Story
Four thousand years ago in Ancient China, a form of Chinese styled-like kenpō martial arts called Jūken (獣拳) was developed. It was created by a man named Bruce Ee, who came to Japan and built the hidden village Jūgenkyō (獣源郷). Jūken is a martial art in which one mimics the abilities of animals as well as trying to attain spiritual peace. However, dissent grew among the creator's ten students. Three of them believed that they should use the suffering and hatred harnessed within humans to increase their power, using their power to assume their monstrous forms; the Three Kenma. After Brusa Ee was murdered, the Kenma gathered followers to practice an evil form of the Jūken style known as Rin Jūken Akugata. The other seven students believed that true strength should come from within and engaged their former friends in a great war, ending the fight with a forbidden technique to seal the Kenma powers at the cost of losing their human forms in the process, becoming the Seven Kensei. Followers of the Kensei created the Geki Jūken Beast Arts school: the Jūken of justice whose sport discipline enhances the human body with the self-produced positive Qi called "Geki." It is taught by Grand Master Sha Fu, one of the Seven Kensei, using a sports goods company named SCRTC (スクラッチ) as a front. Presently, a fallen student from the Geki Jūken school named Rio turned to the Rin Jūken style. He rebuilds the Rinjū Hall and brings the long-dead Rin Jūken users back to life as kyonshi to collect Rinki, Geki's polar opposite Qi, to resurrect the Three Kenma so that through them, he can become stronger. To fight the new Rinjū Hall, Sha Fu trained two youths: Ran Uzaki and Retsu Fukami. Along with Jyan Kandou, a feral boy raised by tigers in the woods near Jūgenkyō, the Gekiranger team is formed and later joined by two other Geki Jūken users, Gou Fukami, Retsu's brother and master of the Geki Jū Wolf-Ken style, and Ken Hisatsu, a genius master of the Geki Jū Rhinoceros- style, to save the world from the Akugata's ambitions. However, an even greater evil uses the two sides for its plan.

Main

 * Gekirangers: Students and associates of the Geki Jūken Beast Arts martial arts schools. The primary Gekirangers utilize the Geki Changer (ゲキチェンジャー) arm guards, which harness and amplify their Geki, to transform and store their weapons, such as the Geki Bazooka (ゲキバズーカ). After becoming Super Gekirangers, they gain the use of the Super Geki Claw (スーパーゲキクロー) and jet engine-like vents on their suits that channel their Kageki and enable various feats of speed and aerial maneuverability. Furthermore, the Gekirangers can use their Geki to manifest the auras of their fighting styles' totem animals into physical forms and combine them to form Kenpō Giants (拳法巨人).
 * Jyan Kandou (漢堂 ジャン): A feral child raised by tigers in the forest outside the Beast Origin Village (獣源郷) who narrowly survived an attack by Long, who intended to kill him due to his lineage, and repressed the memories of the incident. As a result of his upbringing, Jyan's vocabulary became limited, leading to him incorporating "Jyan-ish" phrases such as "niki-niki", "zowa-zowa", and "waki-waki" in his speech. In the present, Master Xia Fu begins training Jyan as the latter embodies the "Unbreakable Body" (アンブレイカブル・ボディ) aspect of Geki Jūken, which allows him to withstand most forms of pain, but requires assistance in mastering the Heart aspect. Soon after, Jyan joins the Gekirangers as Geki Red (ゲキレッド) and becomes a practitioner of the Geki Jū Tiger-Ken (激獣タイガー拳) and Geki Jū Shark-Ken styles. While transformed, he wields the Geki Nunchaku (ゲキヌンチャク) and the Geki Sabers (ゲキセイバー). As Super Geki Red (スーパーゲキレッド), Jyan embodies the "Extremely Unbreakable Body" (過激にアンブレイカブル・ボディ) aspect of Geki Jūken and utilizes the Geki Jū Gorilla-Ken style. Jyan Kandou is portrayed by Hiroki Suzuki (鈴木 裕樹) as a young adult and Arashi Fukasawa (深澤 嵐) as a child.
