The Werehog debuted in Sonic Unleashed, released by Sega in 2008, after Sonic is split by Dr. Eggman and forced to transform at night. In the game's slower beat-em-up stages he stretches his arms, brawls with enemies, and lets out this roar in combat and cutscenes. Fans later ripped the scream for edits and soundboards, pairing the cute franchise image with an unexpectedly savage noise. It survives because that clash is instantly funny and useful for any over-the-top transformation joke.
