Thank you, @silver-athena , for the idea of a Dragon Jon.
Jonathan Kent looks like his Dad. He has his skin tone, dimpled smile, and curly black hair. But all the rest of him he inherits from his mom.
Jon gets Lois's humour, intelligence and scales.
Her husband may be an invulnerable alien hero but Lois is a Dragon from the days of yore that walks around in human skin because that way she can drink sugary coffee and destroy corruption.
Both protect the world but in very different ways.
Lois uses her draconian instincts to hoard knowledge and share her hoard with the world when needed. That's enough for her. The world rarely needs her teeth to defend it.
Her darling son probably will not get the same choice.
For all that Jon is vaguely human shaped most of the time, both sides of his family are legend. The legacy of Superman just happens to be current, and one the baby dragon expects to live up to one day.
But for now, Jonathan Kent seeks comfort in his hatchling scales and the warmth of his mother's nest.
He is as happy as a half Dragon half Alien can be.
He can fly even without his wings out, and while he has to stick to his human shape in school,at home, he is free to wear his claws and tail proudly.
Jon takes pride in being a Dragon, like his mom. As a ten year old kid, he thinks it's awesome. Both his parents are so cool!
Jon loves his teeth and claws.
He is often found curling up at his mothers side amid her nest of hoarded documents in the Cave his Dad built them under the farm. (Even though he is rarely allowed inside, A Dragons keep tends to be a private thing. Clark has the Fortress of Solitude he can say nothing even if he pouts.)
But Jon knows he isn't a normal dragon, even by half Alien standards.
His mom worries about his lack of a hoard. it's apparently essential to a young dragons health, but Jon just hasn't found anything he wants to collect yet. Not gold or books, even baseball cards lack appeal.
Lois tries absolutely everything to try and get her baby to fixate and build the hoard he so clearly needs, but nothing holds Jons interest. Nothing fascinates him.
That is until Jon meets Damian Wayne.
Damian is fresh from the League of Assassins, the newest Robin, and infuriating.
Jon wants to keep him forever.
The first time they meet Jon is strapped to a table for dissection one that he could easily break out of if something in him stills at the sight of the infamous fifth Robin.
The second time goes a bit better when they are forced together by their fathers, Jon makes a fool of himself in front of Damian because he is using all his focus on not grabbing Damian and secreting him away home or to a cave somewhere where Jon can keep him safe and content for centuries.
Damian, luckily, doesn't pick up on it, too busy trying to prove himself to Jon and Batman.
What Damian doesn't know is that he is already perfect in Jon's eyes. He is his hoard, after all. Even as he orders Jon about and defends his need for independence, Jon can't help thinking he's wonderful.
Jon barely finds the strength to fly away from Damian when his Dad all but carries him out of the batcave. He is so excited to tell his mom. He finally found his hoard!
Lois is more than a little horrified. She has never heard of a Dragon hoarding a human.
She tries to divert him and introduces other things he can hoard instead of the son of Batman. It does not go well.
Jon starts collecting knives, art supplies, and even romance manga in the original Japanese. Lois looks at the piles of things her hatchling collects and is at first very confused by his choices.
Her limit comes comes when she finds a tiny black kitten in the cave alongside Damians hooded cape.
Lois resolves to meet Damian Wayne and assess how big of mess this is going to be. So she does the natural thing and calls Alfred Pennyworth to set up a meeting over tea.
What she finds is not what she expected. Damian is harsh and prickly but kind and loyal in a way that she would have thought impossible of an ex assassin.
She sees it in the way he treats his pets and how he compliments her work in taking down corrupt corporations.
Damian excitedly shares his own research into geology and environmental conservation that impresses her greatly, and Lois makes a mental note to make copies to add to her own hoard later.
Lois discovers that Damian even befriended a dragon bat! A distant cousin to her own species! And while Lois still frets at Jon hoarding a single person, she doesn't exactly disprove of his choice.
Damian Al Ghul Wayne has been through much. Maybe he can match a Dragons intensity.
Lois adds a bed to the cave under the farm in preparation, and Jon picks out emerald green sheets and a dragon plush for it.
They fill the cave with everything a human may need to be hoarded comfortably.
The only thing left is to inform Damian of the existence of dragons and his status as Jons hoard.
Jon has a plan that includes the kittens, anime marathons, and sleepovers in order to slowly warm Damian to the idea of being part of his hoard.
