No, it doesn't seem appropriate. Fanfiction is a form of creative writing that often involves exploring characters in new ways, but this description crosses the line into something that is more likely to be offensive or inappropriate. It goes against the general spirit of positive and respectful fan - created content. Fandoms are meant to be inclusive and family - friendly spaces in many cases, and this kind of theme doesn't fit well into that.
I'm not sure where you can specifically find a 'naked crawl leash Draco' fanfiction. Fanfiction websites like Archive of Our Own (AO3) or Fanfiction.net might be good places to start, but you'll have to search using relevant tags and keywords carefully. Some works might be restricted due to their rather unusual or potentially inappropriate themes.
No, it's not a common element. While Hogwarts fanfiction can cover a vast range of themes and ideas, the concept of a 'Draco Leash' is rather unusual and not something you'd typically find in mainstream fanfics.
Draco can be developed by showing his vulnerability during the naked crawl. His pride is usually a big part of his character, so this situation would force him to face his insecurities. For example, he might be worried about what others think of his physical appearance. Also, his resourcefulness can come into play as he tries to find a way to end the situation or at least cover himself up.
Well, in fanfiction, authors often take creative liberties. 'Draco Leash' might be part of a strange or alternative plotline. It could be related to a power dynamic within the Hogwarts setting. For example, if it's a dark or AU (alternate universe) fanfic, perhaps a character has some sort of magical or non - magical leash on Draco to keep him in line or for some other more sinister purpose. And the 'naked' part might just be added for shock value or to add an element of sensuality or vulnerability to the situation.
There's a fanfic I once heard about where Draco is in a sort of magical punishment situation that involves crawling and a leash - like magic. But I can't recall the name. You might have to dig deep into the fanfiction archives. Try looking for ones with unique and edgy concepts related to Draco's character transformation.
Rather than focusing on potentially controversial themes like 'naked crawl collar', it would be better to look for Draco - centric fanfiction that focuses on positive character development, his relationships in a more appropriate context, such as his friendships or his journey to redemption. There are many great Draco fanfictions out there that explore his complex character in a tasteful way.
One plot idea could be Draco having to do a naked crawl as a part of a dare in a magical forest. Maybe he's trying to prove his bravery to his Slytherin friends. Another could be in an alternate universe where it's a rite of passage in a wizarding cult that Draco is unknowingly a part of. A third idea is that it's a curse placed on him by a rival, and during the crawl, he discovers secrets about the magical world around him.
There are fanfictions that focus on Draco's inner turmoil and growth. This could involve his struggle with the expectations placed on him by the Slytherin house and his family. He might question the pure - blood ideology and strive to be a better person. Another theme is his love interests that are presented in a more chaste and emotional way, rather than any improper or adult - themed relationships. Some fanfictions also explore his magical abilities and how he uses them for good or self - improvement.
One possible fanfiction could be about a magical creature Draco that is tamed and put on a leash by a powerful wizard. The wizard might be using Draco for some sort of mission, like exploring a dangerous enchanted forest. Draco could be a dragon - like creature with its own will, and throughout the story, it struggles against the leash both physically and emotionally as it tries to assert its independence.
