Don't laugh. XD The similarities between the two characters are so distinct and obvious that comparison is inevitable for anyone who's read/watched both series. I seriously thought when I first noticed Black Butler(more popularly referred to as Kuroshitsuji) that it was literally an anime adaption of Artemis Fowl. Other people have read Artemis Fowl and thought "CIEL HAS A CLONE??!?" So I thought I'd outline some of the differences and analyze who would win. XD Similarities: Appearance: This is the first similarity, and one of the most major, because if they didn't look so darn alike I don't think the comparison would have been as striking. The above picture of Artemis is a fanart, because there aren't really any good pictures of Artemis, and the manga style makes it more obvious. They are both from the British Isles and have black hair and blue eyes. Both of them lose/change/switch an eye resulting in two different colors.
