Retsu Fukami is GekiBlue of the Gekirangers. He is an employee of SCRTC and a Fierce Beast Jaguar-Fist practitioner.
He was a child when his older brother Gou Fukami was believed to have been killed by Rio. This event traumatized Retsu severely, to the point where years later he still possessed an utter hatred for Rio. He originally had a promising career in painting but took a break to learn the same fighting style as his older brother had to find the same motivation that it gave Gou, rather than out of revenge. Retsu is very intelligent but also selfish, doesn't take interest in others, and gives an impression of extreme coldness, although this changes as the series progresses. He believes that winning should be like a painting, complete and something that moves you. He sometimes mixes English when speaking. He learned of moving sensation of a trance when he mastered Bat Li's Fierce Beast Bat-Fist (激獣バット拳, Gekijū Battoken) style. He knows various "Techniques" (技, Gi, also pronounced as Waza), putting them in first priority when training. His attention to beauty costs him stamina, making his "Body" his weakest point until he competed with Bion Biao in an endurance match (and emerges victorious) to obtain Extreme Ki. This training allows him to become Super GekiBlue (スーパーゲキブルー Sūpā GekiBurū?). As Super GekiBlue, he uses the Fierce Beast Gazelle-Fist (激獣ガゼル拳 Gekijū Gazeruken?) style and is the "Extremely Fantastic Technique" (「過激にファンタスティック・テクニック」 Kageki ni Fantasutikku Tekunikku?).
During the final battle, Retsu is infused with Rageku's Confrontation Ki, and is then brought to an astral Confrontation Beast Hall to master the Confrontation Beast Jelly-Fist (臨獣ジェリー拳 Rinjū Jerīken?), style to seal Long. Three months after Long's defeat, he is seen alongside Ran Uzaki teaching the Beast Fist to young kids at SCRTC.
