In Pokemon the Series season 17 episode 1, titled "Kalos, Where Dreams and Adventures Begin!," viewers are introduced to a new region in the Pokemon world: the Kalos region. Ash and Pikachu have arrived in the region, eager to explore and encounter new Pokemon.

The episode begins with Ash and Pikachu taking a train into the Kalos region. As they ride, they notice the beautiful scenery passing by, including mountains and fields of flowers. They also spot a mysterious Pokemon flying by the train, which Ash immediately wants to catch.

Once arriving in the Kalos region, Ash and Pikachu head to the Lumiose City Pokemon Center where they meet a new character, Professor Sycamore. Professor Sycamore is a friendly professor of Pokemon and the one who helps Ash in his journey by giving him his first Kalos Pokemon, a Froakie. Ash is thrilled to have a new Pokemon and is immediately determined to train and battle with Froakie.

Meanwhile, we are introduced to a group of new characters, including a girl named Serena, who recognizes Ash from when they were both younger.

We also meet a boy named Clemont and his sister Bonnie, who are both fascinated by technology and robots.

As Ash and Pikachu explore the city, they come across a gym and Ash immediately wants to challenge the gym leader and earn a badge. However, the gym leader, Clemont, isn't interested in battling and instead challenges Ash to a gym puzzle. Ash accepts the challenge and must solve a series of puzzles in order to earn the badge.

Along the way, Ash and his friends also encounter a group of mischievous Pokemon called Spritzee and Swirlix who have stolen Serena's handkerchief. Ash and Pikachu help Serena retrieve her handkerchief, and in return she promises to help them get to know the Kalos region better.