 * Ran Uzaki (宇崎 ラン): An employee of SCRTC who comes from a high-class family and initially focuses heavily on her willpower and keeping her heart in the highest place, to the point where she embodies the "Honest Heart" (オネスト・ハート) aspect of Geki Jūken. However, a combination of these and her inability to attend to small details leaves her technique lacking. In time, she becomes happier and more relaxed and is appointed leader of the Gekirangers. Additionally, she is a practitioner of the Geki Jū Cheetah-Ken (激獣チーター拳) and Geki Jū Elephant-Ken styles. As Geki Yellow (ゲキイエロー), she wields the Geki Tonfa (ゲキトンファー) standard-issue weapon in its Long Baton (ロングバトン) configuration and the Geki Hammer (ゲキハンマー). As Super Geki Yellow (スーパーゲキイエロー), she embodies the "Extremely Honest Heart" (過激にオネスト・ハート) aspect of Geki Jūken and utilizes the Geki Jū Penguin-Ken style. Ran Uzaki is portrayed by Mina Fukui (福井 未菜).
 * Retsu Fukami (深見 レツ): An intelligent yet solitary, selfish, and seemingly cold SCRTC employee who holds a grudge against Rio, who he believes killed his brother Gou when he was a child. In pursuit of seeking revenge, Retsu set aside an artistic career to study his brother's fighting style, but believes winning should be like a painting; complete and inspirational. Due to prioritizing his techniques in his training, to the point where he embodies the "Fantastic Technique" (ファンタスティック・テクニック) aspect of Geki Jūken, Retsu's attention to beauty costs him stamina, leaving his body at a disadvantage until he defeats Master Bion Biao in an endurance match and obtains Kageki. Additionally, Retsu is a practitioner of the Geki Jū Jaguar-Ken (激獣ジャガー拳) and Geki Jū Bat-Ken styles. As Geki Blue (ゲキブルー), he wields the Geki Tonfa in its standard dual tonfa configuration and the Geki Fans (ゲキファン). As Super Geki Blue (スーパーゲキブルー), Retsu embodies the "Extremely Fantastic Technique" (過激にファンタスティック・テクニック) aspect of Geki Jūken and utilizes the Geki Jū Gazelle-Ken style. Retsu Fukami is portrayed by Manpei Takagi (高木 万平) as a young adult, Nao Fujisaki (藤崎 直) as a child, and Sora Kitajima (北島 空) as a baby respectively.
 * Gou Fukami (深見 ゴウ): Retsu's overprotective older brother and a student in Jūken alongside Rio and Miki Masaki. Despite this, Gou initially lacks passion for justice and fights only for himself. This resulted in him developing and mastering a dangerous form of Geki called Shigeki (紫激気（しげき）) and reinventing the Geki Jū Wolf-Ken (激獣ウルフ拳) style into his personal Fukami Style (深見流). After their parents died, Gou forced Retsu to never practice Jūken before leaving to fight Rio using an imperfect form of a forbidden Geki Waza in an attempt to defeat and seal him. However, Gou was transformed into a feral werewolf and wandered the world for fifteen years until he eventually regains his human form and reluctantly joins the Gekirangers as Geki Violet (ゲキバイオレット). Unlike the primary Gekirangers, Gou embodies the "Iron Will" (アイアン・ウィル) aspect of Geki Juken and utilizes the Gong Changer (ゴングチェンジャー) brace in order to transform due to his Shigeki being incompatible with Geki Changers. Gou Fukami is portrayed by Riki Miura (三浦 力).
