Dasi Weide is how you say Darth Vader.  It’s a phonetic translation, the characters don’t mean anything, they were chosen just for their sound similarity.  It’s pronounced dah-suh-way-duh.

Annajing Tianxingzhe is a little bit different, though.  Annajing is also a phonetic translation, it doesn’t mean anything.  It’s pronounced more or less exactly how it’s spelled.  Tianxingzhe (pronounced teean-shing-juh) is different. Tian means “sky,” and it’s the same character in the word “Tiananmen.” Xing means “walk.” Zhe means “one who does something,” and modifies the word that comes before it, so when you put xing and zhe together you get “one who walks.” Thus Tianxingzhe literally means “Skywalker.”
