Natsuki Hashiba, Tomoya Matsunaga, Keiichi Katakura, Tsuyoshi Naoe want what most high school boys want to find: love. Unfortunately, when Natsuki is dumped on Christmas Eve, he finds himself feeling the exact opposite. Of course, his feelings of sadness quickly evaporate when Anna Kobayakawa, a girl from his school, comforts him during his tearful breakdown. Natsuki’s fallen in love all over again and he won’t let anyone get in his way, including his friends.

Mari Tsutsui is the perfect start to this list because she perfectly encapsulates some of the stuff we mentioned earlier. She is aggressive in a violent and rude manner to other people, indifferent to their presence, and arrogant in her comfort in being alone. Her aggressiveness especially comes out towards men due to a history of being teased and bullied and the resentment she feels for her older brother after he left her to get married. That aggressive and arrogant behavior stems from her lonely past and has made of her a loner for most of her life.

Saiki K’s powers have made his life somewhat dull (everything is predictable) while simultaneously attracting the weirdest people to him and therefore rendering his life senselessly challenging. He’s desperate for a simpler life without his powers where he can, at once, not deal with as much trouble but also have more reasonable surprises. Unfortunately, every day that passes by seems to drag stranger and stranger crowds, pushing him further away from his idealized life.

Shun Kaido is a Chuunibyou and believes that he is a hero combating an evil and mysterious organization called Dark Reunion. His delusions have led to him believing he is much greater and more powerful than anyone around him, and he proudly boasts about it to everyone that will hear him. Deep down, Shun is completely powerless, a coward, and can pretty easily be cowed by any sort of genuine opposition. As with many on this list, his aggressive and arrogant behavior is only there to hide an insecure and lonely interior.

Shouya Ishida, a class clown, spent a lot of his elementary school leading his class in bullying a deaf girl by the name of Shouko Nishimiya. When the girl succumbs to the pressure and transfers schools, Shouya takes the brunt of the blame and becomes alienated and bullied up until high school. Now suffering from social anxieties due to years of being isolated and ostracized, Shouya desperately desires to make good on the mistakes of his youth and that starts with trying to earn forgiveness from Shouko.

Naoka Ueno was one of Shouko’s principal bullies in elementary school and the only character who shows very little regret for her behavior during that time. Now in high school, she’s even more venomous towards Shouko for having caused trouble for Shouya in transferring schools. Her blunt and straightforward behavior leads to her demeaning and berating Shouko every chance she gets, and even attacking her at some point. Unlike most of the other characters here, she doesn’t show a lot of remorse about her actions.

In an orphanage where children are raised with love, care, and a tremendous education, there’s little reason to think life is anything but idyllic. One day, when Emma and Norman, two of the oldest children, discover that one of the last children to be adopted has forgotten her stuffed bunny, they set out to return it. Tragically, what they discover upon arriving at the gate is the young girl lying lifeless in the back of a truck.

Sister Krone joins the orphanage to help Isabella manage the possibility of an escape by some of the brightest children. Krone has ulterior motives: she wants to become a Mom and manage her own house, and she will sabotage Isabella to do it. Krone is the opposite of Isabella, she’s aggressive in her pursuit of success and confident of outwitting both Isabella and the children no matter what it takes. Of course, considering Krone was raised under the knowledge that monsters could devour her at any instant, it’s no surprise she became mentally shattered.

The last remnants of humanity hide behind walls as monstrous creatures called titans eat any human that roams within reach. Having seen his mother eaten by a titan during a breach in one of the furthermost walls, Eren Yeager harbors an unmatched hatred for the mindless monsters. He vows to join the Survey Corps, a military unit that ventures outside the walls to learn the means of eradicating the titan, so he can wipe them all from the face of the Earth.

Eren’s arrogance and aggressiveness are fueled entirely by his desire to avenge the death of his mother. It helps that he has also gained the power of a titan and can become a nearly unstoppable force in his quest for titan annihilation. In truth, it takes a measure of arrogance to believe that you can take down not just one but all the towering titans and Eren’s stubbornness in his quest makes this a boon even if it sometimes leads him into troubling situations.

In a world where superheroes, supervillains, and monsters run amok unhindered by society’s rules, mass destruction and death await at every corner. Even so, all of this is completely unimpressive to Saitama, a hero whose intense but simple training has led him to become the world’s strongest hero, easily capable of defeating any villain with a singular punch. Alas, when all of his problems are solved in such a swift fashion, life can quickly become dull for the hero known as One Punch Man.

