'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.
One such manhwa could be 'The God of High School'. It features a protagonist with exceptional powers and exciting battles.
In system manhwa, an overpowered main character usually has unlimited resources, progresses extremely fast, and faces challenges that are easily overcome. They might also have a special status or background that gives them an edge over others.
I'd recommend 'The Supreme Hero'. It has a unique system and an MC who's incredibly powerful.
One such manhwa is 'The Supreme Gamer'. It has a great storyline with a powerful MC and an engaging game system.
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.
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.
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.
