Species	Badnik hedgehog

Mecha Sonic is a crossover character from the Sonic the Hedgehog franchise. He is a robot replica of Sonic, similar to Metal Sonic, but usually depicted as bulkier and with less personality, and is sometimes implied to be a series of similar robots rather than a single rebuilt model like Metal Sonic is. Each iteration of Mecha Sonic originally appeared as a late boss in both the 8-bit and 16-bit editions of Sonic The Hedgehog 2 and then appeared as a major antagonist in Sonic & Knuckles and a brief cameo alongside Metal Sonic in Sonic Adventure, with each of the four games using a different design; his sporadic later appearances are usually based off one of these, and are sometimes given model numbers to differentiate from each other.

The 16-bit Sonic The Hedgehog 2 form of Mecha Sonic appears briefly in the Super Mario franchise within the game Mario & Sonic at the Olympic Games Tokyo 2020 as a boss in the Tokyo Sky Flight minigame found in the Story Mode and the Game Room. His boss fight is similar to his one from the 16-bit Sonic The Hedgehog 2, where his sprite is borrowed from, which has Mecha Sonic spinning around in a ball form, then shooting out spikes. As a ball, he homes in on the player, and when he lands, he stands on either the street level or the building as a platform. Both rolled and unrolled forms are vulnerable to shots.
