Premiering in Japan on July 16, 2005, it introduced four new Generation IV Pokémon, Lucario, Bonsly, Mime Jr. and Weavile.

Hundreds of years ago
Lucario jumps from boulder to boulder to a spot overseeing a wide expansive valley. Lucario senses something and uses its Aura to see the entire landscape. Lucario lets his sight travel about, going over more rocks and hills until he sees a large formation of a gigantic, red-armored Pokémon army, mixed with human foot soldiers, that is charging towards the middle of the valley. He looks to the other side of the valley and sees an equally gigantic, green-armored army, with equally powerful Pokémon of different species charging to the same destination.
As Lucario is comprehending the danger of the event, three Houndoom from the red army arrive at the scene, which Lucario evades and leaps away. He heads to a crystal formation on the ground, touching it and then speaks through the crystal to his master, Sir Aaron, an Aura Guardian, who is at Cameran Palace. Aaron stands upon a balcony with Queen Rin that overlooks the entire land, and he hears Lucario's voice coming from another crystal formation on the balcony. It seems the palace is in imminent danger of being overrun; peace cannot be brought to the two warring sides.
The three Houndoom find Lucario and proceed to attack him. After being cornered, he is left no choice and fights back. Using his Aura to sense his surroundings, he manages to defeat his pursuers.
Knowing that Aaron must leave, Rin explains she is obliged as queen to share the same fate as the castle. After their last exchange of words, Aaron hops a ride on his Pidgeot to the valley. Aaron tells Lucario that he has abandoned the palace and the Queen and will not be returning. Lucario cannot believe what he is hearing and implores him to wait, but Aaron throws down his scepter, trapping Lucario and drawing him into the jewel at the top. From within the jewel, Lucario can see Aaron going off and feels betrayed.
Rin observes from afar that the Tree of Beginning is suffering from the hazard. The two armies clash in the middle of the valley. Outside of the tree, Pidgeot flies away alone. With this, Ho-Oh returns to the Tree of the Beginning, revealing itself to be Mew.
Pidgeot approaches Rin with the scepter in its beak, which she takes. Suddenly, Rin witnesses the sight of the tree starting to glow green, and soon every crystal formation throughout the land emits a beam of green light. As the light spreads further out, the armies stop their battle, in awe of the event that is taking place.
And with that, a mother reads the story to her daughter. According to legend, Queen Rin believed Aaron to be the hero who had used the power of the Tree of Beginning, where Mew is said to live. The two armies stopped their fighting, their hatred replaced with understanding and returned to their lands and peace was restored. Aaron became known as the True Guardian of Aura, without whom peace would have not been restored. To this day, the legend is commemorated every year in the town of Rota and the same Cameran Palace.
Ash, May, Brock and Max happen to come to this town during this time, and decided to participate in a tournament to decide who will be the "Hero of the Year." Ash and company walk along a bridge to Cameron Palace, they are dressed in their regular clothes while the others are in renaissance outfits. Meanwhile, a Taillow overhead lands on a window of the Palace, turning into a Pichu. In another room, Ash and company finds a costume closet and decide to dress more appropriately. They later hurry to the tournament that is about to begin.
Before the tournament begins Queen Ilene, the ruler of the palace along with her maid Template:Mo and her Pokémon Mime Jr., steps out to the royal box seat to officially begin the tournament. Ash and Pikachu win it eventually and Ash becomes the "Hero of the Year".
Ash goes up his opponent in the finals and is surprised to discover the trainer is actually a girl. She introduces herself as Kidd Summers. Ilene then announces that there will be a ball and banquet in honor of the "True Guardian of the Aura".
Ash is presented to sit in a throne that overlooks the ballroom. Ilene presents Ash with Aaron's scepter. He suddenly hears a voice from the jewel crying "Why?". Ash is a bit confused, he asked if someone else heard it, but nobody did. Shrugging it off, the ball soon goes underway.
