These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Cyclops has been hit with a lot of this over the years, both by fans and by writers. Depending on the Writer he's either a kind, compassionate man who simply suffers from bad social skills or he's a stubborn Jerkass control freak who may or may not have developed some very bigoted disdain towards the humans who have persecuted him and his fellow mutants.
Base Breaker: Quite possibly the champion Base Breaker among X-Men characters and fans along with Wolverine, due to the number of times he's fallen into the hands of writers who either don't like him, don't understand him or both, or who dismiss him simply for being "that guy who isn't Wolverine" or "that guy who doesn't get along with Wolverine", and even now branching over into other characters, usually other heroes, being derailed just so he can look better by comparison.
Creator's Pet: Played straight when written by Matt Fraction, who many feel made his run pretty much a love-letter to him. Inverted, however, by Craig Kyle and Jason Aaron. With Kyle, in some of the works with is writing partner Chris Yost (such as X-Force and Wolverine and the X-Men), Cyclops tends to be incompetent, moody, and generally unlikeable, but whenever Chrs Yost handles him by himself, and even some works with Kyle, Cyke tends to be much more balanced and likeable, making it apparent this is Kyle (similar with the level of violence too; whenever Kyle is involved, Yost's work is much more bloody and violent). Meanwhile, with Jason Aaron, he's penned two big storylines (Schism and Avengers vs. X-Men) involving Cyclops, both of which involve Wolverine (and in AVX, Captain America) giving Cyclops a "The Reason You Suck" Speech after he crosses what is supposedly the Moral Event Horizon, with the end being Cyclops left with a large group of his former team, and the superhero community in general, hating his guts. Meanwhile, in his contributions to Battle Of The Atom, both Wolverine and Storm spend notable moments reminding him and the viewer that they don't like him and think he's crossed the line, without explaining why. With Kyle its arguable to say this since its only really bad in WATXM, but Aaron, at this point its pretty clear he seems to enjoy having characters hate him.
Designated Villain: Is frequently blamed for everything that goes wrong simply because he's the only one to step up to the plate and accept responsibility.
Ensemble Darkhorse: While Big Scott still counts as a Base Breaker despite his large increase in popularity since Av X, Young Scott's status as The Cutie and a Badass Adorable has managed to win around a large number of people to his side, even, strangely, a contingent of people who hate on his older self. The fact that his solo is amazingly drawn and written possibly helps too.
Fridge Horror: Scott's relationship with Emma Frost becomes a lot less romantic when you remember that its foundation was built on frigging Mind Rape.
Informed Wrongness: Jason Aaron loves to have characters hate on Cyclops. In Schism, Wolverine and mutants siding with him break off from Cyclops. Wolverine cites that children shouldn't be trained to fight... Readers are quick to point out that the X-Men have always trained kids to defend themselves, and that, at the time of Schism, mutants were near-extinct, and anti-mutant violence was at an all-time high. It doesn't help that Wolverine himself makes a point of taking a teenage girl under his wing every decade or so. Especially mind-numbing is the fact that Wolverine's plan is essentially to run way and hope they escape, and to encourage them to run he rigs the whole island to explode. In the end, the students start fighting off the Sentinel while the two fight, and when they realize this, Wolverine abandons his plan to help do the exact thing Cyclops said they should...and yet in the end, instead of admitting Scott was right, he leaves, because Scott is making the students fight their battles (despite the fact that, if he doesn't let them fight, them and everyone else will die).
In the aftermath of Avengers vs. X-Men, Aaron makes it a point to have characters get angry at and insult Cyclops literally whenever they meet, even characters that don't hate him in other books, and regardless of the current situation. Characters have called out Cyclops for training his students to fight and taking them in his missions... Which the X-Men do fairly often. Readers are quick to note that Cyclops' students are all college aged or older. Hell, after Cyclops shows concern for Wolverine and saves his life, Logan decides to be a dick to him.
Iron Woobieand Stoic Woobie: Scott's gone through so much shit in his life its not a surprise he can be a bit of a dick sometimes. Still, his recent actions to protect what's left of the mutant race comes from the fact that the mutant race is the only thing he has left to fight for. People's reactions, at large, to Avengers vs. X-Men seem to mostly be sympathy to Cyke.
Both young and old Cyclops in All-New X-Men also become major woobies by the fifth issue. Old Cyclops has to deal with even his own team hating his guts, his former family hunting him, and the world at large wanting him dead, for actions he did while not in control of his own body, all the while he's trying to do good, but all his actions are demonized. Young Cyclops, however, has to deal with his friends freezing him out, the knowledge that he's going to degenerate into a seemingly mess that killed his father figure, and all the present day X-Men looking at him with a contempt due to their hatred of his present self that he just does not understand. It does not help that as time goes on, he increasingly notes the glaring flaws in his detractor's philosophy, and the extenuating circumstances in his future counterpart.
