In Secrets of the Furious Five
Viper was born as the beloved daughter ofGreat Master Viper, protector of the village where she lived who relied on his venomous fangs to defeat his enemies, and his beautiful wife. The Great Master hoped that she would carry on his legacy once she was born, but she was born without fangs and never developed them as she grew up, much to the dismay of her father. To make her father feel better, Viper took up ribbon dancing at the age of nine, blossoming into the best dancer in the village.
During the Moon Festival, Viper was too timid to attend the festival and instead stayed home with her mother. But when her father fought against a gorilla bandit who attacked the village and used venom-proof armor to shatter the Great Master's poison fangs, Viper, seeing him in trouble, mustered the courage she needed to defeat the gorilla by confusing him with her dancing skills and tying him up with her ribbon. Thus, her father's legacy was secure with his daughter becoming a mighty warrior on her own terms.
Some time later, Viper put her fighting skills to use when she came to learnKung Fu under Shifu, eventually achieving the rank of Master and forming theFurious Five together with Tigress, Monkey, Mantis, and Crane.In Kung Fu Panda
Viper was first seen training with Master Shifu with the rest of the Furious Five, where Shifu told her to improve on her "subtlety". Their training was cut short, however, when Master Oogway had a troubling vision: Tai Lung will break free from prison and return to the Valley of Peace. In response to this, the Dragon Warrior Tournament was instigated, in which each member of the Five participated in performing their skills to their Masters and the entire Valley. During the tournament, Oogway suddenly sensed the presence of the Dragon Warrior. Viper and her comrades quickly gathered in a line for the choosing. As Oogway approached, it appeared as though his finger was moving towards Tigress's direction, but then a portly panda named Po unexpectedly fell out of the sky right in front of Tigress. Taking this as a sign from the universe, Oogway declared Po the Dragon Warrior, stunning Viper, the Five, Shifu, the villagers, and even Po himself.
After the tournament, the Five all headed over to the Training Hall to train, with Viper honing her flexibility and reflexes in the Field of Fiery Death. She and the others stopped training momentarily to watch Po spar with the Adversary. The sparring ended with Po being knocked into the training course, and his following ordeal ended in him being burned in the same course Viper was training in minutes earlier. That night, while traveling up to the student barracks, the Five mocked Po over his lack of ability to do Kung Fu. Though Viper laughed with the others, she did not actually mock the panda, instead worrying how "the poor guy is just going to get himself killed." Neither she nor the others noticed Po listening in on them.
The next morning, it appeared as though Po had quit, but when Shifu and the Five enter the training courtyard, they were surprised to find that not only had Po not quit, he arrived there first. Po's training began, with Viper being the first to spar with him. She asked if he was ready, and Po barely had time to confirm before she flung him into the air and slammed him down again. When Shifu sparred with Po himself, Viper watched nervously as he flung the panda around and eventually kicked him out of the Palace and down the steps. Noticing Po's tenacity and gaining some respect for him, Viper silenced Mantis with a hiss when he commented on Po's "bouncing" down the stairs.
Once Po made his way back to the Palace, Viper and Mantis attempted to help him recover through means of acupuncture. However, Po's bulk made finding the right nerve points difficult, thus Mantis caused Po even more pain each time he stuck a needle in his back. The three eventually started up a conversation, commenting on Shifu's harsh way of treating Po. Eventually Tigress joined their conversation and told the story of Tai Lung while Mantis continued to apply more needles to Po's back. At the very end, he accidentally slipped up one needle and triggered Po's facial nerve, temporarily paralyzing him and stopping his heart.
Later that night, Viper and the others all have dinner together in the barracks kitchen. Po served his noodle soup to the Five (excluding Tigress), and Viper complimented that it was amazing. She also laughed along with the others (again, excluding Tigress) when Po did an impression of Master Shifu. But when the master eventually showed up in the middle of Po's impression, Viper immediately stopped laughing. He was shocked with all the others upon hearing Shifu's announcement of Oogway's passing and Tai Lung's breakout, and stuck by Tigress' side when she insisted they handled Tai Lung themselves. Later that night, after Shifu outlawed their request, Viper and the others followed Tigress out of the Palace that night and explained that they were joining Tigress and together to find and stop Tai Lung.
After days of traveling, Viper and the others finally located Tai Lung on the Thread of Hope just outside the Valley. A long battle ensues, each of the Five using incredible skill and prowess to fight the snow leopard. Viper assisted by using her incredible skills to fight Tai Lung after Tigress falls off the bridge but Crane saves her. Then Viper gets attacked and calls out to Monkey to save her then they all attack together sending Tai Lung to his doom. But when it seemed like they had won, Tai Lung reappears again and performs a chi block on four of the Five (Viper included) — only sparing Crane so he was able to carry the rest of them back to the Palace in means of a message.
Shifu and Po had just finished another day's worth of extensive training when they finally returned, Crane exhausted and the others paralyzed. The Five each told about their grieving experience, which placed doubt into Po when he realized that not even his idols, let alone five Kung Fu Masters, could stop Tai Lung. But Shifu still believed he could defeat him, and they all went to the Hall of Warriors in the Jade Palace to retrieve the Dragon Scroll for Po. Shifu, Viper, and the other Five watched as Po opened the scroll, and appeared just as confused when he said it was blank. Believing nothing else could be done, Shifu offered to stay behind to hold back Tai Lung while they and the rest of the Valley escape. Master and students shared a final respectful bow, knowing that Tai Lung may very well kill him.
While Po went to find his father, Viper and the other Five assisted in evacuating the Valley. Viper was tasked with gathering the southern farmers, to which she did so before moving out with the others. They were all just about out of the Valley when a large golden gust pulsed and blew past them. The Five and the other villagers returned to investigate and found Po victorious in his battle with Tai Lung. Marveling at the panda's skill that enabled him to do what they could not, Tigress led Viper and the others of the Five (as well as the villagers) in a respectful bow to Po as a Kung Fu Master.
In Kung Fu Panda Holiday
After defeating several boar bandits, Viper (along with the rest of the Furious Five) were shocked to find out that Po was going to be hosting the formalWinter Feast dinner at the Jade Palace. The Five offered to help, but Po insisted he could do it himself. When he was later overwhelmed by the myriad of responsibilities, he finally decided to call upon the Five to assist him with the preparations. Viper performed her "Stars Of Destiny" move to hold up the table lanterns that Tigress threw with her "Tahlia Leap".
When all the tasks had been completed, Viper later sat at the table with all the other Kung Fu Masters for the Palace Winter Feast. However, the formal dinner was soon interrupted by Po himself, who explained to the Masters the need to comply to his own family traditions, and thus excused himself to be at home with his father for the holiday. After Po left, Viper mentioned how she loved cooking with her sisters when she was younger. Viper and the rest of the Five understood Po's decision, and they all decided to join Po at the Noodle Shop. Later, Viper partook in a group portrait of the Furious Five, Po, Mr. Ping, Shifu, and Wo Hop.
