A great plot twist might be that Po discovers he has some hidden connection to Tai Lung. For example, they could be related in some long - lost family way. This would add a whole new layer to their relationship and the story. Po would then have to grapple with the idea of fighting someone who is, in a way, family, and Tai Lung could use this knowledge to his advantage in different ways during their confrontations.
Perhaps a plot twist could be that there is a third force at work. An ancient evil that has been manipulating Tai Lung all along. When Po and Tai Lung are in the middle of their big fight, this new threat is revealed. They then have to decide whether to continue their feud or team up to face this greater danger. This would force them to put aside their differences and work together in an unexpected alliance.
A plot could be centered around Tai Lung's past. Po discovers some hidden secrets about Tai Lung's training and upbringing. He decides to go on a journey to find out more. Along the way, he meets characters who knew Tai Lung when he was young. This leads to a better understanding of Tai Lung's fall from grace and also helps Po in his own growth as a warrior. For example, Po might find an old master who trained Tai Lung briefly and learn from their experiences.
In a fanfic, Tai Lung could be redeemed. Maybe he was wrongly influenced in the past. Po, being the kind - hearted panda, decides to help Tai Lung find his true self. They start training together, and Tai Lung begins to see the value in the Dragon Warrior's way of life. Their relationship evolves from enemies to something more like mentor - mentee in a reversed way, with Po guiding Tai Lung.
One possible plot could be that Tai Lung somehow returns, not fully evil this time. Tigress, initially suspicious, gradually discovers that Tai Lung has had a change of heart after his time in prison. They could team up to face a new, greater threat to the Valley of Peace. Maybe a dark sorcerer has emerged and their combined skills are needed to defeat it.
They could form an alliance if they found a common enemy. For example, if a new, more powerful villain emerged that threatened the Valley of Peace. Tai Lung might see that working with Po is the only way to protect what he once tried to destroy.
Well, if Tai Lung was injured and Po found him instead of fighting him right away. Po could take Tai Lung to the Jade Palace and nurse him back to health. During this time, they would have conversations and Tai Lung would see the kindness in Po and the true meaning of the kung fu that he once coveted. This would change their relationship from one of enmity to one of mutual respect and a strange kind of friendship.
If Tai Lung was redeemed, it could completely change the dynamic in the Kung Fu Panda universe. He was such a powerful and once - malevolent force. Maybe he would use his skills to train the next generation of warriors alongside Po. He could bring a different perspective to the teachings of kung fu, one that was born out of his own struggle and redemption.
One plot twist could be that the kiss is actually part of a dream. Po dreams of kissing Tigress, but when he wakes up, he's confused about his feelings. This would create an internal struggle for him as he tries to figure out if his dream feelings are real. Another twist could be that the kiss is seen by Shifu, who then has to decide how to handle this new development between two of his students. He might worry about how it will affect their training and the harmony in the Jade Palace.
One possible plot could be that Po and Viper go on a special mission together outside the Valley of Peace. They encounter a new villain who has a unique fighting style that combines elements of ice and wind. Po's clumsy yet powerful moves and Viper's swift and flexible attacks would make for an interesting dynamic as they try to figure out how to defeat this new threat.
It depends on the context. If we're talking about physical strength in a direct fight, Tai Lung was extremely powerful with his leopard style. But Tigress is no slouch either. In terms of personality, Tigress is very determined and disciplined, which could make her more dominant in decision - making situations. However, Tai Lung, if he were to return with a new perspective, could also be very persuasive.
It might not be a widely popular concept in the general Kung Fu Panda fandom. The relationship between Tigress and Tai Lung in the original movie is more of an antagonist - protagonist dynamic. However, in the world of fanfiction, some niche groups might explore this idea for the sake of creativity and exploring different character relationships.
