Blake could be a very interesting character in a RWBY Doom crossover fanfiction. Her ability to create illusions and her cat - like reflexes could give her an edge in the Doom universe. Also, her complex backstory and her more reserved nature compared to some of the other RWBY characters would make for an interesting dynamic when interacting with the Doom Slayer and the other denizens of the Doom world. She might be able to use her stealth to sneak up on demons or create illusions to distract them while the others attack from different angles.
The Doom Slayer and Ruby. Ruby is young and full of hope, always looking for adventure. The Doom Slayer is a stoic, battle - hardened warrior. Their interaction would be really interesting. Ruby could be in awe of his strength and weapons, and the Doom Slayer might see a bit of his own unwavering will in Ruby.
The Doom Slayer and Ruby would be an interesting pairing. Ruby is young and full of energy and hope, while the Doom Slayer is a silent, stoic force of destruction against evil. Their interactions could be really cool, like Ruby trying to understand the Doom Slayer's lack of words but seeing his determination and being inspired by it. And the Doom Slayer might see Ruby's potential and unwavering spirit in the face of danger as something similar to his own.
I think Yang would be the most interesting. Her hot - headed and powerful personality would fit well in the Doom setting. She'd be charging into battles with the demons, using her Ember Celica to blast them away. And her ability to get stronger when she's angry could be a great asset in the high - intensity combat of Doom.
I think the combination of the Doom Slayer and Anya Oliwa from Wolfenstein could be really interesting. Anya is a strong and intelligent character. She could provide the Doom Slayer with valuable information about the Wolfenstein world, like the layout of Nazi bases and their technology. Meanwhile, the Doom Slayer could protect her with his incredible combat prowess. This dynamic could lead to a story where they work together to uncover a deeper conspiracy that links the demons and the Nazis.
The Doom Slayer and a Space Marine would be really interesting. They both are combat - focused and have a strong sense of duty. They could start off as rivals, each thinking their way of fighting is superior, but then come to respect each other after facing a common enemy like the forces of Chaos.
Ruby would be very interesting. Her innocent and eager - to - help nature would be a contrast to the desolate and often cruel Fallout world. She'd likely be the one to immediately try to make things better, whether it's helping a settlement or fighting against the bad guys. Her speed and combat skills with her scythe would also make her a force to be reckoned with in the wasteland.
The Doom Slayer and Charlie would be an interesting pair. Charlie is all about redemption and trying to make Hell a better place, while the Doom Slayer is focused on pure destruction of demons. Their meeting could lead to some great character development. Charlie might try to convince the Doom Slayer that not all demons are irredeemable, while the Doom Slayer could show Charlie the true horror that some demons are capable of.
However, it could also be a new character created specifically for the crossover. This character could have the best traits of both the Doom Slayer and the Master Chief. Maybe they have the Doom Slayer's combat skills and the Master Chief's understanding of technology. They could be a wildcard that changes the power dynamics in the crossover fanfiction.
I think the interaction between Ruby and Ben would be really interesting. Ruby is very energetic and has a strong sense of justice. Ben, with his experience of using the Omnitrix to save the day, could share some of his stories with her. They could also have some friendly competitions regarding their combat skills, like who can take down a group of Grimm faster, with Ruby using her Crescent Rose and Ben using one of his alien forms.
Ruby would be really interesting. Her energetic and optimistic nature would contrast greatly with the often dark and power - hungry characters in the Overlord world. She could inspire some of the downtrodden minions with her belief in the good of people. Also, her scythe skills and speed would be a unique addition to the battles in the Overlord universe.
