Isekai Anime with OP MC When done right (for example, there’s a world-building and stuff), Main Character can be one of the most entertaining shows I watch. It’s so fun to see the Main Character not have to work hard and beat the crap out of those scumbags. I don’t mind fanservice, but not too much of it, and I’m not too fond of stupid perverted MC.

So I guess that makes them worth watching: the entertainment and the chance to escape from real life by imagining yourself as a Demon Lord who takes over the world. Not everyone thinks that way, but some do.
So yeah, isekai plus OP MC plus good execution equals entertainment. At least for me.
And “unmemorable” really depends on the person because Rimuru Tempest, Ainz Oal Gown, and Anos Voldigoad will always be in my head. I can’t think of a way to call these three main characters trashy. They are really cool and fun to watch in anime.
A trashy isekai anime with an overpowered main character would be, uh… For most people, I guess it would be that guy in another world with a smartphone. But I also kind of like it.
With that being said, here are some good isekai anime with Overpowered Main Character.
That time I got reincarnated as a slime/ Tensei Shitara Slime Datta Ken
Satoru Mikami, 37, is a typical office worker who is happy with his boring life in Tokyo, except that he has never had a girlfriend. In the middle of a casual conversation with his coworker, he is attacked by a stranger on the street and stabbed. But as he dies from his wounds, a strange voice keeps repeating itself in his head, giving him a bunch of orders that he can’t understand.

When Satoru wakes up, he finds that he has been reborn as a glob of slime in a world he doesn’t know. By doing this, he learns new skills, like the ability to eat anything and copy its look and abilities. Then, he finds the sealed “Storm Dragon” Veldora; a Catastrophe-level monster locked away for 300 years because it burned down a town. Satoru befriends him because he feels sorry for him and promises to help him break the seal. In exchange, Veldora gives him the name Rimuru Tempest to protect him from other beings.
Now that Rimuru is free from the boring parts of his old life, he starts a new journey with a clear goal in mind. As he gets used to his new body, his gooey actions spread out into the world and slowly change his future.
So I’m A Spider, So What!
The day at high school is as normal as it can be. The students go about their normal activities without any trouble, but then a disaster that has never happened before strikes the school and kills everyone in its path. Some students are lucky enough to be reborn in another world as nobles, princes, and other people with important backgrounds. This seems to be the result of a miracle.

But one girl is not so lucky. As soon as she is reborn as the weakest kind of spider, she feels the pain of her bad situation. Still, she has to keep going if she wants to survive the many threats to her life. When she finds out that her new world works like a role-playing game (RPG), she does her best to catch prey and kill monsters to level up and progress. As she gets stronger, she hopes that one day her hard work will pay off and give her a better life.
Overlord

The popular virtual reality game Yggdrasil is about to end in an hour. But Momonga, a powerful wizard and leader of the dark guild Ainz Ooal Gown, decides to stay in the game until the servers shut down. To his surprise, Momonga is still obviously conscious of his character, even though the clock has struck midnight. What’s more, the non-player characters seem to have developed their own personalities!
When Momonga sees this strange happening, he tells his loyal servants to help him investigate and take control of this new world. He wants to find out what’s happening and if other people are in the same situation.
The Rising Of Shield Hero
It’s about a normal guy, who gets isekaied along with the other three heroes. He receives the lame shield as his weapon, but others get cool weapons like a sword and bow. Everyone in the isekai kingdom sees him as a lame and weak hero. So he gets a lot of hate, and the kingdom’s royal family frames him.

However, as time passes, he becomes stronger and proves his innocence. I tried to make somehow it spoiler free as much as possible.
I would call this anime an “Isekai OP MC with a purpose.”
Have you ever noticed how simple a lot of Isekai anime are? Tensei Slime is a good show, but like a lot of other Isekai, the characters don’t have much depth.
It’s more for fun than anything else.
The Rising Of Shield Hero is not like anything else. There’s a reason to “connect” with the main character and even the other characters who are around him.
It has a good mix of fun, excitement, battles, and deeper meaning. And now here are some Chinese isekai anime with OP MC.
Quanzhi Fashi
Mo Fan, an aloof high school student, has found himself in a world that is similar to his own but also very different. In this world, magic has replaced the essence of science.

Mo Fan is still the son of a poor worker and the older stepbrother of a crippled sister, just like he was in his past life. Even though he has a lot going against him, he hopes to go to magic school and become a magician, a highly respected and lucrative job, so he can pay his father back for all his hard work.
Mo Fan gets into a well-known school of magic. But people talked about how poor he was and how he couldn’t do magic, making him the school’s laughing stock. Still, Mo Fan is able to use both the powerful fire element and the rare lightning element! Now that the versatile mage has two skills, what dangerous situations will they face?
