Just hand over the motherhood role to Emma, she can not do worse then Jean. Rachel Grace Frost Summers, her final code name Ruby.
This post is made for me to get some lols at a friend who wants to see Ruby.
Jean is featured as Phoenix in movies, cartoons, and video games so all future use of the Phoenix is with Jean.
Other problem is the XMen have a surplus of telepath/telekinetics. Psylocke is a ninja and makes psychic weapons so her application of her powers is very different from Jean’s. Monet uses her supergirl powers more than her tp/to. Cable uses his guns, fighting skills, and tech.
Her character suffered twice because she was brought in the XNen to replace Jean when Jean was dead. At least Hope has an unique power set, and enough of her own identity.
She was pretty good in Excalibur. As long as she stays away from Jean, she can do pretty well. She can work with Scott, Wifi, Wolverine and it can all turn out great as long as Jean Grey doesnt get involved. Another interesting path would be her joining Emma/Selene/Madelyn as an antagonist or a non-heroic role.
