sien-Ko is another character from Darkstalkers, which automatically qualifies her for the "Best Halloween Costume of the Year Award." She is Chinese and has steel-like arms that can mutate and change forms. She may appear to have a strong pattern because it moves diagonally accross, but this is far from the truth. Hsien-Ko has a terrible pattern. When her diagonal pattern is dropped on an opponent, many times, huge gems will be formed because your opponent's "surface" is not flat, but has some gems that are higher or lower than others. Thus, her pattern will usually be shifted in a way that large gems will be formed. Use Hsien-Ko with caution. She is an average choice for both beginners and advanced players.
