Sonia the Hedgehog

The only female member of the Sonic Underground and the sister of Sonic and Manic. Unlike her brothers, she was raised by an aristocratic foster family, giving her an upper class mentality. She hates getting dirty, is skilled at gymnastics and karate, and possesses superhuman strength, a photographic memory, and the ability to spin in a cyclonic manner similar to the Tasmanian Devil and Espio the Chameleon. Her medallion's string is yellow. Sonia has a pink motorcycle which can travel as fast as Sonic (it was destroyed in the 36th episode). Sonia develops an attraction towards Knuckles during the Flying Fortress saga of the series. She was also played by Jaleel White. Her singing voice was provided by Louise Vallance.
