C-3PO is the lovable "complainer" in the Star Wars galaxy. He seems to have a very "glass half-empty" view of the world, but always seems to come through in the end when it is needed.
"R2 says the chances of survival are 725 to 1!"
"Don't you call me a mindless philosopher you overweight glob of grease!"
"Sir, it's very possible this asteroid is not stable."
