(Japanese: ワイ・ナ・ガーベナ Y na Gābena) is a main character in the manga series Pokémon Adventures.
Y is a young girl aiming to become a Sky Trainer. At some point in her life, she used to be a Rhyhorn racer, but later switched to her current goal.
Y is first seen congratulating her friend X for winning a tournament when they were children. When they group together with Tierno, Trevor, and Shauna, they are all pushed away by the paparazzi looking to interview X. Years later, the pressure from the press and gossip from people has caused X to become a shut-in that refuses to leave his room. Despite his friends' daily efforts to get him outside, he refuses because of his fear of having the public's eye on him. Y attempts to try and persuade X to come out with various stuff from around Kalos, but he refuses each time, angering her. Soon after, Y is approached by Alexa, a reporter, and her sister Viola, a photographer. They explain that they wish to interview Y, as she is an up-and-coming Sky Trainer. Y tells the two that she hates reporters because they're the very reason why X refuses to come out of his house.
Suddenly, the Legendary Pokémon Xerneas and Yveltal appear and begin destroying Vaniville Town in a battle against each other. Y tries to warn X about what is going on, but he ignores her once he sees Alexa and Viola recording the battle. Y takes the initiative and has her Rhyhorn get her friends to safety while she goes back to retrieve X. Upon arriving, she finds X being attacked by Team Flare for his Mega Ring. Although she tries to fight back, Y is easily knocked back and put in danger. Seeing all the commotion causes Kogaru to get angry, which allows her to become Mega Kangaskhan with the use of X's Mega Ring. Kogaru manages to easily fend off the Team Flare members and force them into retreating.
With the battle over and the Legendary Pokémon gone, the five friends group together in the rubble of their now-destroyed home town. They decide that with their homes gone, and certain things they need to accomplish, they all need to head off. Although X still refuses to to go, Y tells him that he has no choice now that he's homeless. Y forces X into a new change of clothes and the five friends set off together.
The group travels to an inn in Aquacorde Town to stay for the night. She attempts to call her mother and inform her of what happened, but gets no response. When she attempts to tell X about her attempt to call her mom, the innkeeper attacks Y and reveals herself to be allied with Team Flare. The innkeeper battles Y while Aliana and Mable attack X outside while he's alone. With Yako-chan's assistance, Y manages to get outside and finds Aliana and Mable attempting to kidnap Kogaru. Y informs X of what's going on and helps him fight off the two Team Flare members. When X's attempt to have Kogaru Mega Evolve fails due to her being away from her mother, they instead use the Froakie and Chespin that Trevor got from Professor Sycamore. With the help of the two Pokémon and the Pokédexes, Y and X defeat Aliana and Mable as well as rescue their friends from the inn. They decide to run away from Aquacorde and hide from suspicious people by camping outside.
The group continues on the Santalune City, where they gather supplies for their journey. Y contributes by buying extra clothes for her friends. She makes a set of rules for the group to make sure that they don't get attacked by Team Flare again. They soon meet up with Viola again, who reveals her status as Gym Leader and offers assistance to them. Although distrusting of reporters, Y decides to trust Viola, and the others agree with her decision. The only exception is Shauna, who runs off frustrated that Y would go against her word to not trust adults. The group stays the night at the Santalune Gym, but Y gets worried about Shauna and goes off to find her. After finding Shauna, Y notices that Shauna is acting strangely. Shauna is later caught trying to steal Garu's Kangaskhanite while she sleeps, but Y and Viola catch her in the act. Y question's Shauna's actions, but Shauna simply retaliates by trying to slash her with the Honedge she carried around. Y is protected by Viola, who takes the brunt of the attack and is knocked unconscious.
Shauna is revealed to have been possessed by Team Flare's Celosia by using her Aegislash and Honedge to control Shauna's mind. The strain of the possession proves to be too much for Shauna and she falls unconscious. Celosia attempts to escape, but X chanses her down. He is unable to catch up to her, but he is assisted by Korrina, the Shalour City Gym Leader. With her Mega Lucario, Korrina and X retrieve the Kangaskhanite and force Celosia to escape. Afterward, Viola has her injuries bandaged and Shauna wakes up. Y berates Shauna for disobeying her rules, causing Shauna to break down in tears as she apologizes. Y breaks down as well and the two share a hug as they apologize to each other.
