Sonia the Hedgehog

Sonia the Hedgehog is a character that appears in the Sonic Underground television series. She is an anthropomorphic hedgehog, the middle triplet sister of Sonic and Manic the Hedgehog, and the only daughter of Queen Aleena. She is also a member of the Sonic Underground and one of the current leaders of the Freedom Fighters along with Sonic and Manic. She can't speak any English. According to various documents released by Phil Harnage, a screenwriter at DIC entertainment, Sonia was initially conceptualized as the sole sibling of Sonic, rather than being part of a triplet. She would have been the main character of the series, due to the desire by DIC to draw in a female audience. With Sonic himself having little presence in the premise due to having gone off planet to fight Robotnik in other parts of the galaxy. Instead, Sonia would defend Mobius with the aid of her chivalrous porcupine sidekick, Quilley, who would have been able to use his quills as weapons by firing them off at his enemies. He was planned to have a crush on Sonia. Together, Sonia and Quilley would have fought against Grotty, Robotnik's thinner, evil twin who was left in charge after Robotnik and Sonic left the planet. Grotty would have deployed Scratch and Grounder as his primary henchman to fight against Sonia and Quilley.[2]

Sonia was also initially swapped between being Sonic's younger sister, and later on the oldest of the three triplets. She was also meant to have a more "Jessica Rabbit" inspired characterization.[3] Sonia is an anthropomorphic hedgehog with a slim, curvy figure, bright fuchsia fur, pink hair in a style of straight spikes and full fringes, peach skin, and black eyes like her siblings.

For attire, Sonia wears a dark red, sleeveless top, a dark purple miniskirt, and a gold belt that forms a pointed shape at the front and bottom with a round, blue gem in the center of the belt. Unlike most Sonic characters who wear white cartoon-style gloves, Sonia wears long, purple ones that go halfway past her elbows. Sonia also wears red pants under her skirt with dark purple spots on the knees and a thin, purple stripes on each of her thighs, a pair of dark purple boots with red toes, and her royal medallion around her neck. In Flying Fortress, when visiting a beach, Sonia wears green sunglasses and a blue bikini with yellow stripes. In The Big Melt, she goes to the beach again and instead wears a yellow, midriff-baring t-shirt with a white stripe across the chest and a yellow bikini bottom. Sonia also has two known winter outfits, identical in appearance but with differing colors. Sonia is one of the heirs to the throne of Mobius, who are prophesied to rule as the Council of Four. In order to fulfill this prophecy, Sonia was separated from her family shortly after birth. She was raised by the wealthy Lady Windermere until her unfortunate roboticization by Dr. Robotnik. Following the "song in her heart," she reunited her brothers Sonic and Manic. After a period of training, she and her brothers set out to find their lost mother, defeat Dr. Robotnik, and restore order to Mobius. Shortly after the royal triplets' births, 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 Queen Aleena 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 with her children in order save their lives. She sent the siblings to three different caretakers, and Sonia was placed in the care of Lady Windermere, an aristocrat. Sonia would learn how to play the keyboard and went off to form a band after meeting Sonic and Manic. The Oracle of Delphius reappeared to tell the children of their origins. Shortly afterwards, Dr. Robotnik captured Lady Windermere, as well as Sonic 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.[4] Sonia and her siblings would engage Robotnik in battle many times. Evil Sonic would appear in Manic's reality on a mission from Robo-Robotnik v1.0 to recover the Giant Borg. Believing 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: Sonic Prime and Zonic the Zone Cop. Sonia, Sonic and Manic mistook Sonic Prime for Evil Sonic until the two new hedgehogs explained who they are. Zonic would remark how he had a lack of data on Sonic and his dimension and would request an explanation of their reality's history.[4]

Sonia, Manic and Sonic would then team up with Sonic Prime and Zonic to stop the threat of Giant Borg. After defeating Giant Borg, Sonia and Manic 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 Sonia and her siblings to continue their fight.[4]

Around the time of Sonic Prime's absence following the Xorda Attack on Mobius, Sonia and her siblings made a visit to Mobius Prime as part of an Interdimensional concert tour.[5] As Sonia was raised with luxury and wealth, she was originally quite high-maintenance, spoiled and snotty. She hates getting dirty and constantly worries about the condition of her hair and clothes. Although she appears to be selfish, she is generally good-natured and helps those that; are in need. Sonia is known to occasionally talk like a valley girl. Sonia always addresses her mother as simply "Mother" due to being raised in a polite society.

Despite all this, Sonia has been shown to like performing daring acts, such as walking on a high brick wall. She is also very athletic, and appears to be good at gymnastics. Sonia is very self-sufficient and does not hesitate in taking on any threat or challenge that she may encounter, often coming out on top. She likes to think things through and on many occasions, has helped her brothers out of their own troubles (although she sometimes thinks of them as nothing more than pains). Sonia hates messy things like dirt and mud. Sonia is physically the strongest of her siblings. She is able to lift heavy objects[6] as well as destroy barriers of various materials. She is skilled in martial arts, which she uses for offensive and defensive measures, and is also extremely agile. As a child, she was shown to be able to balance from high beams, and gracefully flip down on her feet. As an adult, she can easily flip and dodge around Swatbot beams. She does not have Sonic's speed, but is able to use the Sonia Spin, where she spins in a cyclonic manner. She also has a photographic memory.

Sonia holds excellent piloting skill and talented driver, for example she rides a motorbike like a real pro who can perform stunts, in the episode "Come Out Wherever You Are" Sonia pilots the predator with virtual passengers with a lot of address then in real with the same results. In addition, she is remarkably good at belly dancing, which she performed disguised as a dancer on "the cosmic dance" in order to go unnoticed. Like her brothers, she has mastered the art of disguise skillfully enough to sneak around and etc.

Sonia is a very talented singer and keyboard player and has been a great pianist since childhood, as shown in the episode "Beginnings". In the song "Liberty's Gonna Rock", Sonia is shown to be able to play the piccolo as well. Sonia's medallion transforms into a keyboard synthesizer which is capable of firing laser blasts as well as creating smoke screens. The keyboard also transforms into a laser rifle which she uses to attack.
