There an au for DC X Do of Danny being a cat and Damian beloved pet
In your opinion how would the battam be if they realize that they have an eldrich horror as a pet in a shape of a cat?
Honestly? I'm surprised that no one has done the reveal that they had in the Captain Marvel movie in the avengers series.
The family is stuck in a dangerous situation as civilians with no way out unless they reveal their secret identities as vigilantes. In comes Danny, being held protectively by Damian. He opens his mouth, releasing a plethora of tentacles, grabbing a gun or something from the villain and eating it whole. Everyone is standing there, in shock, as this creature they assumed was a cat let's put a disgruntled burp and curls into Damian's chest. The villains decide that it isn't worth it, if there is a risk of being swallowed whole as well, and they take off. Leaving the bat family to grapple with the aftermath of having some sort of Eldritch monster (or alien, we don't know Bruce!) as Damian's beloved pet.
Damian, on the other hand, is quite pleased with this turn of events, and is wondering how hard it would be to teach Danny how to do that on command. Patrol would be much more entertaining.
