One interesting concept could be the combination of Hellsing's dark and gritty vampire lore with RWBY's unique world of Huntsmen and Grimm. For example, seeing how the powerful vampires from Hellsing would interact with the various characters in RWBY, like Ruby and her team. Maybe the vampires would be seen as a new type of Grimm by the RWBY characters at first, leading to some initial confusion and intense battles.
It's hard to say for sure, but Ruby Rose has the potential to be very powerful in a crossover. Her silver - eyed warrior powers are still somewhat of a mystery in RWBY, and if combined with the knowledge and abilities from Hellsing, she could become a force to be reckoned with. Also, her leadership skills and the fact that she is constantly growing in power throughout RWBY could give her an edge in a crossover scenario where she has to adapt to new threats like the vampires from Hellsing.
One common theme is the clash of different power systems. In Hellsing, there are vampires and powerful anti - vampire weapons, while in RWBY, there are the Huntsmen and their unique abilities. Fanfictions often explore how these power systems interact when the two universes collide.
One common theme is the clash of different power systems. RWBY has its Dust - based powers and Huntsmen, while Hellsing has vampires and their unique abilities. Fanfictions often explore how these powers interact.
It could make them more aware of different power systems. The Hellsing Abridged fanfiction has a complex power structure with vampires and vampire hunters. RWBY might start to think about how their own powers compare and contrast. For example, Ruby's scythe - wielding skills and semblance might seem different from the more supernatural powers in the fanfiction.
One idea could be that the characters from Highschool DxD end up in the Hellsing universe. Maybe Issei and his friends are mistaken for new types of vampires due to their devil powers. They then have to team up with the Hellsing organization to clear their names and also fight against a common enemy that is threatening both the devil and human worlds in this combined universe.
The exploration of morality is also a big theme. When Hellsing crosses with a more 'pure - hearted' universe like 'My Little Pony' (in some very creative crossovers), it forces the characters to re - evaluate their views on good and evil. Alucard's brutal nature might seem out of place in the colorful world of ponies, and this contrast creates interesting moral discussions.
Another theme is the character crossovers. Writers like to put characters from RWBY and Hellsing in the same situation and see how they react. For example, Ruby meeting Alucard would be an interesting scenario. It's about exploring different personalities and how they would mesh or clash.
In these crossovers, a common theme is the struggle between good and evil. Walter is often in a position where he has to decide which side he truly stands on in the Hellsing world. Another theme is the concept of time. Sometimes the fanfictions play with the idea of time, like Walter being sent back in time within the Hellsing universe or having to deal with time - related anomalies. And friendship is also a theme. His relationships with the characters in Hellsing, whether they develop into true friendships or remain strained, are often explored in these fanfictions.
There are quite a few. One interesting aspect is seeing how the moral and ethical concepts from both 'Bleach' and 'Hellsing' clash or blend. The storylines often involve the characters from both series having to team up against a common enemy that is even more powerful than what they usually face in their own respective worlds.
