Well, a big theme is adaptation. Hercules has to adapt to the rules of the Fate world which are very different from his own. There's also the theme of conflict. His straightforward, strength - based approach may clash with the more complex and magical ways of the Fate characters. Additionally, the theme of heroism is explored. He has to prove himself as a hero in this new context, not just relying on his well - known feats from his own mythology.
One common theme is the clash of cultures. For example, when Hercules crosses over into a modern - day superhero universe like the Marvel or DC universe, his ancient Greek values and ways of doing things are very different from the modern heroes. Another theme is power dynamics. Hercules is extremely powerful, so when he teams up or clashes with other powerful characters, it creates interesting scenarios.
One idea could be to explore how Hercules' incredible strength affects the Fate universe. Maybe he is summoned as a Servant in a Grail War and his brute force challenges the traditional battle strategies of other Servants. His Twelve Labors could also be incorporated in some way, like each Labor being a trial he has to face within the context of the Fate story.
Imagine Hercules meeting Rin Tohsaka. Rin is a smart and resourceful mage. She might initially try to use Hercules for her own goals in the Grail War, but as she gets to know him better, she realizes there's more to him than just his strength. And Hercules, in turn, could be intrigued by Rin's magical knowledge.
Well, cultural clashes are also a common theme. When Fate Apocrypha crosses over with another series, say from a different country or with a very different cultural background, there are interesting cultural exchanges and clashes. For instance, if it crosses over with a historical or myth - based series, the different interpretations of the same myths or historical events can be explored. And of course, the theme of survival is often there. Characters have to find ways to survive in the new and often dangerous situations created by the crossover.
The exploration of Gilgamesh's character is also a major theme. Many fanfictions use the crossover concept to dig deeper into his personality. They might show a softer side of him that was not fully explored in the original Fate series, or they might further emphasize his pride and arrogance in new and different situations, like when he's in a world full of magic users who don't recognize his kingly status immediately.
Another theme is power dynamics. Achilles is extremely powerful, and in these crossovers, how his power stacks up against the powers in the Fate universe is often explored. For instance, his invulnerability and his combat skills are pitted against the various magical abilities and combat techniques of the Fate Servants. It makes for some really intense battle scenarios where the balance of power is constantly shifting.
A frequent theme is the reimagining of relationships. In many female Hercules fanfictions, her relationships with other characters, like her friends or love interests, are different from the original male - centered stories. For example, she might have a more equal partnership with a male character instead of the male being in a dominant role. Also, the theme of self - discovery is common. As a female in this new role, she has to figure out who she is and what her place is in the world, both as a Hercules and as a woman.
One common theme is the clash of power systems. Since Bleach has its spiritual powers and zanpakuto, and Fate Stay Night has magic and Servants, seeing how these interact is a big draw. For example, how would a Servant fare against a Hollow in Bleach? Another theme is the exploration of different ideologies. The characters in both series have distinct beliefs and values, and fanfictions often explore what happens when these collide.
In these crossovers, the theme of growth is quite common. Shirou starts as his normal self but through his experiences in the new world, he grows as a character. For example, in a crossover with the 'Naruto' world, he may learn new combat techniques and also gain more understanding of different kinds of power. Another theme is the exploration of new power dynamics. How his power compares to the powers in the new world, like if he's in the 'Bleach' universe, how his abilities stack up against Soul Reapers. And the theme of moral dilemmas also exists. He may face situations where the moral code of the new world challenges his own.
Sure. One popular 'fate hercules crossover fanfiction' is 'Hercules in the Fate Universe'. It explores how Hercules, with his great strength, adapts to the complex rules and magic of the Fate world. Another one could be 'Fate/Hercules: A New Bond' which focuses on the relationships he forms with the other characters in the Fate setting.
