* EstablishingCharacterMoment: In his very first appearance, Asano explains that he wants to line up all the colors of the Rubix cube quickly. The answer? He simply jams a screwdriver in to take it apart and then put them back together. This moment shows that not only he's willing to use ''any'' method to win, but show how he's willing to brainwash his students to follow his dogmatic educational system.

* RuleOfSymbolism: As seen in his EstablishingCharacterMoment, Asano's "method" of solving the Rubix Cube shows his willingness to teach students to follow his brutal dogmatic educational system, by using ''any'' means necessary. Also, by using this tactic repeatedly, he ends up causing bad psychological damage to the same students he's trying to teach, to where it'll eventually fracture their minds, much like how the pieces of the Rubix Cube will eventually get damaged to the point where they can't fit back altogether.

* WorthyOpponent: While he holds most of 3E in absolute disdain for most of the series, the two members he outright admits to be worth his effort are [[JackOfAllTrades Isogai]] and [[TheRival Karma]].

* TokenGoodTeamate: Despite his initial SmugSuper attitude before his HeelFaceTurn, he had always been ''leagues'' better than the rest of the main campus students towards 3-E. At worst he's was a arrogant JerkWithAOfGold and that firmly stopped after his HeelFaceTurn.

* FatBastard: Tanaka.

* HeterosexualLifePartners: The hetero part is a bit doubtful; for some reason, [[http://www.mangareader.net/assassination-classroom/52/15 they are apparently closer]] than normal friends.

* LeanAndMean: Takada.
* NerdGlasses: Takada.

* NotSoDifferent: [[spoiler:When he first started as a teacher, Asano was an extreme optimist, very much like Koro-sensei. He only changed due to one of his students committing suicide.]]

* RealityEnsues: [[spoiler:After Koro-sensei's death, his school practices come under fire and he's eventually forced to both discontinue his system and resign as principal. Nagisa, however, figures that he was eventually expecting this.]]

* WouldHurtAChild: He beat the hell of the four exchange students, who still are technically fifteen-year-olds. Granted, this occurred during a four-on-one challenge that they could have backed out of. It was brutually one-sided, all right.
* WouldntHurtAChild: In most cases, he considers physically hurting students to be too "brutish" in his opinion to be acceptable. It is far preferable to instill fear through psychological tactics.

* PetTheDog: In chapter 160 [[spoiler: it's revealed he had a soft spot for the late Aguri Yukimura. He goes on to say that she had endless amounts of vitality and a great passion for education, and she would have been an outstanding educator in a few more years, had it not been for a [[TearJerker regrettable]] [[KilledOffForReal loss]].]]

* {{Hypocrite}}: [[spoiler:He was horrified by the fact one of his students committed suicide because his self-esteem was destroyed by being constantly bullied, only to develop a school structure that promotes students to bully and destroy other student's self-esteem.]]

* HonorBeforeReason: Refuses to compromise his beliefs or education method, even with the world at risk.

* SadistTeacher: It is known that he teaches classes. Even though he isn't a teacher of Class 3-E, he is a bastard to them.

* WellIntentionedExtremist: His system intends to ensures that the top 95% of the student body becomes highly successful... by treating the lower 5% like garbage.

* WouldHurtAChild: He beat the hell of the four exchange students, who still are technically fifteen-year-olds.
* WouldntHurtAChild: In most cases, he considers physically hurting students is too "brutish" in his opinion to be acceptable. It is far preferable to instill fear through psychological tactics.
* YouHaveOutlivedYourUsefulness: He fired Takaoka. His objection wasn't even with Takaoka's use of violence as a teaching method. While he disapproved of it, the reason he stepped in was that [[spoiler:Nagisa beat Takaoka in their fight,]] which meant the class would never be afraid of Takaoka again.

* PlotIrrelevantVillain: {{Downplayed|Trope}}. Asano Sr. does have his importance at serving as an antagonist to the Class-E students in the school life side of the story, but ultimately, he's unrelated to the situation with Koro-sensei blowing up the Earth and the connection with the true BigBad of the overall series. If anything, he only took advantage of the situation in order to gain more profits to spread his dogmatic educational system.

* TheSociopath: He has not even the slightest shred of remorse or empathy for the students whose lives he actively tries to ruin. He also has the superficial charm and manipulation ability aspects of the disorder down pat. {{Subverted|Trope}} because [[spoiler: Gakuho is capable of being kind and encouraging. However after learning Ikeda's suicide, Gakuho blamed himself for not instilling the right values in his student and resolved to never repeat that mistake. Until Korosensei calls him out for being ''too'' ruthless. Gakuho realises his mistake and decides to become a better person.]]
* SoreLoser: [[UpToEleven In the most extreme way possible]]. The best example is in chapter 123. [[spoiler:Class 3-A lost because they couldn't concentrate on the second half of the exam as they lost the bloodlust he whipped up on them. When his son chews out his class, he doesn't take it and slaps him when his classmates begin to respect Class 3-E's growth and even ask him to transfer them to Class 3-E if he's not happy. This also results everyone in Class 3-A leaving him.]]

