creature also would have summoned lesser enemies to battle Samus. Both a targetable heart and lesser (non-aggressive) enemies appear in the Mutated Emperor Ing battle in the final game. 
*Emperor Ing 3 appears to be the Chrysalis form and lists has 8 vulnerable spots on its shell. Flavor text was also added to the final Logbook entry, stating the shell is magnetic.
*Besides a one word change, Emperor Ing 4's scan is virtually identical to the Mutated form's final scan in the Gamecube version. This is because the scan references a scrapped version of the fight and developers likely forgot to remove and update the Logbook entry (see trivia). A revised Logbook entry was included in Trilogy.
==Trivia==
*The Emperor Ing is the only boss in Metroid Prime 2: Echoes guarding a portion of the Light of Aether that does not reward Samus with a power-up after its defeat.
*It is possible the Emperor was the guardian of Aether's Leviathan, which is believed among fans to be the Sky Temple itself.
*If Samus deals the final blow while the heart is purple, the resulting cutscene will show the Emperor dying with a white heart. This is likely because in an optimal battle, when Samus can deal maximum damage every time its hearts shifts, the final blow would be to a white-hearted Emperor Ing.
*The Mutated Emperor Ing shares many similarities with Metroid Prime's Exo form from the previous installment. Both large creatures possess a similar black colored multi-legged body structure with all but their center core being impenetrable (the face for Prime and the heart for Emperor Ing). Both can also summon unscannable creatures that drop power-ups and both can fire a large beam capable of either inflicting heavy burn damage or can freeze Samus. Both are also the penultimate boss in the respective titles they appeared in and are housed within a final new area explored. Coincidentally, both Metroid Prime (as Dark Samus) and Emperor Ing are fought as the Penultimate Boss within a room called the Sanctum.
*The first scan that indicates the Emperor is the Ing's alpha and omega, and due to these being the first and last letters of the Greek alphabet, can be taken literally as the Emperor being the beginning and the end of the Ing. This is very fitting, considering it was the first of the Ing to exist and its defeat at the hands of Samus causes the destruction of its world and the entire race.
*The fight with the Emperor Ing's first form is very similar to the fight vs. the Old God C'thun in World Of Warcraft. The boss fight against C'thun also involves a separate body and eye, tentacles the player has to kill and an eye that shoots lasers.
*If Samus shoots at the liquid form of the Emperor Ing in the Sanctum before dropping down into the chamber, it will disappear until the cutscene. No damage is dealt to the Emperor by doing this.
*It is possible to inflict severe damage to the Emperor Ing's final form by colliding into a certain location on the underside of its body when using the Screw Attack. This is best done when Emperor Ing jumps up, in which case Samus can Screw Attack under it if near enough to it.
*Unused collision data for the Mutated Emperor Ing suggest the fight was originally much more complex, and is possibly related to the previous trivia. Leftover scan data reveals the Emperor Ing would have been able to summon a shield of either light or dark energy, which Samus would need to destroy using the opposite beam: These weak spots are still partially present on the Emperor Ing's "knees". Concept art shows glowing red orbs matching the color of the Emperor's heart in each "knee joint". It would have shared this weakness with Quadraxis.
**Curiously when it is defeated, it stumbles and falls flat on its body, with its explosion occurring moments after. This scene may have been based off of early scan text stating that Samus "immobilized" the creature.
*The Mutated Emperor Ing glows yellow when its core is hit with the Death Ball (via hacking). No damage is inflicted to it however.
