The X-Men have followed a few powerful leaders over the years, though two driving forces behind the team are founding members, Cyclops and Marvel Girl. They continue to lead the X-Men during the Krakoan age due to their years of experience and powerful mutant abilities. The mutant duo fell in love as X-Men, which opened the doors for children in the future.
The Summers-Grey bloodline is highly coveted by Mr. Sinister because of its potential to produce powerful mutants. Scott Summers and Jean Grey don't have any natural children in the present day. However, there have been a number of powerful descendants from alternate timelines and realities who boast incredible powers.
Updated on October 22, 2022 by Scoot Allan: X-Men like Cyclops and Marvel Girl continue to showcase their incredible powers in events like 2022's Judgment Day. They fight alongside some of their powerful mutant children like Cable and Askani, who each inherited the powerful gifts of their parents. However, there are several other descendants of Scott Summers and Jean Grey across the Marvel multiverse and timestream who've each developed sometimes frighteningly powerful mutant abilities.
10 Tyler Dayspring
AKA Genesis
Tyler Dayspring has a confusing lineage, which isn't surprising since he's the son of Cable. A mutant warrior from the future, Cable married Aliya Jenskot, who had a son named Tyler. Tyler's real father was never revealed, though it was likely Cable's clone Stryfe who possibly assaulted Jenskot while she was his captive. Stryfe would later help corrupt Tyler with Apocalypse's teachings.
Powers/Abilities
- Tyler's adoptive father Cable trained him in warfare and strategy for years
- Genesis could create a psionic link to project emotional memory holograms
- Genesis used Apocalypse's technology and weaponry from his own futuristic era
Tyler would travel back to the present to become an enemy of Cable and one of Wolverine's strongest villains known as Genesis. He possessed limited telepathic abilities that allowed him to view other people's memories and project them. Genesis wore advanced body armor based on Apocalypse's technology, but it failed to save him from Wolverine's berserker rage.
9 Megan Frost
AKA Mind Witch
Chris Claremont crafted some of the greatest X-Men comics of all time. He returned to explore a world where the X-Men aged in real-time. The modern stories in this reality followed the X-Men's children and grandchildren. GeNext and the sequel GeNext: United introduced a few interesting legacy characters of the X-Men, including Meg Frost/Mind Witch.
Powers/Abilities
- Meg inherited her mother's powerful telepathic abilities
- Mind Witch could create powerful psionic links with others
- Her limited telekinesis allowed her to briefly levitate
Megan Frost-Summers was the oldest child of Scott Summers and Emma Frost in this reality. She possessed enhanced telepathic abilities, as well as limited telekinesis. Mind Witch didn't reach her upper power levels, as she was still a young mutant-in-training. However, she displayed a mastery over many psionic abilities because of training her powers with her mother.
8 Ruby Summers
AKA Ruby
Writer Peter David introduced a possible daughter of Scott Summers and Emma Frost named Ruby Summers during his X-Factor run. Ruby was an instrumental part of what was known as the Summers Rebellion. The character also appeared during Secret Wars to fight the evil future version of the Hulk known as Maestro.
Powers/Abilities
- Ruby Summers' optic blasts deliver incredible concussive force
- Her ruby quartz form is similar to her mother's diamond form
- Ruby survived in her ruby quartz form without aging into her 80s
Ruby gained variations of both of her parents' powers. She could generate and project powerful, black-tinged optic blasts. She could also transform her body into a ruby quartz form, which granted her near-invulnerability and immortality. Unfortunately, it's possible that if she reverted to her organic form, she would instantaneously age all the years she spent in her ruby form.
7 Scotty Summers And Raven LeBeau
Earth-1298
Havok is one of the X-Men's greatest and most experienced leaders. After his death, Havok found his consciousness transported into a multiversal counterpart. Alex Summers discovered he had a son named Scotty, with that reality's Madelyne Pryor. Scotty was a mutant with incredible psionic powers that allowed him to manipulate psionic energy from the astral plane.
Powers/Abilities
- Scottie Summers had the potential to reach Celestial power levels, much like Franklin Richards
- He could manipulate psionic energy and had limited telepathic and telekinetic abilities
- Raven LeBeau is an empath who inherited her mother's psionic gifts of telepathy and telekinesis
Havok's Cerebro unit also identified Gambit's adopted daughter Raven LeBeau as an Omega-Level mutant with the potential to be the most powerful mutant on the planet, but her powers were only teased. Raven was actually created by Sinister using the DNA of Alex Summers and Jean Grey, further proving the potential power of the Summers-Grey genes.
6 Nathan Daysping Summers
AKA Cable
Nathan Summers/Cable is the son of Cyclops and a clone of Jean Grey named Madelyne Pryor. Mr. Sinister created Pryor after the "death" of Grey so he could have a weapon against Apocalypse. Young Nathan was that weapon, but Apocalypse soon infected the baby with the techno-organic virus. A warrior from the future took Nathan to her time to save his life.
