Hot take..I feel like there's always a issue with making the villain too strong.

A lot of people complain about the Hero being too OP but I don't really see many others complaining about how OP/too strong you can make villains despite villains being too strong if as much ,if not a bigger problem,than the hero/protagonist being too OP.

People are like "oh you expect the villain to be a threat" and while I don't disagree, making them too strong could often lead to a incredibly unsatisfying defeat and the author writing themselves into a corner with defeating them when they themselves made said villain too strong for any satisfying way for them to be defeated and brought down.

You can make your villain strong but don't make them so strong to the point where you write yourselves into a corner with trying to bring them down and you either have to boost the protagonist and crew to really high levels in order for them to have a chance or you have to do some bullshit and make a even stronger villain late in the game to stop said strong villain.

I genuinely can't tell if making the villain too strong is just a severe lack of foresight and planning or what but it gets to a point where it's just annoying and it's even worse when said villain has insane amounts of plot armor protecting them from any Ls cause "protag has to defeat them."

I've noticed that issue really in Anime(like with Kaido,Sukuna,etc),but also in other series like with the Joker and such.
