[Western Crossover] Marvel: Third Playthrough

[Updated whenever inspiration strikes, heh.] Luo Xiaosheng, female, died tragically at the age of nineteen. After her death, for reasons unknown, she was chosen and bound by the System. As one of twelve transmigrators, she got unlucky and transmigrated into the body of two-year-old orphan Luo Na. Her mission was to gather all the Infinity Stones within thirty-five years and attain the title of Goddess of Vengeance. Luo Xiaosheng: ...This is so hard. On her first run, she went to school nervously and worked diligently, only getting her chance to shine during the Battle of New York. Later, she joined the Avengers as a reservist. However, after surviving Avengers: Infinity War and making it to Avengers: Endgame, she failed her mission. At the end of year thirty-four, the timeline was "mysteriously" reset. On her second run, at the tender age of four, she saved the Howard couple. At eight, she joined S.H.I.E.L.D. through Nick Fury, aka Black Egg (you). She took on Hydra and kicked every other villain to the curb. For over a decade, she gave her all and got the job done, eventually joining the Avengers alongside her coworkers Black Widow and Hawkeye. But in the end, the dusting in Avengers: Infinity War and the time travel in Avengers: Endgame turned thirty-four years of effort into nothing. Her unfinished mission and the heroes and comrades she could not save drained all the color from her world. Facing the Captain who had chosen to grow old, she smiled through her tears and said, "I'm sorry. I don't want to be a hero anymore." And so, the third run. The most inscrutable and greatest villain in history suddenly emerged. This time... what will the ending be? An announcement has been posted. Theme: Growth and rebellion
