Sonic the Hedgehog is a character that appears in the Sonic Boom television series. He is Sonic the Hedgehog's counterpart from the Mirror Dimension. Unlike his counterpart, Sonic is a minor and less capable member of Team Sonic.
Sonic is essentially a doppelganger of his Sonic Boom World counterpart and is so identical to him in both anatomy and attire.
Amidst a battle with Eggman's Octopus Bot and Badniks, during which Sonic was in need of help after messing up, Knuckles got transported to the Sonic Boom World by Octopus Bot after he took over for Sonic. Though Sonic failed to save Knuckles due to his clumsiness, Knuckles soon returned to help him battle more Badniks.
As attested by Knuckles, Sonic is the complete opposite of his Sonic Boom World counterpart in terms of personality. Rather than self-confident and athletic, Sonic is a clumsy and rather incapable fool who can trip over himself as easily as he can on a slippery surface. He has an equally enthusiastic and childish attitude. However, he retains his counterpart's heroism and dedication to fight evil.
Knuckles the Echidna
Sonic looks up to his Knuckles the Echidna as his leader and is very enthusiastic about his proclamations. While Knuckles treats Sonic with kindness and support as if he was a younger brother (referring to himself as a "grown-up" in his presence), Sonic does not mind it and is just glad to see him at work.

- This version of Sonic matches Knuckles' envision of Sonic in "Dude, Where's My Eggman?": clumsy and looking up Knuckles as a role model.
