The Feng Shui Engine (風水エンジン, Fuusui Enjin) is a miniaturized Tanden Engine which is the size of a human eyeball. The owner of this object is Juri, who uses it in both of her Ultra Combos in Super Street Fighter IV, even being the focus of one.
The limits and full potential of the engine have not been fully revealed; however, during her second Ultra Combo in Super Street Fighter IV, the engine gives her an amazing speed boost. In the 35-minute OVA (Original Video Animation) which focuses on Juri's past, she quickly overcomes Chun-Li, Guile and Cammy all at once while under its influence. The anime also shows that it cannot be used for extended periods of time (likely reflected in the time limit of her first Ultra Combo in the games); this limitation was removed later in the animation by S.I.N. scientists.
As a plot elementEditThe Feng Shui Engine was implanted in Juri's left eye socket when she was a young teenager. It acts as a replacement for her left eye, which had been badly damaged when her family was attacked and her parents assassinated by Shadaloo. Developed by S.I.N., the device enhances her fighting potential.
As a special attackEdit
Juri uses the eponymous eye during her first Ultra Combo in Super Street Fighter IV.
