Following the aftermath of the Avenger's vs. X-Men, and later their team-up against the Phoenix Force and its subsequent "destruction", new mutants began to appear all across the world. This was largely due in part to the efforts of both Hope Summers and the recently resurfaced Scarlet Witch, with Wanda desiring to undo the damage she had caused by triggering the mass depowering of a majority of Earth's mutant population, known as both "M-Day" and "Decimation."
With new mutants awakening across the globe, a renewed mutant rights sentiment spread like wildfire, primarily among the youth of America, who identified with them on some level. One such movement was taking place at the University of Texas, where a mass demonstration was being held by the student body to show their support for the mutant community. Benjamin was present for this event, but tried to stay detached from the situation, not wanting to be caught up in the hype caused by recent events, even though one of his friends was persistent that they were making an impact by letting their voices be heard. It was during his conversation with her that his powers first manifested themselves, and he shapeshifted into her form without warning. When he saw what he had become in the reflection of the girl's cell-phone, he had an... "understandable" reaction (i.e., he fainted on the spot).
Needless to say, this caused quite the stir among the other demonstrators, not to mention his peers at the University. They saw his powers as something incredibly cool, and for a while, he was the talk of the campus. Even the local media got involved in covering the emergence of his abilities. However, Benjamin wasn't too keen on all the attention he was getting. He didn't even know if being a part of something as big as the X-Men or the Avengers was something he wanted for himself yet. He didn't even know if he could call himself a mutant because he believed mutants were extinct for the most part, after the events of M-Day.
That night, at a party on campus, his life came crashing down around him when Cyclops and Magneto appeared to try and recruit him for their newly reformed Exctinction team, saying that he was indeed a new mutant, and that the new mutant revolution was beginning. Their attempts were cut short, however, by the arrival of the time-displaced original X-Men, brought to the future by Beast to try and talk some sense into Scott. This wasn't received well by either party, and a battle between them broke out, decimating a large portion of the campus. The fact that such a fuss was being made over him only made Benjamin even more famous, much to his chagrin.
The next day, Benjamin was expelled from the University of Texas, due to his status as a new mutant having brought "the wrong kind of attention" upon the school. His parents refused to answer his calls, and he had nowhere to go. His friend from the rally tried to console him, but he would have none of it, claiming her talk of mutant equality was all good in theory, but that none of them were willing to practice what they preached when a mutant was staring them in the face.
He left to try and figure out what to do now, only to run into Cyclops, who admitted he was responsible for the damage Ben's life had suffered in the wake of his battle with the original X-Men. Angry, Ben wanted to know why Scott had gone after him in the first place, and was told it was because he was a new mutant, and that Scott was trying to create a team to protect people like them, as well as offer them a place where they could grow and come into their powers of their own volition. He offered his services to Ben again, and the young man hesitantly decided to see what the X-Man had to give him. The two were then teleported to the site of what was once Weapon-X, but now the new Charles Xavier Institute for Gifted Youngsters, the headquarters of the Extinction X-Men, and the new mutant revolution.
Benjamin Deeds was created by Writer Brian Michael Bendis and artist Chris BachaloStuart Immonen. He first appeared in the story "The New Revolution" in Uncanny All-New X-Men #1 #4 (AprFeb. 2013).
Powers and Abilities.
Benjamin mutation grants him a unique form of shapeshifting, although he is not essentially becoming another person. This is evidenced during the rally when his powers first activated and he mimicked the form of his friend from the rally. He gained aspects of her appearance (physically changing gender/sex, gaining her red hair, freckles, and green eyes), but retained his height and lean physical build, whereas she was shorter, and had a stockier physique. His ability is better described as a form of "environmental adaptation," physically adapting to his surroundings by mimicking another's appearance, almost like a chameleon changing colors, but not becoming a part of the tree or taking on its properties. While his powers are still in their infancy, it appears he needs to have an intended target within his immediate line of sight to mimic their form, though this may change with time and training. His powers also do not seem to allow him to mimic the powers or abilities of the people who's form he assumes, as seen when he mimicked Cyclops' appearance, but did not gain his optic blast ability.
