Manic the Hedgehog is the brother of Sonia the Hedgehog and Sonic the Hedgehog from the Sonic Underground reality. Manic and his siblings are part of the underground resistance against Dr. Robotnik as well as a musical band.
Before Giant Borg
Shortly after Sonic, Manic, and Sonia’s births, the Underground Zone’s local Dr. Robotnik would seize power of Mobotropolis and convert it into the polluted and metallic city of Robotropolis. A bounty was placed on the children of the queen, and thus Aleena was forced to take them into hiding. Eventually, the Oracle of Delphius appeared before her with a prophesy which foretold that she would have to separate with her children in order save they’re lives. Sending the siblings to three different caretakers, Manic was left on a doorstep but was stolen from his intended home by the thief Farrell, who raised Manic like a son. Manic would learn how to play drums and went off to form a band after meeting Sonic and Sonia. The Oracle of Delphius reappeared to tell the children of they’re origins. Shortly afterwards, Dr. Robotnik captured Farrell, as well as Sonic and Sonia’s guardians and roboticized them. It was then that the three hedgehog children would form an alliance with each other to locate they’re missing mother. (SSS: #10)
Giant Borg's Attack
Manic and his siblings would engage Robotnik in battle many times. Evil Sonic would appear in the Underground Zone on a mission from Robo-Robotnik to recover the Giant Borg. Believing Underground Sonic also possessed a piece of the Giant Borg; he located and interrogated him and his siblings. The evil hedgehog departed only for two new Sonics to appear: Prime Sonic and Zonic. Manic, Underground Sonic and Sonia mistook Prime Sonic for Evil Sonic until the two new hedgehogs explained who they are. Zonic would remark how he had a lack of data on Underground Sonic and the Sonic Underground dimension and would request an explanation of the Zone’s history. (SSS: #10)
Manic, Sonia and Underground Sonic would then team up with Sonic Prime and Zonic to stop the threat of Giant Borg. After defeating Giant Borg, Manic and Sonia freed Evil Sonic 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)
Manic is a pickpocket, placing him in the lowest role of growing up for the siblings: Sonic lived in an average home, while Sonia lived like a princess. When their mother was forced to separate them, his basket was stolen and brought to the thief Ferrel, who raised Manic to be a thief. Though Sonia has a distaste for Manic's lifestyle (and his tolerance for sewers), his thieving skills and mastery with computers and machines is greatly needed. Manic seems to be the only one of the three that can pick locks, get away with stealing, fix auto machinery, and hack into computers. While he gets defensive when his old background is criticized, he grew up without ever feeling he had a real home until he met his siblings. Manic is the "laid back" sibling, and speaks slang sometimes in the show. He has a sort of "valley boy" accent.
Manic possesses neither his brother's speed nor his sister's strength, thus making him the only member of the Sonic Underground with no superpowers on his own. However, when used properly, his drum set can control the earth, creating seismic activity under Manic's direction, and fire lasers like those of his siblings. His cymbals can even reflect laser fire. According to the Oracle, his drums are the most powerful weapon of the three. He also rides on a hoverboard (possibly his zone's version of Extreme Gear), which doubles as a surfboard.
- When Sonic mentioned Tails, Manic reacted negatively towards his name, remarking "and Tails?! What kinda name is that?"
- A character closely resembling Manic can be seen in Archie Issue #134 during the scene when Sonic and Sally break up, sitting behind Rotor Walrus.
- Scourge resembles Manic in many way's. The only physical differences being that Manic has spiky and shaggy hair, while Scourge does not. Also, Scourge's teeth are shown as being sharp, while Manic is shown having normal flat teeth.
- Though no other versions of Manic have appeared in the comic, he does have a number of namesakes from possible future realities. Though spelled differently, Sonic and Sally Acorn's counterparts in these worlds had a Hedgehog son named Manik Acorn.
Manic's spikes are shaggier than Sonic's and Sonia's, and he is green while Sonic is blue and Sonia is pink. He wears a red vest, black spiked wristbands, and an orange fanny-pack, which he seems to fit anything and everything in, from his drumsticks, to his lock picks, to whatever he steals. He has brown eyes, and his left ear is pierced with two small gold loop earrings.
