James 'Logan' Howlett/Wolverine
Piotr Nikolaievitch "Peter" Rasputin/Colossus
A detective and heir to a castle and fortune in County Mayo, Sean Cassidy was a former Interpol inspector with flight and sound manipulation abilities. After his wife died in a terrorist bombing, he blamed his cousin, causing him to run off with his daughter and driving a rift between the two. He was mind-controlled by an alien terrorist group but freed by the X-Men. Later, he joins the X-Men when the original five are kidnapped. Being about 10-15 years older than the rest of the recruits, he was only active for a short amount of time but still hung around as a reserve and as a mentor, who applied his experience in espionage and anti-terrorism to the younger members of the group. Deceased in 2005, he was briefly resurrected in 2013 and became a Horseman of Apocalypse. In 2019 he seems to be entirely restored, whereas he was a weird zombie previously before being outright killed again in Uncanny X-Men (2018).
- Berserk Button: Don't hurt Moira. As Guardian found out, even if it's an accident, Banshee will try to kill you.
- Bound and Gagged: A few times, due to his vocal abilities.
- Cain and Abel: With Black Tom Cassidy, his cousin (or brother, in some continuities).
- Captain Ethnic: Wears green, ginger hair, 'faith 'n begorrah'.
- Depower: Went a long time without his powers after saving Japan from an earthquake machine. And again after Mystique slashed his throat in the early 00s.
- Depending on the Artist: Even in comparison to other X-Men of his generation. He went from ugly in the Sixties to handsome in the 70s, his hair inexplicably changes colour in the 80s (he started out blond) and he started looking younger in Generation X in the 90s.
- Disappeared Dad: For his daughter, Theresa Cassidy, though in all fairness to Sean, he didn't know she was alive, or that his wife had even been pregnant in the first place, and his cousin made sure he remained unaware.
- Distinguished Gentleman's Pipe: Sean smokes a pipe when he's relaxing. Although he seemed to have given up by the time he became a teacher.
- Dropped a Bridge on Him: Or rather, a 747. He came back, but took a surprisingly long time for an X-Man.
- Drowning My Sorrows: He took Moira's death poorly.
- Gender-Blender Name: "Banshee" (bean sí in Irish) literally means "fairy woman", so a male banshee is a contradiction in terms.
- Handicapped Badass: Sean for a time in the early 90's courtesy of a broken jaw preventing him from using his powers.
- Heterosexual Life-Partners: With Forge. They're practically brothers.
- Hidden Depths: Has a deep appreciation of American Country and Western music.
- I Believe I Can Fly: Attempted to explain as him riding on soundwaves. No, just... no.
Wolverine: Next time, why don't we try sneaking in with a marching band?Banshee: If you think that's bad, you should hear me sing...
- It came with a Funny Moment in the TV series, when he gave Wolverine a ride, Wolverine covering his ears for the whole journey.
- I Choose to Stay: After the Proteus saga, Sean stayed behind on Muir Island while the rest of the X-Men went back to America, partly because without his powers Sean wasn't much use to the team, and also because of Moira.
- Love at First Sight: Fittingly, when he first saw Moira, he was rendered speechless.
- Make Me Wanna Shout: His power allows him to use sonic waves to both attack and to fly.
- Make Some Noise: In addition to the standard sonic scream, he can also "tighten" sound around him to create a barrier, use sonar, and change the tones of his voice to make it more persuasive and subtly influence people.
- No-Sell: As with Cyclops and Havok, Sean and Tom's powers don't effect the other, so their fights usually revolve around them fighting the old fashioned way.
- Officer O'Hara: Before becoming a superhero, he was an NYPD cop.
- Oireland: There's stereotypically Irish, and then there's literally owning a castle full of leprechauns.
- Older and Wiser: Than the rest of the All-New X-Men, save Logan.
- Progressively Prettier: In his first few appearances, he was uncomfortably close to the 19th century "Irish neanderthal" stereotype. When he joined the X-Men, he was intentionally redesigned to appear more handsome.
- Reality Ensues: As with most long-running comics, it varies, but at several points it's shown that smoking does not go well with voice-based powers. (When the team clashes with Alpha Flight, he accidentally gives himself a coughing fit so bad Ororo thinks he's being attacked.)
- Retired Badass: Quit active heroics to teach the younger students.
- Worf Had the Flu: One of the reasons given for his death was that his throat had been slashed by Mystique some years before, and he wasn't entirely up to his full strength at the time.
Sunfire got his powers from his mother being poisoned by the radiation from the bomb dropped on Hiroshima. He vowed to use his radiation powers to fight a one-man war of revenge on the U.S., with the help of his Manipulative Bastard uncle Tomo. After his uncle revealed his true colors by murdering Sunfire's father, he surrendered himself to authorities. He was invited to join the new version of the X-Men, but only agreed to be on reserve status, because his temper and radiation powers combined means he doesn't play well with others.
- All Asians Know Martial Arts: His Evil Uncle Tomo made sure he got a good training in martial arts. He is competent enough to fight back against several opponents without using his flame powers, which Rogue found impressive.
- Anti-Hero: Shiro is rude, belligerent, more than a little racist... but he also loves his country and will do anything to defend it.
