Younger Big Brother - Batfamily x Reader
Requested by Anon - You’re Damian’s older half-sister, and not as well-trained as he is. Most of the time he feels older than you since you act more young while Damian wants to be older and respected. Despite your differences (and fights), you are close as can be, literally and mentally. That is, until you’re kidnapped and Damian sneaks off to find you.
Damian was already at the breakfast table when you entered the kitchen. You moved around, gathering a orange and some cereal before you sat down across from him.
“Good morning, Damian,” you greeted happily, giving him a big grin before digging into your cereal.
“TT,” Damian huffed at you, wrinkling his nose. He went back to his breakfast without another word. The two of you fell into a comfortable silence, content with each other’s company.
Soon, Bruce drifted into the kitchen, dressed for work. He gathered his own breakfast before joining you and Damian at the table. You were eating your orange at that point, cutting it into slices.
“(Y/N), I want you and Damian to train today. You kept dropping your left when you were taking out that mugger last night,” Bruce instructed, spreading butter onto a piece of toast. You pursed your lips as Damian opened his mouth.
“I doubt a day of training will help her with that,” he replied snarky. You rolled your eyes at him, putting a unpeeled orange slice in your mouth. Making a face at Damian, the orange slice hiding your teeth. Damian glared at you in disgust. “Grow up, Sister.”
You laughed, biting the orange off of the peel. “Funny, you say that Damian since I’m older than you.”
“TT, you don’t act like it,” Damian retorted with a glimmer of a smile on his face. Bruce watched your exchange, amused.
“As I said, I want you two to train today,” Bruce interrupted, taking a bite of his toast. “If there is no improvement by patrol tonight, (Y/N), you will not be joining us.”
“Really? That seems a little drastic,” you protested, forgetting your food to glare at Bruce. “Just because I’m not very skilled in fighting yet, doesn’t mean I can’t help out on patrol.”
Bruce’s voice took on a stern tone. “No, (Y/N). You know what my rules are about patrol.” You wrinkled your nose, hating his logic.
“But it’s not fair,” you whined, standing up from your chair. “I’m not useless.”
“(Y/N),” Bruce warned. You huffed, looking at Damian. Meeting his eye, you both shared the same thought.
“I’m going to start training then,” you snapped, leaving the room. Damian got up to follow, giving Bruce a glare before exiting. Bruce shook his head in disbelief. He was still surprised by the connection between the two of you. Somehow, you and Damian were an amazing mixture of brother and sister that he had ever seen. Arguing and fighting one moment, teaming up against him the next. Despite that fact, Bruce was glad that you both had each other.
