X & Y arc
Viola first appeared with her camera and Alexa near X's house. They wanted to interview Y because of her skills as a Sky Trainer. Y however disliked them because journalists are the reason why X didn't want to leave his house. Both Alexa and Viola saw the rampage between Xerneas and Yveltal. Viola asked Alexa what is was about and Alexa told Viola about the legend she has heard.
As the group visited Santalune City and started talking about X's Mega Ring, Viola approached them and introduced herself as the Gym Leader. Viola remembered Y claimed all reporters are selfish, but Viola only wanted to share information about Vaniville Town's incident. The group agreed to follow Viola, except Shauna, who felt they know nothing about Viola. Shauna felt betrayed and left on her own.
Soon after, X agreed to a battle against Viola and used his Kanga to defeat her Vivillion. X smiled his old tactics to counter an opponent's attacks worked, making Viola a bit sad, for she is known to be "the one who doesn't allow a single smile escape away". Viola let everyone sleep at the Gym for the night. Shauna attempted to take X's Mega Stone, but Y and Viola confronted her, knowing well Shauna was stealing. Shauna pulled out a sword, a Honedge, and started attacking Y, so Viola jumped in and took the hit.
After Korrina arrived, Viola, despite being hurt, explained Korrina was a Gym Leader of Shalour City, for she asked Korrina to come examine X's Key Stone, an item Korrina had as well. Before Celosia attempted to escape, Viola had Surskit use Sticky Web to trap Celosia. Afterwards Viola had her injury in a bandage, Shauna woke up and apologized to Viola for injuring her, Viola tells Shauna that's it's nothing serious and she'll get better soon, and tell's Shauna that it's not her fault, then Viola watched as Shauna and Y reconcile, she placed her hand on Shauna's shoulder as Shauna and Y were crying.
Later on, Alexa contacted Viola, still having her head in a bandage, much to Alexa's shock. Viola ask's Alexa if she remembers Y and her friends from Vaniville town. When Alexa says "Yes", she explains everything that happened at her gym. Viola tell's Alexa she's okay, but admits she's worried about the quintet. Viola asked Alexa to find Y and her friends and protect them, for a mysterious group has been attacking them. After her Helioptile was saved, Alexa decided to go to Santalune City to meet up with her sister, Viola, to uncover the truth behind Team Flare. Later Viola told the other Kalos Gym Leaders that Team Flare attacked her and her sister, which made Valerie upset for not telling them sooner, but Trevor states they didn't know who they can trust.
Much Later￼, Viola (now fully recovered) learns that the ultimate weapon was built over 3,000 years, and it could be used to destroy the world. When Viola wonders if there is a way to stop the ultimate weapon, Alexa tells her it was 3,000 years ago from the present day. Viola knows something is bothering Alexa and asks "what is bothering her". Alexa states she doesn't know, but tells Viola she has a bad feeling about something. Alexa and Viola watched Lysander's holo coster broadcast revealing himself to be Team Flare's Leader, and they'll use the ultimate weapon to destroy Kalos and every other humans except for Team Flare. They realize with terror that they are going to use the ancient Pokémon absorber to take the lives of Pokémon to fire the ultimate weapon. Then they are approached by Clemont, Bonnie, Yvette, the Sky Trainers, and the other Kalos Gym Leaders (except for Korrina). They all went to Route 10 to stop Team Flare from firing the ultimate weapon. The Sky Trainers Vivillons (and possibly Viola's Vivillon) all use Powder to cover the whole area. When Malva's Delphox noticed their presence, it attempted to attack them with a Fire-Type move, but when the flames hit the Powder, it created a giants explosion that got rid of the security set there to keep anyone from interfering with there plans. Alexa, Viola, Clemont, Bonnie, Yvette, and the Sky Trainers reveal themselves, ready to stop Team Flares plan.
While Viola's Vivillon carries her in the air, Yvette tells the Sky Trainers to let Viola￼ lead them, wanting redeem themselves for letting Team Flare hypnotize them earlier. Viola want to free the Pokémon from the stone pillars, to stop the draining process. Alexa wants them to be careful, and advising them to be smart and not get caught in the stone pillars themselves. Alexa, Clemont, and Bonnie try to destroy the stone pillars, but they are attacked by Malva's Delphox Mythical Fire. Viola tell's the Sky Trainers to have their Vivillons use Hold Hands while forming a circle, to protect her friends from getting burned by Delphox. Then Viola tells the Vivillons to split up and dive down to rescue the Pokémon from the stone pillars. They eventually succeed at freeing the Pokémon from the Pokémon absorber and stop Team Flares plan and defeat Delphox. As the Pokémon are cheering for them, Viola shakes hands with Yvette. Alexa, Viola, Clemont, Bonnie, Yvette, the Sky Trainer, and the Kalos Gym Leaders(except for Korrina) later go to Luminose city to deliver Shaunas Furfrou, who was one of the Pokémon they'd freed, and to congratulate X and his friend for defeating Lysander.
