Manic the Hedgehog

You may be looking for the article on King Sonic's son from the Mobius: X Years Later universe - Manik Hedgehog. Manic the Hedgehog is the brother of Sonia the Hedgehog and Sonic the Hedgehog from the Sonic Underground reality. Due to the threat of Dr. Robotnik, Manic was left on a doorstep by his mother Queen Aleena but stolen from his intended home by the thief Farrell, who raised Manic like a son. After being reunited with his siblings, Manic would engage Robotnik in battle many times. On one occasion, the trio would team up with Sonic Prime and Zonic to stop the threat of Giant Borg. Manic and Sonia freed Evil Sonic, another version of their brother, from jail after Robotnik imprisoned him. For helping Robotnik get the components of Giant Borg in the first place, Evil Sonic was then taken into custody by Zonic, who left Manic and his siblings to continue their fight. (SSS: #10)
