Trivia

 * Sonic and Fiona for a brief time were a couple in the Archie Sonic comics, until she betrayed the Freedom Fighters and became Scourge the Hedgehog's girlfriend. This is something that will never happen in Sonic Freedom Forever.
 * Unlike in the Archie Sonic comics, Sonic Freedom Forever's version of Fiona is more light hearted and is far more trusting of others, preferring to have friends and being heroic. Also, this version is genuinely in love with Sonic.
