One likes red, two like red and black, and one likes black.
One has black hair, two have blonde hair, and one can't make up his mind.
One has black eyes, two have golden eyes, and one has green eyes.
One's not human, one's half-human, one's not quite human, and one is human.
Two are tall, and two are short.
Two live in a fictional past, and two live in a fictional future.
All of them are on a quest.
All of them are angst-ridden.
And all of them are stubbon as hell to boot.
Can you guess who they are?
