Transformers: The Bat Princess and the Cyber Bees

[Transformers + DC, American superhero crossover, Bumblebee pairing, human and machine, slight all-ships, many original settings]

As the only daughter of a certain Dark Knight and Gotham's little princess, Nova can easily get anything she wants.

Money? Is there anyone richer than Wayne Enterprises?

Power? Come on, her dad is Batman!

For Miss Nova, there's no problem money can't solve. And if there is, it just means she doesn't have enough money. The one thing she has plenty of is money.

Until she buys a pair of broken glasses to help a classmate with his car-buying plans.

Then everything changes completely.

Bumblebee's mission is to protect the glasses' owner until the leader reaches Earth.

As he waits at a used-car dealership to be bought by Sam, the human girl named Nova smiles at him.

From then on, that smile becomes a trace he can never erase from his neural processor.

Nova once asked him, “Bumblebee, do you like me?”

Bumblebee doesn't answer. He only feels his spark beating strangely.

By the time he finally understands his feelings, it's already too late.

“I once had a star, before she went dark.”

Notes (content warnings):

1. At first, the heroine doesn't know her dad is Batman. Her “mother” is Superman, created using the Kryptonian Codex, and has some connection to Primus.

2. This is a slow-burn story. The characters need to grow, and things won't always go their way.

3. Secondary couples: SuperBat, Optimus Prime/Ironhide. I haven't thought of any others yet; I'll add them if I do.