With the new company, Mew transformed as an Aipom takes the Pokémon posse about through the castle. Meowth, who is helping himself to some food underneath the table, hears them and decides to follow them but is unable to. Aipom directs the Pokémon to the attic. There Aipom shows the Pokémon around to a few toys and all of them plays around with those. After a bit, Aipom transforms into Pikachu and begins dancing with Ash's Pikachu.
Kidd slips away from the ball into the same direction the Pokémon went off to. She quickly slips out of her costume, sporting a pink-purplish wetsuit like outfit. She makes her way outside from the window, Meowth noticing and follows. She climbs up to the rooftop before shooting a grappling rod to a tower across the castle grounds. She jumps off from one roof to the next. Meowth only goes so far, before he slips down the sloped rooftop. His tail grabs a hold of a decorative steeple rod, but finds himself swinging down, crashing into a window on the lower floor.
Ash sits upon the throne, being a bit bored. He asks if he could get some food but Jenny keeps him down on the throne, telling him to act like a hero. Max notices the Pokémon are missing, until Munchlax comes back to nab a plate of fruit and goes back upstairs with it. Max follows Munchlax to the top.
Kidd manages to get to a good vantage point on the roof where she can see through the broken glass Meowth made. She sees Mew and then puts on a pair of special glasses and begins reporting information to her boss, Banks.
In the attic, the other Pikachu transforms into Mew, looking at Meowth to see if he is alright. Taking this chance, Kidd sends out two Weavile, and orders them to place a tracking device on Mew. Both of them jump into the broken window and begin a swift attack at Mew. Mew dodges their assaults easily. In an attempt to stop Mew, both of them use Blizzard just as Mew flies towards the door. At the same moment, Munchlax comes into the room and finds itself frozen in a block of ice. The door also freezes at its hinges and cracks. Just when Max gets there, he finds the door hard to open.
Mew is soon held down though, and just when one of the Weavile is about to attach the tracker on Mew, Pikachu shocks the Pokémon with a Thunderbolt. Mew escapes to Pikachu, but the Weavile try another Blizzard attack. Both Mew and Pikachu dodge, the attack hitting the other Pokémon, freezing them. Mew then flies over towards Meowth who is at a corner, and transforms into a Meowth. Mew switches itself and Meowth around to confuse the Weavile, but Meowth speaks and ruins the plan. Soon Pikachu is left exhausted and weakened from battling with the Weavile.
Kidd notices this and figures that the plan did not go as well as expected. With Pikachu unconscious and the other Pokémon frozen, both Mew and Meowth are on their own. Mew transforms back to its original self. Max finally gets the door open, but only a crack as he watches what goes on. Mew soon teleports before the Weavile can do anything else. The three teleport to one of the tower's steeples, and then Mew transforms into a Pidgeot and flies off, towards the Tree of Beginning.
Back at the ball, Jenny tells Ash to stand up and do the hero's pose. Ash stands up and copies the pose on Sir Aaron poster. Once again Ash hears a voice from the jewel. The jewel soon glows, releasing Lucario from it. Lucario, still blinded from the attack from the Houndoom during the great battle, is using Aura to see and mistakes Ash's form with Aaron's due to their similar Aura.
Lucario kneels down before Ash before realizing he isn't Aaron. Lucario becomes confused at what is going on, seeing the many people. Lucario soon escapes through the crowd of people, running around through the castle. He sees that it has changed, and memories of him and Aaron soon start replaying in his mind as he walks about.
Lucario stops at a display room, which he remembers to be a bedroom. Ash, May, Brock, Ilene and Jenny confront Lucario in the room. Looking at Ilene, Lucario mistakes her for Rin and is glad to see her. Ilene says to Lucario that she is the descendant of Rin, the Queen who was reigning at the castle during his time. She goes on to explain that the memories that seem to him like yesterday, are in fact ancient events.
