I chose Elfangor.
In my mind, I really can't think of a more tragic hero than Elfangor, in all of literature. First he gave up his family and ran away to Earth out of guilt and shame, and learned to live a happy life there, falling in love with Loren.
Then he was taken away and THEN he found out he had a child. In the book you really could feel just how guilty he felt in that moment, and he was even able to tell that Tobias had a lonely life ahead of him.
Then he had to live with that. For 13 years. And when he finally got the chance to fight the war, he got completely owned, and on his deathbed saw his son. (Which was a good thing, but how terrible would it be to finally see your son and realize that you have two minutes with him, and that's it.)
Then he got nommed.
I think that significantly qualifies him to be the Universe's official chew toy. (Or the ellimist's at least.) And he unfortunately passed his bad luck down to his kid.
