The New Adventures of Sonic the Hedgehog is an upcoming Canadian-American action-adventure-comedy animated television series based on the Sonic the Hedgehog video game series by Sega, most notably the Archie Comics-published comic book series, also mixing some elements from the Sonic Boom continuity, being a reboot of Adventures of Sonic the Hedgehog. The series is a co-production between Sega of America, DHX Media and Warner Bros. Animation and it will premiere on WB Kids in 2020.

Main

 * Sonic the Hedgehog (voiced by Billy West) - a 15-year-old blue hedgehog with super speed and the leader of the Knothole Freedom Fighters. Sonic has good intentions and is heroic, but can be shortsighted of others' feelings and impatient.
 * Miles "Tails" Prower (voiced by E.G. Daily) - an 11-year-old two-tailed yellow fox who is Sonic's sidekick/best friend, serving as the Knothole Freedom Fighters' technology expert.
 * Knuckles the Echidna (voiced by Jess Harnell) - a 16-year-old red echidna and the muscle of the Knothole Freedom Fighters, being independent, headstrong and serious, yet gullible and short-tempered to a fault.
 * Amy Rose (voiced by Grey DeLisle) - a 12-year-old pink female hedgehog who serves as the Knothole Freedom Fighters' voice of reason, being the more emotionally mature member of the group. She has a crush on Sonic, despite seeming to be more cautious about it like her Sonic Boom incarnation.
 * Sally Acorn (also voiced by Grey DeLisle) - a 16-year-old female chipmunk and the princess of the Mobotropolis, being the strategist for the Knothole Freedom Fighters. Like Amy, she also has a crush on Sonic.
 * Cream the Rabbit (voiced by Andrea Libman) - a 9-year-old female rabbit, being very polite, well-mannered and pure, though she can be childish and naïve. She's Amy's sidekick, who sees her like an older sister.
 * Cheese the Chao (vocal effects also done by Andrea Libman) - a chao who Cream keeps as a pet and often used as a method of attack by her.
 * Antoine D'Coolette (voiced by Scott Menville) - a 19-year-old French-speaking coyote and a faithful and longtime member of the Knothole Freedom Fighters. He is a skilled swordsman, despite being considered an hypocrite, coward and narcissist (specially by Sonic and Knuckles).
 * Bunnie Rabbot (voiced by Tara Strong) - an 18-year-old Southern-accented female rabbit (though partially robotic) skilled in martial arts who desires to be returned to normal. She has a crush on Antoine.
 * Rotor the Walrus (voiced by Dee Bradley Baker) - a 17-year-old walrus and the mechanic of Knothole Village. He provides the Knothole Freedom Fighters with useful inventions and accompanies them on missions.
 * Nicole the Holo-Lynx (voiced by Candi Milo) - an artificial intelligence in the form of Sally's handheld computer who is incredibly versatile and able to interact with and manipulate technological systems, being also able to transform into a holographic 16-year-old female lynx with a Power Ring.
 * Big the Cat (voiced by Bill Fagerbakke) - a 18-year-old cat who is a gentle and easy-going, though somewhat dim-witted, person with a heart of gold, despite being tall and physically strong.
 * Froggy (vocal effects also done by Dee Bradley Baker) - Big's pet frog and best friend, though he has a habit of running off on his own, leaving Big to set off each time to find him.
 * Sticks the Badger (voiced by Kathryn Cressida) - a female badger skilled in the use of boomerangs, being a paranoid individual of wild habits, who enjoys digging through garbage and looking at shiny objects.

Villains
Under construction...
 * Dr. Ivo "Eggman" Robotnik (voiced by Jeff Bennett) - a mad scientist and de facto the antagonist of the series.
 * Orbot (voiced by Rob Paulsen) - Eggman's red orb-shaped robot henchman, being the more formal and blunt of the two, often being totally honest even at Eggman's expense.
 * Cubot (voiced by Tom Kenny) - Eggman's yellow cube-shaped robot henchman, being the more slow and dimwitted of the two, often misunderstanding the meaning of other characters' statements.

Recurring
Under construction...
 * Shadow the Hedgehog (voiced by Jason Marsden) - a black hedgehog capable of super speed and teleportation, being sharp-witted, always on edge and has a strong sense of purpose, willing to accomplish his goals by any means. He's idolized by Dr. Eggman and he's Sonic's archrival.
 * Rouge the Bat (voiced by Tabitha St. Germain) - an 18-year-old female bat who has a weakness for jewels, like the Master Emerald and Chaos Emeralds, which she always obsesses about, also possessing both super-level kicking power and flight..

Minor
Under construction...
 * King Nigel Acorn (voiced by Maurice LaMarche) - the King of Mobotropolis and Sally's father who's seen mainly through flashbacks.

 * The characters' designs are a mix between the Sonic X and the Archie Comics designs.
 * Sonic, Tails, Knuckles and Amy's age is the same as their Sonic Boom counterparts, while Cream is slighty older than her standard counterpart.
