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.
