Main (a new character to the series),
Knuckles,
Sonic,
Amy and
Tails Sega confirmed various cast and characters for
Sonic Boom on February 25, 2014. On May 29, 2014, Sega announced that Nika Futterman would play the role of Sticks, a jungle badger, who joined the franchise as a major character. Numerous new characters were also created for
Sonic Boom.
Jack Fletcher works as the show's voice director, a role he has also held for the video game series since 2010. •
Sonic the Hedgehog (voiced by
Roger Craig Smith) is Team Sonic's leader in the series, a blue
hedgehog with
super speed. Sonic is good-natured and brave, but can be inconsiderate of others' feelings, sarcastic and impatient. He also enjoys the benefits of being a hero and dislikes competition. Unlike most incarnations, the
Sonic Boom version of Sonic has blue-furred arms and wears a brown neckerchief around his neck and athletic sports tape on his wrists and shoes. •
Doctor Eggman (voiced by
Mike Pollock) is a
mad scientist who is the constant nemesis of Sonic. In this series, Eggman is typically portrayed as an idiotic and egomaniacal person. At times he 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 the island in order to build his own theme park. Despite this, he occasionally makes effort to conform to the Hedgehog Village's rules for his own intentions, with his unsuccessful schemes being considered to be annoyances rather than actual threats. •
Miles "Tails" Prower (voiced by
Colleen O'Shaughnessey) is a two-tailed yellow fox who is Sonic's sidekick and best friend and the youngest of the group. He sports goggles and a tool belt and serves as the group's mechanic and technology expert. Tails' inventions do not always work out as intended, though he is highly competent and self-sufficient in combat. He maintains the same personality overall, though he can be immature and cynical at times. •
Knuckles the Echidna (voiced by
Travis Willingham) is a red
echidna and the nature-loving muscle of Team Sonic, whose redesign for
Sonic Boom is the most drastic of any Sega character altered for the series; Knuckles is physically taller than most versions of the character, appears more muscular and wears sports tape around his hands as opposed to spiked boxing gloves. While his original counterpart is depicted as a reserved and naive figure prone to trickery,
Boom Knuckles is depicted as a brave but dim-witted and incompetent figure with little self-awareness to the annoyance of his friends, though he serves as a source of the series' self-referential humor. •
Amy Rose (voiced by
Cindy Robinson) is a pink female hedgehog who is the peppiest member of the group. Amy wields a giant hammer in battle. Just like her main-series counterpart, Amy has a crush on Sonic. It's seen in the episode that she has a photo of Sonic in her bag. However, unlike her portrayal in other Sonic media,
Boom Amy tries to keep her feelings a secret, and often shows visible embarrassment when those feelings are alluded to. Eggman has referred to her and Sonic as if they were a married couple, and to Amy as Sonic's girlfriend. She is the most emotionally mature member of the group, offering common sense when the rest of the team gets carried away, though she can be temperamental and self-righteous. •
Sticks the Badger (voiced by
Nika Futterman) is a paranoid and feral
badger, skilled in the use of boomerangs and bō staffs, who comes from the jungle. While she is usually depicted as extremely hot-headed as a result, her paranoia does allow her to find solutions to problems more easily. •
Orbot (voiced by
Kirk Thornton) and
Cubot (voiced by
Wally Wingert) are Eggman's robot henchmen. Orbot is red and orb-shaped, while Cubot is yellow and cube-shaped. Neither of them are especially malicious or competent (though Orbot appears to be more intelligent than Cubot by some margin), but they follow through with Eggman's schemes anyway.

shrew who will look up to anyone for any of their positive traits. She also felt sorry for Eggman when he transformed into a creature by becoming angry. •
Charlie (voiced by Kirk Thornton) is a
desert rat and an archaeologist living in Hedgehog Village. Knuckles briefly tries to assist him to make up for a past misdeed, but his frustration at Knuckles' incompetence, which eventually causes him to lose yet another job, drives him to become a villain, equipping himself with an ancient exo-suit. In "It Takes a Village to Defeat a Hedgehog", Charlie is among the villains recruited by Doctor Eggman to join Team Eggman. •

Bill Freiberger) is a chimpanzee resident of Hedgehog Village who hosts his own
late-night talk show with his co-host Wolf Sidekick. •

Sonic Boom dimension and pledges allegiance to Eggman. He most frequently appears in the guise of Eggman's fictional brother, "Steve Eggman". •

Rise of Lyric, he acts as a sea captain and has a strong rivalry with his twin brother Pepper. •
Shadow the Hedgehog (voiced by Kirk Thornton) is an evil black hedgehog capable of super speed and teleportation. Idolized by Doctor Eggman for his popularity within the series, he is much more aggressive and vengeful than other incarnations of the character, considering friendship a sign of weakness and determined to destroy Team Sonic and cause disaster to the world at all costs. In the TV series, Shadow has extended red Markers on both his shoes and gloves and has cow-licked quills like Sonic. •
