Lysandre sent Mienfoo to intimidate Tierno, Shauna and Trevor, wanting to see pictures Trevor took in Vaniville Town. Fortunately for the kids, Diantha arrived with her Gardevoir, claiming Lysandre has frightened the children too much.
After X infiltrated Team Flare's headquarters, he faced Lysandre and sent his Marisso to battle Lysandre's Mienfoo. To continue his battle against Lysandre, X called his Quilladin and Charmeleon back and sent Manectric, Gengar and Kangaskhan. Mienfoo used Dual Chop to attack. After Shauna, Tierno and Trevor arrived to Lysandre's chamber, they noticed Lysandre, Mienfoo, Mega Gyarados and Pyroar, who managed to defeat X and his Pokémon.
