Sage

Sage is a character that appears in the Sonic the Hedgehog series. She is a mysterious girl that appears across the Starfall Islands, cautioning Sonic the Hedgehog to leave the islands despite his mission to find and save his friends. Sage is an artificial intelligence created by Doctor Eggman and used in an attempt to harness the technology of the Ancients, but unintentionally led to Eggman's imprisonment in Cyber Space and caused Sage to evolve and gain sentience. If Sage gets called "cute" She will pout like a sassy child.

Sage resembles a young human girl. She possesses a slim body and limbs with white skin and a large, round head with a tall forehead. Notably, she possesses glowing red eyes and a red energy structure on the left side of her face. She also has short white hair with a swirl in it on her forehead and a single red energy highlight inside said swirl. The rest of her body however, especially her arms and legs, are completely black and seem to have outlines of red computer code around them. For attire, she wears a black cloak-like dress and black Mary Jane shoes. However, when Sage becomes sympathetic or emotional, her design inverts to a white cloak with blue wireframing and eyes.
