In a fanfiction where Tigress gets jealous, it could be that there's a new student at the Jade Palace. This student seems to get all of Shifu's attention. Tigress, who has always been Shifu's star pupil in a way, feels left out and jealous. So she starts to train even harder, but also gets snippy with the new student. Eventually, she realizes that her jealousy is unfounded when she sees that the new student just wants to learn and doesn't mean to steal Shifu's attention.
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 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.
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.
One idea could be that the OC is a new student at the Jade Palace. Tigress is initially skeptical but as they train together, they start to respect and eventually fall in love with each other. They face challenges together like a new threat to the Valley of Peace.
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.
Their married life would be full of adventure. They would continue to protect the Valley of Peace together. Po would bring his humor and love for food into their daily life, while Tigress would keep things in order with her discipline.
In the normal plot, the action is mainly centered around kung fu battles and the training of the Furious Five. But if Tigress is pregnant, the story could explore the relationships within the group in a new light. For example, how they support Tigress during her pregnancy. There could be less focus on combat training and more on things like preparing for the new arrival, like decorating a nursery or finding the right food for Tigress and the baby. It would also bring a softer side to the otherwise action - packed world of Kung Fu Panda.
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.
Another interesting plotline is if Baby Tigress has a vision of a great danger coming to the Valley of Peace. She tries to convince the other young trainees and the masters, but no one believes her at first because she's just a cub. So, she decides to take matters into her own paws and starts to train even harder to prepare for this impending doom. Along the way, she meets an old hermit who gives her some valuable advice and tools to face the danger.
