Okay. I had this image of the skinny teenager with jet-black hair over one eye, listening to Linkin Park and whining on his LiveJournal page. Yes, Conan was kind of a mopey and surly fellow. Howard sometimes described him as having gigantic mirth, roaring with laughter and so forth, but we nearly always see him as grim and taciturn, not a fun guy to hang around with.
Elric, though, had angst and weltschmerz pouring off him.