It Was His Sled: His involvement in some (if not all) of the most prominent, memorable, and/or classic X-Men stories means that any one familiar with comics in the least probably knows a lot about him.
Magnificent Bastard: Solidified in Curse of the Mutants. To add some context, Utopia was surrounded by Vampires, fighting on every side and platform. Jubilee and Wolverine have both been turned, and the latter is standing only a few feet away, ready to cut his head off and turn the rest of the X-Men. Cyke's response? Pulling out a control to reactivate Wolverine's Healing Factor, turning him back. That's right, Scott discovered he was immune to vampirism and that the vampires wanted to turn him, so he deactivated his Healing Factor and allowed him to be turned, just so he could turn him back right when they were relying on him to lead their forces. The vampires, still in shock, are promptly slaughtered. Meanwhile, Scott's earlier plan, to bring back Dracula and have him take back the vampire horde, appeared to have failed and was forgotten...only for it to turnout Dracula had been tracking down Xarus all this time, and after curbstomping his son and taking back his place, Cyke warns him that he could kill him with the push of a button. Dracula claims that he knows he's bluffing, but still lets them leave in peace. In short, do NOT threaten the safety of Cyclops' people, and when he says that he will slaughter you, he means it.
And more recently, 'Cyclops was Right', notably since Cyclops, in the hands of Kieron Gillen, actually mentioned it in-story.
Never Live It Down: Despite the sheer amount of leadership and badassery Scott had shown, he can never take a break for his screw-ups that the writers had piled on him, which is the usual ammunition of his haters in favor of his clawed rival.
"Abandoning" his wife Madelyne Pryor and son Nathan Summers to search for the resurrected Jean Grey.
Being involved with a psychic love affair with Emma, while married to the psychic Jean.
Killing Charles Xavier during a psychotic rampage while possessed by the Dark Phoenix.
Rescued from the Scrappy Heap: While Cyke was always more of a Base Breaker than a Scrappy, Post-AVX, he seems to have shot up in popularity, possibly usurping Wolverine (Going by recent sales, Uncanny, Scott's book, has nearly double the sales WATXM has, though that might be due to Brian Bendis writing and its lower issue count (Wolvie's series was in the 40s before relaunching). Due to the Designated Villain treatment he got and is still getting, combined with his genuine attempts at helping people and apparently being the only one bothering to reach out and help any of the newly awakened mutants, and the fact he's the only one who tries to suggest peace rather than tossing insults and fighting whenever he runs into the people who currently dislike him, despite it being them we're apparently supposed to root for. Notably, when Cyclops popped up in WATXM to help Wolverine fight off sentinels, fans actually cheered Cyclops on and called for him to Just Shoot Him now that Wolverine's without his Healing Factor since Wolverine was being such a huge dick to him (which he did literally the second after Scott saved his life).
Ron the Death Eater: While Cyclops may not be perfect and he makes his share of mistakes, but as an A-List superhero team leader, that's bound to happen. However, as far as some writers, fan or professional alike, are concerned, he's the most despicable person on the planet. Despite being brainwashed at the time, people are blaming him and solely him for the state mutants are in now, despite mutants always being in this kind of situation. Then there's the fans who complain about the fact he blames Wolverine and the Avengers, or the dark Phoenix, instead of accepting blame himself...despite the fact that he still accepted responsibility, and is the only one in the mess who's accepted any blame in the whole mess (accept for Captain America, who at least admits he hasn't done enough to help mutants), while the opposing side hasn't and continue to blame him for everything.
Ship-to-Ship Combat: Where to even start? Cyke/Jean vs. Cyke/Emma is probably the biggest battle in the fan base, the former being iconic while the latter some fans find far more interesting, and still others remember him fondly with Madelyn Prior. That's not even getting into Ho Yay with Angel and, of course, Wolverine. Now there's also the fact that some writers have decided that the Phoenix Force itself wants him. Then of course is Mr. Sinister, who has long displayed an unhealthy obsession with Cyclops within the books leading to quite a bit of subtext among fans. More recently, Uncanny has seen Tempus, Maria Hill and even Magik enter the fray. And that's not even including Teen!Scott in All-New, who is popularly linked both with the obligatory Jean Grey (in this case time-displaced O5 Teen!Jeen) and, thanks to Rule63 giving the fanbase an outlet for Adult!Scott's subtext with Logan, X-23. The one thing all of the fans seems to agree one is that Scott loves to hook up with crazy people that would love nothing more than to dominate and break him.
