Just so you know, this is my first writing piece and will therefore be absolutely horrible. But I will do my best. Just in case I can't make a summary for no reason, this story will be a Spider-Man and Avengers crossover, and Peter will be an orphan trying to take care of his "sister". Well, for the beginning. I have no idea how to do this. Also, I'm changing the sister's name, so those who read this earlier, sorry if you liked the original name better.

This will be a human's thought. Or a not-monsterous thought.

This will be a monster thinking, though it will not happen often.

(This will be me speaking, and it will hopefully not happen that often.)

"This will be regular speech for a not-monster."

"This will be a monster talking."

These are author notes. Without further ado, let's begin.

(Just so you know, I do not have a proof reader, so I will have many mistakes. A fair warning for many mispelled words ahead.)

BEEP. BEEP. BEEP. BE- SLAM! Peter's hand slammed into the alarm clock, cutting it off abruptly. Groggily reaching for his glasses, Peter groaned and rolled over so he could sit on the edge of the bed. As he put on his glasses, he looked over at the time and immediately began throwing everything onto the floor.

"I'm going to be late again!" Peter half shouted as he pulled up his jeans and pulled a red hoodie off a hanger. He ran out the door as he wriggled his way into his hoodie and slipped halfway down the stairs.

Paying no attention to his now bloody nose, Peter pushed himself off the floor and barreled into the kitchen, jumping into his seat as Aunt May placed a plate of bacon and eggs and a glass of water onto the table.

"Late again, Peter?" Uncle Ben chuckled to himself as he watched Peter inhale his bacon and chug his water.

Peter hugged his aunt briefly, calling over his shoulder "Thanks for the food!" as he scramble to collect his things before dashing out the door with a "Byeseeyoulaterhopeyouhaveanicedayatwork!"

Peter glanced at his watch. It was 7:35. "SHIT!" Peter chanted in his mind as school started at 7:50, and the bus took 20 minutes to get to the school. (Sorry, should have warned you there would be cussing. Hey, it's an Avengers crossover, of COURSE there's going to be cussing.)

Even with Peter running as fast as his legs would allow -which wasn't that fast, just look at Peter's grade in gym- he still got to school at 8:20, half an hour late to school. "Aww, damn," Peter cussed under his breath. "It's only been a month of school and already I'm half an hour late."

After a harsh scolding of his English teacher Mrs. Parker (I'm going to give random names to teachers, just letting you know.), Peter sat down in English with Flash occasionally throwing balls of paper and once a rock. That did not go unnoticed by Mrs. Parker and she immediately gave Flash detention.

Obviously Flash blamed Peter for his detention and as Peter trudged out of English and headed to Mr. Harrison's math class Flash slammed him into the lockers. "You're so going to pay for that detention slip, Penis Parker," Flash hissed, and Peter bit back a retort as Flash's fist dug into his cheek. His lackeys followed close behind laughing as Flash threw blow after blow on Peter. Peter just threw his arms up in defense until Flash decided Peter had enough and left Peter there laughing with his lackeys.

Peter huffed and brushed himself off, wincing at every movement he made. Reaching down for his backpack, Peter pushed away any pain as he ran for Mr. Harrison's classroom hoping beyond hope that he would make it in time. Thankfully Peter made it just before the bell rang, since he didn't wish to disappoint his favorite teacher by being late.

Near the end of math class, while Peter's class worked on the math homework due tomorrow, Peter's phone vibrated in his pocket, thankfully not ringing. Peter spared a quick glance at the text sent to him by Aunt May, asking him to come home, and Peter quickly gathered his things and walked up to Mr. Harrison's desk.

Mr. Harrison glanced up from the tests he was still grading from yesterday, sighing as he saw Peter's packed things. "What happened this time?" Mr. Harrison's tired voice asked, and Peter's face heated up from embarrassment.

"My aunt asked me to come home and help her with something at home, since her back still hurts," Peter mumbled, barely loud enough for Mr. Harrison to hear. Peter shuffled his feet, not looking at Mr. Harrison's face.

Mr. Harrison let out a tired sigh as he filled out a pass for Peter to leave the school. "I'll let you off this time, but please tell your aunt to stop calling you home in the middle of the school day, okay?" Peter nodded vigorously, and Mr. Harrison handed over the leave pass.

"Here's the field trip form that your science teacher would have handed to you," Mr. Harrison said, handing a sheet of paper to Peter, who snatched it and left as quickly as he could. After another heated conversation with the secretary for leaving school early AGAIN, she waved him out the door and Peter began his tiring walk back home.

Aunt May had finished making early lunch for Peter by the time Peter got back home, which was around 11:25. "Aunt May, I'm home!" Peter yelled as he ran up the stairs and changed into his pajamas.

