Batfam neglected Reader but
the Reader stop/never search their approval.
(Bad English, not my first language)
I already talk about Harvey!Reader, so now I'll talk about others Reader ideas I have (and lyrics at the end ofc) :
A Reader that wanted approval from the batfam, that wanted their attention, but realize that they won't have it. Whatever they do, they won't be seen. And they decide to take it at their avantage.
They decide to become informants.
They will stay at a dark corner of the batcave, listening the Batfam during their missions, noting any information that might prove useful.
They don't notice the Reader, they never did.
They are like ghosts, listening everything everywhere, without being notice.
Informant!Reader here is calm, with a quiet rage that want to come out. They give informations to everyone, heroes like villains like vigilantes like civilians. Of course, there is a price. Sometimes it's money, sometimes dirty work (like killing someone).
They are dangerous because nobody knows how they have all these informations.
And the batfam will realize who they are only because one day Alfred decide to give a coffee to Reader in the Batcave. This or because the Reader is at the verge of death.
I can imagine Alfred just giving coffee or hot chocolate to the Reader in the batcave and nobody noticing it until like, 3 years after Reader decided to become an informator.
2. A Reader that hate to the max.
Listen to me, a Reader who hate Bruce and the Batfam so much because of their negligence that they become everything they hate.
They learn magic, become a villain, heck they'll even find a way to become a meta just because Batman hate them apparently.
The Reader know Bruce don't hate metas, even have a son that is a meta (Duke), but they still will find a way to become one just to see his face when he realized the monster he have created.
Watch this Reader becoming friend with the Joker, even if the Reader themselves hates him, they will still be friends just to anger the batfam.
And when they are in their civillian identity, the Reader decide to makes rumors about the batfam. 90% of the rumors about the Wayne were created by Hater!Reader.
3. A Reader who can see ghosts
Imagine a Reader that can see ghosts, and during all their childhood, they had ghosts to help them.
Yes, the Wayne family neglected them, but at least they had the ghosts. And the ghosts decide to protect them and to teach everything to the Reader. Yes, everything, even how to kill and hide a body.
The ghosts are this Reader family, and they will fight everyone who try to say otherwise.
The ghosts are all different, like I can see a military one teaching the Reader how to use guns, a chief one teaching them how to cook, a doctor and a nurse how to treat a wound, a child one playing with them and a dog ghost.... and more !
See Ghost!Reader having a big family of ghosts who can and will avenge them.
I can imagine the ghosts stealing/destroying some of the batfam stuffs everytime they neglect the Reader. Like for exemple Dick promised to play with them, but at the end he didn't because he forgot ? Watch all his technology stuff go BOOM.
4. A Reader who found comfort in the death
A Reader who died (maybe suicide, or killed by the Joker) and is somehow adopted by The Death.
I love the idea of The Death being a good and kind entity, who see a child who suffer too much, who never had a great life, and deciding to just adopt them.
They see these souls and decide to make them their crows, their little soul reapers.
And Soul Reaper!Reader make no exception.
They have to take the souls of dead people and guide them to their afterlife, their eternity.
But one day, someone decide to revive them. And nobody is happy about it.
The Reader want to die a second time to continue their little job as a soul reaper, but the batfam won't let them die a second time.
The Death is at that 🤏 to kill them, even if they don't have the right to kill mortals.
5. JJ!Reader
I'm pretty sure that we all know JJ!Tim, well, in this universe, it's JJ!Reader.
Just imagine the angst when Bruce realize that one of his kids became a mini Joker. Imagine the shame he would feel because that could have been avoided, because he didn't realized that one of his kids was missing until the moment where JJ!Reader reveal themselves.
Imagine Damian reaction, because his blood sibling is now his enemy.
6. A Chaotic!Reader
A Reader who decide to become chaotic. "If they don't see me when I'm calm, then they won't see me if I decide to cause chaos." Type mentality.
They won't use the doors, instead they will use the vents and windows to enter a room. They will commit crimes like arsons. They will ruin every Wayne gala.
I can see this Reader dying and coming back to life with the "Being resurected isn't my problem, it's YOUR problem" mentality. Their death and the fact that no one cared/realized that they were dead is probably their trigger, the thing that change that little calm person to this chaotic gremlin.
7. Fighter!Reader
A Reader that decide to participate in underground fights for money and attention. It's their way to express all their anger, they hate and love attention at the same time.
At first, they started because they wanted to show their family that they weren't weak, they wanted to be a Robin like their older brothers Dick and Jason, they wanted to be a vigilante like their dad; but the family never looked at them.
They saw Tim becoming Robin, they saw how he was loved by their siblings and father. They were envious.
So they decided to fight in underground fight, a way to express all their anger and winning money at the same time.
I can see this Reader refusing to use Bruce money (if he even give them money) because they don't want to depend on him and his money. They don't want anything to do with the Wayne anymore. So they win their own money and will move out of the mansion once they have found an apartment to moved in.
