Tessa
History
Tessa lived in a harem in the Balkan region of Europe. In her teenage years, the Russians invaded Afghanistan so she had to learn how to use weapons and fight against soldiers and local bandits. One day, she felt compelled to enter a local cave and found Professor Charles Xavier trapped under some rocks, his legs crushed. Soon after, some bandits who had raped and killed a convoy of U.N. workers attacked them, but Tessa drove them off, killing one of them.
Some time later, Professor X recruited her into the X-Men, but kept her secret so she could use her telepathic power to spy for his fight for peaceful co-existence between mutants and humans. Tessa’s first mission was to infiltrate the Hellfire Club and become Sebastian Shaw’s advisor. Shaw even kept her after his leadership, due to her usefulness of keeping large amounts of information.
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.
X-Treme X-Men costume
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.
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.
Sage in New Excalibur
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.
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.
She then left the Hellfire Club to join Excalibur, the mutant team based on Britain. Tessa becomes a spy again in order to get close to Albion, and she develop a new personality, calling herself Diana Fox, who is completely loyal to Albion. She quickly climbed up through the ranks and eventually become one of Albion's elite, the Shadow Captains, and took the name, Britannia. When she had an opportunity to kill Albion, she didn't take it, and much to the fear of Tessa's Excalibur teammates, her Diana Fox personality now fully control Tessa's body. But when she was confronted by her teammates, Tessa's came back to her old self and quickly defeated Albion and his Shadow Captains.
Excalibur came back to their base and celebrated their recent victory, Sage felt that guilty about her actions. The party was crashed surprisingly by Psylocke and an alternative version of Thunderbird, who are both members of the reality fixing team, Exiles. Then the party was abruptly ended when the Rouge-Mort attack Excalibur. The battle escalated to the point that it will destroy the Multiverse by a psychotic Merlyn with the help of the Fury. When Merlyn stabbed Roma and is now slowly dying, she transfered all her knowledge about the Multiverse to Sage, which almost driven her mad. Fearful of the knowledge she now possessed might fall in the wrong hands, she joined the Exiles to be safe.
As Britannia
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.
