Beast-Men

When a fighter of the Akugata performs the Ringi Beast-Man Wicked Body Change, he/she turns into a Beast-Man (獣人, Jūjin), a fighting form of the Rinrinshī that resembles his/her Confrontation Beast-Fist style's animal and allow him/her to fully utilize that style's Ringi. They are each named putting the first kana of their beast's Japanese name at the end of it (Kamakiri (カマキリ, Kamakiri) is Japanese for Praying mantis).

Rinrinshi
The Rinrinshi (リンリンシー, Rinrinshī) are high ranking Rinshi who pass the Chamber of Trials (試しの房, Tameshi no Bō), allowed to remove the mask as the animal signature to his/her fighting style forms on the forehead and gain a new attire to signal the rank. Rinrinshi can obtain Beast-Man form, but only for a short amount of time depending on the level of Confrontation Ki amassed inside. However, the Rinrinshi empowered by Maku's power can assume Beast-Man form for an indefinite amount of time. Like the Rinshi, the Rinrinshi die as their bodies petrify and explode in violent bluish flames.

Makirika
Makirika (マキリカ, Makirika, 1-2): The first Rinrinshī the Gekirangers faced, master of the Confrontation Beast Mantis-Fist (臨獣マンティス拳, Rinjū Mantisuken) style which allows him to cut through any material with his forearms. Due to his fighting style, Makirika tends to calls an enemy's death a "prayer". Makirika is sent to retrieve the "Fist Demon Bracelet" from Miki Masaki before she could make it to the Beast Origin Village, with Jan Kandou caught in the crossfire. He later attacked the city and was man-handled by Jan before being easily defeated non-violently by Master Sha-Fu, but, obtaining a second chance with Mele's help, unconcerned with the detrimental side effects of her Infinite-Violent Wave Ringi as he tore down the dam to flood the city and invoke fear on the masses. In the end, he is destroyed by Beast-Fist Giant GekiTohja's Great Firm-Firm Fist.

Gyuuya
Gyuuya (ギュウヤ, Gyūya, 3): A user of the Confrontation Beast Buffalo-Fist (臨獣バッファロー拳, Rinjū Baffarōken) style who just got promoted to the rank of Rinrinshī after he passed the Chamber of Trials. His fighting style emulates the buffalo's raw power to deliver destructive charges to the opponent. With his powerful thighs and Confrontation Ki-charged horns, Gyuuya can easily break through solid walls. He overpowered Jan in round one, but is forced to retreat as he was not used to being a Rinrinshī. After enough training, Gyuuya returned to resume the fight, only be beaten by the new attacks Jan learned from passing the Cleaning Training Sha-Fu put him through. Though he assumed to have defeated GekiTohja, Gyuuya is destroyed once he unknowing helped GekiTohja in using the Great Firm-Firm Leg.

Five Venom Fists
Five Venom Fists (五毒拳, Godokuken): The Elite Five of the Confrontation Beast Hall, masters of the Confrontation Beast-Fist styles of venomous animals. They each wear a sash as proof of their higher rank above novice Rinrinshī. They arrived in Lesson 3 at Rio's call to destroy the Gekirangers, which they saw as a "waste of their talents" after easily beating them. However, their defeat by the Gekirangers in the Poison Match enraged the Venom Fists. But it turned out that Rio had a second, hidden motive in summoning the Venom Fists: To kill the one who possess the Ringi technique True Poison, the "ultimate poison", and take it as his own.

Living Beast-Men
Unlike their undead counterparts, the living Beast-Men have no Rinrinshī form. They are usually the strongest/oldest students of the Akugata or the personal guard of their Fist Demon masters. They explode in crimson flames upon death.

Confrontation Machine Soldiers
The Confrontation Machine Soldiers (臨機兵, Rinkihei) are the Akugata's personal beetle-based Terracotta Army hidden within Confrontation Beast Mountain. Two such statues were originally located at the altar in the Confrontation Beast Hall Dojo, eventually brought to life by Rageku and Kata's Confrontation Ki to assist Rio in his search for the other Fierce Beast-Fist users, assuring no interference in his fights. They are the Super Gekirangers' first opponents. Maku would later pick out another set, bringing them to life with Fury Confrontation Ki and transformed into red-armored versions called the Fury Confrontation Machine Soldiers (怒臨機兵, Dorinkihei). In episode 36, a Rinshī dons a Butoka as a suit of armor to obtain the Raspberry Diamond, and was later killed by SaiDaiOh.
