Plot armor

I have been watching a lot of movies and anime I have been seeing something they all have. Its this thing called plot armor its not in everything  but its still there to a degree. It's when the plot won't let the characters die, usually for the main character or important character is near death and then they
say that their friends are their power, or the say this isn't my final form. Its more of a thing in anime but its in comics to when the character would die the get resurrected. Now I won't say its bad if you have a main character you don't want them to die right away. But there are some points its not so good. Its a topic people throw around when they think a character should die but end up pulling something out of nowhere to finish the fight. But there are many way to get around it in some shows
there is no such thing as a safe character Akame Ga Kill anyone can die no matter what, Game of Thrones no one is safe in that world (according to what people have told me). There are ways to avoid plot armor I dont mind that its there as long as it doesn't draw way the crowd.
