Okok hear me out: one of the boy's has a s.o with a water type quirk and can blood bend. And pffttt i totally didn't get the idea from avatar: the last airbender 👀👀👀
Oooohhhh. I see you, anon, I see you. I’ll give you one better, tho. I know this is a Hawks blog but, I think I can make something work with Dabi :3 Here goes nothing~ Also, hope headcanons and s.o/reader is alright!
• You were present at the fight between the Liberation Army and the League of Villains. You had been together with Geten, supporting him on the sidelines with a blank expression. Dabi didn’t pay you much attention. At least not until others tried to interfere with the fight. Friend or foe, you ravaged through those who approached them. The water that Geten didn’t freeze, you used, controlling it to slice some. Others, you simply seemed to control someway unknown to him, their bodies contorting grossly before breaking apart under your delicate ministrations. Those who survived yelled at you, calling you a traitor from a safe distance, but you didn’t mind them. You simply gawked wide-eyed at the blue flames and ice that collided with each other.
• After the fight and the unification of both factions you appeared somewhat interested in the League. Every member seemed to entice your curiosity though it didn’t seem to quite show in that blank expression of yours. Dabi found out why you stood by Geten’s side during the battle then, you were his younger sister. One that, although with a similar Quirk as his, used it in a completely different manner. As he controlled all kinds of ice, you controlled all kinds of liquid. Including blood. Suddenly it made since how those people contorted without you touching them. How they died, completely drained from their blood without obvious cuts. Yet you were unfazed. Completely expressionless.
• You approached Dabi out of the blue one day asking about his Quirk. Dabi refused at first, but with how incessant you were about it, he finally caved and showed you how it worked. It intrigued him to see how your eyes grew and seemed to gleam at the sight of his blue flames. But when you noticed that it began hurting him, his skin sizzling from the flames, you didn’t hesitate in grabbing onto his hands. Before Dabi had a mind to stop you, he watched intently as you used water from a small flask you seem to carry around everywhere to heal his burns. The sensation of it, although weird, was soothing.
• He asked you why you were on their side with a Quirk that could very well be accepted by society as a healer. Your answer: there was no point in only being half of yourself. Society would accept the part of you and your Quirk that benefited others through healing, yes, but if they couldn’t also accept that it could do just as much harm as good, then you wanted no part of it. Besides, she hated a society that hated your brother. Family was everything to you. Dabi called you an idiot with that statement and simple left you.
• Regardless of how he felt about you and your ideals, you were intrigued by him and his Quirk. Something so beautiful and at the same time so destructive. Like yours. Though Dabi was annoyed at first by your constant pursuit of him, he eventually mellowed down and grew used to having you around. You were easy to talk to, rarely lied if at all, and though expressionless for the most part like your brother, you were quite innocent deep down (it never ceased to amuse him when simple things like cute animals and delicious food would turn you into a dazzling-eyed child). After some time, if anybody asked about you, they would be pointed either to Geten or Dabi because if you weren’t with one, you would surely be with the other.
