His relationship with All Might could also be affected. All Might might see Izuku as an even more special student. Izuku's healing ability could be something that All Might didn't expect, and it could make All Might even more proud of him. Also, Izuku could use his healing to help All Might with any lingering injuries from his hero days, strengthening their bond.
Well, with Bakugo, it would be a big change. Usually Bakugo is so used to Izuku's vocal reactions. But with Izuku mute, Bakugo might start to feel guilty for all the times he shouted at him. He could also start to respect Izuku more as he sees him overcome this new obstacle. For Ochaco, she would probably be one of the first to try and learn sign language to communicate with Izuku better, strengthening their bond.
Well, it makes it a lot more challenging. He has to rely on different skills. For example, he can't just see an opponent's attack coming like before. He has to use his sense of touch more, like feeling the air currents change when someone is about to strike.
In certain fanfictions, the izuku system is a secret. This secrecy can strain his relationships as he has to constantly lie or be evasive about his sudden improvements.

Well, his relationship with Bakugo would likely change a great deal. If Izuku is not human, Bakugo might view him as even more of an oddity or a threat. Instead of just seeing him as a rival with a quirk, he could be more hostile or overly cautious around Izuku.

When Izuku has a mythical quirk in fanfiction, say a power to transform into mythical creatures, it can change how others perceive him. His classmates might be in awe or a bit scared at first.

In a fanfiction where Izuku's system quirk is very powerful, it could lead to some characters feeling inferior. However, his closer friends like Ochaco or Iida might see it as an opportunity for all of them to grow. They could train with Izuku to better understand his quirk and improve their own skills. On the other hand, villains would likely target him more, which could put a strain on his relationships as he tries to protect those around him from the danger his quirk attracts.
Well, in some fanfictions, Izuku's transmutation quirk makes his friends view him as more of a valuable asset.
