Luthor knows the importance of a good disguise when there's no one around to care or ask questions. I bet he does it at home to his girlfriend.|
"Ha ha ha! You do not know what I, the mysterious stranger, is doing in your house! You are asking yourself, who is this man?! What does he want with me? I do not recognize him!"

It's a good mask too. He transformed himself from a bald man to a bald man with a face that's kind of hanging off. Sinestro went even one deceptive step further. With one simple crappy mask, he transformed himself from a purplish freak to kind of a pinkish freak without pupils in his eyes. I guess he did manage to jam some of that insane chin in, so I maybe not everybody would have recognized him. These guys would probably have more convincing masks if they just slapped some sandwich meat to their faces.
Witness Their Dramatic Transformations!
