His Slytherin friends like Blaise Zabini and Pansy Parkinson could be important characters. They might be in a difficult position. Do they try to help Draco despite the potential risks? Or do they abandon him? Another character could be Dumbledore. He often has a broader view of things and might see Draco's chained state as an opportunity for him to change. He could offer guidance or be the one to set certain events in motion regarding Draco.
Well, Ginny might interact with Draco if he's a maid in the fanfiction. She's a strong - willed character and her response to Draco in this new role could range from amusement to irritation. Another character could be Ron. Ron has always had a bit of a feud with Draco, and seeing him as a maid might bring out different reactions from Ron, like teasing or even a bit of begrudging respect if Draco does his job well. And of course, the other Slytherins might interact with him too. They could be embarrassed by his new position or try to help him depending on their individual personalities.
Draco would surely interact with the Dursleys. Vernon would probably be very suspicious and hostile towards Draco at first, seeing him as another strange and magical being. Petunia might be a bit more reserved but also curious in her own way. Dudley could range from being intimidated by Draco's wizarding background to being fascinated. And don't forget about Hedwig! If she's still around, Draco might have some sort of interaction with the owl, which could be really funny or interesting as he tries to figure out how to deal with this magical creature in the Muggle - dominated Dursleys' household.
Obviously, Draco is the central figure in 'draco's chains fanfiction'. But it's possible that original characters created by the fanfiction author are also main characters. They could be characters who have a special connection to Draco and the chains, like a mysterious figure who holds the key to his chains or a new love interest who helps him break free from whatever the chains represent.
Often, power dynamics play a big role. Draco, being bound, is in a position of weakness. This can lead to themes of vulnerability and how he copes with it. Some fanfictions may also focus on the mystery behind his being bound in chains. Was it a punishment? A spell gone wrong? Unraveling this mystery can be a major theme. And of course, there's the theme of hope. Despite his chained state, there's always the hope of liberation, both physically and metaphorically.
The other Slytherin students are very likely to be involved. Some might side with Draco, while others might see his punishment as an opportunity to gain power within the Slytherin hierarchy. Pansy Parkinson, for instance, might react in different ways depending on her relationship with Draco at the time of the punishment.
One character could be a Muggle schoolteacher. Draco might enroll in a Muggle school to blend in, and this teacher could take an interest in him. They could have conversations where the teacher tries to understand Draco's 'different' background (without knowing he's a wizard, of course). Another could be a Muggle mechanic. If Draco has some issues with a Muggle vehicle or machinery, he'd interact with the mechanic, and it would be a funny and challenging situation for him as he tries to understand how non - magical machines work.
The main antagonist could be a group of dark wizards who are trying to revive an ancient and powerful dark magic. They believe that Draco has some information about it because of his family's past associations. So they chain him up to force him to talk. This group could be led by a mysterious figure who has a personal vendetta against the Malfoy family.
Hermione might be one of his allies. Despite their past differences, they could put aside their grudges for the greater good of the Horcrux hunt. Also, Neville could potentially be an ally. Neville has shown great courage and determination, and he might see Draco's newfound willingness to fight against Voldemort as a sign of change.
Obviously, Draco Malfoy and Dudley Dursley are the main characters. Draco, with his blond hair and aristocratic air, is a well - known Slytherin from the Harry Potter series. Dudley, on the other hand, is Harry's cousin, a rather large and spoiled Muggle boy. Their encounter would be the central focus of this fanfiction.
Harry Potter and his friends could be important characters as well. Their relationship with Draco could be explored in different ways. Maybe they start to see Draco in a new light and begin to trust him a little more. Hermione Granger, with her intelligence and strong moral compass, could play a role in Draco's redemption or self - discovery journey.
