An AU version of what he could've been had things turned out differently. Art for Antediluvian Poet from ff.net - Gift for Tom Riddle's birthday - 31st December.
This is Voldemort and his two main Death Eaters, Bellatrix Lestrange (left) and Lucious Mlafoy (right, also Draco's father).
I might be insane for saying this, but I actually find Voldemort in his serpentine form mildly attractive. Of course, it doesn't compare to my mental image of him when he was younger and infinitely more handsome.
