In this Chinese name, the family name is Ling (凌).
Ling Xiaoyu (凌 曉雨 Líng Xiǎoyǔ; Japanese: リン・シャオユウ Rin Shaoyū) is a fictional character who was introduced to the Tekken franchise in Tekken 3 as a 16 year old girl and has returned in every subsequent release. Xiaoyu's fighting style was brought on with some influence from her master, Wang Jinrei. Her main goal throughout most of the series is to, through fighting in the tournaments, win so she can earn enough money to build her own amusement or theme park. However, in subsequent games of the series, Xiaoyu more focused on Mishima family's issues, in particular on Jin Kazama. Her role in Tekken 6 is equal to the storyline Jun in Tekken 2.
Xiaoyu is a 16 year-old who loves amusement parks. Entering the Tournament is her first step in having the perfect amusement park built in China.
CUTE, SPIRITED, HAS PANDA... WILL TRAVEL. This young girl loves amusement and theme parks. Her dream is to build the perfect amusement park in China when she grows up.
She is both young and small in stature but Xiaoyu is a skilled martial arts expert. Many believe if she was more serious she could achieve real greatness. Having learned that the Mishima Estate is rich and powerful she seeks out Heihachi (president and CEO) to make her dream a reality.
While vacationing in Hong Kong with her family, Xiaoyu stowed away on a yacht bearing the name, Mishima Financial Empire. Heihachi was not on board but Mishima's men discovered her soon after the ship left port and Heihachi was informed immediately.
Upon his arrival, Heihachi found his men beaten and strewn around the ship as if it was hit by a hurricane. She threatened that she would go berserk again if he did not accept her challenge. Roaring with laughter, he promises to build the amusement park of her dreams if she wins the tournament.
Ending Description, "Dreamland?": Heihachi Mishima keeps his promise, and builds Xiaoyu a theme park. Xiaoyu imagines a place full of happiness and color named "Xiaoyu Land". However, when her daydream ends, Heihachi unveils the real theme park, which is a gloomy place he calls "Heihachi Land". Heihachi roars with laughter. Xiaoyu gets angry, and beats up Heihachi, yelling "Jerk". Oddly, this ending is combined with anime-like animation & CGI.
Xiaoyu was a junior at Mishima High School. She still lived, studied and trained as a ward of the Mishima Zaibatsu. But lacking any particular goals, Xiaoyu grew tired of her everyday routines.
However, one day, she received an anonymous e-mail that warned her of Heihachi’s evil intentions and the danger to her life. Xiaoyu replied to the e-mail, but she did not receive any further messages from the anonymous individual.
Xiaoyu's intuition told her that Jin Kazama, who had been missing since the last Tournament, could have sent the message. She believed the message and started to suspect Heihachi and the Mishima Zaibatsu.
Upon hearing the announcement of the next Tournament, Xiaoyu made the decision to enter — hoping to be reunited with Jin and to unveil the truth behind Heihachi and the Mishima Zaibatsu.
Ending Description: Victory for Xiaoyu in the Tournament is not only a victory that few believed possible but also one that reveals the Mishima Zaibatsu's evil deeds for all to see. Soon after, Miharu Hirano is shown visiting an executive's office, and the chair behind the desk swivels around to reveal Xiaoyu, who has taken over the Mishima Zaibatsu. Miharu wonders what Xiaoyu is doing in the office, and when she replies that she's working, Miharu replies that she looks like she sits there and does nothing. Xiaoyu casually asks her friend how she did in her college entrance exams, and Miharu confesses that she has flunked all of them.
Wanting to help her friend, Xiaoyu offers her a job with the Mishima Zaibatsu, stating that from now on, she is going to make her own dreams come true. She tells Miharu that she saw Jin after the tournament and that he told her if she has a dream that she wants to come true, she should make it happen herself. Miharu lightly teases her, but recognizes a change in Xiaoyu, who used to depend on everybody else. Miharu agrees to work together and asks her friend what her dream is. Xiaoyu points out the window and responds, "Help me build that." The camera reveals a massive theme park being built with Mishima Zaibatsu funding and resources.
