Ep 5. Overjoyed!

When our heroes and Brandon arrive at the Battle Pyramid for Ash's final Battle Frontier challenge, they meet Nurse Joy, a big fan who knows absolutely everything about both Ash and May's Pokemon careers and has a scrapbook to prove it! She offers to help Ash train for his battle--and ends up beating him with her formidable Chansey, who also blasts the Team Rocket villains off as soon as they show up to steal it. Professor Oak sends Ash his Torkoal to face off against Registeel, a Legendary Pokemon who's fighting on Brandon's team, and the matchup seems to be going his way...until his overconfidence gets the better of him, and Brandon's power and experience prove too much for the young Trainer. The Frontier Brain offers some valuable words of wisdom, which Ash takes to heart, and promises to battle him again as soon as he returns from his quest for a mysterious Pokemon!
