Mable

Mable, known as Momiji in Japanese, is one of the five Team Flare scientists in the Pokémon X and Y games. Recognizable by her blue hair, she's a key member of the villainous team. Mable first appears in Frost Cavern, where she is seen agitating an Abomasnow with two Team Flare Grunts. The player, with Trevor's help, defeats Mable and her grunts, forcing her to retreat. Later, Mable is encountered at Lysandre Labs, preparing for Team Flare’s plan to use the ultimate weapon. After another defeat, she gives the player the Elevator Key to access the lower floors of the facility. In the anime, Mable initially helped those in need alongside Lysandre and the other Team Flare scientists, but later supported Lysandre's disillusionment with humanity and his aim to reset the world. She leads attempts to capture Zygarde and engages in battles with Team Rocket. During Team Flare’s attack on Lumiose City, Mable remains at Lysandre Labs, where she attempts to take down a helicopter approaching the lab and battles Steven. She is ultimately defeated. Mable uses Houndoom and Weavile in battles.
