History Characters / SonicUnderground

* CharacterDevelopment: Initially Sonia was spoiled and prone to complaining whenever her appearance was tarnished. Later in the series, she becomes more of a leader figure, and is easily the most focused of the siblings.

* CompositeCharacter: Previous versions of Dr. Robotnik in Western media offered two radically different portrayals of the character: a humorous, [[LargeHam hammy]], and incompetent villain in ''WesternAnimation/AdventuresOfSonicTheHedgehog''; and a cold-blooded, ruthless, [[KnightOfCerebus dead-serious]] tyrant in ''WesternAnimation/SonicTheHedgehogSatAM''. This Robotnik seems to be an attempt to reconcile these two characterizations: His design is lifted straight from ''[=SatAM=]'', and he's depicted as a powerful, evil ruler; but at the same time is often prone to {{Slapstick}} and the occasional humorous comment that would not be out of place in ''[=AoStH=]''. He also once again has a BumblingHenchmenDuo by his side much like in ''[=AoStH=]'', something the ''[=SatAM=]'' version lacked.

* YouGottaHaveBlueHair: As a match for his punk style.

* YouGottaHaveBlueHair: Navy blue, in this case.

An aristocratic mink and Sonia's ex-fiance. Bartleby is very haughty and is often cowed into paying Robotnik tribute, but helps the hedgehogs on occasion.

* TopHeavyGuy: His upper half is twice as wide as his lower half.

A reptilian mage, the Oracle mentors the triplets, though not always in a straightforward manner. He learned of the ancient prophecy and warned both Aleena and Robotnik about it, setting the events of the series in motion.

* HumanoidFemaleAnimal: Like [[VideoGame/SonicAdventure2 Rouge the Bat]] after her, Sonia lacks the RubberHoseLimbs like Sonic, Manic, or Knuckles but instead has a more humanoid figure.

* WalkingShirtlessScene: Most of the time, he goes without a shirt, in keeping with his

* MsFanservice: Downplayed. Sonia has much more shapely figure than both her pudgy brothers ''and'' other Sonic girls from other continuities, like [[VideoGame/SonicCD Amy Rose]] or [[WesternAnimation/SonicTheHedgehogSatAM Sally Acorn]]. Sonia was the shapeliest female character in Sonic's retinue until [[VideoGame/SonicAdventure2 Rouge the Bat]] debuted. There are also two episodes where she wears a bikini and a very brief scene in The Jewel of the Crown where she dances in a skimpy belly dancer outfit.

* BadassBiker: Rides a pink-and-purple motorbike, and is quite skilled at driving it. It gets destroyed in one episode after crashing into a wall.

* DudeMagnet: Sonia has had a few admirers over the course of the series such as Dingo, Knuckles, Cyrus and Bartleby.

* PintSizedPowerhouse: Slightly shorter than her siblings but has SuperStrength, able to lift and throw Dingo, who is at least twice her size.

* NonStandardCharacterDesign: While Sonic and Manic have round torsos and RubberHoseLimbs, Sonia has a more realistic design, with a slim, curvy body and slightly muscular arms and legs.

Sonia was the shapeliest female character in Sonic's retinue until [[VideoGame/SonicAdventure2 Rouge the Bat]] debuted.

* BadassMustache: It wouldn't be Robotnik if he didn't have it.
