From the SSX 3 bio:

Allegra has always been a rebel. She is renowned for her jibbing talents, as much as pizza-faced punks everywhere worship her for being the ultimate boarding 'Betty'. The best description of Allegra? Fresh. She is the real thing, and shows it with the drive of an olympic athlete mixed with a healthy blast of teen enthusiasm. Once a girl simply content to ride with the boys, she now leaves them behind in a cloud of snow.