"Come downstairs, Petey!" Peter groaned half heartedly at the nickname Aunt May lovingly gave him. "I have a surprise for you!" At this Peter perked up. A surprise? But it's not even close to any holiday or celebration.

Curious, Peter opened his door and padded down the stairs, wandering into the kitchen while wondering what Aunt May's surprise could be. He certaintly wasn't expecting what aunt May was holding in her arms, grinning at Peter's shocked face.

"SURPRISE!" Aunt May cheered, placing the child on the floor so she could toddle around the house. "Isn't Mara just the cutest thing you ever saw?" Aunt May gleefully said, watching happily as the small child wandered over to Peter.

Peter gaped at what he saw. "..." Peter was at a lost for words as Mara giggled and lifted her arms up toward his face, clenching and unclenching her hands while bouncing on her feet.

Aunt May shook Peter out of his shock by saying, "Peter, it's not nice to keep her waiting." Peter looked down helplessly at tiny Mara waiting to be picked up.

"Pick me up! Pick me up!" she whined, tears welling up in her eyes when Peter didn't pick her up. "Pwease?" Mara put on her best puppy dog eyes, which broke Peter's heart.

Peter smiled. "Okay," he said hesitantly, not sure how to pick her up. He looked up at Aunt May. "Umm..." Aunt May caught on to what he wanted to ask.

"Don't worry about hurting her, after all she's such a big girl. Isn't that right?" The little girl nodded, puffing up her chest with such pride Peter had to hold back a snort of laughter. "Anyways, you hold her like this..." Aunt May demonstrated by picking her off the ground with ease and twirling Mara around.

"Do that again!" she cried as she was placed on the floor, stumbling a bit before falling to the floor with a laugh. Aunt May laughed with her, but it was cut off once she got a good look at Peter's face.

"What happened?!" Aunt May gasped, examining Peter's bruises, bloody nose, and swollen eye. It had healed somewhat, so you couldn't tell unless you paid attention to his face, but he still looked like a bus ran over him.

Peter gently pushed Aunt May away. "It was just a prank, nothing to worry about," Peter said, hoping his aunt would drop it. It was a lost cause, though.

"Yeah, and I'm the richest gal in the world," Aunt May huffed, clearly unimmpressed by Peter's blatant lie. "It was those bullies again, right?"

"Aunt May, it's nothing to" Peter began, but was immediately cut off by Aunt May.

"Why don't you tell me their names? Why won't you let me help?" Aunt May scolded, glancing over at the little girl every once in a while to make sure she was okay. "If not me, why don't you turn to Flash? You two were such good friends when you were children."

Peter snorted. If only Aunt May knew. "Mara, no!" Aunt May shrieked as she pulled the small girl away from the outlet Thana had been reaching for, clutching her close and breathing heavily.

Mara looked up at Aunt May's face, having no clue just how much fear she had caused in Aunt May. Aunt May let her down once her breathing calmed, and she said, "Mara, don't touch those. They could kill you." Mara tilted her head to the side as she absorbed this information.

"They could kiw me if I touch them?" Mara said, understanding sinking in. Mara's face seemed rather calm, but she glanced over at the outlet warily, letting Aunt May and Peter know that she caught on.

"Yes," Aunt May breathed out, relief flooding her facial features. "So don't touch it, okay?" Mara nodded, feeling pleased that Aunt May was happier now.

The sound of the landline rang throughout the house, and Aunt May spared a brief glare in Peter's direction. "This talk isn't over young man. Go have some fun with Thana, alright?" Aunt May didn't wait for an answer before she left for the phone.

A tug at Peter's pajama pants caught Peter's attention, and he looked down to see Mara smiling. She instantly said, "Pick me up! Pick me up!" Peter let a smile spread across his face as he attempted to copy how Aunt May picked her up and almost dropped Thana in the process.

Aunt May's laughter rang out through the house as she excitedly rambled through the phone, and Peter brought Mara upstairs so he could show her his favorite videos and games on his computer. She was fascinated by the computer, and immediately wanted to know how it worked.

The rest of the day before Uncle Ben arrived in the house was spent with Peter showing her how the conputer and the internet worked, as well as showing her some funny videos and challenges. Like the Try Not to Laugh challenge -which Mara failed miserably at- and the How Long Can You Hold Your Breath challenge -Peter was pretty sure Mara had set a pretty much unbreakable record of- and teaching Mara how to play games on the computer.

Peter had such a great time with Mara he almost forgot about the impending conversation that Aunt May wanted. "Peter, it's time for dinner!" Aunt May called. Peter turned to the clock, bewildered at the fact that time had flown by so fast. Sure enough, it was 7:12 pm, the normal time for dinner in the Parker household.

