Neo Metal Sonic

Metal Sonic assumed this form as he sought to defeat Sonic on his own and conquer the world himself, as he held the "key to destroy the world." To this end, he betrayed Dr. Eggman, took control of the Eggman Empire and began seeking out the data needed for him to transform into Metal Overlord. To achieve this, Neo Metal needed to copy the lifeform data of other beings. Using his shapeshifting abilities to pass as the real Sonic, Neo Metal would also kidnap Froggy and Chocola in order to obtain their data on Chaos as well.

Appearance: Neo Metal Sonic shares some distinctive traits with his base form, such as black eyes with red irises, a similar torso with a rocket engine in the center, and the primary blue color with red shoes. There are a number of differences that Neo Metal Sonic features as well. His head has five long quills as opposed to his regular three, with white stripes and markings around his eyes, similar to that of Shadow the Hedgehog. The yellow color in his ears has been replaced with red and his once grey nose is now black.

He also possesses more pronounced body armor, with black and curved shoulder plates, larger gauntlets and leg armor with pointy kneecaps that have white outlines, a plate covering his pelvis and elf-like shoes. He also sports a spiky belt with a black cape that protrudes out of the back of his waist.