So far, said plan seems to be working. The Supersons form so that Jon can protect Damian during patrols.
He sates the need to hoard his new best friend by collecting Damians doodles and hoodies for now, but Damian gets suspicious when his mask and several blankets go missing.
(Jon doesn't think it counts as stealing if it's for his hoard. that's what his mom says.)
Lois prepares books on Dragons for when Jon eventually tells Damian of his other heritage and proposes the idea of being hoarded.
Jon is sure it'll be a hard sell, but if he goes on like this much longer, he might just lose his mind.
His Lois is getting more and more worried he is becoming unstable.
Unfortunately, Damian doesn't get much of a choice, as Bane makes the mistake of harming Damian in front of Jon.
The Supersons are on patrol in Gotham when there's an Arkham breakout. The rogues have co ordinated to take down the bats.
The boys are left facing Bane and Killer Croc alone.
Jon sees Damian fall to the ground under Bane and Crocs combined efforts. He doesn't fly fast enough to catch him.
Jon doesn't even realise he is transforming into his true form before he is forcing the rogues to dodge his teeth and tail careful to keep Damian safely tucked away between his claws where no one can touch him.
Having a dragon with laser eyes trying to kill you makes Bane and Croc stay in Arkham for a very long time out of sheer terror. The other rogue write their description of a dragon with purple eyes off as delusion.
Once Bane is dealt with, unconscious for the bats to find, Jon lifts Damian up and, as gently as possible, flies back to the farm where he can ensure he is never harmed again.
Damian wakes up to a kitten on his chest, and his best friend wrapped around him in a larger cave than his father has.
"Jon? What happened?" He asks his voice rough from sleep.
The younger boy startles awake and grins at him. "Damian! You're awake! How are you feeling?! Does it hurt?!" The questions come so fast it makes Damians head spin.
"I'm fine but where are we?" He starts absent mindedly putting the kitten in his arms.
Jon blushes "Well you see..." He is quickly interrupted by a large scaley animal Damian hadn't noticed before in the background.
"Oh yeah, that's my mom!"
The Dragon waves at him "What?!"
He debates passing out again in hopes when he wakes next the world will make more sense.
The explaination he gets is unbelievable and considering his grandfather is a functionally immortal assassain that is saying something.
Lois does most of the explaining while Jon transforms and starts preening Damian.
The boy ignores it for his own sanity.
Lois tries to impart the importance of a hoard to deagons health, how Jon needs him to stay more person than beast.
Dragons that loose their hoards go mad and get destructive before fading.
And Damian can hear the fear, the desperation Lois has for her son and Damian knows that he would do whatever it takes to keep his friend safe.
Hestiantly he agrees to be hoarded for a while. Its just until they can find a way to keep Jon sane without trapping Damian in the Keep for the eest of his life.
Damian will never admit it but he all but melts when Jon excitedly curls around him.
He is also very impressed and interested in Lois's hoard though he knows better to touch it without permission.
He is even more impressed with the Damian collection Jon has amassed for him including a kitten now dubbed Smaug.
(Lois rolls her eyes at him but Jon likes the name.)
Damian learns Dragon history and the rules of the keep, which include things like quiet and no mess and finds himself relaxing for what might be the first time ever.
The only issue is that in all the excitement they forget to tell Bruce and Clark about the situation.
Only for Batman to track his son to the Keep three days later he is the attacked by not one but two pissed off dragons.
Damian calls them off from under a sleeping kitten and a mountain of blankets. Jon does so reluctantly but Bruce is ruthlessly evicted from the cave by Lois.
Safe to say Damian doesnt mind bing hoarded for a few days longer especially after seeing the look of his fathers face.
Clark mediates even as he pouts because how come Damian is allowed in the Keep Lois!!
Jon eventually learns to hoard Damian while letting him leave even if they do return to the Keep more often then not after missions.
Jon savours the closeness, the trust Damian places in him. Damian likes feeling needed and wanted.
Everyone knows to never touch Damian unless you want to earn not only Jon but also Lois protective wrath.
Damian endures said overprotective tendencies with an eyeroll and a smile because everytime Jon goes too far he gets a new sword or pet in apology.
The boys grow together hoard and dragon even if they are uncoventional.
Its no suprise when many years later Lois finds them kissing in the keep. New rules are added much to Jons embarassment.
