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.
Yes, it is quite a popular concept. Many fans are drawn to the idea of Po and Tigress having a romantic relationship. Their different personalities - Po's jovial and food - loving nature contrasted with Tigress' strong and serious demeanor - create an interesting dynamic that writers like to explore in fanfiction.
One common theme is the 'opposites attract' concept. Po's carefree and fun - loving attitude towards life is very different from Tigress' strict and disciplined one. Another theme is the growth of their relationship. It might start from mutual respect as fellow kung fu fighters and develop into love over time.
One popular 'Kung Fu Panda Po and Tigress Romance Fanfiction' is 'A New Bond' on some fanfiction platforms. It explores their relationship in a really sweet way, showing how they gradually understand and care for each other more deeply during their adventures.
A different story could be about Po and Tigress swapping abilities for a day. Po suddenly has Tigress's grace and stealth, while Tigress has Po's unorthodox and powerful moves. They have to adjust to these new abilities while also dealing with a threat to the Valley of Peace. This would lead to some really funny and action - packed scenes as they try to figure out how to use their new skills effectively.
Po would likely become more responsible. He's always been a bit of a goofy panda, but with a baby on the way, he'd start taking things more seriously. For example, he might focus more on providing for his family and less on just having fun. Tigress, on the other hand, would soften. She's known for her tough exterior, but a baby would bring out her nurturing side.
The contrast between their characters. Po is this lovable, food - loving panda who is full of surprises, and Tigress is a fierce and strong warrior. Seeing them come together in a romantic way is exciting.
In fanfiction, they could be put in a situation where they have to rely solely on each other. Let's say they are trapped in an ancient temple filled with traps. Working together to escape would force them to communicate better and understand each other on a new level. This would not only strengthen their friendship but also show how they complement each other's skills.
It's a mixed bag. Some fans are content with the friendship that Po and Tigress have in the movies. They enjoy their platonic relationship as it adds depth to the story in terms of loyalty and mutual respect. However, other fans could be interested in seeing a love story develop. They might be attracted to the idea of how two such different characters could fall in love and how that would change their dynamic in the group. It could potentially bring a whole new level of complexity to the Kung Fu Panda universe.
