Pokemon movies usually follow a pretty safe recipe. Ash finds a legendary, Team Rocket tries to steal it, there’s a big fight, and everyone goes home happy. But then you have Lucario and the Mystery of Mew. Honestly, if you grew up in the mid-2000s, this movie hit different. It wasn’t just a 100-minute commercial for the next generation of games. It was a genuine tragedy.
It’s heavy.
Even today, looking back at the eighth film in the franchise, it stands out for being remarkably bleak compared to the fluff that came before and after it. We’re talking about a story that starts with a betrayal and ends with a main character literally dying. Not "Pokemon Center" fainting—actually passing away.
Why Lucario and the Mystery of Mew Still Matters
Most people think this movie was just a vehicle to introduce Lucario before Diamond and Pearl launched. They’re partly right. But the actual meat of the story is about the trauma of being left behind. Lucario is trapped in a staff by his master, Sir Aaron, right as a massive war is about to destroy their kingdom. He spends hundreds of years in total darkness, convinced his best friend abandoned him.
That’s a lot for a kid’s movie.

When Ash accidentally releases him at the Cameran Palace festival, Lucario doesn't want to go on an adventure. He's bitter. He’s cynical. He basically tells Ash that humans can't be trusted. It’s a level of interpersonal friction we rarely saw in the anime back then. You’ve got Ash, the eternal optimist, clashing with a Pokemon that has legitimate PTSD.
The Real Story of the Tree of Beginning
The setting is another reason this movie stays in your head. The Tree of Beginning isn’t even a tree. It’s a giant rock formation that acts as a living organism, complete with an "immune system" made of Regirock, Regice, and Registeel. These aren't the friendly Pokemon you see in the wild. They’re ancient golems designed to hunt down intruders.
The movie gets weirdly sci-fi here. The "antibodies" of the tree start absorbing people. Remember that scene where Ash and the others are literally consumed by the tree? It’s terrifying.
Then there’s Mew.

This isn't the playful, god-like Mew from the first movie. This Mew is isolated and almost parasitic in its relationship with the Tree. The movie implies that if one dies, the other goes with it. When the Tree’s defense system goes into overdrive, it starts dying, and so does Mew.
The Mystery of the Aura Guardians
The film introduced the concept of Aura, which basically became the Pokemon equivalent of the Force. It wasn't just a gimmick. It suggested that some humans, like Sir Aaron and eventually Ash, have the same spiritual energy as Pokemon.
- Sir Aaron’s Sacrifice: For years, the legend said Aaron was a hero who saved the kingdom. Lucario thought he was a coward. The "Time Flower" visions eventually reveal the truth: Aaron gave his life to feed the Tree enough energy to stop the war.
- Ash's Connection: This is the movie that officially confirmed Ash Ketchum has special powers. His Aura is a perfect match for Aaron’s.
- The Final Choice: At the end, to save Mew and the Tree, Lucario and Ash have to use their Aura. But humans can't handle that level of energy output. Lucario pushes Ash away at the last second, taking the full brunt of the energy drain himself.
Lucario dies. He fades away while seeing a vision of Sir Aaron waiting for him in the afterlife. They even show them together in the credits, eating a bar of chocolate. It’s a punch to the gut every single time.
What Most People Get Wrong About Mew
There is a common misconception that the Mew in this movie is the same one that fought Mewtwo in the first film. It probably isn't. Aside from having a different voice actor (Satomi Korogi vs. Kouichi Yamadera), its behavior is totally different.

The Lucario and the Mystery of Mew movie portrays Mew as a lonely creature that "kidnaps" toys and Pokemon just to have company. It’s a much more vulnerable, almost tragic version of the character. It doesn't live in the jungle; it lives in a rock that eats people. Context is everything.
Practical Takeaways for Fans
If you're revisiting the movie or watching it for the first time, keep an eye on the details. The production team actually traveled to Neuschwanstein Castle in Germany to get the architecture for Cameran Palace right. It gives the movie a European fairy-tale vibe that’s unique in the series.
Also, look for the "Time Flowers." They’re more than just plot devices; they show how the Pokemon world viewed history before Pokedexes and Poke Balls existed. The movie is set in a time when "monsters" were still seen as terrifying forces of nature, not just pets in pockets.
How to Watch It Now
Finding this movie isn't as easy as it used to be. It was the last film dubbed by 4Kids Entertainment before the voice cast changed for the Battle Frontier season.
- Check digital retailers like Amazon or Google Play.
- Look for the "10th Anniversary" DVD sets if you want the original 4Kids dub.
- Pay attention to the aspect ratio; the US DVD release was unfortunately cropped to full-screen, while the Australian and Japanese versions are in widescreen.
Ultimately, this movie is about the fact that heroes aren't always what they seem. Sometimes they leave you behind to save you. It’s a hard lesson, but it’s why Lucario became one of the most popular Pokemon in history.
To get the most out of the lore, you should compare the "Aura" scenes here with the Pokemon Journeys episodes where Ash finally trains his own Lucario. The show didn't forget this movie, and neither should you. Focus on the subtext of the relationship between Ash and Lucario; it’s the blueprint for everything that came later in the Sinnoh era.
