Edited!! Thanks for the help!!!
Ok in this, Pete is 23, don't ask why, fight me and there isn't a lot of Iron Dad in this, just mentions. Peter and MJ are married too. This one is different and I don't think I will be doing it again.

Peter was holding a small pink raincoat in his hand. His girlfriend, MJ, was nowhere in sight as she was ferociously trying to tug a pair of leggings on their energetic daughter, who kept laughing and running away from her mother every time she got close. She groaned loudly when the three year old ran out of the pink themed bedroom and into the living room, where Peter was waited.

He spotted his daughter in nothing but a loose white shirt. He shared a laugh at her antics and scooped her up as she ran near, tickling her stomach. She squirmed in delight and giggled as Peter let his hands crawl to the sides of her stomach, her tickle spot.

He was shortly joined with his wife as the two worked together to shrug the pastel pink leggings over her and stuff a pair of pink wellies on her two small feet. Peter pulled the raincoat on her shoulders and took her hand, while MJ locked the door and together, they headed out as a family.

They swung the small girl in between them as they walked down the street to the bus shelter. She squealed happily and shouted over and over, "I'm Wonder Woman!" Her tanned wrists often broke free from her parents' and crossed her arms into the iconic pose of her heroine. They stopped several times for their daughter to jump in the smaller puddles on the pavement. Strangers awed and chuckled at the small girls' antics.

They sat under the bus station and waited for the correct bus to arrive. While doing so, the rain that poured down helplessly didn't seem to faze the family as they laughed and kicked water at each other. It was moments like these that Peter loved. Having fun with his wife and daughter, Isla. Her brown hair bounced around her as she moved, the color was inherited from her mother and the soft curls were taken from her father. She looked a lot like her mother however her eyes were distinctive and powerful much like her father.

"Can we get an ice cream?" Isla asked, turning her face to her father.

"Agua," he said, shaking his head. The little nickname had been a genius idea. Both MJ and Peter knew fluent Spanish and since their daughter seemed to adore the wet weather, the nickname was born. "It's too wet for an ice cream, the water may look clean but it's actually full of ...." He trailed off, waiting for her to finish the sentence as he and MJ taught her science a lot earlier.

"Bacteria!" She exclaimed, but frowned soon after as she knew that was a bad thing.

"Yes, exactly. If the water goes on your ice cream, you'll just be ingesting a whole load of bacteria, you could end up real sick." MJ spoke, immediately shutting down the idea. Isla's face fell and she groaned.

"Please?" She asked and stretched the word as long as she could before taking a breath. "Pretty please with cheeries, sprinkles, chocolate flakes, and magic fairy dust on top?"

"No, Agua." Peter said firmly. "No ice cream while it's raining. But I think Grandpa might have some at the compound." Isla's face visibly brightened and she smiled.

"Grandpa is awesome. He gave me my pink wellies, see?" She put her foot high in the air, another club they put her in was mixed martial arts and ballet which allowed her leg to go straight up. She was surprisingly flexible for a three year old. MJ and Peter nodded, their daughter had boasted about her new favourite shoes for months now, no matte what outfit she was wearing, wether it be a simple pair of dungarees or a full on bridesmaid dress, those pastel pink wellies stayed on her feet.

They got on the bus as soon as it arrived and told the driver to take them to the compound. He happily obliged and smiled down at the bubbly three year old.

"I like your bus," she commented. "Most of the buses are full or gross. This one is empty and clean." A habit she developed when being babysat by the avengers while Peter and MJ went out on dates was that she wasn't afraid to speak her mind. MJ wasn't sure if she should be happy or concerned about the new habit but shrugged it off every time, vowing to make Isla apologise and lecture her if she ever said anything mean or rude. So far she hadn't. Peter had never known his daughter say anything mean to other people or about other people, she was just an all around nice child.

The driver reached over into a jar and pulled out a red semi clear lolly pop and handed it over to the girl who happily accepted and began to eat it immediately. They took their seats and talked quietly to each other as others filled the bus. Isla could hardly contain her excitement as she bounced in her mother's lap while burbling nonsense about how Loki was the best Avenger.

"He's so nice and funny," She rambled, unaware that she said that four times already. "He plays princess tea party with me and everyone else and sometimes he is a cat and lets me pet him, he transformed into Grandpa once and everyone believed him..." she continued on but MJ and Peter had stopped listening after a while as they talked to the person in front of them about how taxes have gone down, like boring adults.

They soon arrived at the compound and was immediately met by Tony who was waiting impatiently by the entrance along with all of the other avengers. As soon as Isla caught sight of her grandfather, she screamed and sprinted towards him while shouting "Grandpa, Grandpa, Grandpa!" Tony immediately picked her up and swung her around. Excitement shined on his face as he beamed at his granddaughter.

"Hóla, Agua," he spoke, his Spanish fluency and his use of the popular nickname made the kid giggle. "Cómo estas, me gusta tu camisa, es fabuluso."

"Bien y gracias. Me gusta tu pelo," she patted the top of his head that was styled out of its regular mess. He chuckled and set her down before turning and hugging his son and daughter in law, who had finally caught up with their hyper three year old.

"Hi Dad," Peter said. He brought his father into a hug and separated for MJ to hug him aswell. "Missed you and the others."
