Well, a lot of times the storylines revolve around the human being a sort of outsider who disrupts Tigress's normal life. For example, the human might accidentally stumble into the Valley of Peace and Tigress is initially suspicious but then realizes the human has a pure heart. They then embark on a journey together, perhaps to fight a new threat that neither could face alone. There are also storylines where the human has a connection to an ancient prophecy that involves Tigress, and they must figure out how to fulfill it together, with lots of character growth and adventure along the way.
Common storylines often include a human who is a great warrior in their own right in the human world but is out of place in the Kung Fu Panda world. Tigress at first doubts the human's abilities but as they train together, she comes to respect them. Another is a story where the human is a healer or a scholar and they help Tigress and the other characters deal with a new disease or a problem that requires knowledge rather than just brute force. And then there are the more romantic storylines where the human and Tigress slowly fall in love despite the differences between their species.
It's not that popular. See, the Kung Fu Panda franchise mainly focuses on the relationships between the animal characters. So a fanfiction involving a human and Tigress is a bit of a stretch. Most fans are more interested in the existing relationships within the movie, like the relationship between Po and his friends or the different animal clans. But there are still a few fans out there who might be into this kind of cross - species fanfiction for the novelty factor.
A common theme is self - discovery. Since Tigress is a complex character, many fanfictions explore her journey to understand herself better, like her emotions and her place in the world of kung fu.
One idea could be a human discovers the world of Kung Fu Panda and befriends Tigress. They go on a journey to find a long - lost Kung Fu technique. Along the way, they face various challenges that test their friendship and skills.
Friendship is a very common theme. Their friendship that started as comrades in the kung fu world often gets explored further. Writers might show how they support each other during tough times.
In the Kung Fu Panda series, their story is mainly centered around their growth in kung fu and their friendship within the Furious Five. Po is often clumsy but has a big heart, and Tigress is the strong and serious one. They support each other in battles and in training, but not in a romantic way.
One possible fanfiction could be about Baby Tigress' training days. Maybe she was the smallest among the young animals training in the Jade Palace but had the fiercest determination. She could be shown struggling with some of the basic moves at first, like how to properly execute a paw swipe. But with time and the guidance of Master Shifu, she gradually overcomes her difficulties and starts to shine among her peers.
There could be a fanfiction where Po and Tigress go on a special adventure together. Maybe they discover a new martial arts technique that combines Po's unique style with Tigress's strength and precision. They might face a new enemy that challenges their relationship and forces them to work even closer.
Perhaps Po and Tigress get into an argument about the best way to train the new students at the Jade Palace. Po wants to use his fun and unorthodox methods while Tigress believes in strict discipline. Through this argument, they learn to respect each other's views more and find a middle ground.
A fanfiction plot could be centered around a human who accidentally stumbles into the Kung Fu Panda universe. Tigress mistakes the human for a threat. The human tries to explain but in the chaos, a fight breaks out. The human, though not as strong as Tigress, is very resourceful. Tigress is impressed by the human's tenacity and they form an unlikely alliance to face a greater threat in the Kung Fu Panda world.
One common theme is the overcoming of differences. Po is a panda and Tigress is a tiger, and their different natures and backgrounds can be explored as they fall in love. Another could be the growth of their relationship from just being comrades in kung fu to something more romantic.
