Another plot could involve a crossover with a post - apocalyptic anime. Garo finds himself in a world that has been destroyed, and he teams up with the survivors. They have to face not only the typical threats of the post - apocalyptic world like raiders and lack of resources, but also a new form of evil that has emerged from the chaos, something that only Garo's skills can help combat.
One great character to include could be Naruto from 'Naruto'. His determination and his powerful ninja skills would make for an interesting dynamic with Garo. He could teach Garo some of his ninja techniques, and Garo could in turn show Naruto how to deal with darker, more demonic threats.
One popular 'garo crossover fanfiction' story could be the one where Garo crosses over with another well - known fantasy series. It might involve Garo teaming up with characters from that series to fight a common enemy. For example, if it's a crossover with a magical girl series, Garo could bring his unique combat skills while the magical girls use their magic, creating an interesting dynamic.
One idea could be a time - travel plot. The Running Man characters could be sent back in time to the origin of the game show and have to compete in the very first, more primitive version of the challenges. Another idea is a crossover with other popular anime characters. They could team up or compete against characters from Naruto or One Piece, for example.
Maybe a crossover with a magical anime. The nanbaka characters could suddenly find themselves in a world full of magic. Some of the nanbaka characters might be really good at using magic in unexpected ways, like Jyugo using his shackles in a magical battle.
A crossover with a modern - day action story could be really cool too. Spartacus and his crew could be brought to the present day through some time - travel mishap. They then have to navigate the modern world, learning about new weapons and technology. They could use their ancient fighting techniques in modern combat situations, like taking on a powerful criminal organization.
Maybe in the fanfiction, the three - tailed beast crosses over into a modern - day human world. People initially fear it, but then they discover that it has a gentle side and is actually trying to find its way back home. It could form a bond with a group of humans who help it on its journey, leading to many adventures along the way.
One idea could be a crossover with 'Fullmetal Alchemist'. Dorohedoro's dark and gritty world combined with the alchemical concepts would be fascinating. For example, the characters from Dorohedoro could be exposed to the laws of equivalent exchange. Another plot could involve a crossover with 'Hunter x Hunter'. The nen abilities in 'Hunter x Hunter' could interact in strange ways with the magic in Dorohedoro's world. Maybe a character from Dorohedoro has to participate in the Hunter Exam. A third idea is a crossover with 'Tokyo Ghoul'. The idea of the ghouls' existence in Dorohedoro's setting and how they would coexist or clash with the existing creatures and characters there.
One idea could be a Vegito crossover with the Dragon Ball GT universe. Vegito could face off against the Shadow Dragons, creating an epic battle of power. Another could be a crossover with the One Piece world, where Vegito has to navigate the Grand Line and deal with pirates. Maybe he teams up with the Straw Hats to take on a common enemy.
One idea could be a crossover with the 'Indiana Jones' series. The Mummy's curse could somehow be related to an ancient artifact that Indiana Jones is after. Maybe they have to team up to stop the mummy from unleashing a greater evil.
One idea could be a crossover with another popular space - themed series. For example, the Kyurangers could meet the crew of a well - known starship. They could team up to fight a common enemy that threatens both their universes, like an intergalactic pirate group. This would bring together different technologies and fighting styles.
