Danny moved to Gotham with his sister after their parents disowned Danny but decided to help him financially so he went to Gotham with his sister who was attending Gotham university.
He got into Gotham academy with a scholarship and after looking around the place decided not to be the same loser boy he was in Amity park. He wanted to be the chill dude that students would just nod at and continue with their day.
He decided to become friends with the Gotham academy nerds and losers and teach them many things. Such as to curse people in the most creative way possible. One example being Danny teaching them to insult someone by calling them ketchup pickle or something else to get them confused.
Eventually they stopped using curse words entirely deciding to express frustration through graphic descriptions of weird things. Danny was proud of himself for that
He talked to his classmates and he actually got along with them! The rogue attacks weren't as bad either. When scarecrow attacked he just simply snuck behind him and knocked him out with a bat he found.
Really he didn't understand how these guys were a threat.
On a more positive note he and Jazz sometimes went shopping on weekends and he started getting a glow up through the tips he learned online. Yeah life was chill the ghost attacks are being handled by Sam and Tucker well he's getting his life together and started getting good grades again!
Gotham academy was not prepared for the absolute wrecking ball that was Daniel Jackson Nightingale.
That is what the students of Gotham academy would say.
Daniel at first glance seemed like an ordinary boy who barely got into Gotham academy. Everyone expected him to run away at the end of the week except he didn't.
The first week he didn't even care he just walked around talked to everyone became friends with a nerds and was acing his classes. It's a second week that got interesting. All of a sudden the nerds who got bullied started standing up for themselves and insult people in unique ways.
One of the top students after getting scolded by the teacher again for not trying hard enough snapped and called her a caterpillar who would never know the sky as a radiant butterfly.
They started standing up for themselves and admittedly... Destroying the staff with their own rules and knowledge to the point of starting a rebellion when the teachers tried to retaliate. When the school board asked where they learned that from they just pointed at Danny who was sipping from his juice box while talking to some classmates.
Then a rogue attack happened. While everyone was screaming and running for their lives Daniel just took one look at the rogue snuck up on him and knocked him out and continued with his day like nothing happened.
He started making jokes about nothing beating Amity park to which students were progressively getting more concerned after even more rogue attacks one of them being led by the Joker only for them to be dismantled by Daniel.
At one point two rogues cried hugging Daniel as they poured out their life story. What does Daniel do? Fix their problems. Mr freezes wife gets cured. The Riddler has a TV show with people participating to solve riddles or escape rooms. No one knows how he did it.
He even started correcting teachers and even going out of school for a week to get proof that hes correct. Danny found a skeleton belonging to the empress of an empire that doesn't exist anymore. He even started talking about god's liking knew them personally. At this point it became a game to see how many things Daniel would uncover to prove his point.
Daniel dragged DAMIEN WAYNE to the cafeteria got him food shoved him some vegetarian milkshake got back to class patted his head and said don't be cranky anymore. He literally scruffed Damien and he went limp as he got him to sit with his friends. He looks like hes questioning his existence which to be fair they don't blame him for that.
But there's a few things for certain they are never going to the place called Amity park and Daniel is a deity reborn. Their own urban legend.
Meanwhile Damian is questioning what he feels to the random kid who just picked him up one day because he was scowling too hard and decided he's his friend now.
