Bat-Family and Bat-Mom-(Batman)One Shots

Big Brother Trouble!

This one-shot was suggested by the lovely @ginger300. It's a cross over with Avengers and luckily I'm super obsessed with them too. Who says you can't like both Marvel and DC? No one that's who! Okay calm down, *breaths*. Enjoy the story!

        Who new being Tony Stark's little sister could be so much trouble? You hadn't heard from your big bro in years so when he suddenly shows up in Gotham one day with the other Avenger's, explanations are mandatory. When he first came, you were at work with Bruce and didn't even know about him until it came up on the news. You had dropped your coffee and ran out of the office faster than the flash. Who had been seen circling around the city and you hoped to catch him and get an explanation out of why he was here. When you left your home you two didn't leave on the best of terms, him not even saying good bye to you. You walked down the streets of Gotham, stealing glances at the sky to try and spot him. Just as you were about to give up and go back to the office, you saw familiar red and yellow armor. Following him on the roof tops were the rest of the Avengers. You had grown close to Clint and Natasha and were excited too see them again, but you weren't too excited to see Tony again. Oh yeah one more thing, Tony doesn't know that your in Gotham and that you are married with four adopted sons. Woops? Eh whatever, a good surprise once in a while is okay, right? You turned around and made your way back towards Wayne enterprises. You kept glancing to the buildings across the street and saw them walking there. Had they spotted you? Shrugging it off you noticed Bruce walking out of the building tiredly. You rushed forward, hoping not to miss the limo. You walked up to Bruce, taking his suitcase from him. He smiled you, kissing your forehead before pulling you into the limo. 

        Mean While, the Avengers were running from rooftop to rooftop, following a limo. Natasha had claimed to have seen Tony's sister, so of course they had to see if it was true. When they reached the limo's destination, their suspicions were correct. Tony felt so guilt on the way you guys left things that he needed to apologize. As they watched you get out of the car, Tony furrowed his eyebrows at the sight of you kissing a man. One scan of his figure identified him as Bruce Wayne, billionaire play boy. Even though he was basically the same, who didn't want his little sister hurt or broken hearted. 

        "Someone's watching us." They heard Bruce say, wrapping a protective arms around your waist. He scanned the area, his eyes landing on the Avengers. He had no idea who they were since their paths had never crossed. He pushed you behind him, glaring hardly at the bushes. You of course had a slight idea at who was behind there. You pushed Bruce's hand away and walked over, Bruce hot on your trail. You stopped in front of the Avenger's hiding place and squinted your eyes.

        "Come out. Now." You demanded, resting your hands on your hips. Slowly, the avengers made their way out eyeing the man behind you. The hulk was back to banner, and you mentally sighed in relief.  You grinned at Clint and Natasha, avoiding Tony's eyes. "I knew it was you guys. You really can't hide in this city when you have a the Hulk and Iron Man." You mused, laughing lightly. Clint nodded and Natasha smiled. 

        "How do you-" Bruce started but you stopped him with the wave of your hand.

        "I'd rather explain it once than six different times. The boys should be home by now. Oh and Tony, your an uncle." You stated motioning the team to follow you. Tony had his mouth open while he followed you, not believing what you were saying. When you opened the door you ushered them to sit in the living room with Bruce. They nodded, inspecting the decorations of the house as they went. Once in the living room they studied Bruce, noticing how he's always scowling. "Boy's! Alfred! Please come to the living room we have guests!" You shouted from the foyer, kicking off your shoes and hanging up your coat. You entered the living room and rolled your eyes at the tension. Guess you have to start with introductions. "Avengers, meet my husband Bruce. Bruce meet the Avengers, and my brother Tony. You two should get along really well." You said sitting next to Bruce and entwining your hands. Tony glared at your hands, his protective brother instincts coming out. Soon five boys entered the living room, your boys and Alfred standing around you. You picked Damien up and rested him on your lap. "Avengers, meet my family. My eldest son Dick, second eldest Jason then there's Tim and finally Damien This is Alfred, Bruce's father figure and family friend. Boys, meet my brother and the Avengers. Tony, my brother, Clint or Hawkeye, Natasha or Black Widow, Bruce or Hulk, Thor and finally Steve or Captain America. Now on to how I know them. Well Tony is my older brother and I had left about a month after the team had formed. Me and the team lost connection for a while and I had no idea had to get back in touch with you guys so I didn't know how to well you know invite you too the wedding and tell you about all of this." You said rubbing the back of your neck embarrassed.
