A Code Geass AU where V.V. overthrew Charles became Emperor of Britannia. Can be read here.
Zero of The Black Crusade examples of:
- Adaptational Heroism: Charles here isn’t a Social Darwinist tyrant who plans an Assimilation Plot, but a more benevolent ruler and father.
- Adaptational Villainy: V.V. was never a good person, but here he kills and overthrows his brother.
- Big Bad: V.V. serves as this where he overthrew Charles and took over as Emperor.
