One common theme is friendship. Since Ruby and Oscar are both important characters in RWBY, many fanfics explore how their friendship develops over time.
Well, a great moment could be when they first meet in a fanfiction. The initial exchange of words, the sizing up of each other's abilities. It sets the tone for their relationship. For example, if Ruby is in awe of Coco's cool and collected demeanor, and Coco is intrigued by Ruby's raw talent.
Sure. 'A New Bond' is a great one where Ruby and Oscar go on an adventure together and their friendship deepens. It has some really cool action scenes.
One idea could be a story where Ruby and Coco team up for a special mission. Maybe they have to infiltrate an enemy base, and Ruby's speed and Crescent Rose combined with Coco's fashion - inspired weapons and strategic mind make them an unbeatable duo.
One idea could be Ruby discovers a new form of nanotech in a hidden part of Remnant. This nanotech could enhance her Crescent Rose, giving it new abilities like shape - shifting or self - repair.
There could be many interesting fanfictions with this combination. Maybe in the fanfic, Ruby discovers a magical balloon that can transport her to different realms in the RWBY universe. It could be a tool for her to explore new areas or even a key to unlocking some hidden powers.
It's not appropriate at all. Fanfiction should be a form of creative expression that adheres to ethical and moral standards. RWBY has a large fan base that includes people of different ages and backgrounds. Creating or promoting fanfics with inappropriate content like this can be offensive and goes against the spirit of the original work which aims to tell exciting stories about heroism, friendship, and self - discovery.
A great fanfiction plot could be that Faunus Ruby is being discriminated against by some students at Beacon. Weiss, who is used to a world of privilege, decides to stand up for Ruby. This act of kindness makes Ruby trust Weiss more. As time passes, they find themselves relying on each other more and more during combat and in their studies, and a beautiful friendship (or maybe something more) starts to develop.
A common theme could be friendship development. Since they might start as acquaintances and then grow closer. Another could be adventure, if they are in a world full of exciting events.
