The Sonic Boom franchise brought a fresh comedic style to the beloved blue hedgehog universe across its animated television series and tie-in video games. Behind the redesigns and witty scripts stood a seasoned cast of voice actors who defined the eccentric personalities of Team Sonic and their quirky village neighbors.
The primary English voice cast features Roger Craig Smith as Sonic, Colleen O'Shaughnessey as Tails, Travis Willingham as Knuckles, Cindy Robinson as Amy Rose, and Mike Pollock as Dr. Eggman. Directed by voice veteran Jack Fletcher, these performers brought a distinct improvisational energy to the recording booth that set the cartoon apart from mainline Sega titles.
Main Team Sonic Voice Cast
Team Sonic underwent distinct visual overhauls for this spin-off, and their vocal performances matched their new physical traits and comedic tones.
Roger Craig Smith as Sonic the Hedgehog
Roger Craig Smith has voiced Sonic in various media since 2010, but the Sonic Boom iteration gave him room to lean into sharp sarcasm and laid-back banter. Sonic serves as the group's impatient leader, and Smith balances high-energy heroics with dry deadpan delivery when dealing with the absurdities of Hedgehog Village. Beyond Sonic, Smith also lent his vocal talents to minor recurring characters like Dave the Intern and Admiral Beaverton.
Colleen O'Shaughnessey as Miles "Tails" Prower
Colleen O'Shaughnessey brings brains and earnest charm to Tails. In this continuity, Tails functions as the resident mechanic and inventor, though his creations frequently backfire with humorous results. O'Shaughnessey captures his loyal, tech-savvy nature while infusing his dialogue with youthful optimism and occasional deadpan cynicism.
Travis Willingham as Knuckles the Echidna
Travis Willingham completely redefined fan expectations for Knuckles. Moving away from the stoic guardian archetype of past games, the Sonic Wiki Zone details how this version of Knuckles leans heavily into a well-meaning but dim-witted comedic musclehead. Willingham delivers deadpan nonsense lines with total earnestness, turning the character into a primary source of the show's self-referential humor.
Cindy Robinson as Amy Rose
Cindy Robinson voices Amy Rose, who acts as the practical voice of reason for the team. Unlike her romantic obsession portrayed in older titles, Boom Amy tries to conceal her crush on Sonic while maintaining a sharp, structured leadership style. Robinson balances Amy's short-tempered moments with genuine warmth and emotional maturity.
Villains and Supporting Cast Members
The world expanded well beyond the core four heroes, introducing wild new allies and incompetent antagonists voiced by veteran voice industry talent.
Mike Pollock as Dr. Eggman
Mike Pollock reprises his iconic role as Dr. Eggman, though the character received a major personality shift. Eggman functions less as a world-ending dictator and more as an isolated, theatrical nuisance who treats his evil plots like a 9-to-5 job and occasionally hangs out with the heroes. Pollock relishes the comedic writing, delivering dramatic monologues that highlight Eggman's fragile ego. Pollock also voiced supporting locals like Mayor Fink and Fastidious Beaver.
Nika Futterman as Sticks the Badger
Sticks the Jungle Badger is an original addition created specifically for this sub-series. Nika Futterman voices her as a feral, hyper-paranoid survivalist living in the jungle. Futterman's energetic delivery sells Sticks' wild conspiracy theories, which occasionally stumble into actual truths that help the team solve crises.
Kirk Thornton and Wally Wingert as Orbot and Cubot
Eggman's robotic henchmen are brought to life by Kirk Thornton (Orbot) and Wally Wingert (Cubot). Thornton plays the straight man with dry wit, while Wingert handles Cubot's glitchy speech patterns and innocent cluelessness. Thornton also voices the brooding anti-hero Shadow the Hedgehog during his special guest appearances.
Behind the Scenes: Recording and Directing
The creative atmosphere behind the microphones played a major role in how natural the dialogue felt on screen. Voice director Jack Fletcher oversaw the sessions, encouraging actors to play off one another during recording. While many animated shows rely on individual pickup lines, the cast frequently recorded together, allowing genuine comedic timing and overlapping banter to shine through in the final mix.
Frequently Asked Questions

Yes. Shadow appears as a guest antagonist in select episodes, retaining his intense rivalry with Sonic while voiced by Kirk Thornton.
Why did Knuckles sound and look different in this series?
