In an MLP - Coco fanfic, the pommel could be a magical object that has been cursed. It starts to cause chaos in both worlds, making ponies lose their magic and the characters in Coco's world forget their loved ones. A young and brave pony and a musically - talented character from Coco find out that they are the only ones who can break the curse of the pommel. They have to journey through both worlds, learning about each other's cultures and using their unique skills to find a way to cleanse the pommel and restore peace.
Perhaps the pommel is a lost artifact from an ancient time that has the ability to open portals between different dimensions, including the ones where MLP and Coco's worlds exist. A group of characters from both universes, led by Twilight Sparkle from MLP and Miguel from Coco, embark on a quest to find the pommel and control its power, facing many challenges along the way. They must overcome their differences and work together to keep the pommel out of the wrong hands.
There might not be a huge amount of such fanfics readily available. However, you could check fan communities and forums dedicated to MLP and Coco. Sometimes fans discuss and even share their own unpublished fanfic ideas or works related to rather specific topics like this. It's also possible that a pommel could be used symbolically in a story, perhaps as an important object in an adventure in an MLP - Coco crossover fanfic.
The fanfic could tell the story of how Nova Star and Sparkle first met. It could be a chance encounter in a magical forest where they both were drawn to a mysterious, glowing object. Their initial mistrust turns into friendship as they figure out the purpose of the object together.
One idea could be a Beezen character in the MLP world having to adapt to the magic there. Maybe they start off as an outsider and gradually learn to use the magic for good, like helping ponies build better hives or something.
One idea could be a wedding between two ponies from different tribes, like a Pegasus and an Earth pony. They would have to overcome the differences in their cultures and traditions. For example, the Pegasus might have a flying ceremony while the Earth pony has a more grounded celebration. Another plot could involve a wedding planner pony trying to create the perfect wedding but facing all sorts of comical disasters along the way, like the flowers not arriving or the cake getting ruined.
One idea could be to create a fanfic where Coco Bandicoot discovers a hidden, ancient power within the jungle. She then has to learn how to control it to save her friends from a new, powerful villain.
One idea could be that the ponies from MLP accidentally enter the Pokemon world through a magical portal. They team up with some Pokemon trainers to stop an evil team that's trying to use both pony magic and Pokemon power for their own bad deeds. Another plot could be a Pokemon tournament where ponies are allowed to participate using their unique abilities as if they were Pokemon. For example, a Pegasus pony could use its flying skills in a battle like a Flying - type Pokemon.
One idea could be that the ponies from different pony tribes are forced into the Hunger Games arena. For example, the earth ponies might use their strength and connection to the land to find food and build shelters. The pegasi could use their flying abilities to gain a strategic advantage in the arena, like scouting from above. And the unicorns could use their magic for various things like defense or creating illusions to mislead opponents.
One idea could be that Discord causes chaos in Equestria that the MLP characters have to solve in a really wacky way. For example, he might turn all the clouds into cotton candy and the ponies have to figure out how to make it rain again without making a huge mess. Another plot could involve Discord getting his powers mixed up with a unicorn's magic and they have to work together to undo it. Maybe he accidentally gives Twilight Sparkle the power to turn things into random objects every time she tries to use her normal spells.
Well, you could write about a time - travel plot in an MLP School of Friendship fanfic. For example, some of the ponies accidentally go back in time to when the school was first being built. They meet the founders and learn about the original intentions of the school. Or perhaps a story where a spell goes wrong and it makes some of the ponies swap personalities. They then have to figure out how to reverse the spell while also learning more about each other. And also, a story about a lost friendship diary that holds the secrets of the early days of the school, and the ponies go on an adventure to find it.
Well, a cool plot for an MLP Battle Force 5 fanfic could be that there's a strange energy wave that disrupts both the MLP world and the Battle Force 5 world. The ponies and the Battle Force 5 members start having strange abilities or problems because of it. They then have to figure out the source of this energy wave, which leads them on an adventure across both worlds. Along the way, they learn about each other's cultures and strengths, and in the end, they manage to stop the energy wave and become friends. It could also involve some of the ponies learning to drive the Battle Force 5 vehicles in a really funny way.
