To celebrate Star Wars Weekends at Disney's Hollywood Studios this year, Etckt made a periodic table featuring the characters from Star Wars! Of course, Luke Skywalker and Darth Vader are the most elemental characters, with Grand Moff Tarkin up there, too, for some reason. You can recognize some characters by their initials and standing, or see the full-size version at the link to read them.
The allegiances of the characters are categorized, and their order of appearance and movies are numbered in each cell, although in the Arabesh language. Read more about how the chart is put together at Etckt. Link -Thanks, Matthew!
