What fake name did Obi-Wan Kenobi use when he first met Luke Skywalker?
As you may remember, destiny (or the plot) brought the droid R2-D2 to Luke Skywalker, thus making him a part of the intergalactic war. R2-D2 had crucial plans of the Death Star in its memory. Unfortunately, the droid went missing and Skywalker went looking for him. He got attacked by the Sand people during the process and was saved by Obi-Wan Kenobi, who initially hid his identity from Luke.
It is understandable why Kenobi didn’t want to reveal himself. After all, the Galactic Empire was hell-bent on hunting down all the remaining Jedi Knights and Kenobi didn’t want to make it easy for them.
