The Green Guardian.A lightning storm causes a forest fire, endangering all the Pokémon of the forest. The Legendary Pokémon Celebi appears to stop the fire and saves the Pokémon. Seeing a falling tree about to hit it, it teleports away to a different time and hides by creating vines around it. On their way to the Battle Pike, Ash and friends decide to ride along Cycling Road. However, it is closed and they take a detour through the forest below. After hearing a noise, Pikachu runs off into the forest and finds the injured Celebi under some thick vines. Trying to find Pikachu, Ash and the others run into the Pokémon Ranger Solana who agrees to help them find Pikachu. Solona uses her capture styler to temporarily capture wild Pokémon to help with travelling through the forest. While searching for Pikachu, the group finds Team Rocket stuck in some vines and frees them and then run off. When they finally find Pikachu and Celebi, the reunion is short-lived as Team Rocket attacks, wanting to capture Celebi for themselves! After a short battle and a successful Volt Tackle from Pikachu, the group defeats Team Rocket but their robot causes another fire. Celebi again stops the fire and then returns to its own time. Ash and friends continue their journey, finally able to use the Cycling Road.