Powers/Abilities
- Cable became the world's most powerful telepath after overcoming the T/O virus
- His unhindered telekinesis was capable of lifting an entire floating city without effort
- Cable could teleport or "bodyslide" using the advanced technology in his bionic arm
Nathan would grow up and have a life in the X-Men's future as Cable. Unfortunately, he was still infected with Apocalypse's T/O virus. Cable kept the virus at bay due to the incredible levels of telekinetic and telepathic power at his disposal. However, the constant need to fight the T/O virus reduced his active power levels.
5 Rachel Summers
AKA Askani
Rachel Summers is the biological daughter of Scott Summers and Jean Grey from one of Marvel's most terrifying alternate timelines. She grew up in the "Days of Future Past" timeline, where Sentinels ruled over mutant concentration camps. Rachel traveled back to the present to prevent her apocalyptic timeline from existing.
Powers/Abilities
- Rachel's powerful telepathy made her the perfect host for the cosmic Phoenix Force
- She is also a high-level telekinetic who can intuitively rearrange and alter matter
- Askani can travel through time by "chronoskimming" into her past and future selves
Like her mother and half-brother Cable, Rachel is an incredibly powerful psionic. Unfortunately, she lacked the training the rest of her family received. Rachel also developed a connection to the Phoenix Force, like many members of her family. This drove her potential power levels up, despite her initial lack of training.
4 Hope Summers
AKA Mutant Messiah
Hope isn't related to the Summers or the Greys by blood, but she's still a powerful member of the family. She was the first mutant baby born since Scarlet Witch uttered "No More Mutants" during the House of M event. Hope's life and the future of mutantkind were in danger, so she was sent into the future along with Cable.
Powers/Abilities
- Hope can mimic and augment the powerful abilities of more than one mutant at a time
- Her power to amplify other mutants' abilities drives the Krakoan Resurrection Protocols
- Cable trained Hope in survival and warfare across a few different post-apocalyptic futures
Hope became Cable's adopted daughter, and the two spent years surviving in the future before returning to the present. Hope's powers to mimic and enhance other mutants' abilities manifested when she returned during the Second Coming event. She is also connected to the Phoenix Force, which allows her to draw from the energy of the cosmic force.
3 David Richards
Hyperstorm (Earth 2600)
David Richards appeared in a variation of the "Days of Future Past" storyline. He first appeared in the pages of the reality-hopping Exiles. David was the son of Rachel Summers and Franklin Richards. The cosmically powered Franklin Richards was the child of Reed and Sue Richards of the Fantastic Four.
Powers/Abilities
- David inherited incredible psionic potential from his parents, along with telepathy and telekinesis
- He can mimic the abilities of other powered beings and has manifested the Phoenix Force
- Sabretooth, from the Age of Apocalypse reality, trained young Richards in strategy and battle
David was a powerful psionic who could manipulate reality. He had the potential to become more powerful than Magneto, Professor Xavier, and the Phoenix Force combined. Richards' power levels never reached the prophesied extreme levels. The Exiles Sabretooth killed his young charge to end David Richards' potentially cosmic threat.
2 Nate Grey
AKA X-Man
Nate Grey/X-Man has a similar origin to Nathan Summers/Cable, but his creation began in the Age of Apocalypse reality. Mr. Sinister genetically combined the Summers and Grey bloodlines to create Nate, and he grew the powerful mutant artificially to near adulthood in a lab before Nate escaped. The AoA timeline died, but Nate Grey escaped to the mainstream universe.
Powers/Abilities
- Nate developed immense telepathy and telekinesis that evolved to reality-warping levels
- He gained incredible control over his abilities when he became a multiversal shaman
- Nate Grey transformed into a powerful psionic entity, which further increased his powers
Unhindered by the T/O virus that ravaged his "brother" Cable, X-Man's powers continued to grow and evolve. Nate's pure genetic stock (Cable's mother was a clone) allowed for nearly infinite levels of power as one of the X-Men's strongest omega-level mutants. Nate displayed a new level of power when he created an entirely new reality during the Age of X-Man event.
1 Jonathan Reed Richards
AKA Hyperstorm (Earth 967)
Jonathan Reed Richards is also the son of Rachel Summers and Franklin Richards. He appeared in yet another variation of the "Days of Future Past" timeline. Jonathan's incredible psionic powers allowed him to become one with Hyperspace and control the fundamental forces of reality, becoming an incredibly powerful threat only Galactus could defeat.
Powers/Abilities
- Richards can access infinite psionic energy from Hyperspace to manipulate reality
- He is also a powerful telepath and telekinetic like most of the Summers/Grey kids
- Hyperstorm took over his post-apocalyptic world and other planets in his universe
Both overpowered Hyperstorms prove that the Summers and Grey genes are incredibly powerful. However, they can be very dangerous when combined with Franklin Richards's already phenomenal power levels. Growing up in the dark "Days of Future Past" timeline also didn't help create well-rounded altruistic heroes.
