Two traitors, one battle, no regrets!

Jet vs Fiona

Jet is the 14-year-old hawk leader of the Babylon Rogues, and is often nicknamed the "Legendary Wind Master" due to his mastery of Extreme Gear. He's Sonic's most potent rival in Sonic Riders, and he uses a Type-J board that allows him to reach high speeds. Jet also possesses a mysterious "control box", passed down from his ancestors, that is said to awaken the fabled Babylon Garden. Only the power of the Chaos Emeralds can activate its fabled power. Jet, along with the rest of the Babylon Rogues, were originally part of the Battle Kukku Army, but betrayed the team for there own purposes.

Fiona was one of the many victims of Dr. Ivo Robotnik's rise to power, and as a child she was left in prison, abandoned by Sonic the Hedgehog and other Freedom Fighters, and as a result held a grudge against them, with time developing the darker traits of her personality. Upon escaping, Fiona led a life of treasure hunting and other petty crimes, until, following Sonic's apparent death, she attempted to turn over a new leaf by joining the Knothole Freedom Fighters, and even began a relationship with Sonic following his return from space. With time, however, Fiona gravitated back towards her old ways, and ultimately decided she preferred the darker side of life. To this end, Fiona fell in love with Sonic's Anti-Mobius counterpart Scourge the Hedgehog, becoming his girlfriend, and later Queen of Moebius itself following Scourge's takeover, and became a member of the Suppression Squad.
