Sega has unveiled Sonic Boom, a transmedia Sonic 'universe' set to appear across Wii U and 3DS games, a CGI television series and a range of toys.
Most significantly, Sonic Boom features a redesigned roster of characters "inspired by their abilities and unique personalities".
The Sonic Boom video game - the third and final title in a Nintendo exclusivity deal - is in development at California based Big Red Button Entertainment, the studio founded by ex-Naughty Dog veterans Bob Rafei and Dan Arey in February 2008.
The game will serve as a prequel to the TV series, featuring a new, notably taller cast of Sonic characters and a focus on "collaborative gameplay".
Sega claimed at a press event on Thursday that the Sonic Boom game would present a "totally different experience to previous Sonic games", with Sonic's iconic speed featuring alongside the unique aspects of the Wii U and 3DS hardware.
As the debut Sonic Boom trailer below shows, running, exploration and combat elements will combine with a new "Enerbeam tether mechanic" that lets the Sonic cast latch onto beams as they blast through levels.
Meanwhile the 3DS game is in development at another Californian developer Sanzaru Games, which has spent recent years working on the PS3 and Vita ports of the Sly Collection and its companion iOS/Android apps.
The CGI TV series, a collaboration between Sega and French OuiDO! Productions, will comprise of 52 short, 11-minute episodes spanning stories for the full cast of new-look Sonic characters. It's planned to air on Cartoon Network in the US "during the 2014/2015 season".
Both the game and TV series will be distributed in collaboration with a new line of toys in partnership with TOMY, including "plush, action figures, RC, role play, vehicles and novelty".
Sega's chief content officer Hiroyuki Miyazaki said in a statement: "SEGA is constantly looking to feed the appetite of Sonic fans, new and existing alike.
"The various pieces of the Sonic Boom project, such as its unique look, mix of comedy, and action and its focus on the whole ensemble with Sonic as the star, offer another exciting part of that universe for people to explore and enjoy. It will be at once familiar but also new."
Sega first announced a three-game publishing deal with Nintendo in 2013, which included Sonic: Lost World, Mario & Sonic at the Sochi 2014 Olympic Winter Games, and an unannounced third title.
