I am Negasonic Warhead. I was born Ellie Phimister. I'm a member of the X-Men and a mutant who can generate atomic bursts from my body. After spotting you on the news, I went to go see you in an attempt to convince you into joining the X-Men. However, you declined and ended up fleeing from me. Later, you would return in an attempt to save me by defeating Ajax. During the ensuing fight, I used my powers to take out multiple soldiers and save you from getting strangled by Angel Dust.
