I'd recommend 'Solo Leveling.' The main character becomes extremely OP and has some morally ambiguous traits that make him an anti-hero. The action and story are top-notch.
Try 'Tokyo Ghoul'. Kaneki Ken undergoes a transformation and becomes a powerful yet conflicted anti-hero. The manga explores his struggles and choices.
I'd recommend 'Noblesse'. The MC has some traits that don't fit the typical hero mold, giving him an anti-hero edge. The story and art are both great.
I'd recommend 'My In-Laws Are Obsessed With Me'. The male protagonist is very strong and the romance aspect is sweet and addictive. It has beautiful art and a well-developed story.
You could try 'Return of the Mount Hua Sect'. The main character is reincarnated and gains amazing skills and abilities. The plot is quite engaging.
'Tower of God' is another great option. The main character grows in power throughout the story with a well-defined leveling system. The world-building and character development are top-notch.
In many light novels, anti - hero overpowered protagonists are used to explore different aspects of power, morality, and society. Their overpowered abilities can be a way to show the consequences of having too much power. For instance, they might struggle with how to use their power in a world that has different values from their own. This makes for a more engaging read as the reader gets to see the internal conflict within the protagonist, as well as their external battles. It also allows for unique relationships to form with other characters who may either fear or be attracted to their power.
Maybe it's to make the story more exciting and keep readers hooked. An OP MC can easily overcome challenges and show off cool skills.
Well, one could say it's the MC from 'The God of High School' - his powers are insane and seem almost limitless.
The main character might be overpowered because they have inherent supernatural powers that no one else possesses. Or perhaps they gain some ultimate weapon or technique that gives them a huge advantage. Also, sometimes their intelligence and strategic thinking make them seem unbeatable.
One such manhwa is 'The God of High School.' The MC is incredibly powerful and can take on any challenge.
