Knuckles Metallix

Almost as soon as the Metallixes had been decommissioned Grimer was prepared to restart the project. He claimed the problem was that a design based on Sonic was unstable but they now had a new enemy just as powerful as Sonic to beat. The design based on Knuckles never saw the light of day whilst Robotnik was still emperor but once he had lost his power and been kidnapped by the Drakon Empire he took to drastic measures.

The Emperor Ko-Door challenged Robotnik to provide a champion to fight Sonic in a trial to the death which they would use to decide weather or not Sonic was guilty of attacking a Drakon Sentinel in the Aqautic Ruins Zone. Robotnik turned to Grimer and created a new range of Metallixes. These newer designs may not be as sleek and fast as the original but had lightning fast reactions and impressive strength that caught Sonic off guard. Not only did the metallix successfully knock Sonic out and kidnap him for trial on their first encounter but it squarely smashed Sonic in a dual to the death in the arena. Robotnik had suggested that he let Metallix become a temporary Prosectioner for the trial. If it hadn’t been for Tails who helped Sonic escape and crushed the Metallix beneath a bulkhead door, Sonic would have been killed. Despite Tails interference Ko-Door ruled that Sonic was innocent and refused a retrial. Despite his anger Robotnik was later seen to be developing more of these Metallixes in his base on Flickies Island but fortunately Robotnik never used them.

Grimer was obvious proud of his creation and later used one to kidnap Sonic, squarely beating the hedgehog in a match. Fortunately for Sonic he was released with no memory of the encounter and fake rubble suggesting he had beat it, allowing his ego to remain intact.
