manga where mc starts off weak and becomes op

One such light novel could be 'Sword Art Online'. The main character Kirito is extremely powerful and often overcomes difficult challenges with ease.

Many anime works had plots where the main character started off as trash and then became stronger and stronger, such as Naruto in Naruto, Monchi D. Luffy in One Piece, and so on. These protagonists were initially considered useless or weak, but as the plot developed, they gradually became stronger and became heroes in everyone's eyes. This kind of plot could often attract the interest of the audience and at the same time, it could also create a growth process for the protagonist to increase the audience's sense of immersion.

Naruto Uzumaki, the male lead in Naruto, was such a character. Naruto Uzumaki was born in an ordinary family. When he was young, he was very weak and often bullied by other children. However, he had a strong will and an indomitable spirit. Through continuous hard work and training, he gradually became a powerful ninja. When he met a strong opponent, he would challenge them unyieldingly and gain growth and strength from them. In the end, he became one of the top ninjas in the Naruto world, proving that only through hard work and struggle can one become truly powerful.

The harem aspect means there are multiple female characters who are attracted to the MC. In these manga, the relationships can range from simple admiration to deeper emotional bonds. The female characters often have diverse personalities and abilities, adding to the complexity of the story. For instance, in 'Death March to the Parallel World Rhapsody', the harem members include a princess, an elf, etc.

Well, there are many. One example could be 'The Rising of the Shield Hero'. The MC in that starts off pretty weak but grows stronger over time.

The MC could become a penguin by accidentally entering a forbidden area or getting involved with绁炵 powers. Challenges? Well, there could be problems like not being able to move fast on land or struggling to fit in with the penguin community.

I recommend the following novels to you: 1. "I Have Countless Protagonists 'Guardian Spirits": The protagonist can summon the main characters in dramas, movies, and ACGN works to become his guardian spirit and become invincible. 2. "The Strongest Mage Emperor and the Weakest Unlucky Knight": The protagonist is the weakest knight, but no matter what happens, he will be safe and sound. It is a novel that is very suitable for readers with a fragile heart. I also recommend other novels that are invincible, such as "Gnolls Can't Practice Martial Arts","The Mad Son-in-Law of the City", and so on. I hope you like my recommendation. Muah ~
