Ask HN: Who's Chewbacca to you?

This year, my team decided to name sprints after Star Wars characters. That said, I've watched approximately 0 minutes of Star Wars ever. So, I've been given the privilege of hosting a presentation of Star Wars characters based on our sprint name (my Admiral Ackbar presentation was alright, Boba Fett...not so much).

This sprint, I'll be presenting on Chewbacca, and thought it'd be a good idea to turn to you lovely people for your five minutes on who Chewbacca is. If you have, or have not, seen Star Wars, I'd love to read your thoughts (especially if you haven't seen Star Wars).
