And the movie's director revealed on Friday that the film's release will be delayed by three months as they tweak the character.
Following the backlash, Fowler surprisingly took the criticism in stride and indicated they planned to fix the character and make him "the BEST he can be..."
Fans, you can either have a bizarrely human-looking Sonic the Hedgehog this year, or you can have a less odd-looking Sonic the Hedgehog later.
While the titular character will be getting a makeover, Jim Carrey, who plays the famed villain Dr. Robotnik, will be the same.
Fans were particularly upset about Sonic's teeth, Vulture reported. Likewise, one of Sonic's originals creators voiced his concern via Twitter with some of the original images of the live-action version of Sonic, also praising fans for their reaction that spurred the redesign. People were critical of Sonic's odd appearance, looking more like a human/Sonic hybrid than anything resembling the famous character. Granted, that silhouette's an icon for the Sonic series as a whole and it may not indicate what he'll look like in the film.
