~History of Pokemon~
In the world as is known, it's covered with over 350 different types of Pokemon, all branching down to one origin: Mew. People have learned to bond with Pokemon and train them to develop their abilities further, these are called "trainers". One particular trainer, Ash, has traveled four regions and is now working towards winning the Battle Frontier. Along with his friends Brock, May, and Max, Ash has had many adventures, to which the next one he will have will be a far away place.

~A long time ago, in a land far away~
Fog decends over the land of Orudoran, as Lucario jumps from boulder to boulder to a spot overseeing a wide expansive valley. Nobody is there yet, but he senses something, as Ho-oh flies overhead. He closes his eyes, seeing the world's Aura Energy shaping the landscape. He's able to let his sight travel about, going over more rocks and hills until he sees a large formation of a gigantic Pokemon army mixed with human foot soldiers charging towards the middle of the valley, an army wearing green armor. He looks to the other side of the valley, doing the same, and seeing an equally gigantic army, with equally powerful, but different, Pokemon charging to the same destination, the army wearing red armor. After seeing these two, Lucario walks up to a crystal formation on the ground, touching it. He speaks through the crystal to Aaron who is at Orudoran Castle. Aaron stands upon a balcony with Lynn that overlooks the entire land, and he hears Lucario's voice coming from another crystal formation on the balcony. It seems there's little choice but to resort to one last action to bring peace to the two warring sides. Aaron hops a ride on his Pidgeot to the valley. At this rate, the war could endanger the sacred Tree of the World's Beginning.

While Lucario is waiting, three Houndoom from the red army find the unsuspecting Pokemon and attack him. Lucario evades them and runs off, the three canines following. After cornering Lucario, he's left no choice but to fight back. He dodges one lunging Houndoom, throwing an Aura Energy orb at it, easily taking it down. He handles the other two pursuers with ease.

But it also seems that Aaron isn't going to have an easy time getting to Lucario. Skarmory from green army go after Aaron and his Pidgeot. Fortunately for him, the steel birds only manage a few attacks before Aaron swoops down to find Lucario. Aaron tells Lucario that he must go to the Tree of the World's Beginning to save the planet from the ravages of war. Lucario, being loyal to Aaron, wants to come as well, but Aaron throws his scepter, turning Lucario into energy and drawing him into the jewel at the top. Lucario can see from the jewel Aaron going off, leaving Lucario there. Just as Aaron leaves, the two armies meet in the middle of the valley and begin their battle. Ho-oh returns to the Tree of the World's Beginning, revealing itself to be Mew.

From the balcony can see the tree suddenly start 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's happening. The light made them realize what they would do would ultimately prove disasterous, the two armies declare a truce, walking away to never battle each other again. But nobody knows what happened to Aaron, but the scepter that supposedly contains Lucario was found.

And with that, a mother reads on about the story to her daughter. A mere fairy tale it seems in a town that in the present next to the same exact Orudoran Castle.

~Title intro~ The scene shows what's inside the jewel of Aaron's scepter, as if looking through things in Lucario's eyes. Images of technological advancements showing that time swiftly passes by show. After displaying the "Gekijyouban Poketto Monsutaa Adobansu Jenaareshon" logo, the scene zooms out to show a galaxy before spinng around faster, turning into the "Mew to Hadou no Yuusha: Lucario" title.

Ash and company walk along a bridge to Orudoran Castle, they're dressed in their regular clothes while the others are in renaissance outfits. Meanwhile, a Taillow overhead lands on a window of the Castle, turning into a Pichu. In another room, Ash and company find a costume closet and decide to dress more appropriately. Ash wants a hero outfit and begins looking for one with the others find what they want. While they look for a costume, Pikachu notices a Pichu who hides behind the window curtains. It transforms into a Treecko and it walks out through the window before anyone can notice. May pops out first in a pink dress with a small pair of Beautifly wings on the back. She askes Pikachu what it thinks, Pikachu happily giving approval. Brock comes out wearing a clerical outfit while Max in a bard outfit. Ash lastly shows up in a hero's outfit, completely with a cape and a hat. They all look at Pikachu with sly grins, and soon dress it up in a cute jester-like clothes. They hurry onto the upcoming tournament that's about to happen. Just as they go out, Jessie, James, and Meowth find their way into the closet, and Jessie finds a outfit really fast.

