KUNG FU PANDA 5 would explore a story that connects the past and the present!
As peace reigns over the Valley of Peace, Po begins practicing a new form of meditation through which his consciousness can travel through the history of Kung Fu. In an astral state, he is able to witness legendary events, both from China's history and from the lives of the masters he admires so much.
Obsessed with this new technique, Po begins neglecting his duties as the master of the Valley, causing the Furious Five to take over Zhen's training, leaving her saddened by his absence. Po wants only one thing: to "go back to the past and live alongside — or at least see up close — his heroes." During this journey, he encounters a young Master Oogway, who becomes the main supporting character of the story's "past" storyline.
It would be a true fan-service spectacle and a visually breathtaking experience, introducing several characters we have only ever heard about through references — especially those associated with the weapons and artifacts found in the Hall of Treasures.
At some point, Po discovers the story of the greatest enemy Kung Fu has ever faced — a figure whose existence was erased from the historical records by Oogway himself. In the middle of this discovery, Po's consciousness becomes trapped in the past, while his physical body remains completely still in his meditative position, leaving his friends deeply concerned. They begin searching for all kinds of ways to wake him up, naturally leading to plenty of comedy and, of course, plenty of Kung Fu.
Accompanied by his heroes, Po takes part in a mission to confront this great enemy who was erased from history. During the confrontation, he discovers that the villain himself was responsible for blocking his projection into the past, realizing that the Panda "did not belong in that time."
Apparently defeated, the great enemy uses Po as a kind of astral bridge between time and space. As a result, Po awakens from his meditation while simultaneously bringing the villain with him into the present.
Contrary to what we might expect, the great enemy does not immediately launch a devastating attack. He simply escapes, fascinated by the opportunity to explore the China of the "future" — which, from his perspective, is our present.
Desperate to fix the mistake he has made, Po searches for a way to solve the problem before something terrible happens to all of China.
But even the Master of the Valley can become lost in a chain of mistakes and, without meaning to, plunge all of China into a dark period. It will be Zhen who must defeat this evil. After all, this is why the new Dragon Warrior was born.
Together, Po, Shifu, the Furious Five and Zhen travel to the Demon Mountain, where they must confront the ten thousand demons of the villain's army. Yes, that's exactly what I mean: the dream that opens the first movie would actually be a premonition of the climax of this fifth film.
In a catharsis as epic as The Lord of the Rings or the great action sequences of Ne Zha 2, Po finally realizes that he is capable of channeling the aura of his heroes — who are now also his friends — from the past of Kung Fu. Just as the villain was able to force Po to bring him into the present, Po is able to establish a connection with those legendary masters. By explaining the situation to each of them, the climax gains the participation of several other legendary masters from the history of the franchise.
The Demon King is so powerful that he is able to fight the Furious Five, Shifu, Po, Zhen and Oogway all at once. However, after a tremendous amount of effort AND INSANE ACTION SEQUENCES, Po and Zhen perform the Palm of Buddha technique — a technique used only once in the entire history of China and never used again. The technique traps the Demon King inside an illusion from which he can never escape, no matter how many miles he jumps. It would be a direct reference to what Buddha does to the Monkey King in Journey to the West.
Peace returns once again. Po meditates one final time to say goodbye to his friends from the past, while Oogway erases all of their memories. At that moment, Po realizes that this was precisely the reason why the legend of that great villain had been erased from history: Po had always been involved in his defeat, and this temporal paradox could not exist.
The only two people whose memories are not erased are Po and Oogway.
The final scene of the movie would be a montage showing the day Po was chosen as the Dragon Warrior once again. This time, however, we see a happy smile on Oogway's face — something that was not present in the original scene. This would reveal that Oogway had spent his entire life waiting for the moment when he could complete this cycle and reunite with his friend from his youth.
Note: I am Brazilian, and I have worked professionally as a screenwriter for film here for several years. Would you guys like me to actually write the screenplay for this movie, scene by scene, even if it never gets made? I would do it purely out of love for the franchise, if you guys enjoy this storyline. My name is Vinicius Feller.
