Excited to share them and have your feedback, Del!
I agree that I would have liked to see Krell in a modified role. I was never a big fan of the Umbara arc, mainly because I felt like Krell was too much of a cackling villain who was offensive for the sake of it. I’ve tried to reduce that as much as possible, but I found that there was a necessary balance with having him be a hardliner versus still being a legitimate foil for the main characters, so settled on making him already in league with the Separatists and reducing a lot of the more cartoonish mannerisms.
Ultimately though, the purpose of his character is to represent ‘evil order’, which is the final step on Rex’s journey learning about his relationship with orders in preparation for Order 66. And there isn’t much more material that could be used to recontextualise his character.
