Friendship is a very common theme. Their unique bond, where Shrek is the big, gruff ogre and Donkey is the chatty sidekick, is often explored in different ways. Another theme is adventure. Since they often go on adventures in the original movies, fanfics might continue those adventures or create new ones for them. Also, acceptance is there, as Shrek has to accept Donkey's presence and Donkey has to accept Shrek's ogre - ish ways.
Friendship is a very common theme. Just like in the movie, fanfictions often explore how the unlikely friendship between the dragon and donkey grows and deepens. For example, they might face challenges together and through that, their bond becomes stronger.
One great piece of Shrek dragon and donkey fanfiction is 'The Unlikely Friendship Extended'. It delves deeper into how the dragon and donkey's relationship evolves over time. They go on adventures together outside of what we see in the movie, like exploring new lands filled with magical creatures that are both friendly and hostile.
One popular 'Shrek x Donkey fanfic' is 'The Unlikely Bond'. It explores their friendship in more depth, showing how they support each other through various adventures in the swamp. Another is 'Shrek and Donkey's New Quest' which takes them on a journey to find a magical flower that can make the swamp even more beautiful. There's also 'Donkey's Insights' which is mainly from Donkey's perspective, sharing his thoughts about his friendship with Shrek.
I'm not sure exactly as it might be a very specific or even fan - made story. But generally, in the Shrek series, Shrek goes through various adventures, often dealing with his relationships and his identity as an ogre. Maybe in this part 3, he could face new challenges in his marriage with Fiona, or new threats to his home in the swamp.
Kind of. Shrek shows a unique take on love, with the characters overcoming obstacles and discovering their feelings for each other in an unconventional manner.
Well, if it follows the pattern of the Shrek series, Shrek himself would be a main character. And of course, Fiona, his wife. Donkey and Puss in Boots would likely also be main characters as they are Shrek's closest friends.
