Dr. Robotnik
With a vast amount of intelligence, Dr. Robotnik is responsible for creating his most deadliest robot ever: Hyper Metal Sonic. By collecting Sonic's data and inputing it into Metal Sonic's memory banks, the Eggman hopes to use his ultimate creation to destroy the Land of the Sky.
Hyper Metal Sonic
Created by Dr. Robotnik, Hyper Metal Sonic was finally completed when it received the life data from his counterpart: Sonic the Hedgehog. Equipped with a turbo thrust engine, Metal is programmed to seek out and destroy Sonic and the Land of the Sky. Since Metal Sonic was programmed with Sonic's data, it knows everything about Sonic, including Sonic's thoughts which almost allows him to predict Sonic's moves.
