A mutant with a computer-like mind, Sage can store massive amounts of data and possesses vast processing power. She has a long history of using her gifts as an undercover operative for both the X-Men and Excalibur, and helps the Exiles protect and restore realities across the Omniverse. She remains a dedicated protector of mutant and humankind.
Spymaster
The woman that becomes known as Sage spends her youth in the Balkans, but as a teenager she lives in Afghanistan when war breaks out. Scavenging weapons and equipment from fallen combatants, and forced to learn to fight both soldiers and local bandits, she discovers the first of her mutant powers—an absolutely precise photographic and kinetic memory. One day, she feels compelled to enter a cave in the nearby Hindu Kush mountain range, where she finds mutant telepath Charles Xavier, AKA Professor X, his legs crushed under a massive stone block after a battle with the alien, Lucifer. She rescues him, but on the trek back to civilization, the pair encounter a Shaw Industries-sponsored United Nations aid convoy under attack by bandits. She shoots most of the attackers and, enraged by the murder of one young UN worker, kills another bandit with her knife. The blood on her hands sickens her, but she simultaneously saves the life of another powerful mutant: wealthy industrialist Sebastian Shaw. She parts ways with Shaw and Xavier once she sees them to safety, returning to her mercenary life; where at some point she is sold to, and subsequently escapes from, a harem.
Xavier soon contacts her, recruiting her to his cause of human/mutant coexistence at roughly the same time he founded the X-Men. While he trains the X-Men to be heroes, he trains her as a spy and double agent, keeping her presence at the mansion a secret; he helps her hone her mental powers, including telepathy and an analytical, computer-like mind, to hide her true intentions from other telepaths.
Living Computer
Sage is a mutant possessing a computer-like, “cyberpathic” mind with unlimited storage capacity and vast processing power. Her photographic and kinetic memory allow her to recall information with incredible speed and accuracy via mnemonic triggers. Like a computer, Sage is capable of parallel processing, performing multiple tasks at once by partitioning her mind to dedicate a portion to each undertaking. Sage could instantly calculate complex statistics, track event probabilities, and analyze behavior patterns.
When merged with the Panoptichron, Sage becomes a living computer. Housed in a massive “crystal palace” that exists outside of space-time, Sage can monitor and scan every reality in the Omniverse. Combining the Panoptichron’s systems with her own computer-like mind, Sage can record and analyze massive amounts of data at blinding speeds. Through the Panoptichron, Sage has access to so much data that she approaches omniscience. She can project a holographic human form that resembles her original body anywhere in the Palace; when the Exiles are in other dimensions, she can monitor and communicate with them through a device called a Tallus, or project a holographic form through the Tallus as well. The Panoptichron contains pan-dimensional transport equipment, medical bays and stasis facilities, synthesizers that can create food, clothing, furniture, etc. (all of which Sage can operate), and several tesseract-like “rooms” that contain various environments, including—now that Sage has given the Palace a soul—living flora and fauna.
Sage has complete conscious control over her own body. She’s a formidable hand-to-hand combatant, able to anticipate opponents’ moves and master any fighting style that she studied. Sage can learn new skills in seconds by downloading and analyzing all data on a skill set, knows several martial arts, and can wield a wide range of firearms with considerable accuracy. Presumably, she is similarly skilled when inhabiting her holographic body.
Sage has an acupressure point on the back of her neck, which can be used to “reboot” her mind in the event of catastrophic failure. Sage has very pale skin, and possesses facial tattoos, which she occasionally hides telepathically, as well as a tribal tattoo around her left arm. She is fluent in more than 123 languages.
Sage’s low-level telepathy allows her to read and manipulate minds, communicate with others over a distance, project her astral form and create realistic mental illusions. Possessed of an ironclad, nearly indomitable will, Sage can reflect most psionic or cybernetic mental attacks back on their originators. She can also purge her body of certain viruses or contagions by force of will. Additionally, Sage has the mutant ability to sense others’ mutant genes. She can also read and analyze people’s genetic codes, and selectively manipulate their DNA to enhance preexisting or latent powers, or heal them from certain injuries. Sage can also channel others’ powers and energies through herself to an extent. It is unknown if Sage retains these abilities as part of the Panoptichron.
As “Diana Fox,” Sage wields a sword, and wears a Shadow Captain uniform provided by Albion that grants her flight, increased strength (lifting in excess of 50 tons) and protection from psionic attacks. The uniform also reshapes and tones her body, and may transfer some powers to her, including body-altering abilities—when Sage and Diana struggle for dominance, Sage flies, demonstrates super-strength and briefly morphs into Diana. At any rate, she can presumably replicate these same feats via her holographic form.
Sage wears a pair of custom “cyber shades” that function as a miniaturized computer, with a wireless broadband connection to her larger network. Built by Kitty Pryde and herself, Sage gives pairs to her X-Treme X-Men teammates, allowing them to communicate via an audio/video feed using miniaturized microphones and cameras. The shades also project holographic images into the wearer’s visual field, which can be expanded outward to allow others to see with whom the wearer is communicating or information they are reviewing. The shades’ sensors can detect energy trails and telepathic resonance patterns, analyze electronic circuitry, and see via thermal imaging. The shades can also interface with external networks, and project a holographic, iconographic keyboard that can also be keyed to a visual input system.
Sage’s custom network, “Sage-Net,” allows her to monitor worldwide events, and can clandestinely tap into several other networks, such as United States surveillance satellite feeds and the Fantastic Four’s and Avengers’ computer systems. It could project a hologram of Sage anywhere on the X-Men’s mansion grounds. Sage gives the network to Lucas Bishop, AKA Bishop, when she leaves the team, and presumably it’s destroyed along with the rest of the X-Mansion—but Sage sets up a second, similar network in Excalibur’s London headquarters.
Sage also carries a knife, wields handguns that fire non-lethal projectiles, and occasionally rides a customized motorcycle.
Opposing Forces
Elias Bogan is often Sage’s enemy, who swears revenge upon her after losing a bet to her while she’s infiltrating the Hellfire Club as Tessa. When he takes his revenge, he brands Sage with facial tattoos. Though she defeats him, it shuts her telepathy down.
While on the Super Hero team Excalibur, Sage goes undercover and joins Albion’s Shadow Corps under the alias Diana Fox. Though an energy discharge affects Sage’s mind, allowing “Fox” to take over and she becomes Albion’s loyal agent known as Britannia. Fox slays some of Excalibur’s Shadow-X allies, but Sage eventually regains her mind and defeats Albion.
When the Omniversal Guardian Merlyn tries to overthrow his daughter Roma, Roma saves herself by transferring her mind and violent aspects of Merlyn’s as well to Sage’s mind. She fights off the personas, who try to claim her body, with the help of Diana Fox who resurfaces and then sacrifices herself to save Sage.
Mutant Allies
As an undercover X-Man most of the time, Sage does not get many opportunities to bond with her mutant allies. However, she becomes close co-workers and friends with Bishop while on a mission investigating murders on an Alaskan Glacier. She also is pivotal in helping her Exiles teammate Talia Wagner, AKA Nocturne, recover from a stroke.
