Sonic the Hedgehog is the main protagonist in the television series Sonic Underground. He is the crown prince of Mobius who must travel and search for his mother Queen Aleena and stop Dr. Robotnik with the help of his two siblings Sonia and Manic whom he has a band with.
Shortly after Sonic, Manic, and Sonia's births, Dr. Robotnik seized power of Mobotropolis and converted it into the polluted and metallic city of Robotropolis. A bounty was placed on the children of the Queen Aleena who then was forced to take them into hiding. Eventually, the Oracle of Delphius appeared before her with a prophecy which foretold that she would have to separate her children in order save their lives. Sending the siblings to three different caretakers, Sonic was taken in by his Uncle. Sonic would learn how to play an electric guitar that, he soon figured out, could also be a weapon. He then went off to form a band after meeting Sonia and Manic. The Oracle of Delphius reappeared to tell the children of their origins. Shortly afterwards, Dr. Robotnik captured Uncle Chuck, as well as Sonia and Manic's guardians and roboticized them. It was then that the three hedgehog children would form an alliance with each other to locate their missing mother.
Sonic is a wise-cracker of epic proportions and often can't resist taking a stab at friend or foe alike. He cares deeply for his siblings, despite not always knowing how to work with them. He has a big heart, always willing to help someone in danger. Sonic can be, justifiably, arrogant about his speed and is very impatient because of this. He often has difficulties working in a team or taking the time to make a plan as it would involve waiting or relying on others slower then he is. However he will admit if he made a mistake, though usually not to his siblings face. He has a dislike of water and a near crippling fear of the ocean as he can't swim (as in the games' universe and Sonic X), but his determination and bravery help him push through his fear if necessary. Above all he loves his brother and sister and can be very protective of them. Like in the previous cartoons and the later video game titles, his love of chili dogs remains, and sometimes when eating he shows very poor etiquette, much to Sonia's disgust.
Additionally, as the leader of the team, Sonic tries his best to keep his siblings in line, and often gives orders on most missions. He thus proves himself to be a very strong and capable leader in this regard. When Luke Periwinkle attempted to drive a wedge between Sonic and his siblings, he told Sonic that he decided that he [Sonic] is a better leader and is to be crowned King of Mobius. Before then, Sonic even said himself that when he is coronated, he will assign positions on his court to his siblings.
