The relationships would be completely different. Instead of the usual friendships and rivalries, there would be a lot of hostility. For example, his relationship with Bakugo would be even more strained. Normally, there's a complex dynamic between them, but with Izuku hating everyone, it would be all - out enmity.
Another aspect could be the general discrimination in the BNHA society. The fact that society is so focused on quirks and those without are often looked down upon might have made Izuku bitter. He could be hating everyone because he sees the society as a whole being corrupt and unkind, not just the individuals who directly wronged him.
In fanfics, an emotionless Izuku can change the story a great deal. For instance, his decision - making process is different. He doesn't act out of anger or excitement like the regular Izuku. This can lead to different battles and outcomes.

Obviously, he would interact with his younger self. His younger self is a key character as Izuku from the future tries to guide and influence him. Also, All Might is likely to be an important character he interacts with. All Might has a huge influence on Izuku in the original story, and in the past, Izuku could have a different kind of interaction with him, perhaps sharing future knowledge about threats to hero society. His mother would also be someone he interacts with, as she is an important part of his life.
In 'bnha izuku detective fanfic', it's interesting because it often explores the underbelly of the hero society. Izuku, as a detective, might uncover things that the heroes don't see. For example, he could be investigating cases related to the illegal use of quirks or the seedy side of quirk trafficking. This gives a different perspective on the BNHA universe and keeps readers hooked as they discover these hidden aspects along with Izuku.
Well, a 'bnha grim reaper izuku fanfic' would likely revolve around Izuku Midoriya taking on characteristics of a Grim Reaper within the universe of My Hero Academia. This could mean that he has some sort of connection to death or the afterlife. For example, his quirk could be something that allows him to reap the'souls' of defeated villains, not in a literal sense but more of a metaphorical one where he takes away their will to continue being evil. Or perhaps he can see the life - force of people and use that knowledge to predict their actions in battle.
A fanfic with Izuku having a sand quirk could explore his new power dynamics. He would have to adapt his fighting style completely. Instead of using his original strength - based moves, he'd rely on the versatility of the sand. He could potentially use the sand to travel, like surfing on it. His relationship with other characters might also change. For instance, Bakugo might be even more envious of this unique quirk. And Izuku would have to learn how to use it subtly, perhaps by creating small sand particles to gather information without being noticed.
One of the best elements is often the enhanced character of Izuku. He's made to be even more determined and cool - headed. For example, in some fanfics, he has a quicker grasp of his powers, which makes him seem more in control and thus cooler. Another great element is the new relationships or the twists in existing relationships. Maybe Izuku forms an unexpected alliance or has a different kind of rivalry.
These fanfics are special as they allow for a lot of creativity. Writers can explore different scenarios that wouldn't be possible in the original BNHA plot. For example, if the 'one ounch' is a time - limited power, it can create high - stakes and exciting situations. Also, it can show a different side of Izuku, perhaps a more confident or experimental side that we don't often see in the main story.
