This is one of the few episodes storyboarded by executive producer Kunihiko Yuyama.
A Togepi Mirage! (Japanese: 蜃気楼の彼方に！トゲピーの楽園！Other Side of the Mirage! Togepy's Paradise!) is episode 45 of the Advanced Generation series, and the 319th episode of the Pokémon anime. It was first broadcast in Japan on October 2, 2003 and in the United States on October 2, 2004.
Shedinja attacks Misty and friends, but they are protected by Togepi using Safeguard. Everyone is then transported into the Togepi Paradise, located inside the mirage floating above the temple. There they find a group of sick Togepi. It is explained that Togepi are only well based on the emotions of those around them, and the evil plotting of Colonel Hansen is making them sick.
Colonel Hansen tries to break into the Togepi Paradise, and Misty's Togepi travels back to try and stop him. Instead Togepi is knocked out by Hansen's Shedinja and Ninjask. Misty and everyone else are transported back to the Mirage Kingdom.
Back at the palace Hansen claims the throne, and has the king imprisoned. He kicks Team Rocket out. A ceremony begins in which Hansen is declared king. Outside, Team Rocket disguise themselves as fortune tellers to tell Brock where the king is being held.
Ash, May, Misty, and Princess Sara confront Hansen at the palace, but Torchic and Pikachu are no match for Ninjask and Shedinja. The other Togepi suddenly emerge from the Togepi Paradise and channel their energy into Misty's Togepi, using Safeguard to protect everyone. Misty's Togepi evolves into a Togetic.
Misty throws out her Gyarados and uses Flamethrower to roast all of Colonel Hansen's Pokémon. The king arrives and has Hansen arrested. Togetic decides to stay and protect the Togepi Paradise. All of the Togepi leave, except for one who jumps into Sara's arms. With that Togepi, the princess can now claim the Mirage Kingdom throne.
Everyone bids Misty goodbye as she heads back to Cerulean City aboard a zeppelin.
Pikachu's cheeks are sparking with electricity as Colonel Hansen orders his Pokémon to attack. His two Ninjask use Hyper Beam while Shedinja unleashes a Solar Beam at the group. Misty watches as Togepi protects everyone from the attacks with a Safeguard. After that, Ash, Misty, and the others disappear, much to Colonel Hansen's dismay. They find themselves in a mysterious dimension, which Miranda calls the Togepi Paradise. She explains that the Mirage Kingdom and Togepi Paradise help to protect each other, but she is sad to say that a lot has changed since the last time she was here. Misty's Togepi leads everyone to some injured Togepi. May consults her Pokédex for a solution which details that Togepi has the ability to sense people's hearts, but its power will be weakened if it senses impurity in a Trainer. Hansen and his Pokémon manage to break into the Togepi Paradise, a feat which does not go unnoticed by Ash and the others. Togepi then floats towards Hansen, much to the surprise of everyone. With Togepi in his grasp, Hansen makes his way towards the palace to demand the throne from the King. When the King refuses, Hansen sends the reigning monarchs to the dungeon.
Misty is left fuming and attempts to break through the time-space barrier to the Mirage Kingdom. The weakened Togepi use their power to assist the group in returning. Later, as they make their way through town, Brock leads the discussion and states they have to defeat Colonel Hansen's Bug Pokémon. May replies that her Fire-typeTorchic would be perfect. Suddenly Jessie appears on a broadcast screen to announce that Colonel Hansen is now the Mirage Kingdom's regent. Miranda and the townspeople are a gasp, and Princess Sara is now deeply concerned for her parents. Meanwhile, Team Rocket's attention turns to their reward, but Hansen declares that he has no need for them anymore. The Rocket think it is a cruel joke, but realize Hansen has betrayed them after orders his Pokémon to send them blasting off.
Ash's Taillow and May's Beautifly conduct an aerial search of the palace, but report back without any news. Miranda advises the group that the King and Queen are likely being kept in the tower, so Brock suggests they break into the palace. Ash, Misty, May and Princess decide that they will rescue Togepi while the others will search for the Sara's parents. As Brock and the others look for the King, two fortune tellers, who are actually Team Rocket in disguise, informs them of the King's location. After that, Team Rocket disappears with their revenge on Hansen for betraying them complete. Miranda says she’ll lead Max and Brock to the hinted location.
Meanwhile, Colonel Hansen arrives at the coronation temple with Togepi in hand, and the priest officially declares him the new monarch of the Mirage Kingdom. He leaves the complex and orders Togepi to use Metronome to open the portal to the Togepi Paradise, however Ash and the others arrive to stop his plans. Colonel Hansen refuses to listen and instead orders his Pokémon to attack. May sends out Torchic, but she quickly recalls it after it is hit by a Shadow Ball. Pikachu, however, manages to knock out both Ninjask with a Thunder attack. As Shedinja charges up a Solar Beam, a Safeguard intervenes, with the defenses source revealed to be the Togepi from the Paradise. The Paradise Togepi perform a Metronome and bestow a mysterious blue light on Misty's Togepi. Next, Togepi bursts with blue energy before evolving into Togetic. Ash and the others look quite bewildered by Togetic's new form. It flies up to the Paradise Toegpi and protects them from an oncoming Solar Beam, which irritates Colonel Hansen. Togetic causes the area to flare with bright white light. Misty smiles and tells Togetic to leave everything to her. She takes out a Poké Ball, kisses it, and calls out Gyarados. Hansen is not fazed one bit, knowing that Gyarados's Water attacks are useless against his Shedinja. Misty does not back down and confidently orders Gyarados to use Flamethrower. The attack deals great damage to Shedinja, finally knocking it out. While everyone wonders why Gyarados can use Flamethrower, Misty states that Water Pokémon can learn Fire attacks too. The King and Queen, with their guards behind them, confront Hansen and he sent to the dungeon for his treachery. Team Rocket spy from a rooftop and pleased to Hansen being taken away.
Later the Togepi appear cheerier than before and return to the Paradise. Togetic informs Misty that it wishes to stay behind in the Paradise and become its protector to prevent people like Hansen from causing harm. Misty and Togetic share one last tearful moment before bidding each other farewell. As Togetic enters the Togepi Paradise the sky mirage fades. Princess Sara assures Misty that she will protect the Paradise and Togetic from harm. Something is tugging at the Princess's dress, and Sara is surprised to see a Togepi. She is happy, because not only does she get a Togepi, but also she is also eligible to become the new ruler. Later, as Misty prepares to return back to Cerulean City and resume her Gym Leader duties, she wishes everyone the best of luck with their endeavors and invites them to visit her sometime. Ash and the others wave to Misty as she leaves back to Kanto in a blimp.
When Misty is saying goodbye to Togetic, the shading on the cast and the archway are inconsistent.
At one point, Togepi is hit by Shadow Ball, even though it was a Normal-type at the time that this episode aired.
Shedinja's missing halo
In the Hindi Hungama TV dub of the anime, Ash doesn't seem to wonder how Gyarados was able to use a Fire-type attack being a Water-type Pokémon itself, but simply feels amazed and congratulates it for knocking out Shedinja rather effortlessly.
