In the beginning prior to Super Mario Bros. Z, Mecha Sonic was born Metal Sonic, as told in episode 4. He was created by Dr. Eggman, after his attempts of destroying Sonic by using robotic models of Sonic failed indistinctly. Sonic fought him countless times, and was defeated. Metal Sonic would return a lot more stronger after each defeat. One night at the Death Egg, things took a turn for the worst, Metal Sonic fused with the previous robot Sonic models and became Turbo Mecha Sonic.

When Dr. Eggman discovered this, he threatened to shut him down for his rebellion. Mecha Sonic went berserk and destroyed the Death Egg, causing it to crash in Mobius. When he emerged from the ruins, he became a bloodthirsty mechanical demon with a lust for power. He started by killing Tails, Amy, Knuckles, Cream, Cheese and the majority of the innocent animals of Mobius while in search for the Chaos Emeralds. When he defeated Sonic, he took his Emerald and prepared to turn in his ultimate form, but thanks to Shadow, it was prevented. However he escaped to the Mushroom Kingdom to find the Emeralds. He was also directly responsible for Shadow's current personality, as it came about as a result of his slaughtering of Rouge and Omega.

In Episode 3, he fights and easily defeats Yoshi, but he did not finish him since he felt Sonic and Shadow's presence in the Mushroom World. In Episode 6, he defeats the Koopa Bros and steals their Emerald and brutally destroys the Axem Rangers X, after fusing himself with four of the Emeralds becoming Semi-Super Mecha Sonic. He completely destroyed Yoshi's Island, but not before the Emeralds are taken from him by Mario and Sonic.

In Episode 7, he assaults Mario and Sonic, but when he is in the Minus World he cannot use Chaos Control. The heroes escape before he could incinerate them.

More facts are known in future episodes. Alvin has confirmed that he will collect all of the Chaos Emeralds.
