He is wound tragic cycling motor accident and the only way to save him by turn his body mangled into a cyborg . Mr . Yoshimora is he nemesis . The team trooper that always getting into trouble and needs to be saved . Is he brave or incredibly stupid ? See useless wheels on legs spin in round circles . Under the Helmet . Yuki " Suzuki " Muchizuki was a hardworking motorcycle courier in the Japanese city of Sapporo . One afternoon , on the way to deliver blueprints to the Yoshimora Architectural Corporation , Yuki Suzuki got caught in a traffic jam . Stressed out , exasperated , and running late , the always - reliable courier impatiently revved up his idling bike and angrily tore off his helmet , when a slow - moving backhoe came out of nowhere and struck Suzuki ' s back tire . The impact sent Yuki flying - and unfortunately , the unlucky runner had just removed his helmet . In a grievous display of poetic justice , Yuki Muchizuki would end up wearing a helmet for the rest of his life . Cracked skull and shattered limbs , Yuki was a mess . On top of his severely lame condition , the young man ' s cold - hearted employer refused to grant him worker ' s compensation because Yuki had violated company policy by not wearing safety gear . But rumors of the young man ' s industrious nature and nearly perfect punctuality reached Robo Dynamics ' s talent scouts , so the cyborg conglomerate made a generous offer to rebuild Muchizuki ' s chassis for free . In a painkiller - induced haze , he accepted the organization ' s proposal . Robo Dynamics President , Obe " G5 " Shiraishi , the ingenious mind behind Generation - 5 cyborgs , took the young man into his home while the company ' s top - notch team of electro - mechanical experts replaced Suzuki ' s useless body parts with cyber - kinetic materials . Muchizuki ' s bone structure was refurbished , remolded with a lightweight titanium frame . His face was fitted with stainless - steel plates . And the vital intelligence wires implanted in his jigsaw skull were girded with an indestructible blue helmet . During the time of Force Trooper Robo ' s rehabilitation , Robo Dynamics had two other young robots on the factory line ; coincidentally , all three Robo Troopers were sent to the Tokyo Police Force to become crime fighters on the same day . Force Trooper Robo enjoyed a brief , but productive career with the Tokyo Police Department until fate threw him another fateful bout of gridlock , this one mental . According to a Robo Dynamics official who spoke under the condition of anonymity , it happened when Force Trooper Robo ( who is always landing the other Robo Troopers in trouble ) was indulging in one of his favorite guilty pleasures : gambling . He was feeling lucky , and won a lot of money ; apparently his ego got so bloated he began boasting about his winnings to a nearby suited man . Force Trooper Robo didn ' t realize that the man was Ibuka Yoshimora , the owner of the architectural firm he ' d been delivering blueprints to on the day of his accident . Force Trooper Robo also didn ' t realize that Mr . Yoshimora had a nasty reputation as a prickly shyster . So when Mr . Yoshimora challenged the braggart Trooper to a contest of wits , daring him to solve a riddle that " has stumped many braver and more intelligent men , " Force Trooper Robo arrogantly accepted the challenge . The brand - new cyborg even bet three Tokyo Police - issued motorcycles that he could solve the riddle . Mr . Yoshimora laughed diabolically and asked , " What goes up the chimney down , but can ' t go down the chimney up ? " * Force Trooper Robo was immediately at a loss , suffering from in problem - solving congestion , and after much inglorious begging and pleading , the mysterious gentleman left the casino with three Tokyo Police motorcycle . When his bosses found out about the loss of police property and gambling on the job , Force Trooper Robo resigned from his position as an urban crime fighter and joined his fellow ex - policeman Atomic Trooper in the Kaiju Big Battel federation . Force Trooper Robo ' s enjoys his new life as a crime fighter in Kaiju Big Battel , but he has not forgotten about his unsettled business with Mr . Yoshimura .
