Mystique

Mystique was a cold, ruthless and evil woman who would kill without a second thought. This was a result of her being cruelly experimented on. She is very beautiful, seductive and aggressive whenever she disguises herself as someone else. She likes to mess with people's minds or keep her victims company like Senator Kelly and Wolverine while impersonating Henry Gyrich and Jean Grey. Mystique had an extremely low opinion of humans in the original timeline, at least once angrily referring to them as "homo sapiens"; this came from their treatment towards both her personally and mutants in general. She stated that she was afraid to go to school as a child and despised hiding her true appearance to attempt to fit in. Her torture and experimentation following her assassination of Bolivar Trask only hardened her beliefs towards humans. When once asked by Nightcrawler why she didn't constantly use her abilities to blend in, she replied "because we shouldn't have to". In spite of the tough life she had led, she did possess a sense of humor, which she often expressed when with Magneto. During her imprisonment, she also took enjoyment in using her abilities to annoy her human captors, such as impersonating Magneto when an interrogator asked her where he was. Mystique hates it when people try to dictate how she should live her life, as shown when grew bitter at Charles for insisting that she hide her appearance. For this reason, she felt very alone inside. When she met Hank, she at first thought that she had finally found someone who understood her, but when Hank had developed a serum to counter their abilities, she changed her mind. When Erik encouraged her to be proud of her abilities and not be afraid of judgement, she had finally found what she was looking for: acceptance. This drove her closer to Erik and further from Charles.
