all for one is deku's dad fanfiction

There are indeed. Some fanfic writers find the idea of All Might being Deku's dad an interesting twist. It can lead to some really heartwarming and intense storylines. For example, in these fanfics, All Might might have a more personal reason for choosing Deku as his successor, and Deku could inherit not only One For All but also some other traits or legacies from All Might in a more family - related way.

In 'All for One Deku' fanfiction, it's interesting to explore the new relationships Deku would form. For example, his interactions with villains who were once on the opposite side of him. Also, the power dynamics shift. Instead of being the underdog hero, he could potentially become a more complex and morally ambiguous character with All for One's powers. His internal struggle between his original self and the new, darker influence can create really engaging storylines.

In most of such fanfictions, they might create evidence like hidden past connections. For example, AFO could be secretly involved in Izuku Midoriya's (Deku) family history. Maybe he had a relationship with Deku's mother long ago, which led to Deku's birth. But it's all fictional speculation within the fanfiction world.

One common plot twist is that Deku discovers the truth about his father in a moment of great crisis. For example, when he's facing off against AFO in a big battle, AFO reveals the truth to him, which completely shakes Deku's world view.

Another could be Deku inheriting not just One For All but also some family heirlooms or special abilities from All Might's side of the family.
