Damian Wayne revealed!

Pets

It's a well-known and acknowledged fact among the vigilantes of Gotham/ Batfamily that Damian adopts animals like Bruce does (stray) children. And yes, they have yet to find out if it is a hereditary disease, curse or something else - bets are placed and the pool is opened since Damian got his first pet.

And, like them -not that they want to further acknowledge it-, Damian's animals are very diverse. From normal household pets like cats and dogs to farm animals like a turkey and cow to a literal fantasy dragon bat!

Still, he's tamed them all, and they listen to him. Something Bruce can't argue for himself. To be fair, he's certain his kids are too chaotic for even Darkseid to handle them all at once (hence why Alfred is a god or similar).

Anyways, Damian's pets also knew who they should treat with respect unless he said so or hinted at whom he disliked.
This caused them to -at some point- develop the opinion that they should help those he works with, especially when they are in trouble.

Did he mention that he actually has even more animals?? Some that are even weider than a cow? He might've intentionally omitted that part to his family.

Instances of how Damian's pets cause headaches and came to the rescue:

-

The Young Justice and Justice League teams got trapped in another dimension; nothing new considering their occupational hazard. This is just a regular tuesday for them, pardon one exception. A giant -like skyscraper huge- black wolf with three pairs of eyes and chains was approaching them.

The beast recognizes Nightwing and Batman according to his masters one-sided talks and his smell lingering on them. His scent wafts off of them without a sour tang of his acidic (due to Lazarus contaminated) Blood. Friendly.

Controversially, the sentiment isn't shared as they don't recognize the large canine, (in part due to never having been introduced because he didn't fit into the Batcave) and thus a fight breaks out.

That is, until they see that he has a collar with the stylized R for Robin on it. Upon closer inspection by Superman, there was the name 'Nosyarg' in blood-red under it and a message on the back that said:

[Owned by the Son of Batman. Attack if you wish, but your spine and head will be mine.]

Tim stared at it blankly, doing his best impression of Alfred when he is done with this family, again.

"..."

Bruce felt a headache incoming.

Dick stared, now in a new light of circumstances, enraptured by the sight of the quite magnificent beast who somehow seems to be even more invulnerable than Clark.

"..."

"..."

"..."

"...that is one of Damian's pets isn't it?" He continued.

"Oh, definitely" Tim punctuated.

"But how even?"

"Does this mean the brat was here before??" Tim considered.
Dick gave him a scolding look for being rude and insulting their brother.

By now the others were not so subtly eavesdropping their not so quiet, nevermind private, conversation between two Batman-affiliated members.
