Batman has hundreds and more files on the Batcomputer on how to defeat or, God forbid, permanently take down every single hero and villain in existence on Earth.

Unfortunately, some of those files also include his family.

After all, the Batclan is one, if not the, most dangerous family of heroes existing on Earth: from the violence and brutality of Red Hood to the intelligence and tactical skills of Red Robin to the lethal fighting skills of Black Bat who ranks in the top 3 as one of the most dangerous people on the entire planet, etc.

Sometimes Bruce wonders if there is some alternate reality in which he and his family used their extraordinary abilities out of the ordinary for evil instead of good, if they had succeeded in conquering the Earth or something like that.

Bruce always decided that he did not really want to know the answer to his question.

So it is obvious that Bruce spent hours in front of the Batcomputer screen writing very detailed reports on how to incapacitate each member of the Bat Family, including Alfred Pennyworth.

Doing this was one of the hardest things Bruce has ever done in his entire life: his heart was in danger of ripping itself in two as he wrote in great detail about how to put down, even permanently, his family, his children, and his father figure in case they were to be mind-controlled, or worse, if they were ever to deliberately turn to the dark side.

However, there is one file that has been empty for years now and will most likely remain empty forever.

And that file is really about his firstborn.

As soon as Bruce had moved on to having to start filling out the contingency plan on Nightwing, to his horror he discovered that he did not even know where to start.

It was easy (more or less) to overcome the threat of a Nightwing under mind control, since it would limit the first Robin's abilities.

But in case Dick Grayson voluntarily decided to turn to the dark side?

Days passed and Bruce still had not written a sentence on that file. Days turned into months and months turned into years. Never a word was written on the file.

Bruce had put his head in his hands when he came to a conclusion that left him with bitterness in his mouth, and that is also an understatement.

Bruce knew for a fact that he alone would never be enough to be able to defeat a Nightwing with no morals, no matter how hard he would try.

The same argument can be made for the former Robin and Damian.

Dick had already proven himself to be the most brutal Robin: while he was under Joker's control as Dickyboy, he had taken down Jason and Tim simultaneously with impressive and frightening ease.

And this was merely mind control, let alone Dick ever turning to the dark side!

Bruce was sure that Dick would win in a one-on-four confrontation against the other former Robins as well: against Jason, Tim, Damian and Stephanie, all at the same time.

Dick was simply too much for them, even excluding the emotional factor.

Jason trained with Batman for a short time (the shortest of all) before he was killed and then with the League of Assassins, becoming much more brutal and dangerous.

Tim has trained with Batman, Nightwing, the Teen Titans, Lady Shiva, and Ra's, and while he is certainly dangerous and not to be underestimated, it is well known that Tim is more suited to investigative skills and being one of the greatest strategists (skills that Dick possesses at full capacity) rather than his fighting skills.

Damian was trained at a very young age by the League of Assassins for many years before coming under Dick's and then Bruce's training but, although he has great potential, he is still a child.

Dick, on the other hand, is a different story.

Not only did he train from the age of eight (the youngest of all) under Batman for almost a full decade (the longest of any protégé Bruce has ever had), but he received from the Dark Knight himself the toughest and most efficient training Bruce has ever given one of his other protégés.

Bruce knows he was one of the main reasons his son became the most dangerous weapon on the planet, far more so than Cassandra Cain ever could be.

And on top of that, Dick has trained frequently and regularly under Lady Shiva, Deathstroke The Terminator, the Court of Owls, the Justice League, the Titans and Teen Titans, and many others.

The trainings of the former Robins paled sharply in front of Dick's.

Not to mention that Dick is Batman's most experienced protégé and has been fighting crime far longer than the others, second only to Batman himself by a few years.

Dick has faced meta-humans, gods, demons, aliens, and more as if it were his bread and butter.

Dick has trained with meta-humans, gods, demons, aliens and much more as if it were his bread and butter.

Which is why, if Dick were ever to deliberately turn to the dark side and become unscrupulous, it would take Nightwing very little to bring down the entire Bat Family.

Batman would fall like a gnat.

Red Hood would fall like a gnat.

Red Robin would fall like a gnat.

Robin would fall like a gnat.

Spoiler would fall like a gnat.

Signal would fall like a gnat.

Batwoman would fall like a gnat.

Oracle would fall like a gnat.

Black Bat would fall like a gnat.

There is no shadow of a doubt that Cassandra is a better hand-to-hand fighter than Dick, but Nightwing surpasses her in speed, agility, physical strength, intelligence, as a strategist, experience, unpredictability ecc. and he is one of the very few people Cass will have a hard time reading him as Dick is also one of the best at reading the movement of bodies and the emotions of others and trick her.

Not to mention that Dick was the only Robin who was trained by Batman to know how to incapacitate each member of the Justice League, and Dick also trained with them frequently.

Dick is one of the best leaders, if not the best, in the entire world and represents the heart of the entire hero community.

The Justice League would fall like gnats.

The Titans and Teen Titans would drop like gnats.

The Outsiders would drop like gnats.

And not only this:

The League of Assassins would fall like gnats.

The Court of Owls would fall like gnats.

The Rogues of Gotham would fall like gnats.

Bruce almost vomited when he came to the conclusion that nothing and no one on Earth could ever stop a dark, unscrupulous, without moral Nightwing.

As Bruce Wayne, he was the best father Dick Grayson could have wished for after his parents died.

But like Batman, he was a tough mentor and one of the most effective the first Robin could have ever had.

And despite the gravity of the situation and what he had done to his firstborn, Bruce was still proud of his son and Dick would forever be his greatest accomplishment to him.

Bruce admitted that the entire planet was lucky not to know the darker side of Dick Grayson.

The universe would never have been ready to know it. Because the day Dick Grayson becomes evil, the universe will cease to exist.

Not because that day will never come.

But because Dick Grayson will make it come.

So, having said all that, it is a few but definitely significant words that fill the contingency plan on Nightwing in case the hero of Bludhaven ever turns to the dark side.

Let's hope that never happens.