* VillainousBreakdown: Suffers from an [[TranquilFury outwardly stoic]] one after [[spoiler:Class 3-E defeats Class 3-A in the second term exams, to the point that Class 3-A has students asking to be put into 3-E to learn from their teaching methods rather than his own. First, he slaps his son hard across the face in full view of the rest of the class, then he attempts to destroy the former's campus, kill Koro-sensei and place Class 3-E in what is essentially a prison.]] Gakushu realizes it, and points it out.

* VillainWithGoodPublicity: He's respected and liked by students and teachers from the main campus and has won several awards for his top-notch educational system. At the same time, he treats Class 3-E in a way that violates Japanese school regulations. He not only approves of Takaoka's violent punishment methods until they became ineffective, but he also [[spoiler:beats the hell out of the four exchange students,]] which is definitely illegal and criminal. [[spoiler:Then it all comes crashing down at the epilogue, after revelations of his more unsavory methods created a huge backlash that forced him to resign as principal.]]

* WorthyOpponent: [[spoiler:Comes to view Koro-Sensei as this, developing a level of respect for his teaching methods and complimenting a recently deceased Koro-sensei to Nagisa.]]

** Not even he agrees with Takaoka's sadistic TrainingFromHell methods, stating that while fear is an essential component of education, teachers that can only instill fear through violence are the worst kind, especially when it becomes counterproductive.

* PlotIrreleventVillain: {{Downplayed|Trope}}. Asano Sr. does have his importance at serving as an antagonist to the Class-E students in the school life side of the story, but ultimately, he's unrelated to the situation with Koro-sensei blowing up the Earth and the connection with the true BigBad of the overall series. If anything, he only took advantage of the situation in order to gain more profits to spread his dogmatic educational system.

* AmbiguousDisorder: As shown how extreme he is by proving his current education philosophy right after the death of one of his former students hints the severe emotional imbalances as a result of repressed grief and severe Post-Traumatic Stress Disorder. Also, he can be considered a bit odd prior to his past as a cram school teacher.

* AwesomenessByAnalysis: He became an InstantExpert by intently watching and analyzing a black belt karate instructor over three days, learning his techniques and weaknesses.

* BigBad: Of the school life side of the story. Every single problem Class 3-E faces originates with him.

* EvilCounterpart: [[spoiler:His backstory retroactively makes him one to Koro-sensei, which is made explicit in Chapter 126. He was originally an impossibly talented oddball teacher. Then after Ikeda's suicide he became an impossibly talented oddball SadistTeacher. Basically, he's what would happen if Koro-sensei went bad.]]

* InsaneTrollLogic: Asano Sr. is more interested in preserving his system than ''keeping Koro-sensei from destroying the world.''

* SignatureLaugh: Fufufu.

* DissonantSerenity: When speaking to Takaoka about why he failed to use fear to teach his class effectively, [[NightmareFuel there is imagery of a centipede crawling down Takaoka's throat]]. And Takaoka is a trained military soldier!

* ThePowerOfHate: Chapter 94 reveals that he believes this is a key part of learning from defeat. The feelings of hatred and humiliation stemming from a loss is what drives the losers to do better next time. The irony, however, is that that it goes both ways [[spoiler: and when E-Class does indeed do better then his studies, he can't really seem to take the loss. Koro-sensei reminds Asano what the latter used to be and Asano realises he too has gone too far.]]
* RealityEnsues: [[spoiler:After Koro-sensei's death, his school practices comes under fire and he's eventually forced to both discontinue his system and resign as principal. Nagisa, however, figures that he was eventually expecting this.]]

* RuleOfSymbolism: In his very first appearance, Asano explains that he wants to line up all the colors of the Rubix cube quickly. The answer? He simply jams a screwdriver in to take it apart and then put them back together. In two ways, this moment shows that not only he's willing to use ''any'' method to win, but it applies to how he's willing to brainwash his students to follow his dogmatic educational system and causing bad psychological damage to where it'll fracture their minds.

* VillainousBreakdown: Suffers from an [[TranquilFury outwardly stoic]] one after [[spoiler:Class 3-E defeats Class 3-A in the second term exams, to the point that Class 3-A has students asking to be put into 3-E to learn from their teaching methods rather than his own. First, he slaps his son hard across the face in full view of the rest of the class, then he attempts to destroy the former's campus, kill Koro-sensei and place Class 3-E in what is essentially a prison.]]
