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'.

'The Beginning After The End' is also a top - notch OP MC novel. Arthur Leywin is reincarnated into a world with magic and he has an innate talent that allows him to quickly rise in power.

They usually have a strong sense of justice or a unique goal. Take Luffy from 'One Piece' (which also has light novel adaptations).
