Sonic Underground

Three royal hedgehog siblings — Sonic, Sonia, and Manic — were separated at birth to protect them from the tyrant Dr. Robotnik, who rules Mobius with an iron fist. Reunited as a traveling rock band, they search for their missing mother Queen Aleena while fulfilling an ancient prophecy that will end Robotnik's regime. Each sibling wields a magical medallion that transforms into both a weapon and a musical instrument.