- The Atoner: Started drinking out of regret for his time as a Horseman of Apocalypse and was talked into becoming an Avenger by Wolverine so he could find a redemption.
- Big, Screwed-Up Family: Its rarely pointed out in his appearances (due to him being relatively secondary character), but his family is really messed up:
- First there is his Evil Uncle Tomo who forced him into hating USA and killed his father.
- Then there is his other Evil Uncle Shingen, a crime boss who was really abusive towards his daughter Mariko. He was killed by Wolverine.
- Mariko herself became a crime boss despite being one of the nicer people in her family. She was killed by another crime boss, but recently she got better and became anti-heroic Scarlett Samurai. Mariko and Wolverine also had a foster daughter Amiko.
- Then there is his paternal half-sister Leyu who had exactly same powers. And outfit. And she called herself Sunpyre. She was killed by Mystique a year after being introduced.
- Then there is his super villain cousin Silver Samurai, whom he tried to help to become a hero, but failed, which resulted in a conflict between cousins. After Samurai was killed, his son Shin took up his name and became a super villain himself. Sunfire once fought him with Wolverine.
- He also had a cousin Yoshi who died because of drug addiction.
- Brainwashed and Crazy: Apocalypse brainwashed Shiro to make him a Horseman of Famine. Emma Frost freed him from Apocalypse's influence, but he then joined Mr. Sinisters Marauders for a short time.
- Captain Ethnic: He's from the Land of the Rising Sun, his codename is Sunfire, and his powers are basically solar radiation.
- Changed My Mind, Kid: During Giant-Sized X-Men, he agreed to join Charles's new X-Men team, but the minute he hears about what's happened loudly and angrily storms out... only to catch up with the team on the way to Krakoa, still grumbling and complaining the whole way.
- Clashing Cousins: His cousin is the criminal Silver Samurai. He tried to help him to reform, but was eventually betrayed by him.
- Combo Platter Powers: He is able to fly, controls fire and has some radioactive powers. In his short time as Famine he could also make enemies suffer from hunger.
- Crimefighting with Cash: Comes from a very wealthy Yashida clan which has political ties.
- Distaff Counterpart: His paternal half-sister Sunpyre. Who just happens to have exactly same power set and costume.
- Evil Uncle: Not one, but two. The first one is Tomo who made him attack USA and later killed his father, the second is Shingen who is a crime boss.
- FaceHeel Turn: After House of M, he became a horseman of Apocalypse (not willingly), but after he broke off the brainwashing, he willingly served Sinister for a time.
- Fantastic Racism: Hating Americans was much of his characterization during his early appearances, but it became downplayed nowadays.
- Fire-Forged Friends: Developed this dynamic with Rogue during her solo series.
- Flight: His powers include the ability to fly (he even flew in space couple of times).
- Hand Blast: Shoots plasma beams.
- Handicapped Badass: His legs are now cybernetic due to Lady Deathstrike cutting them off.
- HeelFace Revolving Door: At first Shiro was shortly presented as antagonist, then became an X-Man (for about ten minutes) and Japan's beloved hero, then he got brainwashed by Apocalypse, then joined Mr. Sinister's Marauders and finally became an Avenger.
- Heroic Sacrifice: Attempted twice in Uncanny Avengers. Not only did Shiro survive both attempts, he actually got a power-up after the second one.
- Hot-Blooded: Shiro is extremely hot-tempered (no pun intended). He is usually the one who starts a fight without conversation. Also hes not quite a good team player exactly for this reason.
- I Love Nuclear Power: While the original explanation for mutantkind was nuclear power anyway, Shiro is one of the few with a confirmed connection to it - his original origin was that his mom was at Hiroshima (Comic-Book Time means this obviously doesn't work anymore).
- Immune to Bullets: Once melted the bullets after some gangsters tried to shoot him down. Averted when Wild Child injures him with bullets.
- Ineffectual Loner: Due to his arrogance and love of working alone, he was never a really good team player. However, he often uses the help of other heroes when he knows he cant handle by himself. His team-ups include Iron Man, Sub-Mariner and, of course, the X-Men (particularly Rogue and Wolverine).
- Jerkass: Like Quicksilver, he's sometimes a good guy, sometimes a bad guy, often straddles the two lines and jumps between them even more often at times. The one thing that you can count on is for him to be unbelievably rude, obstinate, and just plain obnoxious; regardless of the side that he takes, he's invariably going to be that one guy that no one on the team likes.
- Jerk with a Heart of Gold: It's in there. Just don't expect him to show it. Or admit it. Case in point, the first time readers meet Mariko, she tells Wolverine her cousin had often spoken about the X-Men with respect. All we'd seen of Shiro was him blustering and insulting them the whole time, before storming out.
- Leeroy Jenkins: He's usually the first to get into battle, which gets him into trouble fairly often. Cost him his legs in the confrontation with Lady Deathstrike.
- My God, What Have I Done?: After he finds out what his uncle did...
- No Good Deed Goes Unpunished: When abducted by Apocalypse, Shiro chose to crawl through his base and try to rescue Gazer, another mutant Apocalypse had abducted. Unfortunately by the time Shiro got there Gazer's brainwashing had already sunk it, and Shiro was subsequently brainwashed himself for his troubles.
