One common plot is Snape trying to keep Draco out of danger during the Second Wizarding War. Since he has inside knowledge of both the Death Eaters' plans and Dumbledore's side, he uses this to protect Draco. For instance, he may prevent Draco from being given extremely dangerous tasks by Voldemort.
Another plot often seen is Snape mentoring Draco in magic in a more personal way than just as a teacher. He might pass on his own spells or techniques that he developed over the years. This helps Draco grow as a wizard and also strengthens their bond as godfather and godson. In these stories, Draco may start to see Snape as more of a father figure than Lucius.
A common plot also involves Snape dealing with the Malfoy family's expectations of Draco. As Draco's godfather, Snape has to navigate between what the Malfoys want for Draco (like maintaining their pure - blood status and loyalty to Voldemort) and what he believes is right for Draco. This can lead to a lot of family drama and interesting character interactions within the fanfiction.
A common plot is Snape trying to protect a werewolf from being hunted by other wizards. He might use his potions - making skills to create something that can hide the werewolf's scent or control their transformation. This shows his more compassionate side that we don't always see in the original books.
In some fanfictions, Snape as Draco's godfather can be portrayed as a very protective figure. He might use his influence in Hogwarts to shield Draco from various troubles. For example, he could ensure Draco gets preferential treatment in Potions class or intervenes when Draco gets into minor scrapes with other students. Snape's complex personality adds an interesting layer to this relationship. His loyalty to the Dark Lord on one hand and his newfound role as a godfather on the other create a great internal conflict for his character in these stories.
Often, there are plots where there is some sort of magical interference causing Hermione's labor complications. For example, a dark magic spell was cast on her. Draco, who has some knowledge of the dark arts, tries to reverse it. In some stories, the labor complications are a result of a prophecy that involves both of them. The two of them then have to figure out how to break the cycle and save Hermione and the baby.
In Draco Snape godfather fanfiction, it's possible to see a side of Snape that we don't often get in the original books. As Draco's godfather, he might share with Draco his love for potions in a more personal way. He could take Draco on secret trips to find rare potion ingredients, bonding over their shared interest. This would not only strengthen their relationship but also show a different aspect of Snape's character, one that is more nurturing and less brooding.
In some Draco Snape godfather fanfictions, the story might explore the idea of Snape protecting Draco from Voldemort's more extreme demands. Since Snape is a double agent, he has a unique position to keep Draco out of harm's way. He could train Draco in more defensive magic, rather than offensive dark magic. This would create an interesting dynamic between the two, as Draco tries to understand Snape's motives and Snape tries to keep his cover while still being a positive influence on Draco.
One common plot is Snape trying to hide Harry's identity from the dark forces while also training him in advanced magic. Another is Snape having to deal with Harry's rebellious nature against his strict guardianship. For instance, Harry might want to explore certain parts of the Forbidden Forest, but Snape forbids it for his safety.
One interesting fanfiction could be about how Harry, Snape and Draco's families interact in a post - war Hogwarts. Maybe Harry and Draco, now adults, are trying to make amends for their past enmity. Snape, through some magical occurrence, is brought back to life. His presence causes a stir as he has a complex relationship with both Harry's family (given his past with James Potter) and Draco's family. They all have to navigate through old grudges and new understandings.
A common plot is that Snape uses his position as a double agent to his advantage. He gets close to Voldemort and then at a key moment, he uses a hidden weapon or spell to injure him. For example, he might have a wand with special properties that he uses against Voldemort. This is popular because it plays on Snape's duplicitous nature.
One common plotline is a time - travel scenario. Hermione might go back in time and interact with a younger Snape, Lucius, and the others. This could lead to her trying to change the future, like preventing Draco from following in his father's dark footsteps. Another plotline could be a magical mystery where they all have to work together. For example, a powerful dark magic object is discovered, and Hermione teams up with Draco, Blaise, and Theo, while Snape and Lucius are reluctantly involved too. And there's also the plotline of a secret society where they are all members, with Hermione bringing a different ideology that challenges the pure - blood - centric views of some of the others.
One common plot is Iron Man competing in a high - stakes gaming tournament. He has to face off against powerful opponents using his suit's abilities and his own gaming skills.
