As with any well-written character, not everyone will like them at first. For example, they may go from villain to hero, or from immature to mature.\n\nHeroic and courageous personalities populate the realm of shonen anime heroes. In fact, this isn't necessarily how they begin. It has become increasingly difficult for shonen series authors to come up with unique characters for their leads and the entire cast of the anime.\nA villain introduction might be in order, or perhaps the character has too much self-confidence and needs to be humiliated. This is what happens when a character is well-created and the creator knows exactly what's holding them from achieving their peak popularity.\n1. Senku Ishigami (Dr. Stone)\nTo understand what had happened in the world, Dr. Stone’s Senku Ishigami had to remain bound in stone for 3000 years without losing consciousness, and he was the only person who could do it. It was tough to connect with him because he solely cared about research, and he could've easily been a villain in a different manga. As much as he cared about the science people develop, Senku was willing to do anything to protect his closest friends Taiju and Yuzuriha and put an end to the Stone Wars without a single life being lost.\n\n2. Vegeta (Dragon Ball)\nThe first time Dragon Ball’s Vegeta appears, he's a terrifying force. Only because he couldn't bear to be associated with saving the world does he blow it up after rescuing it. Goku, on the other hand, humbles him and sends him to Namek with a mission: to take out most of Frieza's troops. Vegeta's brash personality softens when he joins Krillin and Gohan in combat. While he can't quite match Goku in terms of power, his demeanor lends an interesting dynamic and flair to the cast as a whole.\n\n3. Medaka (Medaka Box)\nOne of the main characters in Medaka Box was considered unlikable because of her combination of so many shonen protagonist flaws at the same time, Medaka Kurokami. Everything appeared to go her way, and she did things without thinking about the consequences for the people around her. Medaka, on the other hand, became a more likable protagonist when it became clear that the series was satirizing cliches.\n\n4. Asakura Yoh (Shaman King)\nAs a character, Yoh is a laid-back guy who spends most of his time having fun. His only purpose in life is to relax, and he doesn't put forth any effort to achieve it. But finally, the novel focuses on what it means to be the Shaman King, and how someone with a tremendous desire to change the world would be the worst conceivable winner. This, combined with Yoh's determination to stand up for his comrades even in the most perilous circumstances, made the character entertaining to watch and follow.\n\n5. Hiei (Yu Yu Hakusho)\nHiei is a very different guy when he initially appears in the series. As a one-off antagonist, his initial purpose was to thwart Yusuke as he endeavored to collect all three of the Spirit World treasures. After his return at the end of the Spirit Detective Saga, he transforms into the beloved figure we know and love today.\nThis is where Hiei becomes the coolest hero of the '90s: a sharp-tongued swordsman. When it comes to dealings with the rest of the gang, his humor and his unwillingness to show favoritism toward Kuwabara, Yamada, or Yusuke keep things interesting.\n\n6. Asta (Black Clover)\nAsta is a little slow to warm up to, but she's worth the wait. It's not long before he's just another Naruto or Luffy, proclaiming to the world that he's going to achieve this unattainable objective while everyone else laughs at him. Black Clover’s Asta, on the other hand, is granted a special magic book and a sword that can negate any magic spell hurled at it because of his willpower. At this point, Asta quickly starts utilizing his own strengths—got he's the muscle and the will to defeat the Black Bulls' enemies with equal measure. He's now on the verge of succeeding his more gifted boyhood friend, Yuno, as the next Wizard King.\n\n7. Alibaba (Magi: The Kingdom Of Magic)\nAlibaba is an unlikable lead character up until he meets Aladdin. Although he's self-centered, he's also fearful. Though he has plans to restore his country, he's reluctant to leave his position as a clerk for a wealthy merchant. When Aladdin takes him into a dungeon and he emerges with a weapon, he begins to take more risks and put his swordsmanship training to use. While he's still an inexperienced and unreliable leader, by the end of the second season of Magi, he's capable and trustworthy.\n\n8. Laxus (Fairy Tail)\nIn his first appearance as a villain, Laxus targets the Fairy Tail guild, seeking to purge it of what he views as "weak" members in order to restore Magnolia's top guild rank once more. Natsu's Lightning Fire Dragon Slayer powers ultimately brought him down, making it all the more enjoyable to see.\nFortunately, when Laxus reappears much later, he's understood what Fairy Tail is actually about as a guild, and he saves the team from Hades. His dedication to the guild grows stronger, and he eventually fights for their honor alongside the other members.\n\n9. Todoroki Shoto (My Hero Academia)\nWhen you first meet MHA’s Shoto Todoroki, he can come across as a bit frigid. Distant and uninterested in making many acquaintances, he appears to be. It's only when his character has evolved that we realize why it took him so long to form any kind of friendship. A hero who could outshine All Might was instilled in him as the son of Endeavor.\nDespite this, Shoto's hesitation to use everything his father granted him, including his fire skills, cost him during his fight in the U.A. Sports Festival tournament arc. Shoto's narrative is more interesting than Deku's because he is following in his father's footsteps, but he is doing it for his own reasons, rather than to please his father.\n\n10. Gaara (Naruto)\nAt least for those who enjoy savages, Gaara could have been likable in his early episodes. During the Chunin Exams, he had no issue killing people and was the tournament's last boss, with everyone wondering who might defeat him. Ultimately, it was Naruto's understanding of Gaara's pain as a Tailed Beast inside of him that allowed him to break through to Gaara's humanity. As a result of this, Gaara began to reach out to other members of the Hidden Sand, mastering his skills, until he became the Kazekage of his village.
