You haven't made Obi-Wan bald in a fic? Baldness through disease or radiation is always possible -- one would think that they could take care of radiation problems as easily as a broken limb in the GFFA -- but shaving him is much more fun. Not speaking.......I am contemplating a version of that for both Qui-Gon and Obi-Wan but that is a little further down on my list and needs more filling out. Um, I have missed a very obvious choice; violence. - shooting (blaster or projectile weapon) - blunt trauma - stabbing - explosions There is also burning by fire, plasma or chemicals, but those could be either intentional or accidental.