Before the tournament begins, the queen of the castle, Eileen, along with her maid Jenny and her Pokemon Mime Jr, steps out to the royal box seat to officially begin the tournament. The first match is Ash against a trainer with a Breloom. He uses Pikachu. The battle ends rather quickly as Pikachu uses Thunderbolt, taking the chance while its opponent is stunned to tackle it, finishing it off with Iron Tail. During the tournament, the Treecko finds its way to the royal box seat and changes into a Mime Jr. Then at another point, Jenny sees the two Mime Jr, one of them turning into Aipom. Other battles pursue after that until things whittle away to the finals: Ash versus a trainer covered in a full knight armor. Ash uses Pikachu once more in the match, the trainer sends out a Weavile. At first the Weavile throws a Shadow Ball towards Pikachu, which it stops it by using Thunderbolt. Pikachu continues on to shocking Weavile until the whole battleground goes up in smoke, Pikachu being the victor.

At the end of the match, the Aipom goes off to Pikachu in the battlefield, celebrating its victory. Ash goes up to the trainer to thank for a great battle. The trainer takes off the helmet and to Ash's surprise, as well as May, the trainer is actually a girl! She introduces herself as Kid. May notices Brock and Max are missing, only to find them down there, where Brock tries to flirt with Kid, but Max pulls on his ear to drag him away. At the moment, Eileen announces that there will be a ball and banquent in honor of the "Aura Guardian".

Ash is presented to sit in a throne overlook the ballroom. Eileen presents Ash with Aaron's scepter, a sort of symbol of the Aura Guardian. As the scepter is being presented, Jessie and James sneak around in the crowd. Ash takes a look at the Jewel at the end, and sudden he hears a voice 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. May finds herself dancing with one of the guests, Freddy. In the corner, Brock nervously asks Kid to dance, she accepts to it, but Brock still finds his nervousness uncontrolable. Max is at the table where the food is, helping himself to some of the delicious food. Aipom and Pikachu also dance about in the corner. Seeing his Pikachu dancing, Ash decides to release his other Pokemon to enjoy themselves to the party, May also does the same.

With the new company, Aipom takes the Pokemon posse about through the castle. Meowth, who's helping himself to some food underneath the table, hears them and decides to follow them. Just as he gets close to a door the Pokemon group goes through, Grovyle slams it shut behind him, sending Meowth to a nearby fireplace pit. Aipom takes the Pokemon too the attic.

Up on the attic, Aipom shows the Pokemon around to a few toys and plays around with them. Squirtle and Corphish look at the upper level of the acttic to find a wooden train set. They stroll down to the first floor, taking Grovyle and Pikachu with them, going around until they hit a shelf full of bouncing rubber balls. The Pokemon find amusement with that as they bounce around on top and roll them about. After a bit, Aipom transforms into Pikachu and begins dancing with Ash's Pikachu.

Kid pauses from dancing with Brock, asking if he could get a drink. Brock goes off to get one immediately, and when he's gone, Kid slips away into the same direction the Pokemon 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. Getting a good grip, 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 looking a bit bored. For a while he looks at a huge tapestry of Aaron on the wall next to him, then he looks back down at the ballroom. Ash asks if he could get some food but Jenny keeps him down on the throne, telling him to act like a hero. Jessie and James are trying to blend in by dancing about, but soon they switch partners with May and Freddy. Jessie finds Freddy cute and dances widly (but still in the same fashion as everyone else) with him in excitement. James on the other hand is trying to keep his face away from looking at May directly. Max notices the Pokemon are missing, until Munchlax comes back to nab a plate of fruit and goes back upstairs with it. Max follows Munchlax to the top.

Kid manages to get to a good vantage point on the roof where she can see through the broken glass Meowth made. She see's Mew, putting on a pair of special glasses and begins reporting information. It's relayed from a humvee parked someways away from the Castle, all the way to a satelite orbiting space down to a tall building in the middle of a city. It seems that Kid is connected to a large organization and they seem to want some information about Mew and the Tree of the World's Beginning.

In the attic, the other Pikachu transforms into Mew, looking at Meowth to see if he's alright. Taking this chance, Kid sends out two Weavile, one carrying some sort of device. Both of them jump into the broken window and begin a swift attack at Mew. Mew dodges their assaults easily. In 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 device on Mew, Pikachu fries the cat with a Thunderbolt. Mew escapes to Pikachu, but the Weavile try another Blizzard attack. Both Mew and Pikachu dodge, the attack hitting the other Pokemon, freezing them. Mew then flies over towards Meowth who's at a corner, and transforms into a Meowth. Mew switches itself and Meowth around to confuse the Weavile, but they laugh, both soon throwing a Shadowball at them. Pikachu intervenes by throwing a Thunder at the two balls, ending up in an explosion.

