Mecha Sonic, Fictional Fighters Wiki

Mecha Sonic (originally known as Metal Sonic) is a robot created by Dr. Eggman for the sole purpose of destroying Sonic. He serves as the primary antagonist for the first saga of Super Mario Bros. Z. After Metal Sonic was created, he fought Sonic in their first battle, and lost. However, he returned faster and more powerful than ever, but was still beaten. Meanwhile, Metal Sonic sneaked into the Death Egg, combined with all of the other Sonic robots, and transformed into the almighty Mecha Sonic
