If you are an anime fan you will totally get what I am talking about. Every now and then we come across one or the other OP characters in the show and they are just jawdroppingly powerful, and believe me even your favorites might even hesitate to mess with them.
Here are a few of them:
1- All Might from My Hero Academia: This is the no. 1 hero from the My Hero Academia universe and is the symbol of peace for all the characters in the anime and this huge smile always on his face. His ability is One for All and is immensely overpowered. His persona seems to be derived from the western superhero stereotypes. His real name is Yagi Toshinori and is the main reason why the protagonist of the show Izuku Midoriya wanted to become a hero.
2- Madara Uchiha from Naruto Shippuden : This is the most badass character I've ever seen in an anime who can overpower anyone in his way. Originally the legendary leader of the Uchiha Clan who founded the leaf village along with his rival Hashirama Senju (aka The first Hokage).
The moment of his entry marked the onesidedness of the Fourth Great Ninja War and he took down all the five Kage's alone without using his full potential. Here is one of the videos you must see.
3- Lord Escanor The Sin of Pride from Nanatsu no Taizai: Now this is the way a proud warrior is supposed to be and he has one of the greatest entries in the history of anime. He is one of the members of The Seven Deadly Sins. He wields a one handed battle axe which has the ability to collect all the heat from Escanor and release at once. As the sun rises the power of this character increases and is at peak when sun is on the top and he himself becomes the reincarnation of power. Better watch out for this character when in the battlegrounds. XD Sun for All.
4- Saitama from One Punch Man: Now this one of the most comical characters you will find who is a hero for fun. XD
Saitama also known as the One Punch Man is the strongest character in the anime and no matter who the opponent is he always takes him down no matter what, even if the opponent is the Destroyer of World. The anime has one of the greatest mix of his comedy and is funny because of how insanely powerful he is. All it would take is one punch hence his hero name at the Hero Association.
Let me know what character do you think is the most OP and give an upvote for the post if you liked it!
