* {{Anvilicious}}[=/=]SomeAnvilsNeedToBeDropped: The series covers several heavy topics related to Post Traumatic Stress Disorder and Gender Identity primarily, with an odd combination of ham-handed and nuance. Post Trauamtic Stress Disorder, for instance, covers not just war, but assault and torture; and Gender Identity issues include bisexuality and whether or not [[spoiler: the attempted sexual assault that awoke Striker's powers also 'caused him' to be gay.]]
* BaseBreaker: Juston, not because of his personality or gimmick but because his RobotBuddy is a [[MookFaceTurn Mook-Face Turned]] Sentinel. This fact caused some X-Men fans to hate the character declaring that Sentinel is a machine for mutant genocide. Also a case of ComplainingAboutShowsYouDontWatch as this is kind of the point; showing that even a war machine like the Sentinels could become a force of good. That said pretty much everyone felt that [[spoiler: Emma [[MoralEventHorizon crossed the line]] by when she nearly murdered it]].
* EnsembleDarkhorse: Since joining the book as a background character in issue #21 Juston Seyfert seems to be rapidly becoming one. He even got a spotlight during the Avengers Vs. X-Men arc.
** Although they ARE main cast members Mettle and Hazmat are easily the most popular characters in the book. As such fans were ecstatic when they finally got together.
* FriendlyFandoms: There's big overlap in fandoms of Avengers Academy, YoungAvengers, [[NewMutants New X-Men]] and {{Runaways}}.
* FunnyAneurysmMoment: Hazmat - an ethnically-Japanese girl with radioactivity based powers who has been described as a "walking Chernobyl". Less than a year after she was introduced, the Sendai earthquake happened, which caused radioactive material to escape from the Fukushima nuclear powerplant.
* HarsherInHindsight: Hazmat, Mettle and Striker calling out their status as CListFodder in light of ComicBook/AvengersArena.
** [[spoiler: Juston and Sentinel's near-death experience at the hands of Emma Frost similarly becomes rather depressing given their fate in Arena.]]
* MoralEventHorizon: [[spoiler:Emma]] has one in the ''Avengers vs X-Men'' tie in [[spoiler:she scraps Juston Seyfert's [[RobotBuddy pet Sentinel]], simply for being a Sentinel]].
* MemeticMutation: Mettle, particularly his face, became a meme on a [[ImageBoards a particular image board]] and before his name was announced, they called him "Fortress". Acknowledged twice in the comic itself, once of Mettle learning of his meme status (making up for him being mistaken for the child of the Red Skull) and later when lamenting the attention, he declares that they betrayed him.
** During the flag football game Jocasta tries to keep order by using an in built taser to shock anyone who [[NecessaryRoughness starts brawling]], when Mettle is threatened with it he exclaims "Don't tase me, Jo!"
* MemeticSexGod: Mettle again.
* TheScrappy: White Tiger due to being a CanonImmigrant from a largely disliked cartoon and having a rather shallow personality that consists mainly of being a bitch and haranguing Reptil for not doing enough for the community as a Latino superhero.
* StrawmanHasAPoint: During the "War with the {{Runaways}}" arc, Hank Pym and Tigra plotted to take Molly Hayes and Klara Prast and put them into foster homes where they would never be found by their older "siblings". Predictably, when the Runaways found out, they attacked. While Pym and Tigra's plan sounded cold and heartless, and while Hank Pym is probably the last person who ought to be making decisions about other people's lives, it's worth noting that the arc was, in part, a follow-up to the unfinished "Home Schooling" arc from the Runaways series, the central thesis of which seemed to be that Nico and Chase were god-awful parental figures who seemed especially ill-equipped to help Klara, who was still showing signs of trauma from her near-death experience and who is powerful enough to accidentally kill someone if she gets too upset. Thankfully, at the end, [[spoiler:Nico casts a spell to make each team see things from the other team's point of view, and thus the two groups are able to reach a peaceful compromise.]]
* TheWoobie: Most of the cast, but Hazmat and Mettle in particular. Hazmat had her life and future ruined when her powers manifest in full, and she found out that some of the bad things in her life (sickness of parents, death of her dog) really were her fault. Now she's locked in a containment suit for pretty much the rest of her life so she doesn't kill anyone. Mettle's not much better off. It makes her very bitter, but deep down, she's very much a Woobie. Ever since he manifested his powers, poor he has shades of this. Looking like a monster thanks to his red metallic armor and having no skin as well as he was often mistaken as 'Red Skull's son' by the public. He is also qualified as the IronWoobie.
** Of all the instructors, it's Speedball. Though he is slowly recovering from his Penance phase, he still cuts himself behind closed doors as he claims that is the only way for him to use his more powerful, Penance-based powers in fights and he is haunted by the memories of Stamford disaster. This guy seriously needs a hug.
* UglyCute: Mettle
* UnfortunateImplications: Addressed within the comic. Some readers have a problem with [[spoiler: Striker's homosexuality, mainly due to the fact that he was molested by a man as a child. Striker himself is conflicted about this as well and is worried that [[RapeAndSwitch his molestation was what turned him gay]]. However after a talk with Julie, she tells him that ultimately his molester can only exert that power over him if he let him, which he does not.]]
