There could be a lack of resources within the team. Maybe they simply don't have enough time or manpower to deal with all the fanfiction out there, and Tony fanfiction unfortunately gets neglected. Another possibility is that there is some internal politics or bias within the team. If certain members don't like Tony as a character, they might influence the team to neglect the related fanfiction.
It could be that the Tony fanfiction doesn't align with the team's vision or values. For example, if the team is trying to create a certain image or brand, and the fanfiction goes against that in some way, they would neglect it. Also, if the fanfiction has a lot of inaccuracies or goes too far from the original source material regarding Tony, the team might choose not to give it any attention.
He might just be a big fan of Loki himself in the fanfiction world. So, he wants to protect the stories that feature Loki.
Fanfiction sometimes goes against the essence of the original characters. Sakura, being a strong - willed character, might not want to be part of the Team 7 fanfiction where her character could be misused. For instance, she could be made into a weak or overly emotional character in fanfiction, which is not true to her original self. Also, the relationships within Team 7 in fanfiction might be warped in ways that she finds unacceptable, like false romances or rivalries that don't exist in the original story.
They might love it because it gives them new and different storylines. In fanfiction, they can experience things not in the original plot.
Tony could be the team captain. As the captain, he has a special bond with the team members and might want to do something special to boost their morale. He would know what kind of surprises would really make an impact on them.
Their relationship would be a slow - burn. Loki might play some pranks on Tony at the beginning, which would annoy him. However, when they get into a really tough situation, like being trapped in a dangerous dimension, they have to rely on each other. Loki could use his magic to keep them alive, while Tony uses his engineering skills to find a way out. This shared experience would bring them closer and make them realize that they can be good partners.
It's possible that Tony wants to control the narrative. By protecting the fanfiction, he can ensure that the stories about his AIs are in line with his values and goals for the technology. Also, protecting fanfiction can attract more people to be interested in his AIs, as it shows a positive and inclusive attitude towards the fan community.
It could bring them closer. By reading and discussing Tony fanfiction, they'll be focusing on a common interest related to one of their own. This shared experience can enhance their sense of unity.
One reason could be that Naruto is a character with his own identity and goals. If the fanfiction keeps putting him in situations that are not in line with his character arc, such as making him abandon his dreams for the sake of Team 7 in a way that doesn't make sense, he would have enough. Fanfiction writers sometimes go overboard with their creativity and end up straying too far from what Naruto is really about.
Another possibility is that he underestimates the importance of family. Tony has always been focused on his own achievements and the big - picture stuff. He might not realize how much his daughter needs him until it's too late.
Maybe he's too caught up in his work. Tony Stark is often depicted as a workaholic, so he could be so focused on his inventions and saving the world that he simply doesn't have time for his son.
