The meaning of Darth Vader's name as a reference to him being Luke Skywalker's father is not true, but the name of one character from The Mandalorian has a lot deeper meaning. There are many Star Wars characters whose names carry a weight of significance. Sometimes, of course, these become the subject of legend – as in the example of Darth Vader. A popular myth claims that Darth Vader means "Dark Father" in Dutch or German. This was fanned by George Lucas himself, but it can't possibly be correct; after all, there's abundant evidence Lucas didn't come up with the idea of Darth Vader being Luke Skywalker's father until the second draft of The Empire Strikes Back.