Kid notices this and figures that the plan didn't go so well as expected. The explosion though knocked Pikachu out, leaving both Mew and Meowth 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. He sees Mew, not believing it at first. But soon Mew teleports before the Weavile can do anything else. The three teleport to one of the tower's steeples, Meowth slipping before Mew transforms into a Pidgeot and flies off, towards the Tree of the World's Beginning. Kid sighs at the slight setback.

Back at the ball, Brock walks to where Kid was with two drinks, but sees that she's not there. May is wondering why her dancing partner James isn't looking at her. But it seemed he was saved from blowing his cover when Eileen announced the next step in the ceromony. Jenny tells Ash to stand up and do the hero's pose. Ash's confused but Jenny points to the painting of Aaron, holding the scepter up above his head. Ash stands up and copies the pose. A certain point in the jewel allows Lucario to see, once again Ash hears a voice crying out "Why?". Again the voice speaks, and soon the jewel glows, releasing Lucario at the other end of the front of the ballroom. Lucario apparently is still seeing things in the form of Aura energy, mistaking Ash's form with Aaron's, who looks strikingly the same. Lucario walks up to Ash, kneeling down, that is until Ash spoke that he was the wrong guy. Lucario, surprised, opened up his eyes to see that it was not Aaron, but Ash he was standing in front of. Lucario becomes confused at what is going on, seeing the many people and a Aaron impersonator. But it was the same castle, and he had to make sure. Lucario soon escapes through the crowd of people, running around through the castle. He see's 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 it to be a bedroom. Ash, May, Brock, Eileen and Jenny confront Lucario in the room. Eileen says to Lucario that she is the decendant of Lynn, the queen who was reigning at the castle during his time. Lucario thinks about this for a moment, seeing the resemblance. Eileen walks up to Lucario and gives him a reassuring hug.

At the Tree of the World's Beginning, Mew looks after Pikachu, who's resting in a bed of leaves. Meowth seems to understand what Mew is up to, seeing a large pile of toys it's gathered.

They retire to the throne room for now. Ash wonders what other person Lucario could mistaken him for, Eileen explains to Ash and company the story of Aaron and Lucario. Possibly because Ash looks exactly like Aaron in Lucario's special vision. Lucario mentions also that Ash has a similar Aura pattern as Aaron had. Jessie and James overhear from a balcony above, Jessie wanting to capture Lucario. Just then, Max runs into the room, exclaiming he just saw Mew getting attack, and it took Pikachu and Meowth somewhere. Jessie and James also just realize Meowth is missing. Although at first everyone doesn't believe him, Kid 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 the World's Beginning. Ash asks what that is, so Eileen takes them out to the balcony overlooking the land. In the middle of the horizon stood a large tree. Eileen explains that the tree possess healing powers beyond imagination. With Mew, it could revive the earth and sooth angry hearts, although it requires Mew, the origin of Pokemon. Ash decides the only way to get Pikachu back is the go over there himself. Lucario also wants to go, not only does he know the area, he wants to know what happened to Aaron.

At that Kid comes out in her outfit, saying that she wants to go too. Brock knows exactly who Kid is now. He takes out his book of women he likes and then he shows them, Kid Samaazu. She's 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 was an honor (Mime Jr behind him mimics his actions). Kid says that she's here for the adventure, and she has a humvee that'll get them there in no time.

That night Lucario enters the unlit ball room, seeing the two huge tapestries of Aaron. One with him doing the hero's pose, the other with him riding upon his Pidgeot. He senses something and jumps back, hanging upon the wall above the open door for a second before he jumps down upon Ash who entered. Ash fights him off, wondering what's with him. Lucario just feels a bit edgy, upset with the fact that his master Aaron had left him without any reason why.

The next day, Kid takes Ash and company towards the Tree of the World's beginning, Lucario running up ahead. Eileen and Jenny stay behind at Orudoran Castle. Jessie and James hitch a ride in the trunk.

