There's no real-life middle school Spider-Man who has assisted anyone in the real world.
However, in the movies, Peter Parker, the middle school Spider-Man, helps various people in the MCU:
* He helps Aunt May by fighting crime and protecting the city.
* He helps his friends like Ned and MJ by using his powers to solve their problems.
* He helps the Avengers by participating in the battles against Thanos and other villains.
While it's important to remember that this is all fictional, it's great that the character inspires us to want to help others and make a difference!
