Emperor Metallix

Metallix the Metal Sonic is a major character in Freedom Fighters NEO, being the anti-heroic deuteragonist for the most part and the main antagonist of the Mecha Sonic Saga.

Appearance
Metallix was created in the image of Sonic the Hedgehog and is thus mostly built of blue metal. His muzzle, chest and arms, however, are peach colored, mostly to match Sonic's. His head has metal fins resembling Sonic's quills and a pair of triangular "ears." His hands are made of silvery metal, and he has red feet with white stripes designed to resemble Sonic's shoes. He has optic sensors with black sclera and red irises.

After gaining 7 Chaos Emeralds, though, his appearance changed. Metallix now resembles one of his "Sonic the Comic" counterparts, who resembles Mecha Sonic from "Sonic 3 and Knuckles", having body armor with a Chaos Emerald seen embedded into it, blue shoulder plates, larger gauntlets and leg armor, a plate covering his pelvis and elf-like shoes.

In his final base form, Final Metallix, his design resembles his game counterpart's NEO form. His head has five long quills as opposed to his regular three, with white stripes and markings around his eyes, similar to that of Shadow's. The yellow color in his ears has been replaced with red and his nose is now black. His shoulder plates became black and curved, his gauntlets became more sleeve-like, and his leg armor now has white outlines. He also sports a spiky belt with a black cape that protrudes out of the back of his waist. This body was built by the Brotherhood of Metallix to show Metallix' status as their emperor.

One would say that Dr. Koopa's design is a fusion between Sonic 3 and Knuckles' Mecha Sonic and Megaman X. True to that, he can transform his arms into a weapon similar to X's X-Buster, called the Spin Dasher. Also, like many Reploids, he has a weakness, namely Zero's Z-Saber and, for a short time, M'egga Man's Egg Laser. Ironically enough, the Spin Dasher is M'egga Man's weakness, as well as Rock's and Quint's.

Old origins
Metallix was built by Bowser Jr. for the sole purpose of assisting the Freedom Fighters. He was unleashed, apparently prematurely, to save Sally from being roboticized after she was fooled by Eggman. He was, however, given a free will, as well as the ability to copy any kind of data. Bowser Jr. told Metallix that Sonic and Sally have something called "soul", giving Metallix the desire of having a soul of his own. He also told Metallix about the Genesis Waves.

New origins
Metallix is actually Sonic Man, an alternate future version of Sonic which was defeated and roboticized by Dr. Robotnik. Sonic Man was sent to past to prevent Sonic from ever becoming a Freedom Fighter. The plan failed, as Sonic Man was sent too far in the past, causing him to go on a rampage that killed many scientists and robots, until Dr. Albert W. Wily unleashed Zero on him. Zero manages to stop Sonic Man, but Dr. Light, Blues and Roll were already dead, which caused Quint to commit suicide. 12'000 years later, Dr. Koopa found Sonic Man and salvaged him for parts which could be used for MeteorTech. When Project:Metallix started, Bowser Jr. built a robot, who he dubbed "Metal Sonic", out of Sonic Man's parts. Metal Sonic was activated on the day Tails was born, the same day Robotnik took over Mobotropolis. On that day, however, Metal Sonic vowed he will be the one in control of his life.

Dr. Eggman Saga
A notable event was Metal Sonic's battle with Universalamander, which reveals some lore to Metal Sonic. It is revealed that Metal Sonic was originally made to destroy Mario, along another robot, which was resembling Sally, and that Dr. Koopa was researching on Sonic and Sally ever since he befriended them, which, according to Metal Sonic, was shortly after they were born. At the beginning of the Eggman War, Metal Sonic was repurposed, and the Sally-resembling robot was abandoned.

For that battle, Metal Sonic incorporated in his body 7 Chaos Emeralds, achieving the goal Dr. Koopa originally wanted Metal Sonic to achieve: becoming the ultimate robot, so he would be able to kill Mario. Right afterwards, he changed his name to Metallix and used his newly-found power to destroy Universalamander.

Metallix then had several adventures, which included meeting the Omni-Viewer, Larry Lynx, Knuckles the Echidna, Nicole, Shorty the Squirrel and Tekno the Canary. During these adventures, he figured out that Dr. Koopa didn't built him alone, but rather, that he was part of a project called "Project:Metallix" led by MeteorTech, the company run by Dr. Ovi Kintobor, but Metallix was still Dr. Koopa's design.

Learning that Robotnik was planning to take over Miracle Planet, Metallix goes to stop Robotnik's chief scientist, Grimer Wormtongue. There, he realizes Grimer made his own Metal Sonic. Metallix manipulates Grimer's Metal Sonic into believing they were two members of an "elite brotherhood of robots", which was brainwashed by Robotnik save for Metallix himself. He manages to turn Metal Sonic for the good side, renaming Metal Sonic "Shard". Metallix and Shard then change the machines built to convert the planet in Robotnik's headquarters in such a way that, when Sonic came two months later, Miracle Planet became a resort fitted for the luxury and enjoyment for "anyone who wasn't supporting Robotnik", and Tekno and Shorty were the first two clients, arriving one month before Sonic. When Sonic arrived, Metallix told Shard to kidnap Sally while he kidnapped Amy. Afterwards, Metallix put Sonic's loyalties to the test: Sonic can only save either Sally or Amy and can't ask for help, but at the fork when he reveals his plan, he doesn't explain who on which path is. Luckily, Sonic's heart manages to lead him on the righteous path, saving Sally. Metallix lets go of Amy, as he got what he wanted. Sadly, Shard sacrificed himself to stop Robotnik's failsafe that was meant to destroy Miracle Planet.

