Most offensive Star Wars character

[Progressive Pessimist]

Jar Jar, Nute Gunray, and Watto are all tied for most offensive.

I would include Captain Phasma too actually. Not for being any sort of affront to a demographic or culture, but because she was so poorly utilized in both of the films she appeared in. She came off as nothing more than a toy advertisement. So in some sense, that's pretty offensive. Sure, there have been other characters in the franchise that were meant solely to be products, but they at least had more impact on the plot than Phasma ever did.

Im going to answer from a actual story telling perspective: Rose. Every other character in the series I can think of one or two things that they actually contribute to the narrative. Rose has nothing

Wrong. She contributed to the biggest laugh I got out of 'The Last Jedi.'

When she abruptly confessed her love for Finn right before collapsing, Finn immediately stopped caring because he realized Rey was present on the planet. Finn basically said "yeah, sure, whatever, Rose. REY'S HERE!? WHERE IS SHE!?" Hilarious.

Kathleen Kennedy.

I'll give you that one. She really dropped the Jedi training ball with the direction the franchise is going.
