Unofficial name for a terribly designed Chinese Saber (Fate/stay night) figure. When pictures of the figure were originally posted on 4chan, the person posting the images called her "Sader" and the name stuck. It had reached a somewhat cult status in Japan and this particular figure is highly sought after by some, including Miyagawa Takeshi, the sculptor of the "Original" Saber figure that "inspired" the Sader figure.
Chinese and Japanese name: 邪神セイバー (Jashin Saber, Evil goddess Saber)
