Moira MacTaggert

Origin

The daughter of Lord Kinross, Moira Mactaggert was born in Scotland. Moira met and fell in love with Charles Xavier (Professor X) at Oxford University, as a graduate student. However she was forced by her father to marry a politician named Joseph MacTaggert and broke up with Xavier. Joseph was an abusive husband, beating her and then finally raping her. There after they had a son named Kevin, who was a mutant menace with the ability to alter reality at will, but she had kept her pregnancy a secret and when Joseph refused to divorce her, she made people believe she was widowed. Moira operated a high-tech Mutant Research Center on Muir Island and it was the largest most advanced facility of its kind that was owned and operated by a private individual. At one time she used the facility to do genetic research and confine her son Kevin (and mutants she and Prof. X considered to dangerous), who was later named Proteus when his powers had become uncontrollable. There she continued to research the human/mutant genetics who hoped to find a cure her son. Moira also adopted an orphan mutant named Rahne Sinclair, also known as Wolfsbane.

X-Men

MacTaggert was a partner in founding Xavier Institute for Higher Learning and was the co-creator of Cerebro and had met the X-Men when Xavier called her to become the mansion's housekeeper. There, she met Sean Cassidy (Banshee), and formed a on-off relationship with him, for the rest of her life. Proteus had escaped and was killed by Colossus. Banshee stopped her from cloning him but saved his DNA so she could clone him in the future. MacTaggert also did not like the thought of Xavier opening up a new school to the new generation of mutants called the New Mutants with MacTaggert's foster child, Rahne joining the new school.

With the apparent death of the X-Men, MacTaggert and Banshee formed their own team when the X-Men were away. MacTaggert however, was not her usual self, exerting herself as selfish, short-tempered and she made harsh decisions. She even made the new alternative X-Men team battle against each other mercilessly to study mutants in action. It was then revealed that Muir Island was being possesed by the Shadow King but Xavier had freed them from King's mental control.

When Magneto discovered that MacTaggert had tampered with his free will, he took her hostage and forced her to do this to half the X-Men. However, it was revealed that the X-Factor which brought out the mutant abilities in the X-Men reversed the effects of the experiment which meant that Magneto had been doing things on his own free will. On Astroid M, MacTaggert was held hostage and witnessed Fabian Cortez being manipulative towards Magneto and draining his life force.

Legacy Virus

Moira volunteered to work as a geneticist on Genosha about an unknown virus when she returned to Earth and discovered Magik with the same disease to discover later identify it as the Legacy Virus. She returned to Muir Island after Magik died hoping to find a cure for this. Excalibur then lived with MacTaggert on Muir Island where she became an official member of the group as a medic and all round warming team member. She later revealed she was infected with the Legacy Virus. It is unknown how she contracted disease, but possible reasons are her prolonged exposure to the virus on Genosha, giving birth to a mutant or during the autopsy of Magik. However, she continued to live her life still providing her role in Excablibur. She locked herself in a quarantine attempting to cure herself yet it was foiled by Wolfsbane and Douglock, as Wolfsbane wanted to carry on her mother's work yet Douglock had caused a lot of unintentional damage because of his personal feelings towards Wolfsbane.

Moira did a find a cure, but Mystique had the virus to target only humans. Then, with Sabretooth, they destroyed Muir Island. Bishop, Wolverine and Rogue tried to save MacTaggert's life. Using her absorbing powers, Rogue had temporary medical knowledge, but even that could not save MacTaggert. However, she was able to use her powers to let MacTaggert and Xavier speak with each other for the last time and finally, MacTaggert died. As a ghost, she has directed Banshee to a hidden room full of videos and has been apart of Xavier's mind.
