Overpowered Main Character. i.e. OP MC in anime was, is, and always will be popular due to its endless entertaining value and the satisfaction the viewers get by seeing the protagonist beating the fish out of the cocky villains.
Saitama from One Punch Man pops instantly in your mind, right? But in this article, I am going to talk about OP MC in Isekai anime, so Saitama won’t be on the list.
That doesn’t mean there aren’t any other OP MCs as strong as Saitama. There are quite a few in isekai anime, which you may or may not know about.
