Sonic Boom: Season 3

Sonic Boom: Season 3 is the third season of Sonic Boom. It marks the debut of new characters and villains.

Main

 * Sonic the Hedgehog (voiced by Roger Craig Smith) – The protagonist of Sonic Boom and the leader of Team Sonic, Sonic is a fifteen-year-old blue hedgehog with the ability to run at supersonic speeds. While having a good heart and good intentions and is very benevolent, Sonic can be shortsighted of others' feelings and be rather impatient. He also enjoys his status as a hero and dislikes competition. Unlike most incarnations, this version of Sonic has blue-furred arms and wears a brown neckerchief around his neck and athletic sports tape on his wrists and shoes.
 * Miles "Tails" Prower (voiced by Colleen O'Shaughnessey) – An eight-year-old yellow fox, Tails is Sonic's sidekick. Sporting two tails, Tails is able to use them to achieve flight like a helicopter. He wears goggles and a tool belt, and serves as Team Sonic's mechanic, pilot, and technology expert. Confident in his abilities, Tails spends much of his time tinkering with inventions meant to make life easier, although they do not always turn out as expected. He maintains the same overall personality as his game counterpart, though he can be blunter and more openly skeptical.
 * Knuckles the Echidna (voiced by Travis Willingham) – A sixteen-year-old red echidna from Angel Island and the last of his kind. He serves as the muscle of Team Sonic, capable of smashing boulders and asteroids to pieces with a single punch. Whereas other versions of Knuckles have a history of being gullible, this version of Knuckles is dimwitted, clueless and often annoys his teammates with his low wit. However, he is very loyal and loves nature. Out of everyone on Team Sonic, Knuckles received the most drastic redesign for the series: Knuckles is considerably taller than most versions of the character, appears more muscular, and wears sports tape around his hands as opposed to spiked boxing gloves.
 * Amy Rose (voiced by Cindy Robinson) – A twelve-year-old pink female hedgehog, Amy is the peppiest member of Team Sonic and Sticks' best friend. She serves as the team's organizer and archeologist, and wields a giant hammer, which is her most prized possession, in battle. Amy has a crush on Sonic, but is cautious and shy about admitting it, unlike other versions of her. This has not stopped other characters from pointing her attraction to Sonic however. She is more emotionally mature than her friends, often offering common sense when the rest of the team gets carried away. Her design is overall the same, except for her clothes, which are now more adventure-orientated.
 * Sticks the Badger (voiced by Nika Futterman) – An orange and brown free-spirited badger that comes from the jungle. She is Amy's best friend. She is an efficient combatant and is skilled in the usage of boomerangs and other weapons of her own design. Sticks is a paranoid individual of wild habits, who enjoys digging through garbage and looking at shiny objects. While she may at times seem off-kilted, obtuse, mental and just plain nutty, her madness often proves correct and will occasionally stray into genius, allowing her to find solutions that no one else could have thought of.
 * Shadow the Hedgehog (voiced by Kirk Thornton) - A powerful black hedgehog capable of super speed and teleportation. He is idolized by Eggman for his popularity within the series, but Shadow does not share his enthusiasm. In Sonic Boom, Shadow is much more aggressive and vengeful than other versions of him; he considers friendship a sign of weakness and is determined to defeat Sonic at all costs. In Season 3, he gotten suspicious of Lina when she first met Team Sonic and planned to get rid of her. After Lina eventually sided to defeat Ulric, he and Lina became new members of Team Sonic.
 * Lina the Wolf (voiced by Lisa Ortiz) - A pale gray wolf dressed in goth and capable of witchcraft and magic spells. In Episode 16, it is revealed that she is a spy of the Black Wizards of Dark Nature to befriend Team Sonic which explained why Shadow is trying to get rid of her. Eventually, she sided with Team Sonic to defeat Ulric and became new members of Team Sonic along with Shadow.
 * Dr. Eggman (voiced by Mike Pollock) – A middle-aged, mad human scientist who is the nemesis of Sonic, his team and the inhabitants of Seaside Island. He resides in a lair off the island's coast. In this series, Eggman is typically rather buffoonish, with his schemes usually being more zany rather than threatening. At times, he even appears to be on friendly terms with the heroes, though this usually leads to some scheme in which he tries to defeat them. His ambitions are to conquer Seaside Island (so he can built his own evil theme park) and the world.
 * Orbot (voiced by Kirk Thornton) – Eggman's red orb-shaped service robot. He is the wiser, blunter, more formal of him and Cubot, often being honest with Eggman at the expense of the latter. He is also the final unit in the Orbot Series.
 * Cubot (voiced by Wally Wingert) – Eggman's yellow cube-shaped service robot. He is the slower, more dimwitted of him and Orbot, which usually leads to him misunderstanding the meaning of other characters' statements. He is also the final unit in the discontinued Cubot Series.
