Sonic's the name, speed's my game!
―Pre-battle intro quote

Sonic is a playable character in the fighting video game, M.U.G.E.N Trilogy. He was confirmed along with many other characters who appear in Super Smash Bros. Brawl on March 20, 2015. Jun'ichi Kanemaru (Japanese) and Roger Craig Smith (who also voiced Chris Redfield, English) provide the role for Sonic in this fighting game, using voice clips from Super Smash Bros. 4 and Ultimate.


Sonic is a 15-year-old anthropomorphic hedgehog who, as his name suggests, is capable of running at supersonic speeds. He is 3 ft, 3 in (1 m) tall, weighs 77 lbs (35 kg), and has large quills, blue fur, and green eyes. Sonic also wears a pair of Power Sneakers alongside a pair of white gloves.

The self-described "fastest thing alive," Sonic is confident, quick-witted, carefree, virtuous, and adventurous to the point that he hates being constrained, yet he can also be impulsive, hot-headed, snarky and cocky. As a result of his love for freedom, Sonic always campaigns to stop subjugation of any kind, most notably the plots concocted by his arch-nemesis, Dr. Ivo "Eggman" Robotnik.

Sonic gathers golden rings for energy, and when he collects the seven Chaos Emeralds, he can transform into Super Sonic, which grants him flight and invincibility so long as he has a sufficient number of rings. Initially, early Western profiles sometimes portrayed Sonic as being from the fictional planet Mobius. However, Japanese profiles (which Western territories would follow starting with Sonic Adventure) and Yuji Naka, the former head of Sonic Team, have since stated that his birthplace is Kiritimati (also known as Christmas Island), one of the numerous atolls that comprise the real world sovereign state of Kiribati.

Starting in the year of 2007, Sonic is the longtime rival of Nintendo's Mario where they starred in a crossover video game, Mario & Sonic at the Olympic Games for the Nintendo Wii and DS game systems. Later on, he and Mario would continue appearing in later crossover games such as Super Smash Bros. Brawl, Mario & Sonic at the Olympic Winter Games and many more.
