Sage is a mutant who possesses a cyberpathic mind that functions like a computer with unlimited storage capacity. Sage is able to record and analyze vast amounts of data, including the entire genetic code of another living being, and can also calculate complex statistics in mere seconds.
Sage’s memory is kinetic in nature, allowing her to instantly recall specific information with incredible speed and accuracy. Sage also possesses the ability of total recall, as her mind stores everything that she sees and experiences. As such, Sage is able to track the probability of an event by piecing together stored data.
Like a computer, Sage is able to perform multiple tasks at once by allocating a partition of her brain to each task. For example, Sage can use her mind to replay a movie she had watched previously, play a game of Internet chess, and focus on battling an opponent without any one task distracting her from another.
After analyzing the DNA of another superhuman mutant, Sage is able to selectively evolve their existing genetic traits as well as catalyze the untapped genetic potential of latent mutants. Once begun, the procedure is irreversible and can often result in unpredictable side effects.
Sage can also sense the presence of the mutant gene in others who are in close proximity to herself, and can reflect mental attacks - be they psionic or cybernetic in origin - back on their originators.
Sage also once possessed low-level telepathic abilities that allowed her to read minds, communicate with others over a distance, project her astral form, manipulate the minds of others, and create realistic mental illusions.
Little is known of the life of the woman known as Tessa except that she had lived in a small village in the Balkan region of Europe whilst still a young girl, and that she had spent time in a harem under unrevealed circumstances. Just prior to her teenage years, Tessa found herself caught up in the Russian invasion of Afghanistan. She was forced to learn to fight to survive encounters with both soldiers and local bandits, and took weapons and equipment from the bodies of fallen combatants. One day, Tessa felt herself compelled to enter a cave in the nearby Hindu Kush mountain range. There, she found the powerful telepathic mutant named Charles Xavier, who had been trapped under a massive stone block by the alien being named Lucifer. Initially wary of him, Tessa rescued the critically injured mutant but soon after they encountered a United Nations aid convoy being attacked by bandits. Tessa drove off the attackers and then avenged the death of one young U.N. worker by brutally murdering the bandit that had raped and killed her.
Years later, Xavier recruited Tessa at the same time that he formed his original team of teenage mutant students he called the X-Men. Xavier kept Tessa's presence at his mansion a secret as he intended to utilize her own mutant telepathic talents as a spy in his fight for peaceful coexistence between mutants and humans. Tessa's first mission was to infiltrate the organization for the rich and powerful known as the Hellfire Club and to gain the trust of Sebastian Shaw, leader of the Club's Inner Circle at its New York branch. For years, Tessa acted as Shaw's familiar, advising and counselling him in both his legitimate and illegal business practices, all the while gathering information for Xavier. Shaw found Tessa's ability to function as a living computer invaluable and kept her in his employ for many years, even during the time he was deposed as leader of the Club.
Early in Tessa’s time with the Club, its renegade White Bishop, Donald Pierce, attempted a coup of the Club's leadership. Pierce kidnapped Tessa, believing that without her Shaw's position could more easily be compromised. She was rescued by Xavier and his team of New Mutants and, upon her return to the Club, Pierce was expelled.
Later, Tessa ran afoul of one of the Club’s regular and valued patrons, a reclusive billionaire named Elias Bogan. Shaw had made a wager with Bogan during a game of cards whereupon if Shaw lost, Bogan would win the Club's then-White Queen, the telepathic mutant Emma Frost. Bogan had never lost a game before, but with Tessa’s help Shaw won the bet. Bogan honoured the wager, but knew who was truly responsible for his defeat and exacted his revenge on Tessa, capturing her and branding her face with facial tattoos. Rescued by the X-Man Storm, Tessa soon affiliated herself with the X-Men, acting as part of their support crew. In order to shield herself from detection by Bogan, Tessa consciously shut down her telepathic abilities, relying solely on her computer-like mind to assist her new teammates.
When Senator Robert Kelly announced his intention to run for the Presidency on an anti-mutant platform, Tessa met with him to persuade him otherwise by convincing him that his actions were no different to those of the mutant terrorist Magneto. Kelly was not so easily swayed, however, and it wasn’t until a mutant sacrificed his life to save Kelly that he realized his folly.
Soon after, Tessa was given the codename Sage by Storm who recruited her into a splinter group of X-Treme X-Men who set out to search for the diaries of the blind mutant seer named Destiny that predicted the future of mutantkind. On the new team's first mission, Tessa was instrumental in saving the life of her teammate the Beast after an encounter with the self-professed enhanced human named Vargas. Sage used a heretofore-unseen ability to advance the Beast's evolution to its next stage, healing him of his injuries and activating his latent secondary mutation.
Eventually learning of Tessa's deception, Shaw allied himself with Lady Mastermind, the daughter of former Hellfire Club member Jason Wyngarde, to exact revenge on his former assistant. Lady Mastermind trapped Tessa in a convincing illusion, making her believe that she was once again Shaw's assistant back in the Hellfire Club. Tessa was freed thanks to the efforts of Heather Cameron, an Australian mutant with the ability to manifest various super-human powers depending on what the current situation called for, and the X-Men defeated Shaw once more.
Tessa later catalyzed the latent mutant powers of Heather’s brother Davis, who subsequently joined the X-Treme X-Men as Slipstream, as well as evolving her teammate Rogue's mutant ability to grant her control over the manifestation of the powers and abilities she has absorbed over the years.
Tessa often used her computer-like mind to assist her teammate Bishop in his activities as a homicide detective, such as when they were called upon to investigate the attempted murder of Emma Frost, now a member of the X-Men and an instructor at Xavier’s school. Later, when the X-Treme team encountered Bogan once more after a murder at his Alaskan estate, Sage and Bishop were called in to investigate. A young mutant named Jeffrey Garrett was wanted for questioning after Bogan had his family killed and, in retaliation, he teleported Bogan's associates onto the nearby glacier where they froze to death. Garrett fled to the Xavier Institute where he came under the protection of Frost. However, Bogan had secretly possessed the young boy and when Frost scanned his mind, Bogan took possession of her. Sage and Bishop followed the trail to the mansion where Bogan captured them, but the timely arrival of Storm allowed them to escape and defeat the villain.
Bogan returned to plague the X-Treme X-Men soon after when he captured and mentally enslaved Bishop, hoping to use him as a weapon against his teammates. With the aid of several of their former allies the X-Men were able to rescue Bishop, which allowed Sage to defeat Bogan once and for all. Sage then accompanied her teammates back to New York to assist in the rebuilding of the mansion following an attack by Magneto, after which they rejoined the core X-Men team.
After a period with the British superteam Excalibur, Sage became a member of the interdimensional group, the Exiles.
