Jar Jar, for the most obvious reasons.
C-3PO. Outside of the OT, I wanna melt him, and pour him down Cassius' throat.
Marek. Not as a character, but his powerful Force command is ridiculous.
Sion. For being a whiny b*tch.
Revan. For being a Gary Stu. Aside from that, the whole premise behind his character and KotOR's story is awesome.
Chewbacca. Outside of the movies, he's incredibly annoying to read about.
Lumiya. Never read anything with her in it, but I just don't like her.
Caedus. No need for another Sith.
Krayt. No need for another Sith.
Bane. I found him rather boring to read about as soon as he took on the Darth mantle. His build-up was okay.
Plagueis. He's served no real purpose as of yet that Sidious couldn't have done.
Orn Free Taa. Fat f*ck.
The characters from the Galaxy of Fear series. Kids' books, sucked.
