Metal Sonic has gone through insane transformations over the years—from his first appearance in Sonic CD to his super-powered Mecha Sonic form in Sonic 3 & Knuckles, his kaiju-sized Metal Sonic Kai, and his betrayal of Eggman as Neo Metal Sonic in Sonic Heroes. But now, with Sonic Movie 4 confirmed for 2027, Metal Sonic is finally making his big-screen debut—and it looks like he’s leading an army of himself.
In this video, we’ll explore every version of Metal Sonic, including:
- Silver Sonic (Mecha Sonic) – The original 1992 robot
- Metal Sonic Kai – His monstrous transformation
- Neo Metal Sonic & Metal Overlord – When he betrayed Eggman
- Shard – The heroic Metal Sonic
- Emperor Metallix – The Metal Sonic that became an overlord
- Sonic Movie 4 Metal Sonic – What we know so far
With Sonic Movie 3’s post-credits scene teasing a Metal Sonic army, could we be seeing a dystopian future ruled by Eggman and Metal, inspired by Sonic CD and Fleetway’s Sonic the Comic? Could Metal betray Robotnik and lead his own mechanical empire? We break down all the theories and possibilities based on leaked concept art and official hints.
