Pretty sure GJ was supposed to be rather plain looking (despite the TV portrays), LHC and WXB are both rather average in terms of looks as well, though both are pretty charismatic.
XZ is always described as plain if not down right ugly, and I think SPT is also pretty average in the look department.
Granted, YG, DY, and ZWJ are the pretty boy protagonists, while XF has the whole macho thing going for him.
