There are two images of him as an Adult and an Elder hidden in his character files and these pictures are quite different than the teenage Luc, with different facial structures and a different eye color. It is understandable why the Adult image is there, as Luc is actually an adult, but it is unknown why the Elder image is there. These pictures also show his true facial structure - the 6th face template - the one he gets if he ages up or looks in a mirror.