Tekken 5 Manual Version
Xiaoyu cried when she heard Heihachi had been killed. In her sorrow, she wished she could go back in time. One day, Xiaoyu met a self-proclaimed genius who boasted he could invent a time machine if only he had the money. To fund the invention, Xiaoyu decided to enter the tournament.
Official VersionXiaoyu is a high school student who is on a personal mission to save the Mishima family. In the previous tournament, Xiaoyu was saved from the evil plans of Heihachi by Yoshimitsu, who taught her the history of the Mishima family. Hearing this, Xiaoyu began to believe that the root of all misfortune surrounding the Mishima's started with Heihachi's cruel upbringing of Kazuya.
When Xiaoyu heard of the death of Heihachi, a tear came to her eye. "If only I could turn back time..." Xiaoyu said with a hint of sadness and regret.
Later, Xiaoyu happens to meet a brilliant scientist who claims that he can make a time machine as long as he gets the funding for development.
Under the condition that she will be first to use the machine, Xiaoyu pulls out the wadded scrap of paper in her pocket... an invitation to the King of Iron Fist Tournament 5.
After defeating several people, Xiaoyu finds out that her next opponent is Jin. Jin Tells her that the tournament is dangerous and tells her to leave. Xiaoyu argues that if certain things didn't happen in past Heihachi wouldn't have died like this and she's going to turn time back, to which Jin says that things can't be reversed and Heihachi is dead.
After defeating Jin, Xiaoyu apologizes and says that after she wins the tournament they can go back to good times.
After Jinpachi Mishima is defeated by Xiaoyu, he thanks Xiaoyu and disappears. Xiaoyu gets confused and after a while she frustratedly says "What do you mean "thank you"? Who am I supposed to get the prize money from?"
Ending Description: After winning the tournament, Ling Xiaoyu is the first to use her time machine. She travels back to the time when Heihachi Mishima was about to throw Kazuya off of a cliff, intending to avert this event that will rip the family apart. Unfortunately, Xiaoyu had lost control of the time machine and it barreled into Heihachi and Kazuya, sending Kazuya falling off of the cliff, while Heihachi is nearly sent over himself. Xiaoyu is wretched because of her failure, and the old scientist comes to her, laughing, and tells her that nobody can really change the past, remarking "The best you can hope for are minor improvements." This ending is also animated.
Ling Xiaoyu breathed a sigh of relief when she heard Heihachi had not truly died. However, as head of the Mishima Zaibatsu, Jin Kazama aims to take Heihachi’s life. Xiaoyu was going to try and stop Jin herself, but the Zaibatsu pushed towards militarization, making it difficult to approach Jin.
The Mishima Zaibatsu’s declaration of war drew hostility from around the globe. When the King of Iron Fist Tournament 6 is announced, Ling Xiaoyu enters in the hope that she can save Jin’s soul from evil.
Ending Description: Xiaoyu meets Jin on a rooftop, where he is on the ledge about to jump. "No Jin! Don't do this." she says, but Jin sadly replies, "The evil I've perpetrated...can never be undone." He makes to sacrifice himself, but Xiaoyu jumps onto the ledge and hugs Jin, saying, "I...I'll stand by you~ Please... You can't do this!" After having a conversation, Jin says, "Thank you, Xiao". Suddenly, it's revealed that the sequence was just a dream. She wonders if she hugged Jin but no; it was Panda. After Panda pushes off Xiaoyu, she wakes up, but is still half-asleep, asking, "Where am I?", not realizing right away that it was just a dream.

Xiaoyu is featured as a playable character in Tekken Revolution.
Xiaoyu is a playable character in Tekken Card Tournament. Her cards focus on frequent draw-power at the price of having overall weak stats, making her akin to a lightning bruiser or fragile speedster . She also lacks many parries, and although she can boost her damage output with certain cards, these cards are somewhat more tricky to activate. She is not recommended for beginners, as balancing her decks can be tricky, but when mastered, she can be a very annoying adversary. Also noteworthy is that the game developers have stated that Lili players are a tough match-up for her, as Lili basically feeds off of Xiaoyu's plentiful cards to activate her own card abilities.
