ooh but what if there's like strict omega-handling protocol in rescue hero work because an omega in distress is like primed to instinctively trauma-bond to whoever saves them. so heroes are supposed to like, call it in when they find an omega in like, advanced distress, because if they're an alpha and they go near the omega, they're likely to trigger this mutual, problematic situational bond that can be hard to shake after without destabilizing the omega further
and when bakugo finds an omega like nearly shut down from distress in a disaster scenario he radios it in like he's supposed to - but then his ear comm crackles that it'll be thirty minutes before the recovery team can make it there, and the disaster is still like...very ongoing. he keeps his distance while he can, trying to follow protocol as he calls to you periodically to tell you he's there and help is coming...but when the wind shifts and the environment turns suddenly more dangerous, the choice is made for him. like, what is he going to do, just leave you to die instead of risking some temporary whatever that probably won't even happen since he's got his alpha shit so locked down? nah.
he waits til the last possible minute, truly he does (he's not looking forward to the getting-chewed-out he'll get for breaking protocol like this), but when the structure you're stuck in groans in warning, he snaps into motion without much conscious thought.
and yeah, you're....yeah. you're an omega, sure enough, and panting, wide-eyed, bone-still with instinctive distress. you're stiff like a board when he carefully extracts you from the rubble, your breathing tight and shallow, and shit, maybe he shouldn't have waited so long, he thinks, as he tucks you against his chest and figures how best he'll get you out of here without bringing the building down around him.
he's relieved when he feels you notice him. when he feels you sense his presence, his buried alpha-nature, because your breathing deepens and you soften in his arms. shifting, curling towards him and wrapping yourself around him as best you can. easier to hold as he works the both of you out of this death trap, as you huff softly at his neck and make plaintive whines at his throat.
it'll be fine, he tells himself, as he clutches you tight and just manages to clear the building before it begins to crumble to pieces. he's just making those responding, low chuffs to your soft whines to comfort you, alright? normal hero shit. and yeah his heart is beating oddly hard as he finally gets away enough to pull you back from him to look you over, to see if you're bleeding or if you have anything broken, and when you make a pained sound of protest at being separated, he clutches you back against his chest, his arm wrapped tight around you as he moves as carefully as he can to not jostle you as he moves through the wreckage and barks into his ear comms for a med team.
you're trembling and whimpering against his throat as he finally gets you to the perimeter of the disaster area to where med teams are waiting, and his hands are hard on you as he holds you close to keep you from scrambling up his body to get even closer to him.
the first emt he reaches freezes when he sees bakugo appear with you in his arms, his eyes widening. "oh," the emt says. "she's - she's in distress, you can't be - you shouldn't be - "
and bakugo just snarls, his heart fucking pounding in his chest (why? why is his heart racing so hard?), growling at the emt to fucking help you, obviously it'll be fine, and what did the emt want him to do, leave you so the recovery team could find a corpse instead?
but when the emt reaches for you in his arms, bakugo's entire body stiffens. going rigid, a low, ragged growl rumbling up his throat and through his clenched teeth. and bakugo is still growling, his hackles raised as the emt takes a step back and radios over comms that they need a recovery team at the med tent asap, his eyes wide as he takes a step back from where bakugo is clutching your softly whimpering form to his too-tightly, all but baring his teeth at the emt.
bakugo wakes up in the hospital a few hours later, his neck aching from the tranq they had to stick him with, and when he blinks up at the ceiling and feels a deep, aching flutter in his chest that tells him, as surely as if spoken aloud, that you're in the next room over, and you're still in some amount of distress, he scrubs his palm over his face and mutters, "fuck", before he feels another aching flutter and is on his feet in an instant. unable to stop himself as he goes to you, his alpha pacing and grumbling in a way that he knows won't settle until he has you back in his arms and is soothing you.
