So here's The Admiral - objectively the best character out of all seven (at the time of writing) Star Wars films (and probably all the books and comics and games and that too... but I'm just assuming there).
I read this list of trivia about Ackbar when I was looking for source imagery and read this great thing about how Richard Marquand deliberately picked the weirdest concept design they had lying around when he was deciding how he should look. And he stuck by it when people said it was going to look dumb as Hell. Later on he said, "I think it's good to tell kids that good people aren't necessarily good-looking people and that bad people aren't necessarily ugly people." Which makes up for a thousand Ewoks.
