New X-Men: Academy X / New X-Men Vol. 2 (2004-2008) #42

Plot

Mutants are now an endangered species, and the New X-Men realize that they may well be the LAST X-Men! After the events of "Quest for Magik," several of the kids have been changed forever, and the Astonishing X-Men are finally taking some time to get to know their students. But after everything the team has been through? who even wants to be an X-Man? New powers, new relationships, new team members, all on the road to the X-event of the decade! Tired of dead ends with current mutants, Beast turns to the family that has sired the most mutants on Earth—the Guthries. The family that produced two X-MEN and may hold the key to save the mutant race.
