Pokemon the Series: Ruby & Sapphire Season 902 Episode 1 Queen of the Serpentine

On his way to the Battle Pike and his fourth Frontier battle, Ash is initially tricked into believing that a Team Rocket front is actually the Battle Pike, and that Jessie is the Frontier Brain, Queen Lucy. But after discovering the truth and getting Team Rocket out of the picture, our heroes meet the real Queen Lucy, along with her three feisty sisters. Brock is immediately smitten with Lucy, as usual...but amazingly, she seems to return his affection! Ash challenges Lucy to a battle and quickly discovers that her strategy is entirely focused on defense. This turns out to be Lucy's undoing, as Ash comes up with a strategy that beats Lucy at her own game. After receiving the Luck Symbol, Ash takes leave of Queen Lucy and the Battle Pike, but not before Brock says his heartfelt goodbyes to his latest flame. It appears that the two of them have truly stolen each other's hearts...
