Sonic Underground (1999)

In the electrifying universe of Sonic the Hedgehog's third animated adventure, Sonic Underground, Sonic and his siblings Manic and Sonia form a pulsating rock ensemble. Their melodies, however, mask a deeper destiny - they are the progeny of Queen Aleana, the rightful ruler of Mobius. Vanished by Sonic's nemesis, the nefarious Dr. Robotnik, the queen's absence has left Mobius a desolate wasteland. Now, armed with their metallic medallions of power, Sonic, Manic, and Sonia are propelled into a battle against Dr. Robotnik, his duplicitous henchmen - Sleet and Dingo, and a legion of SWAT Bots. Their mission: restore harmony to Mobius and reunite with their long-lost mother. Will the hedgehog trio triumph over Robotnik's reign of terror? Will they uncover the whereabouts of their missing monarch? The rebellion unravels in Sonic Underground, where every chord strikes a blow for freedom and every episode is a step closer to home.
