Metal Sonic

Metal Sonic thinks of himself superior to the real Sonic and as such has an intense hatred for the Blue Streak and his friends. Unlike the true Sonic, Metal Sonic is also a complete megalomaniac who sees himself as the ultimate life-form and is happy to do whatever it takes to prove it, even being shown on several occasions to betray his own creator in order to achieve his goal. For a short period of time, Metal Sonic was completely deluded in believing that he was the real Sonic until his breakdown and betrayal of Eggman in Sonic Heroes, accepting the fact that he was merely an artificial duplicate of Sonic, a role which he does not seem to care about nowadays, and has accepted his role in Eggman's plots for world domination. After Sonic Heroes, Metal Sonic fully embraced his evil nature and chose to remain with Eggman, determined on killing his benevolent counterpart however he has since come to believe that he is the true Sonic in a different way calling himself "Sonic the Hedgehog PERFECTED", however Metal still held some small belief that he was the true Sonic which was crushed when he dipped his finger in the Metal virus and nothing happened. He also deeply cares about his creator Dr. Eggman willing to sift through the worlds ashes to find him after he disappeared in Forces, carrying out his conquest of the world in his name, and even wearing a "Let's go Dad" T-shirt to support his "father".
