Sega confirmed various cast and characters for Sonic Boom on February 25, 2014.^[3] On May 29, 2014, Sega announced that Nika Futterman will play the role of Sticks, a jungle badger, who joined the franchise as a major character.^[4][5] Several new characters were also created for Sonic Boom, such as Mayor Fink, Fastidious Beaver and Perci.^[6] 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^[7][8] (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.
• 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's highly competent in his abilities. He maintains the same personality overall, though he can be immature and cynical at times.
• Knuckles (voiced by Travis Willingham) is a red echidna and the muscle of Team Sonic, whose redesign for Sonic Boom is the most drastic of any Sega character altered 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. Whereas other versions of Knuckles have a history of being naive, Boom Knuckles is dull-witted at times which often annoys his teammates.
• 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, but unlike other versions of herself, she tries to keep it concealed. Eggman has referred to her and Sonic as if they were a married couple,^[9] and to Amy as Sonic's girlfriend.^[10] She is the more emotionally mature member of the group, offering common sense when the rest of the team gets carried away.
• Sticks (voiced by Nika Futterman) is a badger, skilled in the use of boomerangs and bō staffs, who comes from the jungle. While she may at times seem crazy, her madness does occasionally stray into genius, allowing her to find solutions that no one else could have thought of.
• Doctor Eggman (voiced by Mike Pollock) is a mad scientist who is the constant nemesis of Team Sonic and the inhabitants of Bygone Island, residing in a lair off the island's coast. In this series, Eggman is typically portrayed as being idiotic, with his schemes being considered annoying rather than dangerous. 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.
• Orbot (voiced by Kirk Thornton) is Eggman's red orb-shaped robot henchman. He is the mature, more outspoken of the two, often being totally honest even at Eggman's expense.
• Cubot (voiced by Wally Wingert) is Eggman's yellow cube-shaped robot henchman. He is the childish, more gullible of the two, often misunderstanding the meaning of other characters' statements.

Awards and nominations

Video games

A pair of video games that serve as prequels for the series were released for the Wii U and Nintendo 3DS systems in November 2014.^[77] The Wii U version, Sonic Boom: Rise of Lyric, was developed by Big Red Button Entertainment and the 3DS version, Sonic Boom: Shattered Crystal, by Sanzaru Games. The games were announced alongside the TV series' first trailer on February 6, 2014, and serve as prequels to the series. Rise of Lyric sees players alternate control between Sonic, Tails, Knuckles and Amy. The game utilizes each of their abilities—Sonic's speed, Tails' flight, Knuckles' strength and Amy's agility—allowing two players to play cooperatively and four players competitively. Shattered Crystal lets players control Sonic, Tails, Knuckles and Sticks and places more emphasis on platforming and puzzle-solving than the more adventure-oriented Rise of Lyric. Rise of Lyric received absolute critical lambastment and became notable for its mostly negative reception from critics, who criticized its gameplay, story, low quality visuals, level design and glitches.^[78] On June 20, 2014, it was confirmed that both games would be released on December 18 in Japan under the name of Sonic Toon.^[79] A third game, Fire & Ice, was for Nintendo 3DS in September 2016.^[80] Sonic Dash 2: Sonic Boom, a follow-up to the free-to-play Sonic Dash, was released on Android devices on July 1, 2015.^[81] Since her debut in the show, the character Sticks has gone on to be featured and mentioned in peripheral Sonic titles that are not part of the Boom brand, such as Sonic Runners, Mario & Sonic at the Rio 2016 Olympic Games,^[82][83] and Sonic Frontiers.

Books

In early 2016, a series of children's books adapted from several Sonic Boom episodes were released in France by Hachette under the Bibliotheque Verte collection.^[84]

Comics

A comic based on the new franchise by Archie Comics was released beginning in October 2014, with Ian Flynn as the writer and Evan Stanley as the artist, similar to Archie's long-running Sonic the Hedgehog comic series.^[85] Several issues were also written by TV series showrunner Bill Freiberger.^[86] Jesse Schedeen of IGN rated the first issue of the comic a 7.2 out of 10. He commended Flynn for not having relied on nebulously-defined "trendy, modern humor or dialogue" in the comic's presentation and also appreciated the fourth-wall humor and "clean, expressive" art style. Schedeen did, however, find the plot fairly disjointed and possessing little coherent structure and he criticized Sticks, whom he considered a needless exposition device.^[87]

The Sonic Boom comics were featured alongside Archie's Sonic the Hedgehog, Sonic Universe and Mega Man comics, as well as various other Sega and Capcom video game series as part of the 2015 Sonic/Mega Man crossover "Worlds Unite", with issues #8-#10 forming parts 2, 6 and 10 of the story.^{[88][89][90][91][92]} The series concluded with its 11th issue in September 2015, though stories featuring the characters continued to be printed as part of the Sonic Super Digest and Sonic Super Special Magazine books.^[93][94] Flynn and Stanley later began writing for the television series during its second season.^[95]
