Sage

History

Hellfire Club

Later, Shaw made a poker bet with billionaire Elias Bogan where if Shaw lost, he would have to hand over Emma Frost, though if Bogan lost Shaw would receive his entire fortune. Bogan had never lost a game before, but astonishingly, Shaw won, mainly due to Tessa's help. Bogan knew that Tessa was the one responsible for Shaw’s win and captured Tessa, scarring her beneath the eyes. Abandoned by Shaw, Tessa was saved by Storm, and she joined the X-Men, though she nullified her telepathic abilities to prevent Bogan from finding her again.

When Senator Robert Kelly ran for president, Tessa met with him to persuade him that his actions were no better than those of the mutant terrorists. However, Kelly was not convinced until a mutant saved his life where he realized that some mutants use their power for good.

X-Treme X-Men

 

Tessa was then given the codename Sage by Storm, who recruited her into the X-Treme X-Men who had been set out to search for a mutant named Destiny who could predict the future. On their way, Beast was almost killed by Vargas but Sage used her previously unseen ability to advance his evolution to the next stage.
 
Shaw found out that Sage was a spy for Professor X and he allied himself with Lady Mastermind, the daughter of Mastermind to plan his revenge. Lady Mastermind created an illusion against Sage, making her believe that she was an assistant for Shaw once more. Sage was freed once again thanks to Lifeguard, a mutant with the ability to use any power, depending on the situation. The X-Men defeated Shaw in the end.

Sage later increased Slipstream’s power and allowed Rogue to control the powers she has absorbed over the years. Sage would also help out Bishop in his other missions.

Encountering Elias Bogan

Later when the X-Treme X-Men encountered Elias Bogan again, Sage and Bishop were called to investigate because of a murder. A mutant called Jeffrey Garrett was wanted for questioning when Bogan killed his family and Garrett teleported Bogan’s associates up to the mountains to freeze to death. Garrett fled to the Xavier Institute, where Emma Frost scanned his mind, and she was now possessed. Sage and Bishop followed the trail where Bogan held them hostage, but Storm arrived just in time to defeat the villain.

Bogan captured and possessed Bishop and would use him as a weapon against his teammates. The X-Men with other allies were able to rescue him, which allowed Sage to defeat Bogan once and for all. Sage helped the X-Men rebuild the mansion after Magneto’s attack, and rejoined them.

After concluding that Destiny's writing on the diaries to be invalid, Tessa joined the X-Treme Sanctions Executive, to monitor mutant relations and activities around the world. She had to end her tenure to the group and join again the Hellfire Club to watch over Sunspot, who had become a high ranking official in the Club, because he might become corrupt with power as Shaw did in the past.

Powers

Sage is a mutant with a computer-like brain. She can process large volumes of data with great efficiency, and has a photographic memory that allows her to recall anything she needs. She also has the ability to detect and manipulate the genetics of others. So far this ability has been used to unlock latent mutant abilities in normal humans, and to unlock hidden aspects of mutant powers. This ability works closely with her computer-like mind giving her the ability to quickly analyze and understand the subject's DNA. Sage exhibits strong willpower which protects her from certain telepathic attacks. She also has low level telepathic abilities which allow her to interface with others, which she can shut off at will to lock others out of her mind.

Sage is in peak physical condition and is skilled at both unarmed and armed combat. She is skilled with technology, and uses a set of VR glasses that allow her to interface with computers and other technology. Other people can link up with similar sets of glasses.

Telepathy

Sage is a low-leveled telepathic mutant with the ability to read minds, project her thoughts, control minds, project her astral form and project realistic illusions. She is able to sense any form of life near her and can sense the mutant gene inside of someone. Also she can reflect telepathic attacks away from her by using her 'Firewall' ability. She can only use this by shutting her telepathic powers off.

Sage can also see the genetic structure of a person. She can read the DNA and understand their power (If they are a mutant) probably better than the person can themselves. She can then boost the person's powers advancing them to a certain extent. Also she can see the potential in a human to become a mutant and jumpstart their latent power.

What If Magneto and Professor X formed the X-Men Together?

Sage was among the mutants who were trained by Professor X together with Magneto on his side. Sage's powers became very useful for both men for detecting mutants to join the X-Men. Since her powers were enough to locate mutants, Professor X did not attempted to develop the Cerebro, a machine that can also locate mutant brain waves. But when the Professor finally decided creating the Cerebra for wider range of mutant detection, he asked Sage to test the machine. Following some events, she became the Professor's Executive Assistant.
