Malva

Malva ( パキラ   Pachira) is the Fire-type Elite Four member in Pokemon X and Y.

She is the first Elite Four member to be a villainous team member, and also the first to be considered a villain in the games (the Kanto and Johto Elite Four members are not villains in the games).

Description
Malva is a news reporter and a self-proclaimed Holo Caster star. She is also a member of Team Flare, where she seems to be at least Admin-ranked, and rigorously defends their actions. She has a bad temper and.expresses hatred for the player character, talking down on their defeat of Team Flare and even threatening to kill them.

Malva is first seen announcing a news bulletin at the Poke Ball Factory, discussing Team Flare's invasion of the factory without giving away their names.

After the player character defeats the Elite Four, Malva forces the player to fight her at the hotel in Lumiose City. Once she is defeated, she reveals that she had left Team Flare because she disagreed with Xerosic about creating the Expansion Suit and its use on a child. Malva agrees to help and then directs the player to where Xerosic is hiding so he can be turned in.

Despite Malva's involvement with Team Flare, there is no indication that Diantha or the other Elite Four members were aware that she was a member.
