Metal Sonic Troopers are a group that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They were an army of Metal Sonics created by Sir Charles Hedgehog and Rotor to defend Knothole against Dr. Eggman when Sonic was believed to be dead.
When Sonic went missing after the battle with the Xorda, King Maximillian Acorn commissioned Sonic's Uncle Chuck and Rotor to build an army of exactly a hundred Metal Sonics to act as Knothole's defense after Sonic's supposed death. By using the core-data from the original Metal Sonic that Charles had retrieved and adding a more streamlined construction, Charles and Rotor completed the project, but the army was never used as Sonic returned from space before the army could be activated. Sometime later, a mysterious figure (who later turned out to be A.D.A.M.) activated the army and set it loose on both Knothole and Dr. Eggman. The army even injured Hope Kintobor during their assault, resulting in a fight between Sonic and Shadow, both blaming each other over her sustained injury. However, the army was defeated when Shadow used Chaos Control, completely destroying it. (StH: #157, #158, #159)
- The Metal Sonic troopers shared Neo Metal Sonic's design from the video game Sonic Heroes.
- Despite Dr. Eggman claiming that they were second-rate knock-offs compared to his Metal Sonic units, an observational assessment by Mecha stated that the Metal Sonic Troopers were of superior design. (StH: #158)
- After the original Metal Sonic was revived, he mentions that the energy from his shard was used to make the Metal Sonic Troopers.
- Oddly enough, the Metal Sonic Troopers are somewhat copies of the original Metal Sonic Series. Technically, they can exist before and after Metal Sonic's death.