- One-Hit Kill: Well, not a kill (however it would be, had it been someone else opposing him), but the way he managed to beat Sabretooth with one punch is really impressive.
- Patriotic Fervor: Japan's national hero and very proud of his country.
- Person of Mass Destruction: His nuclear powers and Alpha-level mutant status make him this. After his power boost in Uncanny Avengers he was the one to destroy a space ship with the highly powerful Apocalypse Twins on the board and his Age of Apocalypse counterpart was capable of destroying a city and injuring Apocalypse no less.
- Playing with Fire: His solar-powered energy blasts are extremely hot.
- Politically Incorrect Hero: He's incredibly racist. In the 70s, he was also sexist on top of that.
- The Power of the Sun: Well, what do you expect from someone who goes by Sunfire?
- Took a Level in Badass: First after becoming the Famine, second after getting power boost during his battle with Kang and the Apocalypse Twins.
- Took a Level in Kindness: While still kind of a Jerkass and his traits really Depending on the Author, Shiro seems to become much more level-headed than he was in his early appearances and especially during his Marauders days. For example, during his first encounters with other X-Men he constantly insulted his allies and was known more as a loner. Nowadays he seems to be less rude and caring more about his teammates. He even sincerely apologized to X-Factor after he was brainwashed into attacking them and befriended them after, something he would never have done in the 70s. He also seems to have developed good relationships with some other mutants, including Wolverine, Rogue, Gambit and Polaris.
- We Used to Be Friends: Didn't want to believe Rogue that his cousin Silver Samurai betrayed him and tried to reason with him before Samurai attacked them.
- Would Hit a Girl: Punched Rogue at least on two occasions.
- Wreathed in Flames: His appearance from Decimation onward had Shiro looking like his Age of Apocalypse counterpart, though with the slight difference of still having his skin.
Thunderbird I/John Proudstar
An Apache Indian and Vietnam veteran with the mutant abilities of superspeed, strength, and invulnerability - and super-tracking which was basically a standard requirement for all Native American superheroes throughout the 20th century. He joined the X-Men solely for excitement and glory, despite resenting "the White Man". He died in vain, and acted against orders - trying to keep a minor supervillain from getting away, causing a plane crash that he did not survive. His younger brother, James Proudstar (Warpath), would eventually become a member of the X-Men and X-Force.
- Anti-Hero: The major factor leading to his character's death. Claremont wanted to kill off one of the characters early in his run (for the shock value, apparently), and Thunderbird was chosen because, as Claremont put it "everything he had, Wolverine had too, plus claws."
- Does This Remind You of Anything?: The Classic X-Men reprint series included a new backup story in which the X-Men react to his death, and while the word "suicide" is never used it's clear that they think it was exactly that. Storm and Nightcrawler remember times when he seemed obviously troubled and wish they had reached out to him, Banshee wonders "what demons drove [him] to such a mad decision", and Wolverine concludes that he "checked out" because of something that happened to him while he was a Marine.
- Dramatic Irony: A flashback had Logan ruminating that John would likely last the longest of all the new X-Men.
- Famous Last Words: "I'm a man, a warrior of the Apache, and today, I'm going to prove it!"
- Ineffectual Loner: Not to mention a total dick.
- Jerkass: Like Sunfire, he was rude as hell, completely unwilling to work with others, and just generally not a pleasant person.
- Jerk Justifications: An issue of Classic X-Men suggested Thunderbird was initially genuinely interested in becoming an X-Men, and on his first night Iceman attacked him in a fit of childishness, bringing John back to square one.
- Leeroy Jenkins: Basically, if he hadn't been an impetuous moron, he'd probably still be alive today. He was, however, and his decision to jump onto a moving jet to stop a villain from escaping wound up being the bit of blind idiocy that killed him.
- Lightning Bruiser: Superhumanly strong and quite fast as well.
- The Nicknamer: Tended to refer to Cyclops as "One-Eye".
- Not So Invincible After All: Dies on his second mission, having been previously thought of as effectively invulnerable.
- Positive Discrimination: Notably averted; apart from having a terrific set of Combo Platter Powers, he was a stone cold Jerkass who meshed poorly with the rest of the team, and paid dearly for it.
- Proud Warrior Race Guy: His sole driving motivation with the team was to prove the Apache were still a strong people.
- Sacrificial Lamb: Killed off in his third appearance.
- Senseless Sacrifice: The supervillain whose jet he was killed bringing down? Still around today, and way more powerful than he was back then.
- Shell-Shocked Veteran: Classic X-Men revealed that he had lied about his age to join the Marines, and returned home from war with some major issues as a result. It's strongly implied that his [PTSD] was a factor in the recklessness that got him killed.
- Super Strength: Not as strong as Colossus, but strong enough to stop a running bison.
- Teeth-Clenched Teamwork: He was questioning his decision to join the team up until his death.
- We Hardly Knew Ye: Lasted a grand total of three issues. Even flashback issues and retcons haven't been able to add much, since his time with the X-Men was so short.
