Well, such a fanfiction would be quite a game - changer. In the normal Star Wars fanfiction world, stories often build on the positive relationships between characters. But if Ezra kills Kanan, it could lead to a whole new genre of 'dark' fanfiction within the Star Wars community. It might inspire other writers to explore more extreme and morally ambiguous storylines, and it would definitely make readers re - evaluate their understanding of the Ezra and Kanan relationship.
There could be characters like Hera Syndulla. She is often associated with Kanan and might play an important role in the graphic novel. Maybe Ezra Bridger could also be in it as he has a connection to Kanan in the Star Wars lore.
Whether the Kanan comics are canon is a matter of debate. Some aspects might align perfectly with established lore, but there could be elements that don't quite fit. It's not a straightforward yes or no answer.
Percy is likely a character within the context of this fanfic. Without more information, it's hard to say exactly who he is, but he's probably someone with the ability to take the power of things he kills.
Well, it's a bit complicated. The determination of whether the Kanan comics are canon often depends on the decisions of the creators and the broader narrative context. Sometimes new developments or retcons can influence this status.
