Ash and co. meet Alder in person for the first time, Ash and co. run into Trip who has five badges now. Alder challenges Ash to a battle but falls asleep during the battle, meaning there was no winner.
Just as they were about to leave Nimbasa City, Ash and co. meet with Trip again, who has five badges over Ash's four. Later they meet the Unova Champion Alder, the man who inspired Trip to be a Pokémon trainer when he was a kid, only to see that now, he's a goofy guy. He challenges Ash to a battle and Ash gladly accepts. Who will win this battle? And what in the world is going on in Alder's head anyway?
Though Ash has befriended old Champions like Johto's Lance, Hoenn's Steven Stone/Wallace and Sinnoh's Cynthia, this is the first time Ash battled a champ other than his rival Trip's wishes too.
