Just wondering if anyone knows the rationale for dubbing Anakin "Darth Vader". Was it just a name off the top of Sidious' head, or is there a meaning behind it? "Darth Maul" is obvious. He's a blunt instrument of war. "Darth Tyranus" implies that he's a "tyrant", a feared leader. "Darth Sidious" could be short for insidious. What does "Darth Vader" mean?
