AN: What if Killer, Kid and Bonney were siblings? See yourself.
Some drabbles in random order because great headcanon and I was too lazy to write an actual fic. Maybe later. Vergina-spva, don't blame me for anything ;D
AGE: Killer - 12, Kid - 7, Bonney - 6
Killer sighed, but didn't stand up from the sofa he was lying on. He should stop his younger siblings before they broke something. Again.
"Kid! Bonney!" the blonde called out in an attempt to catch their attention.
He cursed under his breath. It seemed like he didn't have a choice but to stand up.
"Kid." he growled, grabbing his younger brother's arm and pulling him away from their sister.
Not that he had to protect her from him. Hell no. The pink-haired girl was a hell of a fighter. The redhead had simply been closer to him.
"But Killer! She destroyed my ship!" the young boy whined, making his older brother roll his eyes.
"Bonney! Apologize!" he commanded, letting the pouting boy go.
"No! He ate my last slice of pizza!" the girl shrieked.
At that, Killer simply turned around and marched out of the room. He didn't care if they killed each other. At least it would be peaceful again.
AGE: Killer - 20, Kid - 16, Bonney - 15
"What did you say, fucker?" Kid yelled at the boy in front of him.
"N-Nothing." the usually so fierce youth was almost crying by now.
"Oh really? So you are telling me that I imagined that you just told your little shitty friends that you asked my sister out as a joke?! As a motherfucking joke?!" the redhead growled. It was enough for the boy in his arms to really start crying.
But Kid didn't stop. He had to make sure that none of these idiots would hurt Bonney. "Listen, bastard! If you ever just look at her again I will fucking castrate you. Understood?"
The other youth nodded. He definitely wasn't going near somebody with such a brother.
"Good." Kid smirked, happy with himself, before punching the guy a last time for good measurement.
AGE: Killer - 19, Kid - 15, Bonney - 14
"Kid?" Bonney peeked into the redhead's room. He was currently sitting behind his computer and drawing something.
"What do you want?" he growled. Why didn't she understand that he hated being disturbed while drawing?!
"Umm.." the girl was bright red. "I-I..." she simply couldn't bring herself to say it.
The redhead sighed, putting down the pen and turning around on his chair.
"Close the door and sit down." he commanded and Bonney obeyed for once.
"So what's the matter?" Kid asked, watching his younger sister carefully.
"Well, I... There is somebody I like!" she blurred out finally, making the redhead jump up in surprise.
"HELL NO!" he yelled. "Go to Killer with shit like that!"
"B-But he will kill him and tell me that I'm too young for a boyfriend." Bonney looked really mortified by that thought.
"And what makes you believe that I won't do exactly the same?" Kid glared at her.
"Because I know that you are in love yourself!" she gave him a cheeky grin.
"WHAT? NO!" Kid's face turned red immediately, while Bonney burst out laughing.
"So it is true!" she cheered. "You have a crush on Trafalgar Law!"
"YOU LITTLE-" the redhead barked, but the girl already ran out of his room, happy that her plan worked so well.
AGE: Killer - 23, Kid - 18, Bonney - 17
"What the hell is going on?" Killer barely hid his surprise as he walked in on his younger siblings doing their make-up in the bathroom, both dressed up for going out.
"Ah you are already back from college?" Bonney shot him a look, while Kid didn't pay his brother any attention and continued applying his eyeliner.
"Where are you going?" the blonde asked, staring at his sister.
"Isn't it obvious?" she grinned at him.
"Kid too?" Killer frowned. The redhead never went on dates. Ever. "Who is the lucky lady?" he asked.
"It's a guy. Trafalgar Law!" Bonney announced cheerfully. "You know him. He is a year your junior."
Killer's jaw dropped at that. He had been prepared for anything: Nami, the crazy ginger from his class, Perona, one of Bonney's closest friends and even some guys like Heat who had admired Kid for a long time. But not the medical student who was more than nuts.
"You are joking." the blonde muttered with a gravely voice.
"No, she isn't." Kid, who has just finished applying his lipstick stated as he passed his older brother on the way out of the bathroom.
Killer sighed. "And with whom are you going out today?" he asked, sounding almost defeated.
"Basil Hawkins." Bonney reported, grinning happily.
The blonde only sighed before turning on his heel and marching out of the bathroom. This was hopeless. Both his younger siblings decided to date the craziest people they could find.
He pulled out his phone and dialed a number.
"Yes?" a female voice came from the speaker.
"Do you have time? I feel like getting drunk." Killer answered.
"Your siblings again?" the woman asked.
"Yeah."
"See you in ten."
