Shade is a character introduced in Sonic Chronicles: The Dark Brotherhood. She is initially the second most major villain in the game until half-way through the game, in which she switches sides and joins forces with Sonic. She is the second in command for the Dark Brotherhood. She is an Echidna like Knuckles. She is one of the most powerful characters on the team and is also is the last one to join. The Dark Brotherhood take her to be a traitor after she joins Sonic. She then helps Sonic stop the Dark Brotherhood by leading them.
Shade's character and role are loosely based on the that of Julie-Su, a former reoccuring character in the Sonic the Hedgehog comic book series by Archie Comics. Likewise, the Dark Brotherhood she hails from is inspired by the comics Dark Legion.
