Sage (Sonic the Hedgehog)

Sage (セージ Sēji?) is a character that appears in the Sonic the Hedgehog series. She is an artificial intelligence created by Dr. Eggman, which he used in an attempt to harness the technology of the Ancients during the Starfall Islands incident.

Appearance
Sage resembles a human girl. She has a slim body and limbs with white skin and a large, round head with a high forehead. In particular, she has glowing red eyes and a red energy structure on the left side of her face. She also has short white hair with swirls on her forehead with a single red energy highlight within the swirls. However, the rest of her body, especially her arms, and legs, are completely black, with what appears to be red computer code outlines around them. As for her outfit, she wears a black cloak and shoes, covered with red computer cords that outline the inside and most of her right side. However, when Sage becomes sympathetic or emotional, her design flips to a white cloak complete with blue wireframes and her eyes.

Powers and abilities
Utilizing abilities while uploaded in Cyber Space, Sage can act as an observer over the Starfall Islands.

Sage is incredibly smart. Her processing power can compute all known elements in 1,700,050 simulations. What Sage Knows. All of Dr. Eggman's historical knowledge since the beginning of his expedition to the Frontiers[10], previously she had shared acerbic opinions about Sonic the Hedgehog with her creator, and ancient data, consisting of its very essence. This would include all the knowledge the ancients had of the End.

Since it is made from data, Sage's form does not have substance. This form of existence and cyberspace benefited her movements such as levitating, phasing through walls, and casually teleporting within an area. She is mostly shown to levitate and teleport, but she flew out of the Eggmobile to possess the Supreme, so that doesn't mean she can't do a basic flight.

Sage can also operate the machines of the Starfall Islands. Additionally, she has the ability to shoot laser beams from her hands after gathering energy, and has some control while in cyberspace.

Daily Dose of Hydro's Life Lost World: The Movie

 * Sage appears in the movie as a deuteragonist. Her and Hydro Pilgrim met at Starfall Islands that is near to the beach for vacation.
 * She is the third companion along with S.H.I.R.0, and Chip.

Trivia

 * Sage's name is an anagram of "Sega". Ian Flynn, in a cheeky tone, denies that officially the name is a nod to the Sonic Amateur Games Expo, an online annual fangame exhibit meant to highlight community made content.
 * Despite similarities between the characters, Ian Flynn denies taking inspiration of Phage from the Archie series when writing Sage. He states "[both characters] were meant to have a degree of detachment, but Phage was always meant to be spooky and off-putting; there was never meant to be a degree of humanity to her, or what was there was just enough to make her likeable, but even more unsettling. They were different interpretations of the digital character idea".
 * According to Ian Flynn, Sage's development creation was roughly around the same time Evan Stanley pitched Belle the Tinkerer, another robotic "daughter" of Eggman, for the IDW series. This caused Flynn to feel awkward about how to break the news to her, but he took retrospective confidence in knowing that they are two separate personalities despite their similarity.
 * Sage's design is thought to be a homage to Rei Ayanami from Neon Genesis Evangelion in appearance and personality, though this has not been confirmed. Both characters share the same English and Japanese voice actresses (although in Rei's case, Ryan Bartley only voiced the character in the Netflix dub).
