Gou Fukami

''Excitement, my style, to the limit of my will! "Iron Will," GekiViolet!''

Gou Fukami (深見 ゴウ, Fukami Gō) is GekiViolet (ゲキバイオレット, GekiBaioretto), the fourth member of the Gekirangers and a Fierce Beast Wolf-Fist (激獣ウルフ拳, Gekijū Urufuken) user.

Gekiranger
He is Retsu Fukami's older brother, and very protective of his well-being since their parents died and they spent their childhood at a church. It was there that Gou forced Retsu to promise never to take on the Beast-Fist before leaving to face Rio and never be seen again. It was originally believed that Gou had been killed by Rio, the two original students under Sha-Fu as well as best friends. But in truth, Gou used an imperfect form of the forbidden Gekiwaza in an attempt to defeat Rio as the Fist Sages had done to seal the Fist Demons long ago. But it failed and Gou had been wandering for fifteen years in his resulting werewolf form that he could not control, nor does he have any recollection of what he was doing during that time.

Once regaining his human form, Gou was shocked to find the changes that occurred. He was also a bit vexed to find Retsu disobeyed him and took up Fierce Beast-Fist. Though he is of the Fierce Beast Fist, Gou lacks a passion for justice and fights only for himself. This resulted in Gou mastering a personal and dangerous form of Fierce Ki that he developed himself, called Violet Fierce Ki (紫激気（しげき）, Shigeki) as well as reinvent the Wolf-Fist into his personal Fukami-Style (深見流, Fukami-ryū), a form of the actual Wolf-Fist that uses Muay Thai fighting moves. However, Sha-Fu believed that Gou actually does have a passion for justice deep down, and gave him the Beast-Fist Henshin Brace GongChanger he commissioned specially for Gou to use. After much soul searching and cajoling by the others, he agrees to become GekiViolet and eventually overcome the beast within him thanks to Fierce Beast Fly-Fist Bae. However, Gou still desires to defeat Rio and prove himself as his rival, holding some animosity towards Jan Kandou whom Rio sees as rival, due to being the son of his mentor, Dan. But once he fails a second time to defeat Rio after mastering the strongest Gekiwaza, Gou accepts that he can't be Rio's rival and glad to see him joining up with them in the fight again Long.

During the final battle, Gou is amongst the other Fierce Beast Fist warriors, including the Fist Sages, keeping Long at bay until Jan, Ran Uzaki, and Retsu Fukami return. He watches as his younger brother, Retsu, along with Jan and Ran, defeat Long and seals his powers. After the battle is over, Gou sets off on his own journey with Bae at his side to uncover what he did were as a werewolf. Jan meets him along the way and gives him a final farewell before the two go their separate ways.

Using his Violet Fierce Ki to a degree, Gou can summon GekiTiger and GekiJaguar and control Beast-Fist Giant GekiTohja Wolf on his own.

Gokaiger
A few years later, Gou fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada.

Super Hero Taisen
Gou, alongside his team (Rio and Mele were absent), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

GekiBeasts

 * GekiWolf

Arsenal

 * Beast-Fist Henshin Brace GongChanger

Wolf-Fist Gekiwaza
These Gekiwaza are enhanced by Gou's personal Muay Thai moves, titled his "Fukami-style", requiring the Violet Fierce Ki.
 * Savage-Savage Elbow (蛮蛮肘): GekiViolet's Gekiwaza that elbows the opponent's forehead.
 * Super Savage-Savage Elbow (超蛮蛮肘): GekiViolet elbows the opponent's forehead from a jump.
 * Wolf-Wolf Kick (狼狼蹴): GekiViolet's Gekiwaza that kicks opponent upside the head.
 * Hard-Hard Attack (剛剛撃): GekiViolet makes a ring-like battlefield using the GongChanger, and attacks opponents.
 * Rigid-Rigid Fist (厳厳拳): GekiViolet channels Violet Fierce Ki through the GongChanger and delivers a punch.
 * Rise-Rise Fist (昇昇拳): GekiViolet channels Violet Fierce Ki through the GongChanger and delivers an uppercut.
 * Wheel-Wheel Fist (輪輪拳): GekiViolet performs a powerful uppercut charged with Violet Fierce Ki.
 * Wolf-Wolf Bullet (狼狼弾): GekiWolf jumps at the enemy in a spinning attack, slashing with its bladed tail.

Modified Gekiwaza

 * Come-Come Beast (来来獣): GekiViolet uses this to summon GekiWolf. He has modified it to summon duplicates of GekiTiger and GekiJaguar. This technique is rather different from the other Gekiranger who use it to summon all three of each of their personal Gekibeasts.

Shared Gekiwaza

 * Super Brother Attack (スーパーブラザー撃): Super GekiBlue and GekiViolet's attack.
 * Five Combined Work (五合業): A Gekiwaza which five Gekirangers rush to an opponent while making GekiYellow into a head and spouting each Ki.
 * Beast-Beast Full-Body Change (獣獣全身変): A forbidden Gekiwaza that transforms a user of the Fierce Beast-Fist into an anthropomorphic animal form relating to his/her fighting style, becoming much stronger. This Gekiwaza was used long ago by the Fist Sages to defeat the Fist Demons, assuming their current forms as a result. Bae and Gou also used this move in their respective battles prior to the series. However, due to an imperfect aspect while performing the Gekiwaza, the two each ended up in a flawed form, though only Gou has been able to regain his original human form.

Rhinoceros-Fist Gekiwaza

 * Heaven and Earth Diaster Strike (天地転変打): The most powerful Gekiwaza, mastered by Brusa Ee, it's very power defies the laws of nature. Through Michelle Peng, Gou mastered the Gekiwaza with intent to use on Rio in vain.

Ranger Key
The GekiViolet Ranger Key (ゲキバイオレットレンジャーキー) is Gou Fukami's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The GekiViolet Ranger Key was mainly used by Don Dogoier (Gokai Green), who used it to fight as GekiViolet.
 * When the Gokaigers (bar Joe) became the Gekirangers while fighting Action Commander Zodomas' Zugormin.
 * When the Gokaigers became the Gekirangers in their fight with Cosmic Kenpō Master Pachacamac XIII.
 * When the Gokaigers became the Gekirangers while fighting Action Commander Zakyura.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Gou received his key and became GekiViolet once more.

Roll call
After transforming into Geki Violet, Gou says "Excitement, my style, to the limit of my will! 'Iron Will,' Geki Violet!" (刺激、俺流、わが意を尽くす 「アイアン・ウィル」 ゲキバイオレット！).
