Sage - Sonic

Sage is a humanoid artificial intelligence program created by Dr. Eggman, whom he used in an attempt to harness the technology of the Ancients during the Starfall Islands incident. She is also known as his best creation and "daughter" along with having full access to Eggnet and his said to be the future heir to the Eggman Empire.

Sage is cold and calculating, initially making decisions solely considering projections and logical analysis. She believes that the results of her calculations are absolute and cannot be defied. She holds disdain for Sonic and friends as reckless and irrational beings, preoccupied with notions like love, and argues that they are out of depth and better off giving up.

Her highest priority is ensuring the safety of Dr. Eggman. As she grows closer to Eggman, she gains interest in having a family, seeing him as her father and his creations as her brothers. She also grows impressed by Sonic's defiance of her predictions, and saddened by the thought that his bravery will only lead to ruin. When The End appears, Sage grows frantic to protect Eggman, and is excited as he agrees to collaborate with Sonic, increasing Eggman's chances of survival. She eventually sacrifices herself to stop The End, showing the love she developed for her creator.

Despite developing a begrudging admiration for Sonic and experiencing love for herself, Sage remains beholden to her logical ways and is a staunch supporter of the Eggman Empire's campaign for world domination. She emphasizes to Sonic that their alliance on the Starfall Islands is only to protect the world so that Dr. Eggman may rule it. She belittles those who defy Eggman and his plans, engaging in understated but brutal trash talk with other racers during Dodon Pa's CrossWorld Grand Prix. She is wholly subservient to her creator and just as devoted to taking over the world as he is.
