Gorea is much more complex than fans may realize. In Alimbic Lore, it is said that Gorea copied the cell structures of the Alimbic. Gorea then gains their great minds, telepathy and intellect, and exoskeleton properties allowing the creature to survive on their harsh homeworlds. Now time to look at the cutscene where we see Gorea phase 1's interaction with the other hunters. Many fans just think Gorea absorbed the 6 hunters' respective weapons, but Gorea did much more than that. The being also copied each hunter's cell structure into memory due to the creature's color-changing features. If not, Gorea would be using the same functions for each hunter like Samus's subweapons do; however, Gorea uses the affinity versions of each hunter's respective subweapon. The hunters are the only beings with the that ability respectively. Keep in mind the abilities of each hunter goes deeper than their affinities.
Gorea enhances the weapons it gains from replicating the cell structures of these hunters. Yes, Samus will burn from getting hit by the Magmaul just as she would if hit by Spire; however, look at the Gorea's Magmaul impacts against the arena wall. You'll see smaller Magmaul bullets flying out from the fiery impact. Also Gorea can charge up the BattleHammer to produce an assualt of rapidly released explosives. The Shock Coil's reach goes out farther than with Sylux. The Volt Driver's charge rate has increased from Kanden's. The regular Judicator shoots in bursts of 3 when used by the menace where as with Noxus, it is only one bullet uncharged. With the Imperialist, the ability is harder to see besides the fact that Gorea's form of the weapon has a charge feature.
The thing that remains a constant though, is that Gorea's Armor color represents the weakness it currently has. Like how the weakness is the Shock Coil when the creature has blue armor using the Imperialist, then when it has red armor with the weakness as the Imperialist the being uses the Shock Coil. My point is there is an interaction between weakness and armor also weapon and armor. With that being said, when Gorea's armor is gray its weakness is the Omega Cannon...So what? The thing is that Gorea also has a armor relation here. At the beginning of the Gorea battles, Gorea's armor was black. This would mean that with that armor cell type active, Gorea would be using the Omega Cannon against Samus Aran. Where as with the gray armor, Gorea would be using the weaponry that would be the weakness to its black armor. The thing is, Gorea releases this armor cell make-up into the air as a black vapor before the showdown begins with the legendary Samus Aran. It's clear to me that Gorea's weapon is the Omega Cannon, and used it against the Alimbics during the Alimbic War (thus the view of abomination is set upon the weapon). Also, Gorea is the 7th new hunter featured in Metroid Prime Hunters...
Hunters of Hunters
- Samus Aran--Missile Launcher
- Kanden--Volt Driver
- Spire--Magmaul
- Weavel--BattleHammer
- Noxus--Judicator
- Trace--Imperialist
- Sylux--Shock Coil
- Gorea--Omega Cannon
One more thing, the weapons that Gorea copies can't kill it. With that being said no weapon in the Alimbic Cluster can "kill" Gorea. In fact, Gorea doesn't even register as a "kill" within the enemy kill record, where as every other enemy does and doesn't count as a defeat like with the hunters. Also, in the final ending we see a gray object fly out from the Oubliette. This has to be a peice of Gorea phase 2, as no part of the Oubliette is gray at all. Don't forget, Gorea retains the cell make-up of each hunter besides Samus Aran herself.
BlastCap
"A large mushroom that explodes on contact, emitting noxious gas. Originating on Tallon IV, its spores can survive without atmosphere and have propagated throughout the galaxy on solar winds."propagatedWith that definition taking into account, and with the abilities of the Shock Coil. Gorea can absorb the life energy of the spores found throughout the Tetra Galaxy to replenish its own. Then, having the mental intellect of an Alimbic, it could possibly copy the cell structure of the BlastCap spores. Thus it could then reproduce itself in said form using the spore's ability to propagate, to restore itself to its former physical size in the beginning of the showdown with Samus Aran.
Now what about that black vapor that had the armor type that would use the Omega Cannon? That is the Omega Cannon and here's why. At the beginning of the phase 1 battle, Gorea releases the black vapor and it flows upward. How does Gorea get to the Oubliette room containing that weapon? By flying upward. Both the vapor and physical Gorea could gain access to the chamber, and there's a time difference in between arrivals. Plus, Alimbics know of extradimensional exploration (History 10). With that, the black vapor wouldn't have a problem accessing the chamber without the help of the 6 beam cannons stationed in the Phase 1 chamber. Being that the Black Armor would use a weapon that is the weakness of the Gray, the Omega Cannon would be able to damage the Phase 2 form of Gorea.
The Omega Cannon being the black vapor Gorea releases at the beginning is supported by this as well. Throughout the whole game, Samus Aran gets telepathic messages from the Alimbic Elders after collecting Octoliths in the form of text. Before the Gorea 2 battle, it says all Alimbic essence has left the Seal Sphere; however, it never said anything about the elders leaving the Octoliths. This Alimbic essence is that of regular Alimbic citizens under the elders. Making them weaker in the areas known for by the Alimbic people. Now with that being said, the telepathic message she is sent at the end is sent by 3 regular Alimbics. My point is that if an elder can't produce a vision to Samus Aran at close range with the Octolith, how can 3 regular Alimbics have such ability? Samus now has the Omega Cannon, that's why. Gorea's telepathic abilities within the cannon (being a form of that black vapor) strengthened Samus's telepathy allowing her to see a vision of thanks thinking Gorea was gone......
