Often, there is also a sense of the protagonist being an outsider who has to navigate this new world. They might face initial distrust from the natives but gradually prove themselves. In terms of power, there are often power - leveling or power - up sequences where the protagonist gets even stronger over time. For instance, in 'The Rising of the Shield Hero', the main character starts with a somewhat limited power but gradually becomes very powerful through his own efforts and new abilities he acquires.
One popular overpowered isekai novel is 'Overlord'. In this story, the main character is transported into a game world and he has extremely powerful abilities right from the start. He has an entire guild of powerful minions under his control, which gives him a huge advantage in the new world.
One common element is Naruto having new and extremely powerful jutsu. For example, he might have a super - strong fire - based jutsu that can destroy entire villages in one go. Another element could be that he has enhanced physical abilities like super speed and strength that make him almost invincible in combat. Also, he may have a special connection to some sort of ancient or powerful entity that gives him an edge over everyone else.
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.
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 common element is that Harry often has enhanced magical abilities. This could be in the form of being able to perform advanced spells with ease or having a larger magical reserve. For example, in some fanfics, he can cast spells without a wand or can create entirely new spells.
Another theme is the battle against powerful foes. With an overpowered sword, the protagonist is usually faced with enemies that are equally strong or even stronger. This creates exciting battle scenes. In 'Sword Art Online', the battles in the virtual world with the help of the sword are a big part of the story.
One common element is the combination of different power systems. For example, if it's a crossover with a superhero universe, Harry might gain super strength or the ability to fly on top of his magic. This instantly makes him overpowered. Another element is that the author often gives Harry more knowledge or a different way of thinking. In some fics, he might be a genius in magic theory, allowing him to create new spells or use existing ones in ways no one else can.
Power and growth are common themes. The protagonist usually starts with a normal or weak sword - related ability and then gradually becomes overpowered through training, battles, or special encounters. Another theme is the mystery behind the sword. It could be an ancient weapon with a hidden power or a cursed sword that gives great strength but at a cost.
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 common element is the gamer system. Usually, the self - insert character has some sort of in - built system that works like a game, allowing them to gain levels, skills, and rewards. Another is the use of game knowledge. They apply things like game strategies, character builds, and combat mechanics to the Naruto world. For example, they might know how to optimize their chakra usage like in a game's mana management.
