Well, the main characters are bound to be at least some of the RWBY crew. Ruby, being the protagonist of RWBY, would probably be right in the middle of the action in the 'rwby gate of babylon fanfic'. She's curious and always ready for an adventure, so she'd be likely to explore the mysteries of the Gate of Babylon. Weiss, Blake, and Yang would also be important as they are Ruby's teammates and they all have their own unique skills and personalities. Additionally, there could be antagonists or side characters from either RWBY or the Gate of Babylon's lore that could become major players in the fanfic, but without reading it, it's hard to say for sure who else would be a main character.
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.
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.
Hermione might also be a main character. Given her thirst for knowledge and her ability to research, she could be the one to dig deeper into the mysteries of the Gate of Babylon and how it relates to their magic. Maybe she finds ancient texts in the Hogwarts library that hint at the existence of the Gate of Babylon and its significance in their world.
The main characters typically include the OC, who is designed to fit into the world of the Gate of Babylon. They might be a hero trying to master the powers of the Gate or a villain seeking to misuse it. Then, there are the characters from the original story that are relevant to the Gate. For example, the servants who might interact with the OC in various ways, either as allies or opponents. And sometimes, there are other original characters created by the writer that are related to the OC, such as a mentor or a sidekick.
In 'naruto gate of babylon fanfiction', Hinata could be quite popular. Her gentle nature combined with the potential of having access to the Gate of Babylon's powers can create interesting storylines. Also, Kakashi might be a favorite. His experience and cool-headedness can make for great interactions when dealing with the new and strange elements from 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.
Obviously, Artyom would be one of the main characters. And then there would likely be the main RWBY characters like Ruby, Weiss, Blake, and Yang. They might interact with Artyom in different ways. For instance, Ruby could be curious about Artyom's weapons or his background.
It's also possible that the fanfic could focus on side characters from RWBY but in a new light related to the'shine' concept. For example, Penny could be a central character in the 'rwby shine fanfic' if the story is about how her robotic nature can shine in a different way, like her circuits starting to glow with a new kind of energy that changes her abilities and her role in the RWBY universe.
Well, of course, Emiya is one of the main characters. He brings his own set of skills, like his swordsmanship and his ability to project weapons. Then there are the RWBY characters such as Ruby Rose. Ruby is a key figure as she is the leader of Team RWBY. Her innocent yet determined nature often clashes or combines interestingly with Emiya's more stoic and experienced personality.
Well, it likely still features the main characters from RWBY like Ruby, Weiss, Blake, and Yang. But in the context of redemption, perhaps there are new characters or side characters who play a crucial role in their journey towards redemption. Maybe an old enemy who now has a change of heart and becomes an ally.
