Black Braixen
Black Braixen's story started when Ash and Bonnie flying to Kanto in the same plane, Ash was returning home after losing Kalos League and Bonnie was heading to Professor Oak's Pokémon Camp, she was worried because this was the first time she traveled without Clemont, but Ash cheered her telling her how he met Serena at the summer camp and how she could make friends there, after the landing Ash returned to his home at Pallet Town while Bonnie tok the bus to summer camp at the airport.

At the summer camp she was walking through the forest when suddenly she heard a little girl abour her age screaming behind the bushed, it was one of the campists who was alone and being threatened by a Mankey at the forest, Bonnie scared it with Dedenne and then it left, she asked the little girl if she was OK and after telling her name and then she said her name was Olivia. Bonnie was surprised that Olivia was very similar to her friend, Serena who became the new Kalos Queen, Olivia didn't know anything about Serena and the tripokálons so after Bonnie explained her which lead to Olivia wanting to go to a Pokémon showcase after the camp and start getting interested in tripokálons.

The P-Squad: Operation Hypno
Despite Bonnie doesn't appear in Operation Hypno, Olivia started talking about her as Prism Tower's gym leader during the P-Squad's mission briefing when she asked about Team Rocket's possibilities to hurt her if she was there or take advantage of her possible absence, Hagar explained that TR discussed how to enter the tower in case she was there, they talked about entering at midnight or trying to overpass her by any way which in part lead the team to Kalos as quick as possible.

During the mission Olivia entered the tower to check if she was in time to warn Bonnie about the attack, but one of the screens turned on with a message from Bonnie saying she was not at the gym because she was out of the city.
