Do you remember the lightsabre fight between Obi Wan and Darth Vader? At the end of that fight Obi Wan says "if you strike me down Darth, I will become more powerful than you can ever imagine" And ol' Darth, never one to look a gift horse in the eye lops his noggin off. 1. Why did Obi Wan say that and, given the following movies, apart from a few spectoral scenes, did he ever get more powerful? He certainly didn't have a huge impact in SW except for his advice to Luke ("use the force Luke, Use the force!") when he was about to shoot his photo torpedo'sâ¦ 2. Why did his body vanish leaving just his old monk like clothesâ¦ Anyone got any answers?
