Ep 23. Mean With Envy

Ash, May and Max are on their journey to the Battle Dome and they come across a strange girl named Brianna. Brianna seems very envious of May's Skitty and interacts strangely with it, causing Skitty to act out of character and become aggressive. When they reach the Battle Dome, Brianna is there too and she challenges May to a battle. During the battle, Skitty once again becomes aggressive, causing May to lose the battle. Ash and Max are suspicious of Brianna and decide to investigate her. They discover that Brianna has been injecting a potion into her own Pokemon to make them stronger, but it has also made them mean and aggressive. Brianna then tries to capture May's Skitty and inject it with her potion, but Ash and Max intervene and defeat Brianna's Pokemon. In the end, Brianna apologizes for her actions and promises to stop using the potion. May's Skitty returns to its friendly self and the group continues on their journey to the Battle Dome.
