Sage (セージ Sēji) 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. She is the secondary antagonist turned deuteragonist of Sonic Frontiers.
Appearance[]
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 and shoes that are covered with red computer code outlining the insides and the majority of its right side. However, when Sage becomes sympathetic or emotional, her design inverts to a white cloak with blue wireframing and eyes.
Personality[]
Sage, being an AI, strictly abides by the programming set by Dr. Eggman. As a result of this, she runs entirely off of logic, is unable to feel sympathy towards others, and is generally indifferent towards the feelings of others. This also results in her taking extreme measures when a potential threat is nearby, such as summoning powerful guardians to attack Sonic in an attempt to get him to leave the islands, or imprisoning others in an attempt to discount external variables. Despite this, Sage is also generally cautious and reserved, often warning Sonic about the dangers that may come from trying to save his friends.
While Sage initially sees little worth in trying to reason with Sonic or try to explain her antagonism towards him as a result of Eggman not programming her to assist him, and because of accessing the data from Cyber Space being restricted to outsiders, she begins opening up and becomes more sympathetic after getting to know Sonic. After observing Sonic throughout his adventure of the Starfall Islands and seeing how much he means to his friends, Sage began treating him with more empathy and respect, somewhat to the point of idolization. When she begins warming up to Sonic, she also becomes more pacifistic in nature, as she tries to suggest to Eggman repeatedly that they should be allies. She becomes concerned for Sonic when the End winds up trapping him between dimensions. She also becomes considerably more optimistic and hopeful through Sonic's influence, which is in sharp contrast to her calculative and almost fatalistic nature.
