Hello readers there will be many changes in my story and I am going to list them out.
First of all, Peter Parker aka Spider man will be female. Her name will be Sanchi Mittal. Her description will be fair skin, big brown eyes, a small button nose, pink lips and rosy cheeks. She is just 12 years old in this story, i.e., during Homecoming. She has a small height of 5 foot. It will increase with time.
Everything has happened the way it did until Tony met her the first time in Civil War and found himself getting attached to her innocence. She was 11 and half years old at that time but her school records state that she is 13 and half and is a freshman in high school. Civil War happened as it did but Tony stopped himself and helped Steve and Bucky leave but took the shield as a memory. So, there are no hard feeling involved, though he is still wary of Bucky.
Homecoming happened the same but, in the end, when Aunt May finds out about her being Spider Girl, she chews Tony out and Sanchi becomes his personal intern with whom he develops a kind of parental love.
During the events of infinity war, she gets dusted at the age of 14. Then Endgame happens. Then Wanda Vision after which she befriends Wanda. Then Falcon and the Winter Soldier In which Sam and Bucky become her fun uncles. Events of Far from Home devastates her and she mourns Tony.
Note that Tony never married Pepper during the 5 years. This is because Pepper came out as lesbian and Tony as asexual.
Sanchi is now 15 years old and Aunt May died in a car accident during the blip.
Let's see what happens next…
Sanchi was alone in the lake house. Rhodey said that he would be coming the next day. She took the silence in the house as a bliss. The loss of her mentor still ached. Oh, what she would not do to reverse everything a start fresh. Not to make any mistakes and save lives but guess luck was not in her favour as it was merely impossible.
With nothing else to do, she laid on her bed and simply watched the ceiling. The lake house was beautiful but empty. The wind was pleasant and she soon found herself drifting into a deep slumber.
She saw a flash of green and her surroundings changed orange. The sky and the ground were orange and it was peaceful. She thought that she had seen this place somewhere, oh yeah it was the soul stone but what was she doing here. "You are here to save humanity my child" a soothing voice said. She startled and started looking here and there but could not find the source. She then gathered some courage and asked, "Why am I here?" "You are here to change the mistakes of your past and make sure Thanos never wins." The voice replied.
Sanchi was now confused as hell. "Why me only? There are people better than me." She inquired. The voice led out a chuckle and said, "Child you underestimate yourself. You are the best of all of them. Do you not want to save the universe?" Now that was Sanchi's weak point. She would do anything to save everyone. She put on a brave face and asked, "What do I have to do?"
"I knew you would agree. Now listen carefully I will send you back in time somewhere during homecoming. You have every right to change anything you want to change. I will send Stark's masterpiece EDITH with you. It will have information up to now. But with this gift I will take something from you. Your Aunt May will be dead only." Sanchi's breath hitched but she motioned her to continue.
"The Sorcerer Supreme at that time will be Yao or popularly called the Ancient One. You need to go to 177A Bleecker Street to get her help or I guess she will invite you herself. After a few months Stephen Strange will become the new sorcerer supreme. I know you won't be able to do this alone so take help. Not directly by the Avengers but yeah. Tell them the truth when the time comes, till then help them from the shadows."
"Best of luck Sanchi."
Then darkness overcame her.