Pikachu wakes up from a falling leaf, seeing that it's with Mew and Meowth. Mew is excited that Pikachu is awake and well, playing around with it for a moment. Meowth tries to relax against a part of the tree, but falls into a hole concealed to be a branch stump. Pikachu goes up to where the hole seemed to be, Mew just simply pokes its head in. Pikachu pokes its head in as well, seeing a long vertical tunnel with green bubbles coming up. Mew hops onto a bubble, followed by Pikachu. They ride the bubbles for a bit, Mew bumping into Pikachu to make its bubble bounce all over the tunnel. Pikachu falls off but soon grasps on to another one. Both Mew and Pikachu bump into Meowth, making him bounce around. At another branch stump up higher, the three Pokemon come out. They walk up to the edge of the land, seeing the landscape below them.

The crew takes a break for lunch. Lucario finds some berries while he sits upon a boulder. The gang sit is about to eat lunch, Brock passing out the plates to everyone one by one. He gets three passed out but when he reaches for the fourth one (for Kid), a Bonsly takes it before he could get to it. Brock's confused for a second before he finds Bonsly below eating away at Kid's lunch. Brock scolds the Pokemon for eating Kid's lunch, but this only makes it cry. May and Max think Brock was too harsh, but 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 the World's Beginning, but they stop once more. This time, the road is littered with gysers that are erupting and for a while. 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 Pokemon, 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. It looks like the little guy took a ride with them, so May decides to take it along. She tries to take Bonsly into the water, but the small Pokemon jumps out and hides behind Phanpy, Max commenting because its a Rock type. Lucario sits upon a rock, remember the time when Aaron took him here. Aaron decided to wade after traveling about. He told Lucario to put his feet in the water since it feels good. Lucario was a bit reluctant but he did so, smiling at how relaxing it was. 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'll get it. Brock and Kid watch as Ash climbs up the small cliff. As soon as he grabs it though, he slips and falls off. May catches the plant, which looks like a crystalized pod, while Ash plunges into the water. Seeing how it's possibly a fruit, they decided to plant it. But just before they do, the pod suddenly blooms and the area becomes somewhat holographic as they see a replay of Ash falling off the cliff as he was getting the plant. Kid knows what it is, a Time Flower. She explains that it records events in time in the area it was planted and then it can replay the scene at a later time when activated.

Night falls as they travel, and they stop. They're rather close to the Tree, but it's best if they rest for now. Ash says that tomorrow he'll get Pikachu back. Lucario's a bit confused at why Ash would go this far to get Pikachu back. Perhaps if he's connected to Aaron somehow, he should just leave Pikachu like Aaron did to him. Ash gets angry at him suggesting that and he tackles Lucario down, 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 lege. He storms off thinking that people are just cruel. It appears that Lucario is very upset with Aaron. Ash felt that he might've gone too far seeing Lucario walk away. Lucario finds a tree to lean upon, recalling another memory.

Aaron was demonstrating the ability to see Aura Energies, the "Hadou", even while his eyes were covered. He dodged several logs as they swung back and forth towards him with ease. Lucario was learning this ability, and it would be his turn to do it. Lucario was nervous as he began dodging the logs, few missing by a hairpin, but he managed to pass the test. Just then, Max comes up and shows Lucario a bar of chocolate. He explains that it's a sweet snack and it's really good, breaking off a piece to give to Lucario. Lucario sniffs it and is a bit hesistant, but he sees Max eat and enjoy it. Lucario puts the bit into his mouth, enjoying it with a smile. However when Max catches that, Lucario tries to put on a stern face.

Later that night, Mew and Pikachu play about while Meowth sleeps. Mew finds a few toys, taking out a party blower in the shape of a Shuckle and blows into it a couple of times, dropping it near Pikachu. Then it goes back to find a Kapoera yo-yo and plays around with it. Pikachu smiles a bit, but it can't still help the feeling of being seperated 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, telling the time when he first got Pikachu, standing in front of the Spearow as they came down to protect Pikachu. Ash tells Lucario that he and Pikachu are friends, as Lucario tells Ash that Aaron is his master. Lucario doesn't quite understand the concept of being along side 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's going on. Lucario tells them this was the spot that Aaron sealed Lucario in his scepter. He remembers it quite well, but Lucario kicks a Time Flower gently by accident and soon it replays the scene it has recorded. It's the same exact scene, when Lucario meets up with Aaron, which he throws his scepter down and seals Lucario in the jewel. Then they watch Aaron fly off to the Tree of the World's Beginning. Suddenly from the two pathways on the road, the green army charges through the small pathway. Lucario appears horrified and begins throwing Aura Energy spheres at them, barely missing Ash. Ash tells Lucario to stop because they're only illusions. Lucario does stop, shocked to have seen that event happen. Ash comes up to Lucario, apologizing for being pushy when he hadn't realized how this affected Lucario. Lucario though gets up and smiles, perhaps Ash is right, that Aaron did that for his own good.

