Elizabeth's Primarina

Elizabeth's Brionne was the first Pokémon Elizabeth Storybook obtained on her journey as a Pokémon Trainer, given to her by Professor Kukui.

History
In the first episode of Pokémon Storybook, The Mystery egg, Elizabeth sprinted to Professor Kukui's Laboratory, eager to get her first Pokémon. She chose Popplio, and the two of them immediately went to do some battles against wild Pokémon.

Popplio's first battle was against a wild Caterpie. She won, but the next battles was not so lucky, against a Cottonee.

Not knowing that Water types are weak to Grass types, Elizabeth thought Popplio was dead and that she had failed as a Trainer, which wasn't true as she was told that it was just fainted and took it to the Pokémon center.

Some time later, Popplio evolved into Brionne and Elizabeth left it at Storybrook Village Laboratory for a long time until Brionne is back, when she decided to have it in her party again and asked Rotom to send it to her.

Personality and characteristics
As Elizabeth's first Pokémon, it was good friends with Elizabeth's Minccino from its hatching until its release, playing together with stuffed animals. It is relativley happy-go-lucky and blithe, clapping whenever Elizabeth achieves something like catching a Pokémon or winning a badge. As mentioned by Elizabeth, every time she looks at Brionne, she has a flashback of Cinccino, due to its association with it as a Minccino.