Peter held on to Mara's hand as he guided her down the steps, taking extra care to make sure she didn't trip or slip. Then Mara ambled her way into the kitchen, with Peter walking right behind her. Aunt May saw the two of them and gestured for them to hide from the view of the dining table. Peter wondered why when it struck that Uncle Ben probably didn't know about Mara yet. He gently stopped Mara from advancing into the kitchen and shushed her to keep it a surprise.

"Ben," Peter heard Aunt May begin, "I have a surprise for you!"

"Really?" That was Uncle Ben. "Well, where is it, May?"

Aunt May peered around the corner and gestured for Peter and Mara to show themselves. Peter loosely held Mara's hand and gently pulled Mara into view for Uncle Ben to see. "Surprise!" Aunt May and Peter cheered, with Peter picking up Mara and bringing her closer to Uncle Ben.

Uncle Ben's face was similar to that of a goldfish, his mouth hanging open. Mara reached out for Uncle Ben, and Peter set her down so she could walk towarda Uncle Ben. Uncle Ben got up and lifted Mara upwards, feeling more happy than shocked at this point. "Who have we here?" Uncle Ben said, throwing Mada up lightly before catching her again, Mara's laugh like little bells.

Aunt May set up a chair for Mara to sit upon. "Isn't she just adorable?" Aunt May asked, squishing Thana's cheeks and lightly pinching them.

Uncle Ben set her down on the chair and pushed her in. "What's her name?" he asked.

"Mara," Aunt May sweetly replied, setting down a plate of spaghetti and a fork, along with a juicebox in front of Mara. "I saw her at the orphanage and I just couldn't help but adopt her. She seemed to be bullied by the other kids as well, for some reason," Aunt May added, worry filling her tone.

Peter sat down, head bent down as he stuffed spaghetti into his salivating mouth. "And speaking of getting bullied..." Aunt May began, her tone matching her glare. Peter gulped down his spaghetti, hunching his shoulders and wishing to hide. "Peter, why don't you look up at me while I'm speaking?" Aunt May said, her tone sounding somewhat threatening.

Peter sheepishly raised his head, and Uncle Ben gasped lightly at the injuries on his face. "Peter, what happened to you? Was it those bullies again?"

Aunt May said, "Yes, it was. And don't you dare deny it, Peter," she added as she saw Peter's mouth open to retort. "Honestly, thinking you can just explain it away by calling it a prank."

Uncle Ben looked at Peter with worry. "Peter, why won't you let us help by saying something?" Mara looked between the three of them, her head swiveling like she's watching a tennis match.

Peter sighed. "Look, it's really nothing."

Aunt May slammed her hand on the table, causing Uncle Ben and Peter to jump in their seats. "Peter, don't lie to us!" she yelled, her eyes welling up. "Why do you keep saying that it's nothing?!"

Peter bit his bottom lip, looking away in shame. Uncle Ben placed his hand on top of Aunt May's, calming Aunt May down. Uncle Ben turned to look at Peter. "Peter, please don't keep pushing us away. We just want to help."

Peter nods silently. The dinner continues on solemnly, with Mara cheering up everyone a little with her antics. Peter gets up to go to his room, placing his dirty dishes in the sink. "Peter," Aunt May starts. "Can Mara sleep in your room tonight?"

Peter stared at Aunt May, in some kind of shock. "What?" Peter managed to get out.

Aunt May looked down at the table, then at Mara, and back to Peter. "Mara doesn't have a room of her own, and we don't have any room in our room. Don't worry, Ben'll set up her bed, but she'll have to be in your room. Is that all right?"

Peter looked over at Mara, and contemplated heavily. "Sorry, I just realized it's a bad idea," Aunt May hurriedly said.

Peter raised his hands in surrender. "No, it's okay!" Peter said without thinking. "She can sleep in my room until she gets a room of her own."

Aunt May looked at him concerned. "Are you sure?" She said, her shoulders sagging in relief.

Peter bit his lip, really regretting it but not wanting to burden Aunt May even more. "Yeah, I'm sure!" Peter beamed, hiding the remorse he felt of speaking without thinking. Aunt May sighed in relief and picked up a tissue to wipe off the spaghetti sauce smeared on Mara's face.

After he help Aunt May wash the dishes, he led Mara into his room and played with her while Uncle Ben set up a twin sized bed for Mara and hung up curtains around each others bed so both could have some resemblance of privacy. Soon enough Peter had them sign the field trip paper, helped Mara brush her teeth while brushing his teeth, and tucked Mara into bed.

Mara snuggled into her soft sheets, while Peter laid in bed thinking about the horrors that are going to come with having a little sister in his own bed. Peter groaned mentally as he rolled onto his other side to attempt some sleep. "Parker luck sucks," Peter whispered, mentally preparing himself for tomorrow.

Woah, that chapter was WAY longer than I expected. Hope if you decide to read this that you liked this chapter. If I can publish this chapter in the first place.
