Based on real-life singer Hayley Williams, she is unlocked after successfully singing the song Misery Business (by Paramore) in the vocal career mode. She is a playable character for vocals, guitar and bass and her fretboard is adorned with flames across it and chains down either side. In-game Hayley has a hairstyle named after her and wears a white sleeveless shirt with the word 'RIOT' across it, this is a reference to Paramore's 2007 album 'Riot!'. Her hairstyle appears in Guitar Hero: Metallica where it is known as the 'Jessie' and her top also appears in the game but without the word 'RIOT'. Hayley Williams is the first female character based on a real person to appear in a Guitar Hero game.