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 Regirock digs its way from the ground. It sounds mechanical, and begins using Hyper Beam upon the "intruders". Jessie and James manage to escape the humvee before it becomes a victim to Regirock's assault. Lucario intervenes at the second Hyper Beam it fires, throwing an Energy sphere at the beam, exploding in the middle. Using this, Kid finds a crevice to hide in. As they go, Lucario covers 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, it seems like they lost Regirock. At the end of the tunnel, they come to a large cave of ancient Pokemon. Amongst a vast lake and field, lit by a giant crystal on the ceiling, are Omanyte, Omastar, Yanma, Armaldo, Altaria, and Nidoran. It appears they made it into the tree, but now the only way to get to Pikachu is by going up. Ash goes on ahead to another tunnel, followed by Lucario. Kid takes out her specs, relaying info back to the company. Her boss tells here that the tree is designed with many tunnels that make a network like blood vessels. Energy can also be monitored. Kid deploys out small helicopter gadgets to gather information about the Tree, then she follows Ash.

The probes that Kid deployed attempted to take samples of the crystal that grew there. However, a red blob engulfs and eats them. Kid gets a warning that the probes were rapidly being destroyed, and that a sort of defense system in the Tree has been activated.

At the end of the next tunnel, Ash finds himself upon one of the "leafs" of the Tree. Ash runs up ahead once more, climbing up the leaf. He called out to Pikachu, who a few leaves up higher (which is a long way up), Pikachu hears Ash and calls back, Ash and Pikachu know that they're nearby. As things seemed to turn for the better, Regice stands in front of Ash's path and begins firing a barrage of Ice Beams. Lucario jumps into stun the Regi while Ash gets away. He gets to the tunnel, telling the others they must find another way because Regice is up ahead. Lucario throws one Aura Energy sphere at it to stun it long enough to get away. They find another tunnel along the 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. Jessie and James were the first two to run up, then the rest followed as Lucario covered their escape. Along the way, they ran into a narrow stone bridge, taking their time crossing it until the end. Jessie and James ran up way ahead. Lucario at the end of the line finds the Regi's hot on their tail. He sends a Aura Energy Sphere to the bridge, destroying before the Regi's have a chance to cross it.

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. The attack doesn't do a thing and Jessie is eventually swallowed up. Another comes after James, sending out Chimecho, but it's too late for his Pokemon to do anything. Ash and company arrive only to see the event, wondering what's going on with this place. One more, in the shape of a Aerodactyl comes after them, but Lucario destorys it with his Energy sphere. Soon the red blob figures come from behind. The other's try to find another way to get past them. One of them makes it through and almost catches Kid, that is until Lucario gets in the way. It takes Lucario, but soon explodes off. Apparently the thing doesn't eat Pokemon. Just when things also couldn't get any worse, the two Regis are once again behind their tails. As they run, they find a room with two tunnels. The group decides to split up so that at least one group will be safe from the Regi's, and they'll meet up later. Ash and Lucario go in one group and lure the Regi's away, while Brock, May, Max, and Kid make the other group. The four take off in one path while Lucario and Ash take the other. Ash stays behind though so that he can get the Regi's attention once they've come.

While the four travel through the Tree, the red blob strikes once more. This it takes Brock. But not wanting his Pokemon to go down with him, he releases them at the last moment. May and Max also gets caught, May releasing her Pokemon as well. Kid on the other hand is dodge two of them, managing to escape the blobs.

Lucario and Ash managed to lose the Regi's 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's a very strong wind. On the other side, Pikachu, Mew, and Meowth come out from aonther 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, flying for a bit before grabbing a hold of one of the pillars. His hat also flies away, but Mew manages to catch it. He continues on, going low when the wind gets too strong. Both him and Pikachu meet in the middle, where they jump to meet. But they jump a little too short and fall down. In the nick of time, Kid uses her grappling hook to swing across and grab Ash and Pikachu, heading to the tunnel where Lucario waits. Pikachu wonders who the new Pokemon is, Ash introduces Lucario to his friend and Pokemon, Pikachu. It seems Lucario is beginning to understand the more deeper relationship that could be possible. Mew joins in, along with Meowth, Mew giving Ash his hat back. Now to get out.

