Kilmarnock228 is a big fan of the Kung Fu Panda franchise, having been involved in it since the first film. He enjoys Secrets of the Furious Five (for the most part), Kung Fu Panda 2, Secrets of the Masters, Kung Fu Panda 3, and Secrets of the Scroll; he also likes elements of Kung Fu Panda: Legends of Awesomeness but isn't a fan of some of the "humor" of that series. While the first season of Kung Fu Panda: The Paws of Destiny got a bit dark, in his opinion the end was quite impressive, and he's hoping it will continue to improve.
My Kung Fu Panda Sequel Idea
Did it ever strike anyone else as curious that Tai Lung and Tigress-both of them big cats who proved to have an aptitude for Kung fu-were both left on doorsteps in the Valley of Peace as infants? It gives me the impression that there might have been some kind of connection-perhaps some Dragon Warrior-esque prophecy regarding a cat warrior. However, this warrior is feared to become a force of great evil, and thus parents who have suspected that their child might be the one have left it in places where it was hoped they could learn to become good-natured beings. I think it'd be a cool way to get some focus on Tigress, and have Po helping her as the focus as opposed to him going on a journey of self-discovery for the fourth time.
So if you've seen Owl Be Back and The First Five, you know that supposedly there have been numerous generations of the Furious Five, with each group having its most powerful member become evil. I think it would be neat to tie this in to Kung Fu Panda 3 and say that Kai and Oogway were members of an early Furious Five, with Kai being the most powerful member. Oogway was able to briefly gain an advantage using the power of Chi or possibly the Wuxi Finger Hold, but as shown later Kai was able to defeat Oogway during their rematch 500 years later.
Additionally, I would venture to say that Kung Fu Panda: The Paws of Destiny characters Jindiao and the Four Constellations may also have been an earlier Furious Five, if not the first. However, as with Fenghuang many centuries later, Jindaio turned to evil, forcing his allies to unite against him. As a result, he is no longer remember among their number, hence the group's name of the Four Constellations rather than five. Furthermore, Po and the new Constellations could very well serve as the latest Furious Five, though the preceding group(s) remains active. I would also say that Bunnidharma strikes me as a possible member of Oogway's Five, and perhaps Zhizhu, though it'd be nice if there were some female members.
