We already know a younger incarnation of Jean Grey is slated to return to the Marvel Universe courtesy of Brian Michael Bendis and Stuart Immonen's "All-New X-Men" title, but this Adam Kubert-illustrated teaser for the soon-to-wrap "Avengers Vs. X-Men" hints at to possibility of a more mature -- and much more dangerous -- version of the character set to make her presence known as well.
With the Phoenix Force being at the center of the AvX crossover's conflict, it's not exactly a surprise to see someone take on the mantle of the Dark Phoenix. Of course, it remains to be seen whether this is a resurrected Jean Grey, the original Phoenix Force returning in Jean's form as was revealed to have been the case in the original Chris Claremont/John Byrne storyline or an entirely new incarnation of the Dark Phoenix. The answer will be revealed in October's final issue of "Avengers Vs. X-Men."
