Synopsis
With the next clue from Navi saying that they need to find the tiger child, the Gokaigers face off against Space Kenpō Master Pachacamac XIII. When he takes away their weapons, Doc and Ahim find their hand-to-hand skills are lacking and start training under Jan Kandou, the former GekiRed.

Plot
With the next clue from Navi saying that they need to find the tiger child, the Gokaigers search to no avail before their search is interrupted by Cosmic Kenpō Master Pachacamac XIII. Furious of the interference, the Gokaigers fight Pachacamac yet Ahim and Don are outmatched by Pachacamac's Cosmic Kenpō fighting style with the others assume the forms of the GaoRed, GaoYellow, and GaoBlue to drive him off. Later, talking over their level of skill in fight, Ahim and Don come across Geki Jū Tiger-Ken master Jan Kandou with the former wanting to train along with the children that Jyan's teaching while Don chickens out. That night, after Navi explains to the crew that they jump to the wrong conclusion by going after a tabby and later realize that they trained themselves, Don resolves to get strong as Captain Marvelous and Luka. The next day, Don joins Jan's class to Ahim's surprise while the rest of the GokaiGalleon crew battles Pachacamac using the power of the Sun Vulcan team. However, Pachacamac uses a new technique thanks to Insarn's modifications. When contacted by Navi about their crewmen in trouble, Ahim and Don learn from Jan that their training is over as he reveals himself as the tiger child they are looking for. Arriving at the battle, GokaiGreen and GokaiPink tell the others to use the Gekiranger Keys to counter Pachacamac, weakening him before using the Gokai Blast Final Wave to finish him off. When Pachacamac enlarges, GokaiOh is formed to fight him using the Gekiranger Keys to summon Qi-based images of the GekiBeasts to destroy the villain. Elsewhere, as Don is now able to stand up for himself, Jan tells Master Xia Fu that he will entrust the future of the planet to the Gokaigers.

Gokai Changes

 * Gokai Changes in Niki-Niki! Kenpō Lesson:
 * Gokai Red - GaoRed, VulEagle, GekiRed
 * Gokai Blue - GaoBlue, VulShark, GekiBlue
 * Gokai Yellow - GaoYellow, VulPanther, GekiYellow
 * Gokai Green - GekiViolet
 * Gokai Pink - GekiChopper
 * All of the Gokai Changes in this episode involve felines:
 * Sun Vulcan: First team with a feline (VulPanther).
 * Gaoranger: First team lead by an actual feline (Gingaman was lead by an alien creature who resembles a lion).
 * Gekiranger: Main trio/Triangle are all felines (Tiger/Cheetah/Jaguar).
 * In the first set of Gokai Changes in the episode, both teams involve elements of air, water and land, but Marvlous and Luka switch places with both teams. Joe remains the aquatic creature in both changes, which coincidentally are both Sentai teams that utilize sharks.

Elements/Homages to Gekiranger

 * The title of this episode is similar to one of Gekiranger: it begins with an onomotopeia-like word that is made of a two-syllable word repeated twice, which is a typical trait of Jan. This title is reminiscent of the first Gekiranger title from the onomotopeia, with the original as Niki-Niki! Fierce Beast-Fist!
 * Pachacamac XIII is the descendant of the main villain of the Juken Sentai Gekiranger vs. Boukenger crossover movie.
 * The Air/Water/Land change by Marvelous, Joe and Luka is representative of the air/water/land concepts utilized in the first half of the series, both in the three training masters of the Gekiranger (Bat, Shark, Elephant) and in the three Fist Demons who are the main villains of the first half (Hawk, Jellyfish, Bear).
 * Jan is still wearing the orb that contains Long around his neck.
 * The splitting of the Gokaiger into two groups for most of the episode has multiple significance connected to Gekiranger:
 * Having Marvelous, Joe and Luka on their own emphasizes the concept of the "Triangle", the main trio which is the core of the main Geki Juken team; while the joining of Don and Ahim by the end show the addition of the two team-members (GekiViolet and GekiChopper) in the second half to support the Triangle.
 * The splitting of the teams into two show the style of two parallel teams having stories that intersect, thus the stories of the Gekiranger alongside their rival, the Rinjuken warriors Rio and Mele.
 * Further, with the main Gokaiger focused on being Don and Ahim, it is no coincidence that both Gokaiger Gokai Changes early on with the other side of the team focus on teams with lions: Rio, the main rival of the Gekiranger and the leader of the Rinjuken forces, has a theme of a lion; and with Rio as part of the "other" focus team, it allows for focus on the other team (the Gekiranger themselves; or in this case Gokai Green and Gokai Pink)