Speed-o’-Sound Sonic should have been humbled when he was beaten effortlessly by Saitama, but he wasn’t, he vowed to train himself in order to one day defeat the incredible hero. Above all else, Sonic is an aggressive individual and this behavior is especially heightened when he is met with someone like Saitama who is extremely strong. He loves a good fight and defeat will only persuade him to work harder. Even having lost to Saitama, though, Sonic remains a supremely confident human who believes himself to be above anyone he meets, especially heroes. Sonic can probably lose a million times to Saitama, but his aggressive and arrogant attitude won’t stop him from coming back for more.

Shouyou Hinata forms a middle school volleyball team after being inspired by a similarly short but incredible volleyball played called the “Little Giant”. Tobio Kageyama is the star player of his own middle school volleyball team and is a widely renowned prodigy of the sport. Both of their middle school careers end tragically due to Hinata’s inexperience and Kageyama’s controlling behavior. Now in high school, they find themselves trying out for the same volleyball team and having to help prop each other up and round out their weaknesses.

The entire premise of Kageyama’s character is that he suffered in middle school because he was arrogant and aggressive. He bossed around his entire team even if he was partially to blame for his inability to match their capabilities. His behavior earned him the ironic nickname of “King of the Court” which was less an indication of his prowess and more of his behavior. Entering high school, his arrogant and aggressive behavior won’t work, and he’ll have to learn to behave appropriately with his new classmates if he wants to take advantage of his talent.

Jonathan Joestar has a luxurious upbringing thanks to his father, an English nobleman named George Joestar; however, when Dio Brando, the son of a man who once saved George, is adopted into the house after his father’s death, everything changes. Despite the front Dio puts up, he’s eager for greater status and power and will step on everyone, including Jonathan and George, to get it. A rivalry fueled by greed will grow bloody when supernatural elements grant Jonathan and Dio powers.

Joseph Joestar, the grandson of Jonathan Joestar, is loudmouthed, confident, and strong-willed. Of all the JoJos, Joseph must be the most arrogant and aggressive of a family of similarly arrogant and aggressive people. Joseph is the sort of person to shoot first and ask questions later. By the time we first see him in the show, he’s a man who has been arrested countless times for starting far too many brawls and being snotty around authority figures. Unlike a lot of characters on this list, this is simply how Joseph is and no one ever tries to reproach him or show him a different way to behave.

Hollows are corrupt spirits that prey on human souls, and Soul Reapers have the task of slaying them. Rukia Kukichi fails to complete her task when she’s hurt protecting a high school boy named Ichigo Kurosaki and his family. To save them from a brutal death, Rukia gives Ichigo her powers. As a Soul Reaper, Ichigo must now take on Rukia’s responsibilities and protect his town from hollows while she recovers from her injuries.

Grimmjow Jaegerjaquez shares a common trait with a lot of other people on this list, a disdain for authority. Among the Espada, he was always confident that he could take down anyone, including those of higher status than him. Grimmjow has little respect for law and order and a bloodlust for chaos and a good fight. His aggressiveness really becomes apparent in a fight, where his vicious and brutal tendencies show up. His entire demeanor is best exemplified by his endless punching session of Ichigo during their first meeting.

Izuku Midoriya is one of the unlucky few that don’t have a Quirk, a superpower that now appears in most humans. This is especially tragic because Izuku has dreamed of becoming a superhero for almost as long as he can remember. Even without a quirk, Izuku is determined to fulfill his dream of becoming a hero and studies intensively for the day when he can test for U.A. High, the top academy for prospective heroes. One day, when he comes to the rescue of an endangered classmate despite being powerless, Izuku inspires All Might, the #1 hero, to pass on his powers to him.

Katsuki Bakugo is arrogant and aggressive to the point of being completely unlikable in My Hero Academia. Ever since he discovered his powers, Bakugo has been revered as the star of his group of friends and eventually, the star of his classmates due to his naturally powerful abilities. He was constantly praised by everyone around him and that gave him somewhat of a superiority complex. His arrogance and aggressive attitude led him to be a school bully to the point of telling Midoriya to commit suicide. Unfortunately for Bakugo, when he eventually reaches U.A. High, he discovers that no one wants to be around someone who behaves like that and in turn becomes an isolated loner himself, though that does little to stop him from being aggressive and loud towards everyone else, including Midoriya.
