A 'naruto protection squad fanfic' is likely a fan - created fictional work centered around a group dedicated to protecting Naruto. It could involve unique storylines, new characters added to the Naruto universe for this purpose, and various adventures where they fend off threats against Naruto.
Often, you'll find characters who have a personal connection to Stark. Maybe a former employee of Stark Industries who has a deep sense of loyalty and joins the protection squad. Another could be a superhero friend of Stark's who decides to help out with the protection efforts. There might also be a character who was saved by Stark in the past and is now determined to return the favor by being part of the squad.
One interesting story could be about the squad preventing a super - villain from stealing Stark's latest technology. They use their unique skills and teamwork to outwit the bad guy.
His friends would probably take care of him. Midoriya would be very eager to help, using his kind-hearted nature. He would make sure Todoroki is fed and comfortable.
One idea could be that all his friends at UA plan a surprise birthday party for him. They decorate the common room with his favorite colors, blue and red. Another plot could be Todoroki spending his birthday with his family, trying to reconcile with his father on this special day. Maybe he receives a heartfelt gift from his mother that has a deep emotional significance.
Todoroki's character development in time travel fanfictions can be quite profound. He may start as a somewhat aloof character, but through time travel, he begins to understand the importance of relationships more deeply. When he travels back and witnesses the relationships he could have had or lost, it makes him cherish the ones he has in his original timeline. His view of heroism also evolves. He realizes that being a hero isn't just about using his powers but also about making the right choices at the right time, which is especially highlighted when he has to make decisions that could change entire timelines.
