Hyper Metal Sonic (ハイパーメタルソニック Haipā Metaru Sonikku?), or just Metal (ーメタル Metaru?) for short, is one of the main antagonists in Sonic the Hedgehog: The Movie and serves as the primary villain and Sonic's rival in the second part of the film. He is a robot created by Doctor Ivo Robotnik in the image of the doctor's greatest adversary, Sonic the Hedgehog, with the purpose of defeating Sonic and destroying the Land of the Sky.
He is infused with Sonic's life data (personality and memories) to be as formidable in battle as the real Sonic, making him a near-perfect duplicate of the blue blur. This however created a mind link between Metal and Sonic, allowing them to hear each other's thoughts. This also gave Metal traits of the real Sonic's personality and habits, which eventually lead to him sacrificing himself to save the lives of the President and Old Man Owl.
Hyper Metal Sonic was created by Doctor Ivo Robotnik in the very center of his capital, Robotropolis. Constructed to be the doctor's greatest creation, Metal's purpose was to destroy the real Sonic for good, and help him take complete control of Planet Freedom, by destroying the Land of the Sky. After Metal's body was fully constructed, all that Dr. Robotnik needed to finish his invention was to complete Metal's AI by infusing it with Sonic's life data in order to make it the ultimate fighting machine. To do so however, he needed to get the data by downloading it from Sonic himself.
In order to do so, Dr. Robotnik formulated a plan where he would trick Sonic to come to Robotropolis in order to shut down the Robot Generator, a machine that could eventually destroy Planet Freedom, but in fact served as the device for which to download Sonic's life data into Metal.
Dr. Robotnik's plan eventually worked out perfectly and Metal sprung to life once the download was complete. Not long after coming online, Metal went and faced the real Sonic, and eyed him in silence, while Sonic, Tails and Knucles were shocked to see Sonic's robotic copy. Metal soon after briefly protected Dr. Robotnik as Sonic charged at him, and Sonic challenged Metal to battle in order to save Dr. Robotnik's hostage, Sara. After briefly building up power for the confrontation, Metal faced Sonic in a high speed battle, and proved himself to be more than a match for the real Sonic, and managed to overwhelm him in both strength and speed. Metal's battle with Sonic eventually led to the outside of Robotroplis, where Metal managed to defeat Sonic, by knocking him off a mountaintop, and believed him to be dead.
Following the defeat of Sonic, Metal began following Dr. Robotnik's orders and headed to the capital of South Island to destroy any resistance. Along the way, due to being influenced by Sonic's memories and thoughts, Metal stopped by Sonic's and Tails' home, where he met Old Man Owl and forced Sonic's favorite clothes on him, before continuing to South Island.
Once on South Island, Metal began a destructive rampage throughout the city, before heading off again. By instructions from Dr. Robotnik, Metal headed to a glacier which anchored the continents to the planet, and began drilling a tunnel deep into this glacier, with the purpose of releasing a pocket of magma which would make the glacier melt and cause the continents to shift and be hurled into the atmosphere.
After drilling into the magma pocket, Metal saw Sonic coming and launched an unsuccessful surprise attack from below. Face to face with the real Sonic, Metal announces (through beeps and buzzing) that there could not be two Sonics on this planet, and that one of them had to go. Sonic agreed to the terms, and Metal and Sonic faced each other in a long and intense battle between two opponents of equal might.
As the two of them continued to clash, it became apparent to the both of them that they could read each other's moves due to them sharing the same thoughts, and as such, neither of them could gain the upper hand on one another. Their battle was temporarily interrupted by the untimely arrival of Dr. Robotnik and Sara, as they crashed into the Egg Mobile, but they soon after resumed their fight.
The battle between Metal and Sonic grew increasingly fiercer as the two of them literally tore apart the icy wasteland in the wake of their fight, with Metal hitting Sonic hard and the other way around, but they could still only fight to a stalemate. Eventually however, Metal managed to gain the upper hand, as Sonic began to become exhausted from their prolonged battle. As Metal held Sonic in a chokehold and prepared to finish him, Tails used his navigator to overload his system by assimilating Sonic's personality. As Metal began to malfunction, Sonic took the opportunity, and Metal received a direct hit from his Spin Dash, which knocked him into the distance and inflicted major damage.
Metal returned soon after however to prevent Sonic and Tails from saving the President and Old Man Owl from a crash landing in the President's personal ship. Sonic told Metal to move aside, but Metal ignored his pleas. After Dr. Robotnik prevented Tails from overloading Metal's system once again, Metal tried to resume his fight with Sonic. As their fight continued however, Metal's damage became increasingly more extensive, and Metal found himself overwhelmed by Sonic, and crashed into the windshield of the president's ship. As the ship was about to explode however, Sonic's personality began to overtake Metal's programming and Metal saved the President and Old Man Owl.
After saving them, Metal started to malfunction again, which caused him to be knocked over the side of the cliff by falling debris, into a lava pit. Heavily damaged and nearly unable move, Metal saw Sonic trying to rescue him, and began crawling towards Sonic. To Sonic's surprise however, Metal refused Sonic's rescue and announced to him that "There is only one Sonic...", as Metal now realized that Sonic was the only one of them that could remain in this world. Accepting his fate, Metal allowed the rising lava to consume him, where he melted into slag and perished.
After Metal's demise, Dr. Robotnik planned to build a superior version of Metal, as he still had the CD with Sonic's life data, but the CD itself was shortly after destroyed by one of his own faulty missiles.
