I didn't want to use the term "Deconstruction" because a lot of the time it is taking an aspect of their personality, abilities, mythos and exploring it more. Which can be good while leaving the original character intact. As well deconstructions can happen without even using the original character, for example Hyperion is a deconstruction (and Expy) of Superman.
And even deconstructions of characters are not always to dethrone them but to bring out their virtues. Batman has had plenty of fiction that explored exactly how obsessed he would have to be in order to be "The best at anything" a sort of insanity! that is also a deconstruction. They didn't do it by making Batman hunt down criminals and slaughter them because "Why would a vigilante keep criminals alive when they can bust out of jail?".
AS WELL there are plenty of deconstructions of characters who serve as a sort of satire of the criticism. "The Elite" are a deconstruction of Superman as a team of ultra-powerful antiheroes who believe in the worst in humanity and might makes right.
While in this specific case I mean taking a character and creating flaws, removing virtues, all in an attempt to ground them in some way. A "Destruction" so to speak, an airplane cannot fly without wings.
Gritty Reboots are not often deconstructions of the characters but their comic books. Captain America's movies are Gritty Reboots of the characters books while mostly leaving the character in tact. The same goes for Dark Knight movies for Batman.
While Man Of Steel is also a Gritty reboot... but completely changes the personality, ethos, and story of Superman.
Likewise Nancy Drew didn't get a Gritty Reboot. In her case the movie turned her into a Parody of "What you would think Nancy Drew is" rather then what her books currently are (or ever were... at least I can't think of the last time Nancy Drew stopped a criminal by baking them a cake). Hence why she acts like she is in "Leave it to Beaver", while also making her a loser to make her relatable... Even though those traits go completely against her in the books.

Man I am getting good at predicting destruction.
Was reading a wiki about this setting and apperantly there was this conglomerate of vast intelligence, power, and resources dedicated for the betterment of the universe (legitimately). I immediately said before reading on "Ok, it is doomed!"...
And yep... It was destroyed. In fact, it was destroyed FAST!
It seems to be a pattern that when fiction builds something up as good, and it isn't the main character, it might as well have a "Kill me please" sign on it.
