Pokemon the Series: Ruby & Sapphire Season 902 Episode 9 Curbing the Crimson Tide

On their way to Ash's next Battle Frontier challenge, our heroes take a sightseeing tour of Commerce City, where they learn of a mysterious talking Pokemon named Red Lightning, who has been challenging and terrorizing Trainers all over town. Vowing to get to the bottom of this, our heroes eventually find their way to the skyscraper mansion of Luna, Red Lightning's Trainer, and discover that the mysterious "talking" Pokemon is actually a Scizor in disguise, equipped with a microphone. Luna is utterly shocked when Ash defeats Red Lightning with his Sceptile, and our heroes learn that she's a lonely girl whose famous inventor parents are rarely around and who plays tricks on people so they'll pay attention to her. May offers to take her on in a real Pokemon battle, and though Luna loses again, she has so much fun that she promises to battle honestly from now on and stop making mischief.
