Overpowered characters in light novels can also be a drawback. They might make the story less suspenseful. If a character can solve every problem effortlessly, the tension in the plot decreases. However, in some cases, like in 'Overlord', the overpowered status of the main character is used to explore different power dynamics and how he rules in a new world, adding an interesting twist to the typical story formula.
They can drive the plot forward quickly. Since they are powerful, they can take on big challenges early on, like in 'No Game No Life', the siblings' overpowered intelligence allows them to enter high - stakes games right away.
Overpowered characters can also provide a sense of wish - fulfillment for readers. In 'Sword Art Online', Kirito's overpowered moments give readers the feeling of being able to overcome great odds. His abilities make him a hero - like figure, and his adventures, whether it's slaying powerful bosses or rescuing other players, are exciting and inspiring. This kind of character can keep readers engaged as they follow their journey through the challenges of the story world.
They often have unique abilities. For example, in 'The Irregular at Magic High School', Tatsuya has a special form of magic that is far more powerful than others. This sets them apart from normal characters.
Often, the protagonists have unique abilities. For example, in 'No Game No Life', Sora and Shiro have super - intelligent minds that give them an edge in every game they play. They can analyze complex situations quickly.
One popular overpowered light novel is 'Overlord'. In this story, the main character Momonga is extremely powerful in the virtual world of Yggdrasil and after the game's shutdown, he finds himself in a new and strange world where his overpowered abilities make him a dominant force. Another is 'That Time I Got Reincarnated as a Slime'. Rimuru Tempest starts off as a slime but quickly gains a variety of overpowered skills and abilities, evolving into a very powerful being in a world filled with different races and magic.
Another example is 'Overlord'. The protagonist, Momonga, is transferred into a game world and he has incredible powers right from the start. His character is designed to be extremely powerful, which makes for an interesting story as he navigates this new world with his overpowered abilities. In light novels like these, the overpowered protagonist often drives the plot forward by being able to take on challenges that normal characters couldn't.
One popular 'overpowered light novel' is 'Sword Art Online'. The main character, Kirito, has extremely high skills and abilities in the virtual world, which makes him overpowered compared to many other players. Another is 'Overlord', where the protagonist Momonga is transferred into a game world with his overpowered character build and abilities. And 'That Time I Got Reincarnated as a Slime' also features an overpowered protagonist, Rimuru, who gains numerous powerful abilities after being reincarnated.
Another aspect is prior knowledge or experience. In some light novels, the MC is reincarnated or transferred from another world. Like in 'Konosuba', Kazuma has knowledge from his previous life which he uses to his advantage in the new world, and this knowledge combined with his unique skills makes him overpowered in certain situations.
I'm not entirely sure as I haven't read the whole novel, but the most obvious main character would be the overpowered one in the minion role. There might also be a master or a group of characters that the minion has to interact with, like a powerful wizard or a noble who has the minion under their command.