At the Tree of Beginning, Mew looks after Pikachu, who is resting in a bed of leaves. Meowth seems to understand what Mew is up to, seeing a large pile of toys that it has gathered. Pikachu soon recovers.
Back at the throne room, Ilene explains to Ash and company the story of Aaron and Lucario. Just then, Max runs into the room, exclaiming he just saw Mew getting attacked, and it took Pikachu and Meowth somewhere. Kidd comes out of the same door, confirming what Max saw. She also says that she saw Mew transform into a Pidgeot and took them away to the Tree of Beginning. Ilene takes them out to the balcony overlooking the land and shows them the tree. Ilene explains that the tree is actually a unique rock formation, and supposedly possesses healing powers beyond imagination. It can revive the earth and soothe angry hearts, although it requires Mew. Ash decides the only way to get Pikachu back is to go over there himself. At Ilene's request, Lucario agrees to accompany the group in their quest.
Kidd says that she wants to go too. Brock reveals Kidd has been on a lot of major adventure fronts, including deep sea diving in a sub and space travel. Brock goes crazy about how much he wanted to meet her and how it has been an honor. Kidd says that she is here for the adventure, and she has a Humvee that will get them there in no time. The next day, Kidd takes Ash and company towards the Tree of Beginning, Lucario running up ahead while Ilene and Jenny stay behind at Cameran Castle. Jessie and James hitch a ride in the trunk.
Pikachu, after waking up, sees that it is with Mew and Meowth. Mew is excited that Pikachu is awake and well, playing around with it for a moment. Meowth falls into a hole concealed in a branch stump. Pikachu goes up to and pokes his head in along with Mew. They see a long vertical tunnel with green bubbles coming up. Mew hops onto a bubble, followed by Pikachu. At another branch stump up higher, the three Pokémon come out. They walk up to the edge of the land, seeing the magnificent landscape below them.
The crew takes a break for lunch. Lucario finds some berries while he sits upon a boulder. As Brock passes out the plates to everyone a Bonsly takes one of them before he could get to it. Brock finds Bonsly below eating the lunch. Brock scolds it but this only makes it cry. May and Ash think Brock was too harsh, but Max points out that Bonsly is only using Fake Tears, and the Bonsly runs away with the food. Lucario picks up the plate, offering Bonsly a berry instead. The Bonsly runs off behind a rock, peaking behind it once in a while.
They continue to travel down to the Tree of Beginning, but they stop once more. This time, the road is littered with geysers that are erupting and then May notices something off to the side, a hot spring! They decide to stop until the eruptions subside and take a dip. Ash, Brock, Max, and their Pokémon, except Phanpy, take a swim in the hot spring.
When May comes out of the Humvee from dressing, Bonsly drops upon her head from the roof who apparently took a ride with them, so May decides to take it along. She tries to take Bonsly into the water, but the small Pokémon jumps out and hides behind Phanpy. Max explains that Bonsly doesn't like water because it is a Rock Pokémon. Lucario sits upon a rock, remembering the time when Aaron took him here. The memory was interrupted when Ash told Lucario to jump in, but Lucario simply walks off, Ash a bit annoyed by his cold attitude. May notices a strange looking plant upon rocks, Ash says that he will get it. As soon as he grabs it though, he slips and falls off. May catches the plant, which looks like a crystallized pod. Seeing as how it is a flower, they decided to plant it. But just before they do, the pod suddenly blooms and the area becomes holographic as they see a replay of Ash falling off the cliff as he was getting the plant. Kidd knows what it is, a Time Flower. She explains that it records events in the area at the time it was planted and then it can replay the scene at a later time when activated.
Night falls as they travel, and they decide to camp for the night. Ash tells everyone the story of how he and Pikachu became partners and best friends. Lucario suddenly walks away in disgust, and when confronted by Ash, Lucario tells him of his belief that humans and Pokémon could never be friends. Ash gets very angry at this, and asks Lucario why they should believe everything he says about Sir Aaron anyway. Lucario asks Ash how does he know Pikachu was kidnapped, maybe it just wanted to get away from a weak trainer. This pushes Ash over the edge and he tackles Lucario, both rolling down a ledge to a pond. The two thrash about in the pond, the others coming to try and stop the two from frighting. Lucario finally throws Ash out to the shore, jumping off to the top of the ledge. He storms off thinking that people are just cruel.
