A 'princesa caricatura' is typically a cartoonish or exaggerated representation of a princess. It might focus on highlighting certain features or personality traits for comical or artistic effect.
In terms of the plot, it could start with Sombra's return or some sort of threat that he poses. Luna then steps in to deal with it. The setting within the My Little Pony world would be important. It could be set in Canterlot or some other location. The fanfic might also introduce new characters or use existing ones to support the main plotline between Luna and Sombra.
Obviously, the princess would be one of the main characters. There might also be a charming prince or a dashing knight as the male lead. And there could be a scheming villain, perhaps an envious noble or a power - hungry courtier.
One interesting aspect could be its setting. It might be set in a grand, fictional kingdom which adds a touch of magic and allure. The characters in 'la princesa' are likely to be complex and well - developed, with the princess herself having a unique personality.
One common theme could be the battle between light and dark. Luna represents the moon and has an association with the night, which can be seen as a time of mystery and sometimes danger. King Sombra is a dark character. So the fanfic may explore this contrast in terms of their powers and personalities.
I'm not that familiar with her, but she must be the central figure in this story. Maybe she was someone who went through an extraordinary event related to judgment.
Ellie could be a new superhero in training. Maybe she has some sort of power related to energy manipulation. She looks up to Peter and Wade and wants to learn from them. So she gets involved in their adventures and gradually becomes an important part of their team.
Well, in a story like 'Ellie's Story: A Dog's Purpose Novel', apart from Ellie, the main characters could be the people she lives with. They would be the ones who take care of her, train her, and form a deep bond with her. There might also be some antagonists, like people or animals that pose a threat to Ellie or her family. This would add conflict to the story and help in exploring Ellie's purpose further.