 * Ken Hisatsu (久津 ケン): A free-spirited martial arts prodigy who trained at the Beast Origin Village and mastered one of the oldest fighting styles in the Beast Arts, the Geki Jū Rhinoceros-Ken (激獣ライノセラス拳), to overcome the pain of losing his mother at a young age. He was originally meant to join Ran Uzaki and Retsu Fukami as their third teammate, but left to travel abroad due to his Geki Changer being broken and his desire to not restrict himself to the Geki Jūken school. Ken eventually returns in the present to aid the Gekirangers in their battle against the Rin Jūken Akugata and Gen Jūken schools as the white-colored Geki Chopper (ゲキチョッパー) before returning to work at SCRTC Meisters once the aforementioned battle is over. Unlike the primary Gekirangers, Ken embodies the "Amazing Ability" (アメイジング・アビリティ) aspect of Geki Jūken and utilizes the SaiBlade (サイブレード) gauntlet in order to transform. In combat, he can utilize the Geki Hard Diamond (激気研鑽) technique, which allows him to channel his Geki over his hand and convert it into a diamond blade, along with Kageki. Additionally, the SaiBlade serves as his primary weapon, can switch between the gun-like SaiBlade Finger (サイブレードフィンガー) mode and the blade-like SaiBlade Cutter (サイブレードカッター) mode, and can combine with the Super Gekirangers' Super Geki Claw to form the Super SaiBlade (スーパーサイブレード), which either Ken or any one of the Super Gekirangers can use to perform a Kageki/Geki Hard Diamond fusion attack. Ken Hisatsu is portrayed by Sotaro (聡太郎).
 * Rio (理央): The leader of the Rin Jūken Akugata school and a practitioner of the Rinjū Lion-Ken (臨獣ライオン拳) style who seeks to gain strength so he can never suffer pain again. He initially joined the Geki Jūken school, trained under Master Xia Fu, and formed a close bond with Gou Fukami, but was dissatisfied with his progress and left to join the Akugata. During this time, he harnessed the power of Rinki to manifest an armored form called Black Lion Rio (黒獅子リオ). Throughout the series, Rio forms a rivalry with Jyan and cultivates Rinki from his fear, hatred, and jealousy before he is overthrown by Maku and manifests Dorinki from his self-hatred. After receiving more power and killing Maku to regain his position, Rio falls under Long's influence and uses the Gen Jūken school's power to transform into Genjū King Rio (幻獣王リオ), gaining mastery over the Genjū Gryphon-Ken (幻獣グリフォン拳) style. Eventually, he discovers Long's treachery and joins forces with the Gekirangers to defeat him, sacrificing himself in the process. Rio is portrayed by Hirofumi Araki (荒木 宏文) as an adult and Shogo Ehara (江原 省吾) as a child.
 * Mere (メレ): A cruel and malevolent practitioner of the Rinjū Chameleon-Ken (臨獣カメレオン拳) style who wields a pair of sais and a tongue-like weapon. Having died during the Geki-Rin Rebellion, Rio used Rinki to revive her as a Rinrinsi and grant her a human form a decade prior to the series due to their similar objectives. As a result, she became highly devoted to him and developed an initially unrequited love for him. She aids Rio in his plans throughout the series, during which she becomes a Vermilion Bird/rooster-themed Genshou with mastery over the Genjū Phoenix-Ken (幻獣フェニックス拳) style while working with the Gen Jūken school, before discovering Long is manipulating Rio and joins the latter in helping the Gekirangers defeat him, sacrificing herself in the process. Mere is portrayed by Yuka Hirata (平田 裕香).

Impressed by Rio's ideals, Kata agrees, though the latter's brutal training methods lead to Mere fearing for Rio's well-being and resurrecting Rageku. Following this, Kata agrees to let her take over Rio's training and leaves for a separate section of Rin Jū Mountain. While taking part in an attack on the Beast Origin Village, Kata withstands most of the Gekirangers' strongest attacks until Jyan Kandou overcomes his illusions. An enraged Kata enlarges and overpowers GekiFire and GekiTohja Wolf, but is killed by SaiDaiOh.

As he possesses tremendous Dorinki from his endless rage, he served as the original leader of the Akugata and can empower his followers. In the past, Maku was infuriated that he was made Brusa Ee's successor on the recommendation of Xia Fu, Ee's first choice, rather than on his own merits. In response, Maku ended his friendship with Xia Fu and, after meeting Long, founded the Akugata, murdered Ee, and started the Geki-Rin Rebellion with the intention of becoming the strongest being on Earth. However, he was defeated by the Kensei and his body was sealed behind a locked door in the Rin Jū Hall. In the present, despite Kata and Rageku's warnings, Rio breaks the seal on the door and resurrects him. Disgusted by the changes that occurred while he was dead, Maku overthrows Rio, resumes his leadership position, and declares a new Geki-Rin Rebellion.
