Well, a significant theme is the anticipation of motherhood. It's about the pregnant pony's dreams and hopes for her future offspring. There can be a lot of focus on how she plans for the baby's arrival, like preparing a nursery or choosing a name. And sometimes, there are themes related to the relationship between the pregnant character and her partner, if there is one, like how they grow closer or face difficulties together during this special time.
The theme of change is also quite prevalent. The pregnant pony has to adjust to physical and emotional changes. In some fanfics, there's also the theme of facing challenges during pregnancy, such as dealing with difficult situations or unexpected events that test the character's strength.
One common theme is the idea of new life and the excitement it brings. The pregnant character often experiences a range of emotions from joy to fear. Another theme is the support of the community around the pregnant character, like how friends and family come together.
One common theme could be the idea of Fluttershy's friends supporting her during this new phase in her life. Another might be how Fluttershy adapts to the changes that come with being pregnant.
One common theme is the anticipation and excitement within the Ponyville community. It often shows how Twilight's friends support her during her pregnancy.
The theme of self - discovery is also common. Through their interactions with each other, both Fluttershy and Rainbow Dash may learn more about themselves. For example, Fluttershy might become more confident or Rainbow Dash might learn to be more patient. And of course, the theme of loyalty is there. They are loyal to each other, and fanfics often show how they stand by one another in difficult situations. This can be seen in many fanfics where one of them is in trouble and the other comes to the rescue without hesitation.
Overcoming differences is another big one. Ponies in MLP have different personalities, like Pinkie Pie's exuberance and Twilight's studiousness. Shipping fanfics often show how these differences can be bridged in a relationship. They might have to learn to understand and accept each other's quirks and ways of doing things. For instance, in some 'Twidash' (Twilight and Rainbow Dash) fanfics, Rainbow Dash has to understand Twilight's need for order in her studies while Twilight has to accept Rainbow Dash's daredevil nature.
A common theme is the clash of cultures. Since Naruto comes from a world of ninjas, full of combat and honor codes, and the MLP world is more about friendship and magic, seeing how these two different cultures interact is often explored. For instance, how Naruto's idea of loyalty is similar or different from that of the ponies.
Adventure is also a big theme. Toby goes on all sorts of exciting adventures in the MLP world. He might be exploring uncharted territories, facing magical creatures, or helping the ponies save their land from some sort of danger. These adventures make the fanfics really engaging and full of action.
One common theme is friendship. Since Sonata is part of the MLP universe, many fanfics explore how she forms and nurtures friendships. Another theme is self - discovery. Sonata often goes through a journey of finding out more about herself.
Recovery is also a big theme. The fanfics usually show the process of the ponies getting better, whether it's through the help of magic - infused medicine or just good old - fashioned rest and care. It can be quite inspiring to see how the ponies overcome their injuries or illnesses. For example, a pony with a broken leg learning to walk again with the help of crutches and the encouragement of friends.
A common theme is the clash of cultures. Bane, coming from his own dark world, enters the bright and friendly world of My Little Pony. So there's often a theme of how these two very different worlds and their values interact. Another theme is redemption. Sometimes Bane is portrayed as a character who can be redeemed through his experiences in Equestria.
One common theme is the clash of different natures. Vampires, with their dark and often predatory nature, contrast with the colorful and friendly world of My Little Pony. So there's often a theme of conflict and resolution. For example, how can the ponies deal with a creature that feeds on blood? Another theme is transformation. Sometimes a pony might be turned into a vampire, and the story explores how they adapt to this new form and how their relationships change.
