my faves are Vampires-(not that twilight sparkly nonsense)-, Ghosts-(Danny Phantom)-, Mermaids, Witch/Sorceress's, Elf's/Hylian's, Dragon's, Phoenix, Pegasus, unicorns.(NOT MLP.) I think those are the ones I've liked through my life.
I think a lot of mythological creatures are awesome. I can think of many. I think that the Babylonian sirrush (the dragon-like creature depicted on the Ishtar Gate) looks awesome. Griffins and harpies also look amazing.
GASP! What about Pookas! What about minotaurs, gryhpons, sprites, pixies, drawves, leprechons, selkies, chimeras, sphinxes, centaurs, satyrs...*goes on for ten hours naming almost every single mythilogical creature ever imagined by humanity* What about them?