Personality
Metallix has a personality similar to Sonic, albeit darker due to his dark past. In battle, he often takes more extreme measures to defeat his enemies, even going as far as to tell the likes of Mario and Robotnik that the other Freedom Fighters are far too merciful to them. He even states that, if he didn't need Robotnik to break the Fazbear Curse, Robotnik would be dead where he standed.

Powers and abilities
Modeled with extreme accuracy after Sonic the Hedgehog, Metallix was made to copy Sonic's every ability, including his speed and power.

Metallix shares Sonic's super speed, which he can achieve using a powerful jet engine-based propulsion system. With this system, Metallix is able to beat Sonic's acceleration, who can instantly accelerate to the speed of sound, and equal Sonic's speed; he is even able to surpass the speed of Sonic, whose highest known top speed is Mach 5. Even then, Metallix can take his speed even further. By overloading his circuits, Metallix is able to quadruple his speed for a limited time. Using certain techniques, he can even achieve light-speed momentarily. In addition, Metallix also has Sonic's astounding kineticism, precision and reaction time to match his speed. He has profound acrobatic skills and agility, along with enhanced reflexes that lets him avoid any incoming obstacles with precise and delicate movements.

Metallix has both impressive durability and physical strength. His frame consists of monocoque titanium that makes him highly resistant to damage, and he has enough strength to tear his own frame apart by hand. In addition, Metallix comes equipped with several extra abilities due to his mechanoid form. These include telescopically extendable limbs, the ability to generate a seemingly impenetrable force-field, and sufficiently sharp claws. Metallix can even channel internal radioactive force within him to produce powerful energy surges, and, when accelerating to maximum speed, surround himself in an energy field that lets him penetrate any substance caught in his path. Plus, by utilizing his jet engine, Metallix can achieve high-speed flight in any environment.

Metallix's arguably most impressive skill is his ability to replicate the abilities and skills of others. By scanning and copying another being's life data, be it either robots or organic creatures, Metallix can immediately and flawlessly mimic other people's skills and abilities, an example being when Sonic accidentally fish a Jaws Badnik, as Metallix, while he gave the alarm, he also copied data from Jaws, learning how to swim.

Being a robotic clone of Sonic, Metallix can imitate several of Sonic's signature techniques. The most prominent of these include Sonic's core offensive maneuver: the Spin Attack, a technique where he curls into a concussive ball or cutting disk and directs himself at his targets. With it, Metallix can shred or burrow through just about any substance given enough speed. Highly adept in Sonic's usage of this technique, Metallix can utilize several variants of the Spin Attack for both ground and aerial maneuvers, including the Spin Dash, Spin Jump, Homing Attack and the Light Speed Attack.

After copying data from the Sword of Chaos, and absorbing 7 Chaos Emeralds, Metallix became near-omnipotent.

Bowser Jr.
Metallix has a high respect towards his creator, Bowser Jr., as he addresses towards him with "Lord Junior". They would often have talks alone, as good friends, occasions on which he can learn about things most robots can't understand, such as souls and Genesis Waves. Despite Metallix's respect towards him, Bowser Jr. sees him as his equal rather than a subordinate.

Sonic the Hedgehog
Sonic is Metallix's organic template. Metallix would often assist Sonic on missions. Metallix believes Sonic and Sally are into an "opposite gender attraction".

Sally Acorn
Metallix is obediant towards Sally unless Bowser Jr. tells him otherwise, an example being going to rescue her against her will, but then accepting his punishment. According to Metallix, Sally is very important for Sonic, as "protecting her will protect [Sonic's] soul". He even goes far enough to say that Sonic and Sally are into an "opposite gender attraction".

Antoine D'Colette
Not much is known about Metallix's relationship with Antoine, only that Metallix knows that Antoine is a general.

Dr. Eggman
Metallix has a desire to do as much harm to Eggman as possible. It is unknown if it is because he was built to be an exact copy of Sonic or because of his respect towards Bowser Jr., but the second option is more probable.

Trivia

 * A theory among fans says that the Metal Sonic is a roboticized Sonic from a timeline in which Eggman managed to defeat Sonic, and then sent him to help his past self. Indeed, Metallix resembles a version of Cyborg Sonic from "Sonic Boom", the only differences being that Metallix has Sonic's Archie counterpart as a template and has red eyes.
 * Metallix also bears a strong resemblance to his Super Mario Bros. Z, the only difference being that NEO! Metallix is good, while SMBZ! Metallix is evil.
 * The Merger Magikoopa confirmed that Metallix is a roboticized Sonic from a timeline in which Eggman managed to defeat the Freedom Fighters.
 * Bowser Jr. aims for Metallix to be the perfect balance between organics and robotics.
 * Metallix believes Bowser Jr. can predict future.
 * Although SEGA Mandates claim there can only be one Metal Sonic, and that one must work for Eggman, Metallix still exists, for the following reasons:
 * "Freedom Fighters NEO" takes place in an Alternate Universe created by a fan.
 * It is in Bowser Jr's nature to cheat the rules of reality ever since the Super Genesis Wave.
 * Metallix likes memes. Evidence is making a parody of the "THIS IS SPARTA!" meme while confronting Scratch and Grounder for the first time,, having a power level of 9999, which is over 9000, and his catchphrase, "I'LL CRUSH YOU!" being popular among the fanbase.
