All living things kneel before your master!
— Neo Metal Sonic, Sonic Heroes
Neo Metal Sonic (ネオメタルソニック Neo Metaru Sonikku?) is a transformation that appears in the Sonic the Hedgehog series. He is one of Metal Sonic's transformations which he once used to disguise himself as Dr. Eggman and to copy the data of whom he fought against in order to make himself more powerful.
Neo Metal Sonic shares some distinctive traits with his normal form, such as black eyes with red irises, similar torso with a rocket engine, and the primary blue color with red shoes, but he has a number of differences too. 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.
He also possesses more pronounced body armor, with black and curved shoulder plates, larger gauntlets and leg armor with pointy knee caps that have white outlines, a plate covering his pelvis and elf-like shoes. He also sports a spiky belt with a black cape that protrudes out of the back of his waist.
Some time prior to Sonic Heroes, Metal Sonic assumed this form as his frustration over his constants defeats by Sonic the Hedgehog's hands reached the boiling point. Consequently, Metal Sonic decided to defeat Sonic on his own and conquer the world himself. To this end, he betrayed Dr. Eggman, took control of the Eggman Empire and began seeking out the data needed for him to transform into Metal Overlord.
To get the data he needed, Neo Metal Sonic elaborated a plan where he would send Team Sonic on a wild goose-chase to destroy "Dr. Eggman's" newest weapon. Then, by using his form's shapeshift-abilities, Neo Metal Sonic masqueraded as a robotic Dr. Eggman and fought Team Sonic on various occasions while copying their data without them knowing. At some point, Neo Metal Sonic used his shapeshifting abilities to pass as the real Sonic, and kidnapped Froggy and Chocola in order to obtain their data on Chaos.
While Neo Metal Sonic only intended to involve Team Sonic, Team Rose, Team Dark, and Team Chaotix entered the conflict as well. This proved however to work in the favor of Neo Metal Sonic, as he continuously faced the teams while masquerading as Dr. Eggman, and began copying their data as well, making himself even more powerful than he planned to.
At the time Team Sonic and Team Dark defeated the Egg Albatross, Neo Metal Sonic had successfully copied Team Sonic's and Shadow's data, and when Team Rose defeated Neo Metal Sonic in the Egg Emperor, he had copied Chaos' data as well, making him release Froggy and Chocola from captivity.
With all the data he needed, Neo Metal Sonic revealed himself to the heroes and destroyed the Final Fortress' tower before using the debris to transform into Metal Madness and later Metal Overlord. However, he was later defeated by Team Super Sonic and reverted to Neo Metal Sonic, and then back to his original form.
Powers and abilities
Neo Metal Sonic is, like his normal form, able to scan the life data of other life forms, allowing him to copy and replicate others' attributes and abilities flawlessly. Due to his actions throughout Sonic Heroes, it can be assumed that, by the beginning of the last story in the game, he possessed the abilities of all the teams, plus those of Chaos itself.
Neo Metal Sonic has the power to shapeshift, allowing him to change his appearance and body structure. When shapeshifting, he turns into a puddle of liquid metal and then emerges in a new form. This allows him not only to perfectly imitate the appearance of organic creatures, but also the appearance of robots as well, such as fake Dr. Eggman robot copies, though Tails could tell it was not an Eggman robot. He can also safely contain creatures such as Froggy and Chocola inside of himself until he had copied Chaos' data.
As demonstrated when he first revealed himself, Neo Metal Sonic can create lightning bolts from his hands, launch them into the sky and then bring it back down with enough power to blow up the Final Fortress' largest tower. He can also manipulate outside elements through unknown means to rebuild himself, such as when he used the debris from the Final Fortress' tower to rebuild himself into Metal Madness.
By combining the data from Team Sonic, Team Dark, Team Rose and Team Chaotix with the data from Chaos, Neo Metal Sonic is able to rebuild himself into a much stronger form called Metal Madness. In this form, Neo Metal Sonic's strength and power are highly increased and he gains new abilities and weaponry, such as launching the spines on his back which will sprout into a sharp spike formation, a large flamethrower, missiles which can trap his enemies in crystal cages, and a powerful sweep with his tail.
Neo Metal Sonic briefly assumed this form when he tried to transform into Metal Overlord. During this time, he fought Team Rose, Team Dark and Team Chaotix, before he finally transformed in Metal Overlord.
After completing his transformation as Metal Madness, Metal Madness grows a pair of mechanical wings on his lower body, becoming Metal Overlord. In this form, Metal Overlord is nearly invulnerable and is powerful enough to fight on par with Super Sonic, Super Knuckles and Super Tails. He is capable of flight and is strong enough to throw entire battleships. As Metal Overlord, he can fire a barrage of crystal pillars from his torso, launch the spikes on his back as homing missiles, fire crystal encagíng missiles, and perform Chaos Control.
After Metal Overlord had finished his transformation, he flew into the skies, but was pursued by Team Super Sonic. Despite his overwhelming power Metal Overlord was defeated by Team Super Sonic and reverted to Neo Metal Sonic, and then his original form.
In other media
In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, an army of Neo Metal Sonic robots, called the Metal Sonic Troops, appeared. These robots were created by Sir Charles Hedgehog and Rotor to serve as protectors of Knothole after Sonic was lost in the battle with the Xorda. While they were never activated by their creators when Sonic returned, A.D.A.M. managed to assume control of them and send them on a rampage against Knothole and Dr. Eggman. The entire army was destroyed however, when Shadow the Hedgehog used Chaos Control.
In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, Neo Metal Sonic is a transformation of Metal Sonic. Much like in the games, Metal Sonic first became Neo Metal Sonic when he took over the Eggman Empire. However, he lost that form after he was defeated by Team Sonic. Metal Sonic later became Neo Metal Sonic again with Dr. Eggman's aid for the purpose of aiding Eggman during his war with the Resistance, but was completed too late. Armed with Eggman's bio-data however, Neo Metal Sonic set out to conquer the world on behalf of his creator after he went missing.
