One common theme is power - up. The OC often goes through various training or encounters that lead to new power levels, similar to how Saiyans do in the original series.
A really interesting plotline could be about the discovery of the connection between Fanalis and Saiyan powers. Maybe there's some ancient prophecy or hidden knowledge that links the two species. The story could then follow the characters as they uncover this mystery and what it means for their respective worlds. There could also be a plotline where a group of Fanalis and Saiyans team up to face a common enemy that threatens both of their existences, leading to some epic team - up moments and character development as they learn to work together.
A Harry Potter Saiyan Warrior fanfiction could be really interesting. Imagine Harry Potter having Saiyan powers. He could use his Ki to enhance his magic, like shooting a super - powered spell with the energy of a Kamehameha. It would completely change the dynamics of his battles against Voldemort and his Death Eaters. He could also train like a Saiyan, doing intense physical workouts to increase his power level, which would be a new concept in the wizarding world.
A great concept for a Super Saiyan crossover fanfiction would be to cross it with the Harry Potter world. Imagine a Super Saiyan wizard or witch. They could use magic spells while in their Super Saiyan form. Or perhaps a crossover with the God of War series, where the Super Saiyans fight alongside Kratos against the gods of that universe.
In a crossover with the 'Star Trek' universe, the Borg could be great antagonists for a godlike Saiyan. The Borg's collective intelligence and adaptability would pose a serious challenge to the Saiyan's power. Another option could be the Daleks from 'Doctor Who'. Their single - minded determination to destroy all non - Dalek life forms would put them at odds with the Saiyan.
For a 'godlike saiyan crossover fanfiction', a crossover with the Marvel Universe would be exciting. Picture a godlike Saiyan arriving on Earth during the events of 'Avengers: Endgame'. They could help the Avengers in their fight against Thanos. Their super - strength and energy - blasts could turn the tide of the battle. Or perhaps a crossover with the 'Lord of the Rings' world. The Saiyan could be a powerful ally in the fight against Sauron, using their speed and power to take on the orcs and other dark creatures.
Another interesting concept is to cross them over with a fantasy world. Saiyans could be in a world full of magic and mythical creatures. Picture Vegeta having to deal with dragons that can talk and cast spells. Their Saiyan pride might get in the way at first when they realize that their brute strength isn't always enough in this new world.
First, know your Saiyan lore well. Understand their abilities like Super Saiyan forms and their battle - hungry nature. Then, research the other universe you're crossing with. If it's a 'Saiyan x Star Trek' crossover, know about the Federation, the technology, and the alien races in Star Trek. Next, create an interesting plot that combines the two worlds. Maybe a Saiyan gets stranded on a Star Trek ship and has to learn their ways while still using his Saiyan powers.
Another concept could be a Saiyan - Naruto hybrid. A character who has both the natural talent for ninjutsu like Naruto and the raw power of a Saiyan. This character could struggle with balancing the two different power sources and cultures. They might face discrimination from both the Saiyan and ninja communities until they prove themselves as a unique and powerful force.
Another aspect to consider is how the Super Saiyan transformation would affect the relationships in the Naruto world. If Sasuke were to gain Super Saiyan powers, it could either drive him further away from Naruto due to the newfound power or bring them closer as they explore the new abilities together. Also, the concept of ki from Dragon Ball and chakra in Naruto could be merged, creating a whole new type of energy for the characters to utilize.
