I'm not sure which specific 'fat jake long story' you are referring to. There could be many stories involving someone named Jake who is fat. Maybe it's a story within a particular community, family, or even a fictional tale in a book or movie that I'm not familiar with.
Most likely not. Jake Long is a character that usually has adventures in a more action - oriented and age - appropriate context. Diaper - related stories about him would seem rather odd and not in line with the typical Jake Long narrative, so it's not something that would be easily found as a kid - friendly story.
One popular Jake Long and Rose love fanfiction could be 'The Unlikely Bond'. It explores their relationship in a world where they have to overcome various magical challenges together. Another might be 'Love Beyond the Dragons', which delves deep into their feelings as they face opposition from their different worlds. There's also 'Jake and Rose: A Forbidden Love', which focuses on the obstacles in their relationship due to their different natures.
A common plot is their struggle to be together despite their opposing roles. Jake is a dragon and Rose is a Huntsgirl after all. Another one could be them teaming up against a common enemy, which then deepens their bond.
There's also a possibility that Jake is just an ordinary person in the fanfiction world who has been given this extraordinary ability to imprint. This could make his character development really interesting as he has to deal with the consequences of this sudden and powerful connection to the reader. He might struggle with understanding his new feelings and how to act on them in a world that may not be used to such a thing.
The most popular characters are likely Danny and Jake for obvious reasons. But some of the villains also get their share of popularity. In Danny Phantom, Vlad Masters, with his complex relationship with Danny and his own set of powers, can be a fascinating character to write about in fanfiction. In Jake Long, the Huntsman, a formidable foe for Jake, can also be a popular choice. Writers often explore their motives and backstories, and how they might interact with the heroes in different situations.
One interesting storyline could be Danny and Jake teaming up to fight a common supernatural enemy that neither could handle alone. For example, a powerful ancient spirit that threatens both the human and ghost worlds in Danny's case, and the magical world in Jake's. Another could be a crossover where they end up in each other's universes and have to adapt to the new rules and powers while trying to find a way back home.
I don't really know the 'fat jake long story'. It could be anything. Maybe Jake is a character in a local legend and his 'fatness' is a key part of the story.
One interesting crossover could be the use of magic in Jake Long's world. For example, Harry Potter's spells might be used to solve some of the problems that Jake faces in his dragon - protecting duties. Maybe a spell to hide a dragon from the wrong eyes or a charm to communicate with the magical creatures in Jake's world more effectively.
