Despite being among the most renowned isekai main characters today, Kirito is still considered lackluster compared to these characters
Sword Art Online is often regarded as a cornerstone of the isekai genre overall, though it remains contentious in terms of quality and content. The series' protagonist, Kirito, is framed as the 'black swordsman', consistently triumphing over formidable opponents in the visual game world. Additionally, he is the romantic partner of Asuna Yuuki. However, being built up with too many strengths seems to have rendered Kirito the dullest character in the series and unable to match up to other isekai protagonists.

10. Azusa Aizawa (I’ve Been Killing Slimes)
Some isekai main characters are constructed around the ideal of all-encompassing strength, akin to Kirito. Other isekai characters are more modest in their power and create their own distinctive mark in various ways. A prime example is the witch Azusa Aizawa, transported to the isekai realm after overworking herself to death.

Azusa is a formidable witch, yet she is renowned for her warm, compassionate, and relatively humorous personality. These traits endear her to viewers even when I'm Been Killing Slimes has forgettable content. She also befriends a demon lord and forms a diverse group of friends with various personalities.
9. Blank (No Game No Life)
Foster siblings Sora and Shiro, known as Blank, gained fame in the online gaming world, adopting this shared identity. This unity positions them as main characters in the isekai realm, always functioning as a cohesive duo.

Similar to Kirito, Blank is an isekai hero in video games, but they are better developed. Instead of arrogant swordsmanship, Blank excels as skilled and strategic gamers, fostering seamless teamwork. This creates a harmonious group dynamic.
8. Myne (Ascendance of A Bookworm)
Myne isn't your typical isekai heroine found in other anime. Once a teenage bookworm, a tragic accident transforms her into Myne. Despite her love for reading, in Myne's new world, literacy is a privilege reserved for the aristocracy. Undeterred, Myne is determined to change her world so that everyone can access books.

Now, Myne's mission is to use her intellect and creativity to write books. Despite the challenges, she doesn't falter. Her determination inspires audiences, narrating a compelling story of overcoming adversity to pursue her passion for literature.
7. Ainz Ooal Gown (Overlord)
Ainz Ooal Gown, the infamous skeletal anti-hero of the isekai world, possesses seemingly unfathomable power, yet remains anything but mundane. With a complex character and divergent motives, he captivates audiences, transcending the typical archetype of a formidable antagonist.

Ainz's appearance and might echo that of a villain, instilling a sense of dread in viewers. However, beneath the surface, he harbors a benevolent nature, creating a compelling dichotomy between outer facade and inner essence. Thus, audiences are drawn into his journey by the allure of his character.
6. Subaru Natsuki (Re: Zero)
The isekai hero Subaru Natsuki stands out as a distinctive figure within this genre, remembered by many audiences for his resilience. Surviving in a harsh world through wit and the ability to reverse time upon death, Subaru faces myriad challenges, even with the aid of Rem and Emilia.

In his previous life, Subaru was merely a NEET clad in athletic wear, but he has since embarked on an arduous journey of growth and heroism. His path to maturity far surpasses that of Kirito, imbued with deeper emotional complexity, unlike the somewhat lackluster romance between Kirito and Asuna.
