Well, in such a fanfiction, the Gate of Babylon could be used as a training ground for Naruto. He could face the various challenges presented by the treasures and entities within the Gate. This would not only strengthen his physical abilities but also his strategic thinking. Also, the fanfiction could explore how Naruto's values of friendship and perseverance would influence the use of the Gate of Babylon. Maybe he would try to use it for the greater good of his village, rather than for personal gain like some of the original users of the Gate in its own lore.
One interesting crossover could be Naruto learning about the Gate of Babylon's treasures and trying to incorporate them into his jutsu. For example, he might use some of the powerful weapons from the Gate of Babylon as a way to enhance his Rasengan, creating a more powerful and unique attack. Another aspect could be a battle between Naruto and an enemy where the Gate of Babylon's abilities are pitted against Naruto's ninja skills. It would be a clash of two very different power systems, making for an exciting read.
In a Naruto and Gate of Babylon fanfiction, a possible scenario is that Naruto accidentally discovers a portal that leads to the realm where the Gate of Babylon exists. He is then intrigued by the power it holds. He could team up with a character from the Gate of Babylon's universe, like Gilgamesh perhaps, and they would go on adventures together. This would involve Naruto learning about the rules and powers in this new world and finding ways to combine his own abilities with what he discovers there.
One interesting concept could be the combination of Naruto's world with the Gate of Babylon's abilities. For example, how Naruto characters might interact with the treasures from the Gate of Babylon. It could lead to unique battle scenarios where Naruto's jutsu and the powerful artifacts from the Gate collide.
One interesting concept could be the unique character creations. In OC (Original Character) fanfictions, the new characters often bring fresh perspectives. They might have distinct abilities related to the Gate of Babylon, like perhaps a new way of summoning or using the treasures within. Another concept could be alternative storylines. Instead of following the main plot strictly, it could explore what would happen if certain events in the Gate of Babylon's lore occurred differently. For example, different power dynamics among the characters due to the use of the Gate of Babylon.
One idea could be Naruto somehow getting access to the Gate of Babylon. He could use the weapons from it in his battles, like using the swords against powerful foes in the Naruto universe. This would give him an edge and also create an interesting dynamic as he tries to master these new weapons.
One interesting crossover could be the sharing of technology. For example, the warp drive from Star Trek might be compared or combined with the hyperspace technology in Babylon 5. Another aspect could be the meeting of different alien species from both universes. Maybe the Vulcans from Star Trek and the Minbari from Babylon 5 could engage in some sort of philosophical exchange.
Perhaps it delves into the idea of different cultures' magic co - existing. The Gate of Babylon comes from a very different cultural and mythological background compared to the Western - based magic in Harry Potter. So, the fanfiction could show how the characters in Harry Potter react to and adapt to this new, foreign type of magic. It might also involve crossovers where characters from the Potter world have to team up with characters associated with the Gate of Babylon to face a common threat, like a dark force that can only be defeated by combining both types of magic.
One possible plot could be a crossover with the 'Fate/stay night' universe. The protagonist from another series could be summoned into the world of 'Gate of Babylon' and has to navigate through its complex rules and power dynamics. They might form an unexpected alliance with Gilgamesh and together face a common enemy that threatens both their worlds.
Sasuke, on the other hand, would be more cautious. He would study the Gate of Babylon's powers first, trying to understand their limits and weaknesses. He might try to use his Sharingan to analyze the weapons and the energy behind the gate. He could then use this knowledge to either control the gate himself or find a way to stop an enemy who has control of it.
One interesting idea could be unique character interactions. For example, how characters from RWBY might interact with the concepts and entities from the Gate of Babylon. Maybe there are new team - ups or rivalries formed. Another aspect could be the exploration of different powers. Since the Gate of Babylon has a vast array of treasures and abilities, seeing how RWBY characters utilize or adapt to these could be really engaging. Also, the fanfic might introduce new story arcs based on the combination of the two universes, like a new threat that can only be defeated by combining RWBY's skills and the power of the Gate of Babylon.
Definitely consider including Batman from the DC universe. His detective skills and strategic mind would be a great addition. He would be intrigued by the mystery and power of the Gate of Babylon and would try to analyze it from every angle. His interactions with Gilgamesh would be full of tension as they both are used to being in control.
Another possibility is a fanfiction that focuses on a character from Babylon 5 who discovers Naruto - like powers. They could then use these new - found powers to fight against the various threats in their own universe. This would blend the two universes' elements in a very creative way, with the Babylon 5 character having to adapt to Naruto - style combat and abilities.
