JJ is a solid looking man, from his 5'10" frame (which, is not muscular, just hard and lean in a medium, almost sculpted build), to his visage.  One thing anyone notices about him straight away (or should do), is that he seems to have no hair: not on his head, no eyebrows, no facial hair at all except for eyelashes.

He wears a neutral expression on his face, neither harsh nor open, but there is an edge just underneath the surface.  That aside, he is rarely quick to anger and has a good temperament, which makes him relatively easy to get along with ... once you get to know him.  It is this side of himself he openly shows to others.
