Sonic the Hedgehog is a character that appears in the Sonic Boom series. He is an anthropomorphic hedgehog and Sonic the Hedgehog's counterpart from the Mirror Dimension, where he is a minor and less capable member of Team Sonic.
Sonic is essentially a doppelganger of his Sonic Boom World counterpart. As such, he is an anthropomorphic hedgehog with blue fur covering most of his body, and peach skin that covers his muzzle, insides of his ears and front torso. He is rather slim, with reasonably long arms and legs, along with visible shoulders, giving him a lanky appearance. He has a fairly round head with six thick quills protruding from the back of his head and small, triangular ears on top of his head. He also has cowlick-like spikes that sticks out from his top and lower head quills, two spines protruding from his back behind his shoulders, and a short tail. He also has conjoined green eyes and a fairly long black nose. He also has a visible neck, although it is usually covered by his attire.
For attire, Sonic wears a pair of white gloves with cuffs and a pair of red sneakers with white cuffs, gray soles, and a rectangular gold buckle on top. He also has white sports tape wrapped around the palms of his gloves, the heels of his sneakers, and his lower forearms and legs. Finally, he sports a brown neckerchief
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 a horde of Crab Bots.
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.