Lucario finds a tree to lean upon, recalling another memory of how Aaron trained him to master his Aura. Just then, Max comes up and gives Lucario a bar of chocolate who, after some hesitation, decides to eat it. Later that night, Mew and Pikachu play about while Meowth sleeps. Pikachu smiles a bit, but it still cannot help the feeling of being separated from Ash.
Ash wakes up from his sleep, thinking he heard Pikachu's voice. He gets out of the Humvee the crew was sleeping in, noticing Lucario on a rock. Ash tries to help Lucario look on the bright side of things as he tells Lucario that he and Pikachu are friends. Lucario tells Ash that Aaron was his master and cannot quite understand the concept of being alongside a human to be friends after all this time of being a servant of Aaron.
The next day, they travel down the path, soon coming up to a stop. Lucario stands looking up at a cliff, the others wondering what is going on. Lucario tells them this was the spot that Aaron sealed Lucario in his scepter. He touches a Time Flower by accident and soon it replays the exact same scene, when Lucario meets up with Aaron, where he renounces his loyalty to the Queen, throws his scepter down and seals Lucario in the jewel. Then they watch Aaron fly off. Suddenly from the two pathways on the road, the green army charges through the small pathway. Lucario appears horrified and begins throwing Aura Spheres at them, barely missing Ash. Ash tells Lucario to stop because they are only illusions. Lucario does stop, shocked to have seen that event happen. Ash comes up to him, apologizing for his earlier words against him. Lucario accepts the apology, and makes Ash promise to never abandon Pikachu.
As they walk back to the Humvee, Lucario senses something. At the last second, he pushes himself and Ash out of the way just as a Regirock digs its way from the ground. It begins using Hyper Beam upon the "intruders". Lucario covers for them and keeps Regirock occupied before escaping into the crevice. Along the way Lucario tells them to make a turn at a tunnel. They follow the tunnel, and by now it seems as if they have lost Regirock. At the end of the tunnel, they come to a large cave of ancient Pokémon.
Now that they made it into the Tree, the only way to get to Pikachu is by going up. Ash goes on ahead to another tunnel, followed by Lucario. Kidd takes out her specs, relaying information back to the company. Banks tells here that the tree is designed with many tunnels that make a network like blood vessels. Kidd deploys out small helicopter gadgets to gather information about the Tree, then she follows Ash.
The probes that Kidd deployed attempt to take samples of the crystal that lie there. However, a red blob engulfs and eats them. Kidd gets a warning that the probes are rapidly being destroyed, and that a sort of immune system in the Tree has been activated, which seeks out and destroys intruders. A Registeel becomes aware of the intruders and begins to hunt them as well.
At the end of the next tunnel, Ash finds himself upon one of the "leaves" of the Tree. Ash called out to Pikachu, who hears him and calls back. As things seemed to turn for the better, a Regice stands in front of Ash's path and begins firing a barrage of Ice Beams. Lucario battles it while Ash gets away. He gets to the tunnel, telling the others they must find another way because Regice is up ahead. Lucario throws an Aura Sphere at it to stun it long enough to get away.
They find another tunnel, finding themselves at the cliff of a large hollow cave, being a good ways above the ground. Blue crystal pillars stick out from wall to wall. Deciding where to go, Jessie and James find themselves in the same place, at a different entrance. They jump down to Ash and company, landing with a crash. Apparently Regirock and Registeel found them. Lucario pointed a way, across one of the blue pillars that ran like a bridge to another exit higher up. Lucario at the end of the line finds the Regis on their tail. He sends a Aura Sphere to the bridge, destroying it before they have a chance to cross.
