Sonia the Hedgehog

Sonia the Hedgehog is a fictional character created for the animated television series, Sonic Underground, which takes place in an alternate universe. She is an eggplant-colored anthropomorphic hedgehog with orchid spikes and hair of the same color. She bears a close resemblance to the Sonic CD design of Amy Rose. In this universe, she is the sister of Sonic the Hedgehog and Manic the Hedgehog, as well as the daughter of Queen Aleena Hedgehog. Unlike her brothers, she does not have tan colored arms and stomach/chest.

In regard to wardrobe, Sonia wears a dress with a short dark blue skirt and a red sleevless top. The two sections are separated by a band of gold that forms a pointed shape at the front with a small circle in the center of it. Unlike most Sonic characters who wear gloves, hers are blue and go up to the elbows rather than the stereotypical white hand gloves. Sonia also wears red stockings under dark blue boots, the toes of which are a matching red.

Sonia is voiced by Jaleel White (who also voiced Sonic and Manic in the series), and her singing voice is provided by Louise Vallance.

She is the second oldest of the triplets.

History
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 Windemere until she was 15, when Windemere was roboticized by Dr. Robotnik.  Following the "song in her heart", she found 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.

Personality
As she was raised with luxury and wealth, Sonia tends to be quite high maintenance, spoiled, and snooty. 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, despite being voiced by a male in the English variation of the show.

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 (altough she sometimes thinks of them as nothing more than pains).

Abilities
Sonia is physically the strongest of her siblings. She is able to lift heavy objects 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. She does not have Sonic's speed, but is able to use the "Sonia Spin", where she spins around a vertical (rather than horizontal) axis (similar to Taz of Looney Tunes, or the attacks eventually used by Blaze the Cat). In addition to the Sonia Spin, Sonia uses a pink motorcycle to travel. She also has a photographic memory.

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.

ESP
The members of the Sonic Underground seem to have ESP or some other kind mental link. Most examples of this are them being able to play the same song in perfect harmony without rehearsing, and sometimes when they're miles away from each other. Also, when Sonia points out that she has a photographic memory, her, Sonic, and Manic all get the same idea at the same time, and the brothers smile and say "CHEESE!"

As a Musician
Sonia and her brothers are the members of the band "Sonic Underground", who perform various songs as they travel. She plays the keyboard as she has been a great pianist since childhood, as shown in the episode "Beginnings". Her keyboard occasionally sounds like an organ. In the song "Liberty Rocks", Sonia is shown to be able to play the piccolo as well. Her singing voice is so remarkably different from her regular voice that it sounds country-like, as opposed to Sonia's normal high pitched, "girlfriend" voice, however, in Fun in the Sun, she can sing very low.

Love life
Sonia is the only hedgehog in the series (Sonic Underground) with any sort of love life. She is shown to be often infatuated with various suitors, but knows the time and place for i When an orange tiger named Stripes greeted Sonia, he fell in love with her. However, he was working for Dr. Robotnik, who was trying to pin the location of the Sonic Underground. Stripes gave away the locations of Sonic and Manic, but did not mention Sonia because he did not want Robotnik to harm her. She also has a crush on Knuckles the Echidna. She is also the object of a crush from Robotnik's muscle henchman, Dingo. In one episode, Knuckles seems to portray a little affection for her while considering a deal with Robotnik.

Sonic the Hedgehog (comics)
In the Sonic the Hedgehog comic series, Sonia makes an appearance in Sonic Super Special #10, which is titled "Crossover Chaos". In this series, she and her brothers are part of one of many alternate universes. This separates the Underground series from the canon of the comics, most likely caused by the fact that Sonic already had parents in the comic's canon. The issue had the Sonic underground team up with the Sonic Prime in order to stop Robotnik, who had used Evil Sonic to rebuild his Giant Borg suit. Due to being in an alternate universe, it is unlikely that Sonia will reappear in the comics.

Sonia, the daughter of Sonic and Sally Acorn, was named by the writers after Sonic Underground Sonia, the only other acknowledgement the comics have made of the series. Thought this Sonia looks nothing like the Sonia of Sonic Underground, more resembling a young version of Princess Sally Acorn.
