Teg was a pretty cheese character tbh. Moneo was fun in a somewhat dry way, best part was when he casually owned Duncan both physically and verbally and it wasn't even his first Duncan. Actually it's pretty funny that while i think Dune is the best sci-fi cycle ever, i don't even like anyone there particularly.
Probably Odin, he's so fucked in the perfectly twisted entertaining mythological way. He's also super popular in popculture making me enjoy so many different views on him.