As Jessie and James run up ahead, a red blob comes from the other side of the tunnel after them. It turns into a Cradily shape and swallows up Jessie. James tries to save her by sending out Cacnea, using Pin Missile. However Jessie is eventually swallowed up. Another comes after James, who sends out Chimecho, telling it to save itself. Ash and company arrive and see this, wondering what is going on with this place.
One more, in the shape of an Aerodactyl comes after them, but Lucario destroys it with his Aura Sphere. The gang are quickly on the run again, and Cacnea and Chimecho are left standing sad and confused over what happened to their Trainers. Soon the red blob figures come from behind. The others try to find another way to get past them. One of them makes it through and almost catches Kidd, that is until Lucario gets in the way. It takes Lucario, but soon explodes off. Apparently the Tree does not consider Pokémon hostile.
They soon discover the two Regis are once again behind their tails. As they run, they find a room with two tunnels. The group decides to split and meet up later. Ash and Lucario go in one group to lure the Regis away. Ash stays behind though so that he can get the Regis' attention once they have come. Using Grovyle and Corphish, he is able to slow them down briefly.
While the four travel through the Tree, the red blob strikes once more. This time, it takes Brock. Not wanting his Pokémon to go down with him, he releases Forretress and Mudkip. Max also gets caught, and May tries in vain to save her brother. After he is taken May is also taken as well, releasing Combusken, Munchlax and Squirtle before she is gone. Kidd, on the other hand, dodges two of them, managing to escape the blobs. The Pokémon are left behind, horrified by what has happened.
Lucario and Ash managed to lose the Regis but they come up to a huge crevice with the crystal pillars coming out from side to side. Not only is it a long way down, but there is a very strong wind. On the other side, Pikachu, Mew, and Meowth come out from another tunnel. Ash, happy to see Pikachu, walks out on the pillars while Pikachu does the same. Pikachu has no problem hopping from pillar to pillar in the wind, but Ash occasionally slips. He continues on when the wind gets too strong. Both him and Pikachu meet in the middle, where they jump to meet, though they soon fall down. In the nick of time, Kidd uses her grappling hook to swing across and grab Ash and Pikachu, heading to the tunnel where Lucario waits. It seems Lucario is beginning to understand the deeper relationship that could be possible between humans and Pokémon. Mew joins in, along with Meowth.
While going through the tunnels, Ash and Meowth are horrified to learn their friends are gone when they come up across the red blobs once more. They find a branch off to another tunnel but the blobs continue right behind them. The group comes to a room with large crystal formations. Lucario goes on ahead, but is ambushed by Registeel and Regirock. Registeel grabs him, giving the red blobs a chance to capture Kidd and Ash. As Kidd gets "eaten", she releases both her Weavile from their Poké Balls. Lucario desperately tries to free himself, but it stunned by Registeel. Ash releases Phanpy and Swellow and tells Pikachu to look after the others. Pikachu, desperate to save Ash, grabs onto his hand and is assisted by the other Pokémon and is horrified by what is happening to Ash. Lucario manages to free himself from Registeel's grip and hurries to help, but it is too late. Ash is gone as the blob slips into the ground. Ash's Pokémon, devastated by their loss, begin to cry. Lucario watches this, appearing hurt by the loss as well.
Mew sees how upset Pikachu is from losing Ash and flies up, touching a crystal. It begins to glow green, as well as every crystal in the area. Soon the blobs, now green, form up into mounds and dissolve away, leaving their victims behind alive and well just where they had taken them; all happily greeted by their Pokémon. As Ash is also released from the blob, Pikachu jumps into his arms and quickly followed by Ash's other Pokémon, all overjoyed to have him back. The Regis walk off, not seeing them as a threat anymore. Meowth tells Ash that Mew communicated to the Tree and was able to convince it the humans were not a threat. Ash thanks Mew for saving them, but Mew is now very weak.
