Ash, Goh, Korrina, and Gurkinn move to the top of the Tower of Mastery, where Korrina hands Ash a pair of Mega Gloves, with a Key Stone embedded in one of them. Ash puts them on and admires his new Key Stone sparkling in the sunlight. Ash’s Lucario suddenly becomes surrounded in an Aura, which Goh mistakes for Lucario being about to Mega Evolve. Gurkinn corrects him on this, explaining that Mega Evolution requires the Trainer to hold a Key Stone and the Pokémon to hold a Mega Stone. Each Pokémon capable of Mega Evolving has its own Mega Stone, with Lucario’s Mega Stone being called the Lucarionite. Lucario walks to the edge of the balcony and points towards the sea. Gurkinn says that Ash’s Key Stone has enhanced his Lucario’s Aura, and Korrina realizes that it’s pointing towards Mega Island.

The group gets on a boat, where Gurkinn explains that Lucario had sensed the location of its Mega Stone. As they approach Mega Island, Korrina and Gurkinn explain that it suddenly appeared one day and was given its name due to the large number of Mega Stones found on it. Because of this, many Pokémon capable of Mega Evolving are also present on the island, making Goh excited. When they make land, Gurkinn stays at the boat, while Ash, Goh, and Korrina move on to go find a Lucarionite. They soon spot a shine inside a cave and run after it. They soon realize, however, that the shine was coming from the eyes of a Sableye instead of a Lucarionite, just in time to slip on a frozen hillside and start sliding down towards a ravine. Lucario manages to grab the edge of the cliff with the spikes on the back of its hands and grab Ash with its legs, while Ash grabs onto Goh and Goh grabs onto Korrina. Pikachu retrieves Dragonite and Flygon’s Poké Balls and calls them out to pick up the group. While flying to safety, the group notices an Abomasnow on the other side of the ravine and realizes that it was the one who had frozen the hillside.

The group continues to move further into the island. Just as Ash asks Lucario if it can sense where exactly its Mega Stone is, they notice a Salamence and a Pidgeot battling in the air above them. Pidgeot’s Gust causes everyone to fall off Dragonite and Flygon and onto the giant lily pads below. The giant leaves bounce Ash and Korrina up and down, while Goh and Lucario are sent bouncing further and further away from one lily pad to another, with Flygon following them. Deciding that flying is too risky, Ash recalls Dragonite before he and Korrina head after Goh and Lucario.

Goh and Lucario, meanwhile, land in the middle of a rocky area filled with erupting pillars of lava. While recalling Flygon, Goh notices that Lucario is having trouble withstanding the fiery environment due to being a Steel type. To solve the problem, he calls out Panpour and has it use Rain Dance, creating a rain cloud over them as they try to get out of the area. On their way out, Goh spots a Camerupt in their way and catches it, and has Cinderace knock down a lava pillar with Pyro Ball. They eventually make it to a cooler environment, where Goh thanks his Pokémon for their help before recalling them.

Their first job together is brushing a rich man’s herd of Tauros. After successfully carrying it out, they next head to Rock Tunnel to rescue another Trainer’s Tauros from being lost in the darkness. Although Grookey’s actions cause the Tauros to rampage, he is still happily reunited with his Trainer. Meanwhile, Team Rocket is at a park, trying to think of a plan to steal the rich man’s Tauros herd. While thinking of it, Jessie goes to a drinking fountain to get a drink, but the fountain accidentally breaks and springs a big leak. Meowth, noticing Devi speaking about her handyman job nearby, calls on her help. She gets nervous, but manages to calm herself down before attacking the problem. With Ash and Goh’s help, she’s able to fix the fountain and stop the leak. Despite her good work, however, Minun still remains grumpy towards her. The rich man then calls again, requesting for them to come look after his Tauros in an hour. Multa hands the disguised Team Rocket a leaflet about her company before leaving. Looking at it, Jessie gets an idea on how to steal the Tauros.

When Multa, Ash, and Goh arrive at the rich man’s house an hour later, they’re surprised to find out that he just handed his Tauros to another group of handymen. Following the description they receive, they locate Team Rocket, disguised as handymen themselves. When they start acting suspiciously, they remove their disguises and perform their motto, before making a run for it. However, in their rush, they end up running over some unstable planks placed on top of a uncovered manhole, causing pokemon brilliant diamond pokedex Meowth and the bag containing the Tauros to fall into it. Some of the pokemon showdown Taurosemerge from their Poké Balls and fall on Meowth, leaving him trapped.pokemon journeys season 2
