Sirius would handle it with love and determination. He'd start by teaching Harry basic things like how to control his magic when he starts showing signs of it at a very young age. He'd also introduce Harry to the concept of good and evil in the wizarding world. Since Sirius has a bit of a rebellious streak, he might raise Harry to question the status quo in the wizarding world and think for himself. He'd be like a combination of a strict father and a fun - loving uncle, making sure Harry grows up happy and strong.
Sirius would probably be very protective. He'd use his magic to create a safe and comfortable environment for Harry. For example, he might conjure up soft, warm bedding for the baby. He'd also try to find the best baby - wizarding supplies, like magic - infused milk bottles that ensure Harry gets all the nutrition he needs.
Sheldon might try to apply scientific parenting methods. For example, he could create a strict schedule for the baby's feeding, sleeping, and learning based on research. Penny, on the other hand, would probably be more laid - back and focus on the baby's emotional needs, like cuddling and playing. Together, they would have to find a balance between Sheldon's rigidity and Penny's spontaneity.
Sirius could use his knowledge of the wizarding world's secrets. He might know some hidden places or spells that could keep Voldemort at bay. For example, he could put a powerful protective charm on the place where Harry is staying.
Well, Hermione would be a crucial character. She would be the voice of reason for Harry. She might research every possible magical solution to either understand the pregnancy better or find a way to reverse it if that's what Harry wanted. Ron would be more of a wildcard. He might be disgusted at first given his past issues with Draco, but eventually, he would probably come around to support his friend. As for Draco's friends, they could either shun him or support him depending on their own views on this very unconventional situation.
Loki is known for his mischievous and sometimes devious nature. This might lead to him teaching the baby some tricks that are not exactly 'by - the - book'. Valkyrie, on the other hand, is strong - willed and brave. She would likely instill a sense of courage in the baby. So the baby might grow up with a unique blend of playfulness and fearlessness.
The 10th Doctor's compassion and curiosity could have a profound impact on Naruto's development. Maybe he'd introduce Naruto to new worlds and concepts, expanding his horizons.
Sirius would probably be very worried and immediately try to help Harry. He might use some basic healing spells he knows.
Well, their relationship would be in tatters. Harry would probably avoid Sirius like the plague after such an event. Sirius, on the other hand, would be at a loss for how to deal with what has happened. He might feel betrayed, even though he knows Harry was forced. This would create a huge rift between them that would take a lot of time and effort, if ever, to mend. It would also change the way they interact with other characters in the fanfiction, as their relationship was an important part of the overall story dynamic.
Sirius would have a big impact on Harry's understanding of family. Harry has always longed for a real family, and Sirius would show him what a loving and supportive family can be like. This would make Harry more open - hearted and less guarded. He would also be more likely to forgive those who have wronged him in the past, as Sirius might teach him the value of forgiveness. Moreover, Sirius' love for adventure could make Harry more adventurous in his exploration of magic and the wizarding world.
There's a fanfic called 'Padfoot and Moony's Little Cub'. In this one, Sirius and Remus raise Harry in a cottage hidden from the wizarding world. Harry grows up learning about his parents from the two men who knew them best. It has some really heartwarming scenes where they celebrate Harry's birthdays and teach him about the Marauders' adventures.
It could potentially strain the relationship. If Sirius misinterprets the situation, it might create some tension. Harry and Hermione would feel like they need to explain themselves, and Sirius might be a bit standoffish until he gets the real story. For instance, if he thought they were hiding something from him, it could make things a bit rocky between them for a while.
