The Dragon Master's Path! (Japanese: ドラゴンマスターへの道！！ キバゴＶＳクリムガン！ Axew VS Druddigon! The Road to Become a Dragon Master!!) is the 30th episode of Pokémon: Black & White.
While on the way to Nimbasa City, Ash and Iris decide to have a battle and encounter a Druddigon and it's trainer, a young girl named Emmy. When Ash decides to battle her, the group sees the problem: Emmy doesn't have any experience handling a Pokémon like Druddigon. To make matters worse Team Rocket has made off with both Druddigon and Axew. Will Iris and Emmy get their Pokémon back?
Iris and Ash have another battle. Axew goes to scratch, but misses and gets headbutted by Scraggy. Axew uses Dragon Rage, but, as always, it fails and explodes, hitting everyone. Cilan tells the Dragon Sneeze failed again, but Iris is annoyed, as it is Dragon Rage. Ash thinks Axew is just struggling to learn, though Iris gives Axew some rest, knowing he'll master Dragon Rage eventually. Ash calls Scraggy back and soon they get attacked by Flamethrower. Iris recognizes the Pokémon to be Druddigon, admiring this dragon. Suddenly, Druddigon uses Focus Blast, so Pikachu counters it with Electro Ball. Suddenly, a woman appears, trying to calm down Druddigon, who runs off, so the heroes follow it.
Ash, Cilan and Emmy catch up to Iris, who shushes them. Axew climbs up to a cave and enters it, then runs out, terrified. Druddigon comes down and yells out, so Iris unties a rope binded on its leg. The woman is surprised, wondering if someone did this. The woman thanks them for the help and introduces herself as Emmy. Iris tells she knew Druddigon cannot move if its body temperature is low and would hide where the sun shines. Ash sees Iris knows a lot about Druddigon, so Iris reminds him she grew up in the Village of Dragons. Team Rocket is surprised Druddigon cut through their net, but are pleased for they can capture it, as well as Axew and Pikachu.
Iris admires the Dragon Masters, the ones that bring full potential of Dragon Pokémon out. Iris tells she wants to become a Dragon Master, so they see why she knows so much about dragons. Emmy asks Iris to be taught more, as she received Druddigon and is a new trainer that will soon go on a journey. Iris accepts and thinks a battle might be a good start. Emmy hesitates, but Ash recommends her to battle him, for she can bond with Druddigon. Ash sends Tepig, who tackles Druddigon. Iris advises Emmy to be calm and order a move. Druddigon uses Focus Blast, though Tepig dodges and uses Flame Charge, though Druddigon blocks the attack. Druddigon uses Dragon Claw and dodges Tepig's Ember. Using Dragon Claw, Druddigon defeats Tepig.
Emmy thanks Iris, who advises her to never give up and trusts the dragons. Ash calls Tepig back, while Iris asks Emmy what other moves Druddigon knows. Emmy admits no other, so the heroes think Druddigon should learn one more, as it would be a different game. Emmy accepts the challenge. Suddenly, Yamask uses Shadow Ball, hitting Druddigon. It does so once more, but Druddigon dodges. Druddigon goes to use Flamethrower, but a Woobat uses Gust. Axew, Pikachu and Druddigon get caught, though Druddigon uses Dragon Claw to slash the rope that binds Pikachu. They get boarded on Team Rocket's airship. Iris is insulted, for Axew is caught, so she speeds up to catch onto the airship, but fails. Team Rocket plans to evolve Axew to take over Unova. Woobat gusts away the twerps, while Yamask uses Shadow Ball on them.
Team Rocket departs away, pleased they caught the dragons. Druddigon uses Dragon Claw to get out, but James lets Jessie and Meowth know the airship is hard enough not to allow any escape. The heroes speed up, while Iris remembers the Elder, who told her about the experiences Iris will receive on the journey, though Iris promised she and Axew will do their best. She speeds up, while Druddigon tries to get out. Axew uses Dragon Rage, causing the airship to be damaged and to crash. Druddigon breaks out, though Team Rocket thinks they won't get far. Iris climbs up a tree and hears Axew and Druddigon face Woobat and Yamask. She runs off, though Cilan and Emmy tell there is a faster way. Ash decides to trust Iris on this, so follows her, along with Cilan and Emmy.
Druddigon and Axew slip down, though are unharmed. Druddigon uses Dragon Rage on Team Rocket, who evade. Yamask uses Shadow Ball, which Druddigon blocks, though gets blown away, along with Axew, by Woobat's Gust. The heroes came to the dragons, though Yamask uses Shadow Ball. Pikachu uses Thunderbolt, canceling Yamask's attack and hitting it and Woobat. Druddigon and Axew come back to Emmy and Iris. Yamask uses Night Shade, affecting Emmy and Druddigon, knocking them down. Druddigon uses Draco Meteor, and with Emmy's order, releases it, causing a major blast that defeats Yamask. Woobat uses Gust, but Pikachu uses Electro Ball, hitting Woobat. Axew uses Dragon Rage and manages to control the attack, hitting Team Rocket with it. However, Team Rocket retreats, flying off in their jetpacks.
Iris hugs Axew, for he finally learned to use Dragon Rage properly. Emmy is also convinced to start her journey. Iris plans to become a Dragon Master, while Ash is also training hard to be a Pokémon Master.
The "Who's That Pokémon?" is Druddigon.
