Who could be the antagonists in a 'Harry and Ginny baby Lily' fanfiction?

One possible plot could be that the baby Lily shows signs of having extraordinary magical abilities from a very young age. Harry and Ginny are both proud yet a bit worried about how to guide her. Maybe she accidentally makes things levitate or changes the color of her nursery walls with her magic. They start to introduce her to the wizarding world gently, taking her to visit Hagrid at Hogwarts. And as she grows, they face challenges from the wizarding community who are either overly curious or a bit envious of the family's status.

In the 'Harry and Daphne baby fanfiction', it could be a new dark wizard who rises to power.

Voldemort could be an antagonist if he somehow returns and sees the baby as a threat or a symbol of a new hope that he wants to destroy. He might target the baby to get back at Harry and Tom.
