The names alone, of everything in Hellboy are epic.
The Ogdru-Jahad aka the Seven Gods of Chaos, Grigori Rasputin, Samael the Desolate One, The Right Hand of Doom (Hellboy's right hand), Karl Ruprecht Kronen, The Angel etc. etc. (Well...maybe it's just the bad guy, excluding Hellboys right hand). I could go on and on. The storyline is quite interesting to, being that the author of the series is inspired by Lovecraft.
