The Manhunter:
Maybe this one? Or are the lizard men more lizard, less men?
Their TRUE form is more lizard, less man. But this can be a form he shows the public when adventuring.
Real lizardmen see The Manhunter (and his ring) as a very disturbing relic of a time ages past, like if Genghis Khan rode up to your picnic holding a huge bloody axe... but way worse than that. (More like if Conan rode up to your picnic holding a glowing skull that he was looking to get rid of somewhere?) So he feels closer, emotionally, to humans (even though he would freak them out almost as much if they saw his true form, and even though he doesn't feel that close to anyone in the present really).
