Character: Samuel Guthrie (aka Cannonball)
Played-By: Ryan Kwanten
Arrived on Muir: Thought dead after torture at a concentration camp, he was discarded into the Cumberland River in Kentucky. Sam woke and flew directly to Muir.
Differs from canon: Went to Xavier’s for college, never hired out as a mercenary or went on undercover assignments. Is not rebellious. May or may not be an External.
Character: Nathan Dayspring AKA Cable
Played By: Gerard Butler
Arrived on Muir: Sent there by Xavier to aid in his recovery after his arrival from the future. Has not yet been forgiven by Sage for shipping them there freight-class.
Differs From Canon: From the future, but so far as anyone knows, not a Summers spawn or a messiah of any stripe. Involved with Sage. Field leader of the Muir X-Men.
Character: Clint Barton (aka Hawkeye)
Played-By: Jensen Ackles
Differs from canon: Mix of standard and Ultimate canon. Started as an antagonist toward the X-Men, not the Avengers. Defected from the Avengers due to MRA in homage to his opposition to the SRA in standard canon.
Character: Lorna Dane (no code name yet)
Played by: Sienna Miller.
Arrived on Muir: After being broken out of an internment camp by Remy LeBeau.
Differs from canon: Still a geology geek from an upper-class adopted family, still has a thing for Alex Summers. No known ties to Magneto. Has an ex-fiance who went missing after the MRA passed, and spent three years in a California internment camp after her mutation was discovered.
Character: Victor Borkowski (no codename)
Played By: Oliver James
Arrived on Muir: Technically didn’t. Victor and his mom immigrated to Duninnean soon after the Mutant Registration Act passed and, though both live and work in the village, neither one has had any occasion to spend time on Muir.
Differs from canon: Still has the lizardy looks, prehensile tongue, and wall-crawling abilities, hasn’t discovered his camouflage yet. His arms are still symmetrical. Victor is still a schoolboy trying to figure out his sexuality, and his crush on Jean-Paul confuses him more than anything else.
Character: Jono Starsmore aka Chamber
Played-By: Luke Grimes
Arrived on Muir: After being rescued from a Dept. H laboratory with Northstar, following an unsuccessful escape attempt.
Differs From Canon: Was at Xavier’s for about two years before the MRA passed, and spent two years as a prisoner of Department H after he left the team (which is where his powers fully manifested and blew off half of his face and torso). Has concentrated on honing his modest telepathic abilities. Involved with Jake Gavin and Jean-Paul Beaubier. Teaches music theory at the Dunninean schoolhouse. Being totally emo about his ex, Paige, is still a universal constant, though.
Character: Alex Summers aka Havok
Played-By: Channing Tatum
Arrived on Muir: After Cyclops and the X-Men broke him out of the military prison in which he was being held after The Great Headache of X2 inadvertently triggered his powers and cause him to vaporize a bunch of his fellow soldiers.
Differs from canon: Ex-military and didn’t meet Lorna Dane until just recently, but otherwise pretty close — still the youngest Summers brother, still a big geology nerd, and still has all of his sibling issues intact (especially since our lead sadist smashed Cyclops’ US-based team, powers, and mental stability to bits with a sharp rock recently).
Character: Nathaniel Grey (no alias)
Played-by: Thomas Dekker
Arrived on Muir: After washing up on the shore following a cross-dimensional jaunt.
Differs from canon: Not a shaman (yet?). Involved in a relationship with Laynia Petrovna. Slightly less emo than canon. Has Maddie Pryor living in his head.

Character: Lillian Crawley-Jeffries aka Diamond Lil
Played-By: A brunette Malin Ackerman (sometimes as Silk Spectre II)
Arrived on Muir: in the belly of a freight ship. With two kids under the age of ten. And no alcohol.
Differs from canon: She’s alive but Madison is (presumed) dead. They have two kids together named Evelyn Rose Jeffries (Evie) and Madison Jeffries Junior (JJ). Hates Alpha Flight. Still a kick ass, hard-headed, good time girl at heart, though.

Character: Warren Kenneth Worthington III no aka yet
Played-By: Leif Stacey
Arrived on Muir: After outing himself to save his kidnapped ex-girlfriend and being betrayed by his oldest friend.
Differs from canon: This Warren Worthington is a successful businessman by age twenty-five. He’s not a cherafayim and does not have a blue form. He’s also not a dumbass and will never have flying sex with Paige Guthrie, but he will still probably have a crush on Jean Grey. But he is still wealthy, headstrong and an arrogant S.O.B. if you cross him.
