Canon = the offical novels and the movies themselves EU = Anything else approved for publishing under the SW brand. Okay, lets see the stuff that actually has come from EU first and got to a movie or offical novel.... 1) Battle droids - introduced in the Emperor Reborn Dark Knight comic. 2) Coruscant - was named by Timothy Zahn and also is characteristics... ie a planet turned into a city 3) Mara Jade - originally an unnamed dancer in Jabba's palace, Zahn asked Lucas who it was, Lucas did not have a name or any history... she was just a dancer. Zahn named the character Mara Jade and now we have one of the most popular SW characters of all 4) The robotic fighters in TPM are the same as the robotic TIE's in the Emperor Reborn comic 5) Dash Rendar's ship, the Outrider is seen in a new scene in ANH:SE Any more?
