Named after a track by ‘90s gonzo rock contenders Monster Magnet and created by Grant Morrison and Frank Quitely in the comic-book run, Negasonic Teenage Warhead’s real name is Ellie Phimister. Her mutant powers may extend to telepathy, a skill she learnt under Emma Frost’s tutelage. If you think her codename is a little, well, out there, Kitty Pryde would probably agree. “Wow, we really have run out of names,” she jokes in one of the comics. Not, on this evidence, that you’d want to say that to her face.
