Metal Sonic

Metal Sonic stands in front of you, ready to destroy you if necessary

He is an evil, ultra-high performance, very advanced Badnik version of Sonic the Hedgehog that was created as a secret weapon by Dr. Eggman for the sole purpose of destroying the blue hedgehog. Modeled with extreme accuracy after Sonic, Metal Sonic not only resembles his organic doppelgänger, but can also imitate his moves and achieve speeds matching and even exceeding the hedgehog's own. The brainchild of Eggman, he is by far his greatest creation.

While usually serving as Eggman's obedient and silent enforcer, Metal Sonic is an intelligent robot with a very dark side. A cold-hearted, aggressive, and ruthless killer, he is obsessed with proving his superiority to Sonic and eliminating him for good to the point where he has rebelled against Eggman more than once to achieve his goal. However, he always fails in the end, only to later return more powerful than before. To this day, Metal Sonic remains one of Sonic's most dangerous foes.
