The most convoluted X-Man this side of Wolverine, Jean was the final addition to the original team. She stuck around through the Uncanny years, got swapped out with a space bird goddess, appeared to die, resurfaced in Jamaica Bay, founded X-Factor, went back to the X-Men, died for real, and just recently came back again.
There are a lot of jokes about Jean’s frequent deaths and rebirths, but there really aren’t that many. And I’m actually glad she’s back since she serves a great purpose in modern X-Men comics. Plus, Jean’s been dead since, like, the Morrison run so maybe after 15 or so years without her, she has a place waiting for her in the X-Men universe again.