While going through the tunnels, they come up across the red blobs once more. They find a branch off to another tunnel and go through it in hope to lose them, but they 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 and stuns him, giving the red blobs a chance getting Kid and Ash. As both get "eaten", they release their Pokemon. Lucario kicks himself off Registeel to try and save them, but it's too late as Ash's Pokemon try a last hope approach to pull him away. But it's too late, he's gone as the blob slips into the ground. Ash's Pokemon saddened by their loss begin to cry. Lucario watches this, appearing hurt by the loss as well.

Mew though goes up, touching a crystal. It begins to glow green, as well as every crystal in the area. It appears as Mew is performing the healing spell the Tree is capable of. Soon the blobs, now green, form up into mounds and disolve away, leaving their victims behind alive and well just where they had taken them. As Ash is also released from the blob, his Pokemon celebrate with joy. The Regi's walk off, not seeing them as a threat anymore. Kid is happy that things are well too, that is until she notices that one of the crystals flash a red color and tells the others something isn't quite right. Suddenly all of the crystals become red in color, and Mew appears weakened. Kid picks Mew up, finding out that Mew is hot to the touch. Kid's boss says that the whole tree has gone unstable. If it gets completely destroyed, it could mean certain disaster for the world. The crystals also begin to blacken and crumble, the place is collasping, and fast! With no time to lose, Mew helps them 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 very weak to do anything. Lucario looks to the side and notices that there's a crystal formation, inside of it though is Aaron!

Lucario doesn't understand why Aaron is here, sealed up in the crystal, but his gloves are left on another formation 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 energy, the "Hadou", to Mew, the only energy that would suffice. Mew stores the power and once enough has been stored, goes to the core to begin the restoration. But at the end, the see Aaron tumble and fall in pain, looking quite different, and the scene ends. They now know what to do... but it would cost the person their life. Lucario, seeing how he can utilize the Aura Energy that Aaron can, declares he'd be the one to do it. Rucario goes up to Mew and begins transfering energy, but is soon pulled back. He realizes he's not strong enough yet to deliver the energy needed! Ash remembers that Lucario mentioned he had the same Aura pattern as Aaron, and can control Hadou as well. He puts on Aaron's gloves, which help channel the energy. Kid questions Ash's actions, but Ash says that saving the world is more importan than his life. Both Lucario and Ash begin channeling energy into Mew. It begins to work as Mew stores up the energy both are putting into it. As time passes and they channel more energy, it begins to strain them. But just at the end, Lucario shoves Ash out of the way. Lucario channeled the rest of the energy into Mew, protecting Ash from facing the certain death that would follow. 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 years ago. The crystals turn green and emit bright beams of light across the land, saving the Tree and ultimately the world.

After Mew completed the healing process, Kid confers with her boss if the Tree is stable, and everything is normal. But Lucario stumbles down, exhausted from what he's done, in the same condition as Aaron as he collasped. Lucario's hand bumped into a Time Flower, activating it. This time it was Aaron as he sat there, saying his last words. He thanked Lucario for being his servant and always being loyal. He did seal up Lucario, to protect his friend, not his servant, from the impending danger. He wasn't a servant to his master, he was a friend. Lucario smiled at that, understanding now. But his time was running out fast, and before it would run out, he thanked Ash for showing him the same friendship Aaron provided. Lucario soon dissapeared, along with Aaron's crystalized form, two spirits floating up to the sky. Kid and Ash step outside to see that things well, and reflect upon how valueable a friendship really is, especially between a Pokemon and a human.

~Ending Credits~
Ash and company take a cable car down. Along the way they see Kid packing up her humvee and leaving. Back in the cable care, Brock bawls over his "loss" of seeing Kid leave. The tapestry in the castle showing Aaron holding up his scepter changed, it now shows Lucario standing beside him. Kid explores Founce, right behind her is Batora and Dian tending to a farm. Ash and company take a visit to another city (which looks surprisingly like Alto Mare), above in their balloon is Jessie, James, and Meowth trying one of their attempts to get Pikachu, but end up in a mess as Meowth slips from the balloon.

Nearby Oradoru Castle, Aaron and Lucario walk down a road. Aaron however has some chocolate and shares it with Lucario.
