"Diligence day by day, refining my heart. Honest Heart~GekiYellow!
The Extremely Honest Heart~Super GekiYellow!"
Ran Uzaki (宇崎 ラン Uzaki Ran) is GekiYellow (ゲキイエロー GekiIerō), who was eventually chosen to be the captain of the Gekirangers. She is an employee of SCRTC and a Fierce Beast Cheetah-Fist (激獣チーター拳 Gekijū Chītāken) artist, using a combination of speed and accuracy in her attacks.
She was appointed by Sha-Fu as the Captain of the Gekirangers. Ran comes from a high-class family that owns a gym, recruited by Sha-Fu with her mother Reiko allowing Ran to join SCRTC until Ran was of age to undergo a marriage interview to ensure her future.
At first, Ran wanted to resign from learning the Beast Arts because she didn't think she was good enough but Sha-Fu told her to think her actions through. She relies more on will than technique when fighting. Upright and cleanhanded, Ran will do things always the right way, being a fighter that gives "Heart" (心 Shin?, also pronounced as Kokoro) the highest place. She excels in speed, but her reluctance to care for the small details make her "Technique" very poor. From learning Master Elehung Gambou's Fierce Beast Elephant-Fist (激獣エレファント拳 Gekijū Erefantoken?) meteor hammer techniques, Ran became more loose and happy in the process.
Ran competes with Michelle Peng in a skateboarding competition (tying at 100 points each) to improve her "Technique" to obtain Extreme Ki. This training allows her to become Super GekiYellow (スーパーゲキイエロー Sūpā GekiIerō?). As Super GekiYellow she uses the Fierce Beast Penguin-Fist (激獣ペンギン拳 Gekijū Penginken?) style and is the "Extremely Honest Heart" (「過激にオネスト・ハート」 Kageki ni Onesuto Hāto?). Soon after, Ran was titled as team captain of the Gekirangers.
These are techniques that Ran uniquely uses.
- Cheetah-Fist Gekiwaza
These Gekiwaza focus on the "Heart" of the user.
- Blink-Blink Bullet (瞬瞬弾 Shun Shun Dan): GekiYellow's Gekiwaza that project her Fierce Ki as GekiCheetah to attack several opponents at high-speed.
- Pierce-Pierce Strike (貫貫打 Kan Kan Da): Another Gekiwaza used by GekiYellow.
- Strike-Strike Bullet (打打弾 Da Da Dan): GekiYellow's Gekiwaza that allows her to punch her opponent in rapid succession.
- Long Baton Extend-Extend Strike (ロングバトン伸伸打 Rongu Baton Shin Shin Da): GekiYellow's Gekiwaza that uses the extensibility of the GekiTonfa Long Baton.
- Mom-Mom Strike (母母打 Mō Mō Da): GekiYellow's Gekiwaza empowered by her mothering skills, landing several blows to the enemy's face. The attack results with the target's head exploding from the massive swelling caused by the attack.
- Super Cheetah Strike (スーパーチーター撃 Sūpā Chītā Geki): A Gekiwaza that utilizes Extreme Ki and the Super GekiClaw.
- Fierce-Extreme Judge-Strike (激烈断打 Gekiran Danda): Secret Gekiwaza.
- Elephant-Fist Gekiwaza
These Gekiwaza are performed through meteor hammer techniques.
- GekiHammer Bullet-Bullet Ball (ゲキハンマー弾弾丸 GekiHanmā Dan Dan Gan): A Gekiwaza that uses the GekiHammer to hit the enemy hard from a long distance.
- GekiHammer Meteor Bullet (ゲキハンマー流星弾 GekiHanmā Ryūsei Dan): A Gekiwaza that uses the GekiHammer.
- Penguin-Fist Gekiwaza
These Gekiwaza focus on the "Technique" of the user and are mainly performed through emulating boardsports and through GekiPenguin.
- Penguin Bullet (ペンギン弾 Pengin Dan): GekiPenguin uses her Jetboard to fly directly at the opponent, assisted by both the Gazelle Kick and Gorilla Wave Gekiwazas.
- Shared Gekiwaza
These are attacks shared within the 'triangle' of GekiRed, GekiYellow and GekiBlue and occasionally added onto by GekiViolet and Gekichopper
- Fierce-Fierce Cannon (激激砲 Geki Geki Hō): A team Gekiwaza performed using the GekiBazooka. Initially, it required two minutes to charge, but they soon overcame this limit. It requires all three Gekirangers to wield, transferring their collective Fierce Ki into the GekiBazooka to fire. The first few times that the Gekirangers used it, Jan Kandou would yell "Pork cube stew!" (豚の角煮 Buta no Kaku Ni), which is the name of the dish that Natsume was preparing for him when he learned how to be patient, but this irritated Ran and Retsu Fukami, so he eventually stopped doing so. If there is insufficient Ki, the cat head will close back up automatically, as shown in a Beast Arts Academy demonstration.
- Super Fierce-Fierce Cannon (スーパー激激砲 Sūpā Geki Geki Hō): This Gekiwaza is identical to the Fierce Cannon, but the Super Gekirangers wield the GekiBazooka.
- Soul-Soul Bullet (魂魂弾 Kon Kon Dan): The three Gekirangers focus their Fierce Ki to over their enture bodies it enters a Fierce Ki Explosive State (激気爆発 Geki Bakuhatsu), charging at their opponents and exposing to them to their Ki at point-blank range.
- Super Double Attack (スーパーダブル撃 Sūpā Daburu Geki): A Gekiwaza which two attack simultaneously utilizing Extreme Ki and the Super GekiClaws.
- Super Triple Attack (スーパートリプル撃 Sūpā Toripuru Geki): A Gekiwaza which three attack simultaneously utilizing Extreme Ki and the Super GekiClaws.
- Three Plan Slash (三算斬 San San Zan): A three-way attack with two Super GekiClaws and the SaiBlade.
- Five Combined Work (五合業 Go Gō Gō): A Gekiwaza which five Gekirangers rush to an opponent while making GekiYellow into a head and spouting each Ki.
These are attacks shared with others.

"Onesuto Hāto," Geki Ierō!). After transforming into Super Geki Yellow, Ran says, "'Extremely Honest Heart,' Super Geki Yellow!"
