Sonic's proportions would change for the release of Sonic the Hedgehog 2 on the Mega Drive; Sonic's head to height ratio was changed from 1:2 to 1:2.5. For the 1998 release of Sonic Adventure, Sonic was redesigned by Yuji Uekawa as a character with longer legs and a less spherical body, longer and more drooping quills, and green-colored irises. For the 2006 game, Sonic was redesigned to make him look adult-like and taller to appeal to the next generation players. This was also done because Sonic would interact with humans more often and his design was supposed to fit. An alternative "Werehog" form was introduced in Sonic Unleashed, placing more emphasis on Sonic's melee skills rather than speed. Although Tetsu Katano acknowledged the large negative fan response to the Werehog, he believes it could return in a future game. Bob Raffei, CEO of Sonic Boom developer Big Red Button, stated that Sonic Boom Sonic is "very different... both in tone and art direction." Voice portrayal Sonic originally had a few voice samples in Sonic CD, with designer Masato Nishimura providing the voice. Sonic's first true voice actor was Takeshi Kusao for the arcade game SegaSonic the Hedgehog, with Junichi Kanemaru continually voicing the role beginning with the release of Sonic Adventure. Kanemaru also voices Sonic in Sonic X, Sonic Boom, and the Japanese dub of the Wreck-It Ralph films. In Sonic Unleashed, Sonic was voiced by Tomokazu Seki while in Werehog form. Jaleel White voiced the character in the DiC animated series Adventures of Sonic the Hedgehog, Sonic SatAM, and Sonic Underground. Sam Vincent provided his singing voice in the latter DiC cartoon. Starting with Sonic Adventure, Sonic was voiced in English by Ryan Drummond. Drummond was replaced by Jason Griffith starting from Sonic X, with Griffith voicing Sonic within the games starting with Shadow The Hedgehog in 2005. Griffith was replaced by Roger Craig Smith, starting with Sonic Free Riders and Sonic Colors. Smith announced on his Twitter account on January 29, 2021, that he would no longer voice Sonic, with his departure confirmed by Sega the same day. On May 26, 2021, Smith and Sega confirmed that he was voicing Sonic once again. Ben Schwartz voiced Sonic in the 2020 feature film and reprised his role for its 2022 sequel.
