Metal Robotnik

"You might have the fastest feet in the world, but now you're just a normal hedgehog! I'll make sure you never make it to Robotropolis!"

- Metal Robotnik against Sonic.

Metal Robotnik (ブラックエッグマン Burakku Egguman, lit. "Black Eggman") is a gigantic robot replicating Dr. Robotnik in the film Sonic The Hedgehog: The Movie who conquers over the doctor's city in the Land of Darkness, Robotropolis.

Past
Metal Robotnik, out of nowhere, conquered Dr. Robotnik's peaceful city, Robotropolis and made it a nightmare. His minions, or as Robotnik calls them, demonic robots, caused Robotnik to flee to the Land of The Sky and search for Sonic and Tails' help.

Welcome to Eggmanland
While in the presidential house, a strange capsule breaks in the building, revealing it's inside. Sara, who wanted a drive, excitedly steps in the pod and messes with the instrumental panel. together with Dr. Robotnik, the capsule closes and flys away.

The duo, Sonic and Tails, travel to the Land of Darkness and eventually find themselves in the ancient city. Hurrying to the Robot Generator they've got too shut down, they instead fall from a mysterious explosion that happened right in front of the two. A cloaked badnik comes closer and closer and speaks to them. Tails assures it's Metal Robotnik, the enemy Dr. Robotnik talked about. Sonic eventually demands him to step out of the way, but Metal Robotnik readies to aim at them. Unfortunately, the two annoy him constantly by moving around the place rapidly. Sonic eventually tries to attack him, but gets heavily hurt by his polymer alloy. Tails zooms up his face and Metal Robotnik tries to punch him, but instead he punches is own face. The two zap away and Metal Robotnik looks for them, but is unable to locate said duo.

Chase
On the highway, Sonic and Tails start to tease him, with Tails making faces and Sonic presumably flipping Metal Robotnik off. Being pissed at the team, he grows bat wings with jets on his back and sets chase and destroys a part of the highway. On it, he tries to shoot Sonic and Tails multiple times and tries to catch up with them. When Tails has trouble catching up, Metal Robotnik tries to catch him, Sonic then grabs tails and speeds up. Metal Robotnik then deploys missiles ahead of Sonic and Tails, making them almost fall off the bridge. Metal Robotnik steps up to them, seeing the two tired on the ground. He shoots them off, at least he thought he did, because they hang on some rails of the highway.

Glue
The two try to tippy-toe away from Metal Robotnik, but he spots them and immediately shoots them, only this time with glue. Tails ultimately gets stuck by some. Sonic tries to save him, but gets attacked by Metal Robotnik's bombs. It creates a giant explosion and attracts Knuckles' attention.

Sonic comes back with a missile, pointing at Metal Robotnik. He gets hit by one and loses a chunk of his face. Sonic, stuck in glue, starts to sink into water as Metal Robotnik approaches. He tries to shoot Sonic, but he eventually gets hit by the treasure hunting Echidna. Being helped from Metal Robotnik's stickiness thanks to Knuckles, Tails rushes over to save Sonic. Wondering how he escaped, Metal Robotnik gets punched by Knuckles. He tries to make him halt, but Knuckles dodges the projectiles. Although, Knuckles eventually does get stuck. When he tries to cover Knuckles in more glue, his bullets are out. He grabs Knuckles, but suddenly Sonic is saved by Tails and cuts Metal Robotnik's hand off, thanks to Sonic's spin move. He then tries to rise up into the sky, running away from the problems he caused, but with the help from Knuckles and Tails, Sonic destroys Metal Robotnik, even by exploding him. His remains then float in the water.

From it emerges Dr. Robotnik and Sara. Dr. Robotnik rages at Metal Robotnik's defeat and swears that something far worse will cause his victory, Sara then hits Dr. Robotnik for his plot and will never forgive him if he touches Sonic.

Sonic VS. Metal Sonic!!
Sonic, Tails and Knuckles are now at the core of Robotropolis and meet Sonic's strange counterpart: Hyper Metal Sonic. After demolishing the Robot Generator and it falling into an abyss, various sparkles and flames appear. From a portal, Metal Robotnik appears, but instead falls apart and unveils Robotnik and Sara in it. Knuckles accuses not only Robotnik for controlling the giant robot but also Sara. She loudly starts to sob.
