Power Rangers Jungle Fury is the 2008 season of Power Rangers, which tells the story of the fight between the Jungle Fury Power Rangers and the forces of evil led by the spirit Dai Shi.

The Pai Zhua (Chinese: 派爪, Pài Zhuǎ) (also known as the Order of the Claw) is the leading protagonist faction of the series. Each member of this faction is given an Animal Spirit that acts as their own unique sentient, beast-like power source. They commit their lives to fusing the idea of martial arts with the abilities of these distinct Animal Spirits. They are the guardians of Earth against the abusive use of Animal Spirits by the series' antagonists, the Dai Shi Clan led by and named after the heartless spirit Dai Shi, for the extinction of humanity and the replacement by and ruling of evil beasts. The Pai Zhua fight against evil by calling on the spiritual powers of beasts and combining such a power source with the martial arts of humanity to use a human and beast spirit dual offense collaboration as a safeguard against the Dai Shi Clan's ways, using this combination of two forms of aggression for good causes.

The Pai Zhua's forces are divided into small groups who each exist with different means, methods and other skills but otherwise all live for the same righteous purpose: the defense of Earth against Dai Shi and both his schemes and forces:

The Power Rangers in this series combine the partnership of humanity's martial arts and Animal Spirits together with special technologies that serve to provide an essential enhancement to their ways of facing evil forces - such a combination of the Pai Zhua's styles of living and the mechanics of these technologies gives benefits that, as the series progresses, also demonstrate valuable lessons that the younger members of the Pai Zhua learn and understand and thus eventually embrace for the rest of their lives.

The assembly of all of the Rangers in this series takes place divided as separate stories that arise as the series runs its course.

Theo and Lily, the Blue and Yellow Rangers, are introduced as two of the Pai Zhua's six 'finalist' senior students who each must fight a fellow finalist student they are paired with as part of a special event of three simultaneous finalist battles that will decide three winners who shall be assigned the duty of safeguarding the chest-sealed spirit of the evil Dai Shi from escaping and starting his ways once again - they must use all of the lessons, training and discipline they have gained so far try to defeat the finalist senior students they are assigned with for their battles. Eventually Theo and Lily win, and become two of the three who will ensure Dai Shi stays sealed.

Casey, the Red Ranger, is introduced as being a part of a group of assistants for the Pai Zhua's students before his life in the Pai Zhua is redefined prior to becoming a Ranger.

Jarrod, one of the senior student finals winners, is a winner just for a few minutes due to the events which happen after the final. Jarrod instructs an assistant with an unfair, abusive, self-centered, and dissatisfied attitude to perform a request. Casey, who sees this happen, rushes to fulfil Jarrod's request in the abused assistant's place. Jarrod pushes Casey back in an aggressive, unsatisfied response, and Casey unleashes a tiger's roar in retaliation. The students' teacher, Master Mao, witnesses these events and comes to the decision to relieve Jarrod of his status as one of the three guardians of Dai Shi's chest. Casey becomes the third and final member of Dai Shi's chest's safe-guardians by Master Mao's choice.^{[citation needed]}
