Another aspect is the potential for character growth. Ponies that are used to a relatively calm life in the regular MLP story might have to face tough challenges in a 'man of war' scenario. This could lead to them developing new skills, such as combat skills or leadership abilities, which makes for an interesting read as we see them transform from their normal selves.
I'm not sure about specific 'man of war mlp fanfic' titles off the top of my head. But you can start by looking on popular fanfic websites like Fimfiction.net. There, you can use the search function and type in relevant keywords like'man of war' and 'MLP' to find stories that might match what you're looking for.
There's a fanfic called 'When Spider - Man Swings into Ponyville'. This one focuses more on the cultural shock that Spider - Man experiences in Ponyville. The way the author writes about his attempts to understand the pony way of life while also using his powers to help out in small ways is really engaging.
Often, Twilight Sparkle can be a main character. Given her intelligence and magical abilities, she might be in the forefront of trying to understand the crystals and end the war. She could be using her knowledge of magic to find solutions.
A good MLP and Spider - Man fanfic should have a well - developed plot. It can't just be a random combination of the two universes. For example, it could explore how Spider - Man's values of responsibility and heroism would play out in the MLP world. Maybe he'd teach the ponies some new ways to protect their land or he'd learn from their harmonious society.
In a fanfic, the ponies and God of War characters could also have a conflict at first. The ponies' values of harmony and love might be at odds with the God of War characters' thirst for vengeance and power. However, as the story progresses, they could find common ground. For example, they could both realize that there are greater threats that require their combined efforts. The ponies could use their magic to help the God of War characters in battles, while the God of War characters could protect the ponies from the more brutal aspects of their world.
One idea could be to have the ponies from MLP enter the world of God of War. They could team up with Kratos and use their unique magical abilities to fight the gods. For example, Twilight Sparkle's powerful magic could be used to counter some of the dark magic of the God of War enemies.
There could be a 'god of war mlp fanfic' where Kratos teams up with Twilight Sparkle. Imagine Kratos with his brute strength and Twilight with her magic working together to face a common enemy that threatens both their worlds. It would be a unique combination of the dark and gritty God of War style with the light - hearted MLP setting.
Another plotline might involve a young pony who has the ability to communicate with the crystals. This pony could then be caught in the middle of the war, with both sides trying to use their unique talent for their own purposes. They might struggle with loyalty and the right path to take.
There are likely fanfics where the mlp characters have to face the psychological terror that Slender Man usually brings. In these stories, the art style of My Little Pony might be blended with the dark and shadowy look of Slender Man. Some fanfics could explore how the different pony races, like Pegasi or Unicorns, react to the presence of Slender Man, whether they use their flight or magic to try and combat this otherworldly entity.
