#tiny!clark

-

Bruce wakes to the warmth of sunlight on his skin. He stretches languidly, feeling the pleasant aches in his muscles; remnants of a busy night. The sheets shift against his skin and the mattress is soft beneath him. He must’ve slipped off Clark’s chest sometime during the night.

one afternoon he falls asleep in the sun, and when he wakes up... at first he thinks it's a bug, buzzing around his face and he almost swats it away unthinkingly. but he notices something's off as soon as he raises his arm. dusty, their dog, is barking his little head off at him while clark tries his best not to freak out (he fails) as he realizes everything is suddenly so much smaller around him (no, it's just him that's so much bigger).

his ma and pa come outside to investigate. they've already accepted that their boy is a little strange and can do things other boys can't, but this...their hesitation doesn't come from fear of clark, just the natural human instinct of not wanting to approach something so much bigger than yourself, that hindbrain reaction that screams danger, but it's still hesitation, and clark notices. his chest twists and pulls and he wants nothing more than to shrink and shrink until he can hide beneath the floorboards where no one can see him, but he's stuck a great, big, lumbering monster. pa tries to approach and clark flinches away, afraid to hurt him, and his hand knocks against a tree and splits the trunk with no effort at all, a great crack in the air as wood splinters between clark's giant fingers.

they'd hide him in the barn except he's too big for the barn. clark is nearly inconsolable, curling up tight into a ball and hoping he'll fall asleep and wake up normal again. he can hide the strength, and the speed, and the lasers that sometimes shoot from his eyes, but he can't hide this.

martha wants nothing more than to gather her boy up in his arms and tell him it'll be alright, but he's too big for that, and so she hugs one of his fingers and presses her cheek to his hand, and tells him it'll be alright.

eventually when he's older, he learns to regulate his cellular structure at will to change his size. if he's had a little too much sunlight he feels the strange urge to grow, to vent some of that solar energy, but he doesn't like being so big and unwieldy and exposed. he never does it as superman, just when he can spare some time to go to the fortress when the need becomes too strong and he can be alone without anyone seeing.

and nobody sees - until there's a fight in metropolis and a building is about to collapse, and the only way to save it is to grow big. he tries not to think about it, to just focus on the fight at hand and holding up the building, but he can't not notice the stares and the shocked exclamations and the fearful gasps. he escapes to the fortress as soon as the danger has passed and expels all of the excess solar energy and curls up tight until he's small enough to fit into a teacup.

DCU | Pairing: Clark Kent/Bruce Wayne

Summary: Being shrunk to four inches is not the strangest thing to have happened to Clark in the last month, but it’s certainly irritating. He’s fortunate that Bruce is there to keep him company.

A quick little doodle for ya 🙂‍↕️

augh this is so difficult to answer and i've thought so much about both scenarios. there's already the innate size difference between absolute!kal and the chonker that absolute!bruce is, and a tiny kal would look so cute in bruce's beefy hands <3 imagine sol reshaping to look like dusty fairy wings, he would be stunning. and even though kal is unbreakable, bruce would still handle him with so much care with the way he looks like a fragile flower in his hands.

on the other hand i'm a sucker for characters who are used to being big and strong ending up tiny and helpless. well he's still batman so he wouldn't be completely helpless, especially if all of his gear shrunk with him. but he'd be so out of his element, having to adapt to navigating the world at an entirely different size, which is no easy feat. kal has to be so gentle with him, fussing over this little man 🤲 and bruce is SO flustered when kal manhandles him, bruce hasn't been held by anyone since he was a kid. it's the first time in a long time he's been overpowered and outsized and it's making him feel all sorts of things when clark only needs a single hand to lift him, when a single finger is enough to push him over.
