Weiss might also be a good choice. She is highly intelligent and comes from a family with military knowledge. She could use her strategic thinking to plan battles and manage the resources of the battleship effectively.
Ruby could be a great captain. She has natural leadership skills and is always quick to make decisions in the heat of battle. Her speed and agility could also be an asset in controlling the battleship during combat situations.
Weiss, with her more refined upbringing, could initially be a bit shocked by the differences in the Yamato's world but would soon start to find ways to use her skills. She might help with strategic planning, using her knowledge from Beacon Academy.
Ruby Rose is often involved. Her speed and scythe - wielding skills can be really useful on a Dreadnought battleship, whether it's for fighting Grimm or helping with ship - related tasks. Weiss Schnee is also common. Her ice powers can be used for defense or to cool down overheating ship systems.
In some RWBY Dreadnought battleship fanfiction, there could be a scenario where the ship gets lost in a strange dimension. The RWBY characters then have to figure out how to navigate back to their own world while also dealing with any threats that exist in that dimension. Maybe there are new types of Grimm or other hostile forces that they encounter on the Dreadnought in this strange place.
One interesting storyline could be a crossover where the RWBY characters find themselves on the Battleship Yamato. Maybe they have to work together to face a common enemy that threatens both their worlds. For example, a Grimm invasion on the Yamato's world.
Another plot could involve a race between different teams in RWBY to claim a powerful battleship. This battleship could hold the key to some great power or knowledge. Along the way, they face various challenges and obstacles, both from each other and from external forces.
Ruby would be a great choice. She has natural leadership skills and is very determined. Her quick thinking and ability to adapt would be useful in leading an esports team in high - pressure situations.
One idea could be that Captain America is somehow transported to the RWBY universe. He could team up with Team RWBY to fight against the Grimm. His shield would be a unique weapon in that world, and his leadership and combat skills would be highly valuable.
Red Skull could be the villain. Since he has a long history with Captain America, in a fanfiction where Captain Carter is involved, he could be resurrected or have found a way to cross over from another dimension. He would see Captain Carter as an interesting new threat and Captain America as an old foe to be finally defeated.
He could be a mentor figure. Captain America has a wealth of combat experience and strong moral values. He could train the RWBY characters, especially in hand - to - hand combat and strategy. His presence would add a new dynamic to the Beacon Academy training sessions.
Perhaps there is a common enemy that forces Captain America and the RWBY characters to work together. This enemy could be a powerful being that has the ability to manipulate both the technology in Captain America's world and the Dust in RWBY's world. The combined forces of the two universes would have to find a way to defeat this enemy and in the process, learn from each other's strengths and weaknesses.
