Sage

Sage (セージ) is an artificial intelligence created by Dr. Eggman. 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.

Sage is initially cold and calculating, making decisions solely considering projections and logical analysis. She expresses caution when attempting to preserve anyone's safety to escape any impending threat. As her bond with someone grows, however, she becomes more caring, experiencing familial love, and even telling jokes. By observing the way people interact, Sage develops her own desires beyond her programming, and becomes substantially more cooperative and concerned for the safety of others.
