If a creature can be called fugly in Skyrim....then i think an argonian vampire fits that descrpition (though it doesn't help that the lizards are ugly to begin with). Vampirisim seems to cause all races to become uglier then they were before....but the Argonians get the worst out of it.
Because of there ugliness....Bethesda should have made it, so that if a living NPC looks to long at an Argonian vamp....their eyes bleed or something....because of the horrible image.
