Well, Corvo's story of his journey to clear his name is quite remarkable. He was wrongly accused and had to use his stealth and combat skills to fight back. His loyalty to the empire, despite the betrayal he faced, makes for a great tale. He overcame numerous obstacles, from the corrupt guards to the political intrigue in Dunwall.
For Corvo, it's definitely his encounters with the Outsider. The Outsider gives him his powers, and these moments are quite significant as they mark the start of his transformation into a more powerful figure. It changes the course of his fight against the tyranny in Dunwall.
Well, obviously Corvo would be one of the main characters. He would bring his own set of skills, like his combat abilities and stealth techniques. Then, from RWBY, Ruby Rose could be a main character. Her leadership skills and scythe - wielding combat style would contrast and interact with Corvo in interesting ways.
The world - building aspect is also worth noting. Combining the two universes of Corvo and RWBY can result in some really cool settings. The fanfic might create new locations that are a blend of the dark, steampunk - like world of Corvo and the colorful, yet dangerous world of RWBY. This can provide a rich backdrop for the story to unfold.
There's also 'The Outsider's Gift to Corvo'. In this fanfic, the Outsider bestows a special power on Corvo that he has to learn to control. It has great character development and explores how Corvo copes with this new ability in a world full of chaos.
One great example could be a fanfic that focuses on Corvo's early days before the events of Dishonored. It might explore his training and how he became the skilled assassin we know. Another could be a story where Corvo has to face an unexpected new threat in Dunwall. And there are also fanfics that delve into his relationships, like his bond with Emily in a more in - depth way.
Ezio Auditore from 'Assassin's Creed' would be a great choice. Both are masters of stealth and combat in their respective worlds. They could compare their different techniques, for example, Ezio's use of the hidden blade and free - running skills against Corvo's supernatural abilities like possession and his sword - fighting skills. Their meeting could be set in a city full of secrets and political unrest, where they have to work together to uncover a conspiracy.
First, study the Dishonored lore thoroughly. Know all about Corvo's character, his abilities, and the world he inhabits. Then, come up with an interesting plot. It could be a new mission for Corvo, or a personal journey he undertakes. Make sure to keep his personality consistent. He's a complex character, so don't make him act out of character. Also, describe the setting well. Dunwall has a unique atmosphere that you need to capture in your writing.
One idea could be a crossover with the 'Assassin's Creed' universe. Corvo could team up with an Assassin to take on a powerful and corrupt organization that has a hold over both their worlds. They could exchange skills, like Corvo teaching the Assassin some of his magic - such as Blink - and the Assassin showing Corvo new ways of stealth and combat with their hidden blade and acrobatic skills.
