What are some interesting plot ideas for Gokaiger Crossover Fanfiction?

One possible plot is that the Lion Guard discovers some strange energy signatures that seem out of place in their world. These turn out to be related to the Gokaigers' power sources. As they try to figure out what's going on, the Gokaigers also detect a disruption in the balance of their power. They meet up and find out that a powerful enemy is trying to harness the combined power of both the Gokaigers' ranger powers and the magic of the Lion Guard's world. So, they have to put aside their differences and work together. The Lion Guard can use their natural abilities like Simba's roar, while the Gokaigers can use their mecha and ranger attacks to battle this new threat.

There could be a Gokaiger fanfiction that focuses on the backstories of each individual Gokaiger. For example, how they came to be chosen for the mission and what their lives were like before joining the team. This would give more depth to the characters and make the story more engaging.

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.

One idea could be that the Turtles from 2003 get transported to the 2012 universe and they have to deal with the different versions of their enemies. For example, the Shredder in the 2012 version might have some new powers or tactics that the 2003 Turtles aren't used to.
