What is you favorite mythical creature?

Trolls

Mermaids. They're so graceful when swimming, yet are mysterious. If only they existed.

Sharon Stone

Vampire. They are the gentlemen's monster.

I don't know, I might be speaking from a bias. Obviously I am not a vampire, however the things vampires have, individually, are things I have interests in, such as blood (mainly its appearance), style (vampires tend to be stylish), sadistic (I have sadistic tendencies), and so on.
Vampires are my favourite due to their immortality, yet sadistic nature. I dislike vampires that have all these mystical powers. The only things they should have is unlimited endurance (due to being dead and all, so can't run out of breath) and immortality, that is about it.

Vampires have a certain beauty to them that I like.

OP.

God

My favourite is the everything creature

Hm, nothing really stands out to me. I went with phoenix.

I kind of like 'em all. But at the moment I like Sirens. Read a poem called "Siren Song" by Margaret Atwood, it's pretty cool and really shows you what sirens really sing about draws men to their doom.

Can't beat that noble beast.
