One popular one is 'Overlord'. The main character Momonga is extremely overpowered. He starts as a max - level player in a game and when the game world turns into a real one, his abilities are far beyond others. His magic powers and strategic mind make him nearly unbeatable.
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.
Some popular overpowered MC (main character) novels include 'Solo Leveling'. In this novel, the MC starts off weak but gradually becomes extremely powerful with unique abilities. Another one could be 'Overlord', where the MC is an incredibly strong character in a game - like world. And 'The Legendary Mechanic' also features a very overpowered MC with great skills and development in a sci - fi setting.
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.
The theme of leadership also appears frequently. In 'The Rising of the Shield Hero', Naofumi has to lead his small group of allies against much larger forces. His overpowered abilities give him the means to do so, but he also has to develop leadership skills. Also, there is often a theme of justice. These overpowered characters usually end up fighting for what they believe is right. They use their power to protect the weak or to right the wrongs in the world they inhabit, whether it's a virtual world like in 'Sword Art Online' or a more traditional fantasy world like in other novels.
One interesting aspect could be the unique power dynamics. With an overpowered main character as a minion, it flips the traditional hierarchy. It might lead to unexpected plot twists as the minion's power could disrupt the normal order of things in the story's world.
A really good overpowered MC isekai novel is 'The Rising of the Shield Hero'. Naofumi is initially treated unfairly but as he progresses, he becomes extremely powerful. His shield gives him unique abilities that set him apart from others in the isekai world. Then there's 'Log Horizon'. Shiroe, the main character, has a great intellect which, combined with his in - game skills, makes him overpowered in the world he's isekaied into. Also, 'Konosuba' has an interesting take on an overpowered MC. Kazuma has some unique abilities, and his party members also contribute to his overall 'overpowered' situation in the comical isekai world.
One popular overpowered mc light novel is 'Sword Art Online'. The main character, Kirito, is extremely overpowered in the virtual world of the game. He has incredible sword skills and the ability to adapt quickly to various situations, making him stand out among other players.
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.
One factor is the sense of wish - fulfillment. Readers like to imagine themselves in the shoes of a character who can easily overcome challenges. For example, in 'That Time I Got Reincarnated as a Slime', Rimuru's ability to gain new powers so effortlessly is exciting. Another aspect is the ability to change the world around them. An overpowered MC like Momonga in 'Overlord' can reshape the new isekai world according to his will, which is very appealing.
