Guggenheim: Hmm... You know, I would say a lot of the story's emotional core comes from Rachel. One of the other things I wanted to do was something that I don't think they really had as much of an opportunity to deal with in X-Men: Kingbreaker was the idea that -- and I guess it was Chris Claremont's third run on Uncanny X-Men -- the Shi'ar Empire was basically responsible for the deaths of all of Rachel's family. I wanted to come up with a story -- all the stories that I pitched to Mike and Dan, I wanted them all to have an emotional through line, so that, in addition to cool set pieces and fun plot, there would be a real, emotional anchor to each of these stories.
For the space story, Rachel and her family history is a big part of her, a big part of the story that deals a lot with themes of vengeance and how one honors the memory of their fallen family. So Rachel's very much at the core.
I would say, as far as the character that's most fun to write, probably Jubilee. I always tend to gravitate and have the most fun with the characters that have a sense of humor to them.
