What makes a reincarnation OP MC interesting in a light novel?

A best OP MC can also be defined by their relationships. In light novels like 'Re:Zero', Subaru has his Return by Death ability which is OP in a sense. But it's his relationships with the other characters, his love for Emilia, and his growth through his interactions that make him a great MC. The way an MC interacts with the world around them, whether it's a fantasy or sci - fi setting, and how they use their powers to either uphold or subvert the norms of that world also contribute to them being considered 'best' and 'OP'.

One popular character could be Subaru from 'Re:Zero'. He has an OP (overpowered) ability which is his Return by Death. It allows him to go back in time when he dies, which gives him a huge advantage in the dangerous world he's in.

One such light novel could be 'Sword Art Online'. The main character Kirito is extremely powerful and often overcomes difficult challenges with ease.

Well, first of all, a strong character arc for the MC. If the MC starts from being weak and gradually becomes OP in a believable way, it's really appealing. For example, in some novels, the MC has to endure hardships and learn from his experiences to gain power.

I'm not entirely sure as there could be many light novels with an OP (overpowered) main character (MC). It could be about a hero in a fantasy world who has extraordinary powers and uses them to overcome various challenges.

One characteristic is their unique abilities. For example, in 'Overlord', the MC has abilities that are far beyond normal characters in the game - turned - real - world setting. Another is their rapid growth or high starting level. In 'Sword Art Online', Kirito starts with a good level of skills which he further hones.

One factor that makes it excellent is the character growth, even if the Mc is OP from the start. Maybe they start as physically strong but lack emotional intelligence, and over time they develop in that aspect. Also, an engaging plot that challenges the OP Mc in different ways is crucial. If the Mc just breezes through everything without any real struggle, it gets boring. But if there are opponents or situations that make the Mc think and adapt, it's a great light novel.

One great light novel with a powerful main character (MC) is 'Overlord'. The MC, Ainz Ooal Gown, is extremely OP (overpowered). He starts as a max - level character in a game world that has suddenly become a reality. His abilities and strategic mind make him nearly unbeatable.

The light novel 'Akame ga Kill!' also has an OP female MC in Akame. She is a highly trained assassin with a powerful teigu (a special weapon). Her skills in combat and stealth are top - notch, allowing her to take on much stronger opponents.

The genre also often features elements of self - discovery for the MC. Despite being overpowered, they still need to figure out their place in this new world. They may face moral dilemmas, form relationships, and learn about the history and secrets of the isekai world. This combination of OP abilities and personal growth in a new and strange setting is what makes the 'op mc isekai light novel' genre so appealing to many readers.
