Dark Sonic, also known as Dark Super Sonic by fans, is a term used to describe Sonic's darker and unnamed super transformation in the anime series Sonic X. The multitude of fake Chaos Emeralds and Sonic's intense anger allowed him to achieve this transformation. Dark Sonic seems to have two forms. During his mid-transformation, he still appears like Sonic but his fur is a dark blue color and has a dark blue aura emitting from his body. In the final phase of his transformation (his full transformation) however, he looks similar to Super Sonic (thus the reason why he is also called Dark Super Sonic), and his back quills are longer, similar to Nazo. He still retains the dark blue aura around him but his eyes have no pupils or irises, his fur is black and his skin is a dark grey color. As Dark Sonic, Sonic demonstrates light-speed movements, high enough to tear through a robot multiple times within a second simply by dashing through it, while not even being visible. He also possesses very high physical strength, enough to make dents in metal and caves in a robot's face with one punch. Dark Sonic seems to relish the prospect of murdering the two prototype Metarex, as shown by his demonic grin and mad cackle. In this form, Sonic's rage is out of control and he has even gained the intention to kill. However, he can still control his actions to an extent, as this form is rooted in the darker aspects of Sonic's natural instincts, including the desire to live, trample and impose over opposition, and on a metaphysical level, the natural occurrence and manifestation of loss, decline, destruction and death. Dark Sonic has the power to defeat the fan made character Sonic EXE.
