Movie
Description
Serena's Braixen started as a Fennekin, chosen by Serena from Professor Sycamore in Lumiose City. As a Fennekin, she mirrored Serena's habits like stretching together, displaying a friendly yet bold personality. She strongly disliked getting dirty but conquered this aversion to protect her trainer, notably unleashing Ember to scare off a wild Vespiquen early in their journey. Her protective instincts drove her to battle Team Rocket multiple times, mastering Flamethrower and Hidden Power during these confrontations.

Fennekin joined Serena in diverse activities, from PokéVision videos to Poké Puff contests. She faced setbacks, stumbling during her first Pokémon Showcase performance. Witnessing Aria's Braixen in a Showcase ignited a shared commitment with Serena to become Kalos Queen. Fennekin evolved into Braixen mid-battle against Aria's Delphox, her determination to shield Pancham from an attack triggering the transformation.

As Braixen, she maintained her affinity for cleanliness and performance but developed a profound attachment to the twig in her tail, a symbol Serena linked to their Kalos Queen goal. Pancham accidentally shattered this twig during practice. Braixen rejected all replacement attempts, prompting Serena to seek help from woodcraft expert Woodward. In a battle against Woodward's Gallade, Braixen's intense emotions transformed her Flamethrower into the powerful Fire Blast. Woodward observed her excessive attachment to the twig was harmful. After it broke completely, she finally accepted a new twig offered by Pancham, mending their bond. Serena adorned the new twig with a bow as a keepsake.

Braixen shared a close bond with Serena and forged an initially contentious but evolving friendship with Pancham. Early conflicts stemmed from minor disputes, but reconciliation after the twig incident led to collaborative performances. Her battling style featured fire-based moves like Ember, Flamethrower, and Fire Blast, alongside non-fire techniques such as Scratch and Hidden Power.

Later, while training for Pokémon Contests in Hoenn, Braixen evolved into Delphox, demonstrating heightened confidence and maturity during her performances.
