Sonic the Hedgehog is the main protagonist of the Sonic Boom series. He is an anthropomorphic blue hedgehog gifted with super speed who fights Dr. Eggman and other forces of evil alongsideTeam Sonic as their leader. He's also the Pentagonist in the Katie Sandow's Adventures.
Sonic retains most of the appearance from his main series counterpart, but has a few physical and clothing differences. He is much slimmer and taller, with longer arms and legs, which gives him a lanky appearance. His quills are also slightly messier, having some cowlick-like spikes that sticks out from his top- and lower quills, and his arms are covered completely in blue fur, as opposed to being skin-colored.
For attire, Sonic wears a pair of white gloves with cuffs and a pair of red sneakers, which has white cuffs, grey soles, and a large, rectangular gold buckle on the top. Both of his gloves and sneakers have white sports tape around them, which is wrapped around his palms, the lower half of his arms and legs, and the heels of his sneakers. Finally, he sports a short brown neckerchief around his neck.
- Sonic reveals to have an alien in his basement named Roger but, Sonic NEVER uses him as such.