Suddenly all of the crystals become red in color. Meowth hears James's voice nearby and hurries off unnoticed. Kidd's boss says that the immune system has gone into shock and whole Tree has become unstable. Kidd tells Ash that Mew and the Tree and connected and if the Tree is destroyed, Mew will certainly die. The crystals also begin to blacken and crumble, the place is collapsing, and fast. Ash gets his Pokémon back inside their Poké Balls and, with no time to lose, Mew helps him and Kidd find the core room where they could use Mew to restore the Tree. The problem is that they do not know how to restore the Tree, and Mew is too weak to do anything. Lucario looks to the side and notices that there is a crystal formation with Sir Aaron's body inside it!
Lucario does not understand why Aaron is here, but sees his gloves nearby. Ash finds a Time Flower next to the core and runs up to it to activate it. When the pod opens up, it displays the scene as Aaron comes in. Ho-Oh also comes in, revealing itself to be Mew. They watch as Aaron begins delivering his Aura, the only energy that would suffice, to Mew. Mew stores the power and once enough has been stored, goes to the core to begin the restoration. But at the end, they see Aaron stumble and fall and the scene ends.
Lucario realizes that Sir Aaron did not abandon the kingdom, but in fact sacrificed himself to save it and that he is truly the hero everyone believes him to be. Lucario is filled with guilt for doubting his master, but realizes that the power of the Aura can restore the Tree. Lucario, seeing how he can utilize the Aura that Aaron can, declares he will be the one to do it. Lucario goes up to Mew and begins transferring energy, but is soon pulled back. He realizes he is not strong enough yet to deliver the energy needed. Ash remembers that Lucario mentioned he had the same Aura as Sir Aaron, and can control it as well. He puts on Aaron's gloves, which help to channel the energy. Kidd tries to stop Ash, telling him he would be sacrificing himself, but Ash knows that if the Tree is not saved Mew and all the other Pokémon living in the tree will die. Both Lucario and Ash begin channeling energy into Mew. As time passes and they channel more energy, it begins to strain them. However at the last second Lucario pushed Ash out of the way, telling him not to worry.
Once the energy channeling was complete, Mew swiftly moved to the energy core of the Tree, the stored energy releasing a green light like the same light from the hundreds of years ago. The crystals turn green and emit bright beams of light across the land, saving the Tree and all the Pokémon.
After Mew completed the healing process, Kidd confers with Banks and finds out that everything is normal. Back in the core of the Tree Lucario stumbles down, exhausted from what he has done, in the same condition as Aaron when he collapsed. Lucario's hand bumped into a Time Flower, activating it. This time it was Aaron as he sat there, saying his last words. He tells Lucario that he only sealed him up because he knew Lucario would follow him no matter what otherwise. He also says that Lucario was not his servant, but his partner and friend. Lucario sobbed a bit and smiled at that, understanding now Sir Aaron's sacrifice. He thanked Ash for showing him the same friendship Aaron provided. Lucario then disappears and, along with Aaron's crystallized form, two spirits floating up to the sky.
Kidd and Ash step outside to see that things are well. Kidd gets in touch with Banks, who tells Kidd that she will make a fortune from the information she has gathered, but Kidd decides not to publish this adventure, knowing the Tree would be ruined by tourists to which Banks reluctantly agrees. Ash reflected upon how valuable a friendship really is, especially between a Pokémon and a human.
Lucario with Ash before dying
Ash and company take a cable car down. Along the way they see Kidd packing up her Humvee and leaving. Later, they find out the tapestry in the castle showing Aaron holding up his scepter has changed; it now shows Lucario, Aaron's partner and friend, standing beside him. Bonsly remains with Mew at the Tree of Beginning, both of them thrilled to have found a friend. In what would appear to be the afterlife, Aaron and Lucario stand together when Aaron offers Lucario some chocolate before both of them walk into the distance. Ash and his friends meanwhile continue their journey through the Kanto region, ready to face any challenges that may await them.
