All of the medallions can be used as laser guns . The three use the amulets not only to fight Robotnik's forces but to also as instruments for their underground rock band, "Sonic Underground ." </P> <Ul> <Li> Sonic (the) Hedgehog: The lead singer of many songs performed by the Sonic Underground .

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 turns into a keyboard, which can fire laser blasts from one end, or create a pink mist when the keys are played . Sonia has a pink motorcycle which can travel as fast as Sonic's running and Manic's hover board (it was destroyed in the 36th episode).
