Pokémon 4Ever, also known as either Celebi: Voice of the Forest in the English version or Celebi: A Timeless Encounter in Japan, is the fourth Pokémon film.A long time ago, a little forest guardian known as Celebi is chased by an unknown Pokémon poacher. A young Trainer, Sam, saves Celebi, and the two travel through time. In the present day, a member of Team Rocket, known as the Iron Mask Marauder ("Vicious" in Japanese), confronts the now-old poacher and destroys his home, taking a Tyranitar with him.Ash, Misty, and Brock see a Suicune, and Oak tells them about the legendary Pokémon. While in the woods, they see Sam, and they befriend him. Unfortunately, the Iron Masked Marauder plans to capture Celebi for himself, and he plans to overthrow Giovanni in the process.
The movie provides examples of:
All Just a Dream: In the Japanese version, Sam wakes up after being returned to the past and mentions he had "a wonderful dream." In the dub, this isn't the case.
Adaptation Expansion: Or in this case a dub expansion. 4Kids had the Japanese animators create additional scenes to make it more clear that Sammy is Professor Oak.
In all honesty, the fact that the movie leaves a few hints scattered throughout and that the second movie revealed the full name of Professor Samuel Oak was enough for most Japanese fans.
Adapted Out: Tracy makes two appearances as Oak's assistant. Both scenes were removed in the dub version.
Eldritch Abomination: Whatever the hell Celebi makes out of the chunks of forest it decimates. It has spider legs, horns, skeletal wings, and can blast the crap out of about half a mile of tree canopy to vaporize half of the lake on the other side.
I Never Told You His Name: In the final scene, the gang tells Professor Oak about their most recent adventure and Professor Oak notices Ash is unusually subdued. Ash tells him about the boy he befriended who went back to his own time and how Ash is worried they'll never meet again. Professor Oak reassures him that true friendships stand the test of time and that "I'm sure you and Sammy will be friends forever." After the video call is over, Misty realizes they never mentioned Sammy's name to the Professor... Cut to Professor Oak in his lab looking through his old sketchbook and saying, "It seems like it happened only yesterday."
Saying Too Much: In one of the 4Kids-added scenes, Misty realizes how strange it was for Professor Oak to know Sam's name, even though Ash never mentioned it.
Schizo Tech: The past that Sam comes from is pretty inconsistent in tech level. On one hand, Poké Balls from that time period need to be wound-up before use. On the other hand, a poacher from that period has a cyber eye and electro-trap, while riding a fairly old motorcycle.
Shout-Out: There's a trainer who's named Dundee in the English dub. He's got a Croconaw. He's also got an Australian accent.
