Osborn Cobblepot

Osborn Cobblepot is Arkham Knight, a anti...hero? His morals are pretty murky. Either way his main interest is ridding Gotham of the Arkham Asylum. He was one of Bruce Wayne' s childhood friends.

History
His parents were important backers of Arkham Asylum and of the Arkham family. They also were minor landowners and had ties to the far more wealthy Cobblepots. Osborn was close friends with Bruce Wayne, Thomas Elloit, and Roman Sionis though he later realized Roman hated the rest of them.

It was a little before Bruce’s parents were murdered that his dad was killed due to a collaboration of the Arkham Family, the Falcones, and Mayor Hill. and only two months later his mother went missing after leaving for dinner with a friend, said friend never turning up. In truth she also was killed as part of the cover up.

He got sent to Britain to live with his mother’s relatives as that was what she put in the will knowing that her sister in law was starting to lose grip on things and already had enough to worry about.

As he grew up he had behavioral issues and as a teen and young adult even joined fight clubs where he improved his fighting skills. After that as a young man he also joined the army. He did get dishonorably discharged after he broke his superior officers nose.

That was about when he decided fuck the law, im gonna do crime. He set up some small crime enterprises and made a decent amount off of it, enough to get around to what he actually wanted to be doing. Finding out the truth of what happened to his parents.

So he packed up and headed off to Gotham where he then bothered Bruce Wayne, got in three fights with his cousin because he was trying to use the same name for a while since he had no better ideas and then bought out a small bar and hired the Riddler to help him figure out what happened.

Once he found out that the Arkham family had been behind it he took up the name Arkham Knight and started fighting the streets of the city, unfortunately he also does crime enterprise stuff on the side and considers the bat family to be part of the conspiracy controlling the city.

Trivia

 * He figured out Batman's identity but for the stake of both not coming off as more crazy along with keeping it a fair fight he has sworn to himself not to tell anyone.
