I haven't come across a particular 'fat slob draco fanfiction' myself. However, you can look for it in fanfiction communities. Maybe start by using relevant tags when you search. For example, if it's related to a specific series like Harry Potter (assuming Draco is from that), use tags related to both Draco and the series to narrow down your search.
I'm not sure specifically as there could be various interpretations. It might be a fan - made story where the character Draco is depicted in an unflattering way as a 'fat slob'. However, without reading the actual fanfiction, it's hard to say for certain.
I have no idea if it's popular. It could be popular within a small niche of fans who enjoy this kind of unorthodox take on the character, or it might not be well - known at all. There are so many fanfictions out there that it's hard to gauge the popularity of just one without proper research.
One possible theme could be self - discovery. If Draco is portrayed as a 'fat slob', he might go through a journey of realizing his own state and trying to change. Another theme could be social ostracism. People in the story might treat him differently because of his appearance.
One great 'fat draco fanfiction' could be 'The Larger Than Life Draco'. It explores Draco's character in a new light with this unique take on his appearance. It has interesting character development and some really engaging plot twists.
Maybe it could be about how Draco's slobbish habits annoy his friends or family in the fanfiction world. For example, he might leave his things all over the place in the Slytherin common room, causing chaos and getting into little squabbles with his housemates.
His father, Lucius Malfoy, might also be a main character. Lucius, who is always so concerned about appearances and family reputation, would be horrified by Draco's slobbishness. There could be a lot of conflict between them as Lucius tries to force Draco to be presentable again. And then there's Hermione Granger. Since she's always so neat and organized, she might be appalled by Draco's slobbish ways and get involved in some sort of rivalry or strange friendship with him because of it.
One anime that might have elements of this is 'Kaguya -sama: Love is War'. In some episodes, there are comical situations where characters might overeat in a slobbish way which could potentially lead to some weight gain implications. But it's not the main focus of the show.
One common theme is self - acceptance. Draco has to come to terms with his new body shape, which is often a journey of learning to love himself again. For example, in many stories, he initially struggles with how others perceive him but then grows stronger.
Well, 'A Different Sorting' is an interesting piece of 'draco in ravenclaw fanfiction'. In this story, Draco's personality takes on new dimensions as a result of being in Ravenclaw. The story focuses on his intellectual growth and his interactions with Ravenclaw housemates, which are quite different from what we'd expect in Slytherin. There's also 'Draco in Blue and Bronze' which has a really unique take on how his character develops in the Ravenclaw house.
There's 'The Adorable Side of Draco'. In this fanfiction, Draco is depicted as having a hidden soft side. He secretly helps out the other characters in the story without expecting anything in return. The author does a wonderful job of showing his vulnerability and kindness, which makes for an adorable read.
