WARNING: The following contains spoilers for X-Men #9 by Jonathan Hickman, Leinil Francis Yu, Sunny Gho, VC's Clayton Cowles, and Tom Muller, on sale now
Ever since the founding of the Xavier Institute, the X-Men have featured angsty teenagers who are trying to get used to their mutant powers as they deal with their own young emotions. While Charles Xavier preaches love for all mutants, every decade brings a fresh new batch of bright-eyed mutants. However, every generation of young mutants seems to fade into the background when the next generation of X-Men emerges.
While the Children of the Atom are set to become Krakoa's first generation of new mutants, the ongoing X-Men relaunch has gone out of its way to give Marvel's last generation of junior X-Men, the former students of the Jean Grey School of Higher Learning, continued meaningful roles in Marvel's wider mutant world.
Egg
Formerly known as Goldballs, Fabio Medina, was one of the many mutants whose powers manifested after the Avengers' war with the X-Men in Brian Michael Bendis and Chris Bachalo's Uncanny X-Men #1. From the outset, Fabio has been a very likable character, but he's often served as the butt of jokes since his ability to emit golden balls from his chest isn't the most impressive.
However, that all changed with House of X. That series introduced Krakoa's resurrection protocols, where five young mutants use their abilities in a specific way to resurrect fallen mutants. As his new codename explains, Fabio's golden balls essentially serve as the eggs that get this process going. He is now one of -- if not the most important member of -- The Five, which makes him one of the most important mutants on Krakoa and in the Marvel Universe. It's safe to say that Fabio won't be disappearing anytime soon.
Tempus
Eva Bell, or Tempus, was created by Bendis and Stuart Immonen back in All-New X-Men #1, by Brian Michael Bendis. The formerly Australian national was picked up by the X-Men when her time-dilation powers manifested, and she stopped time in a bubble that spanned several city blocks. During her time as a junior X-Men trainee, Eva got unstuck in time and had an entire family in a timeline that was subsequently erased.
Now, Tempus also serves as a member of The Five. Her job within the group is to speed up time through which the cloning process takes place. While she was never seemingly written off as much as her egg-laying peer, Tempus also finds herself among the most important mutants within the Marvel Universe.
Broo
Although he is not a human mutant, Broo is a mutant to his alien race, the Brood, where he's been ridiculed, feared, and hated for being different. In sharp contrast to his mostly mindless peers, the brilliant Broo is capable of understanding compassion, friendship, and love which made him an outcast amongst his species.
Shortly after he debuted in Christos N. Gage and Juan Bobilo's Astonishing X-Men #40, Broo was welcomed into the X-Men's world. While he's spent most of the past few months helping out Black Panther and the Agents of Wakanda, Broo recently crashed back into the X-Men's world in a major way. In Jonathan Hickman and Leinil Yu's X-Men #9, Broo ate the Brood's King Egg, which gave him total control over the rest of the Brood. Now that he's the unwitting ruler of one of Marvel's most terrifying species, Broo is set to become a major cosmic player in the Marvel Universe.
Eye-Boy
Trevor Hawkins manifested his powers as part of the wave of new mutants after Avengers vs. X-Men. For the most part, Trevor's mutant code name, Eye-Boy, sums up his mutant powers pretty well. Trevor is covered head to toe in eyes, which allows him to see in all directions at once. Beyond that, he can see magic waves in the air, has improved marksmanship, can predict incoming attacks, can see microwaves, can see through illusions, has x-ray vision, microscopic vision, and telescopic vision.
Like most of his peers, Eye-Boy began his time with the X-Men as a student at the Jean Grey School for Higher Learning. Although he had a meaningful role in the Age of X-Man, Eye-Boy hasn't been a central character in the age of Krakoa. However, that's about to change with the next incarnation of X-Factor. This iteration of X-Factor will investigate the deaths of mutants who may be up for resurrection, and the team of mutant detectives seems like the perfect place for a mutant who always sees things that other people miss.
While all of the X-Men books have been surprisingly cohesive in the Dawn of X era, the continued prominence of these young X-Men and their peers proves that there really is room for every mutant on Krakoa.
