Red Smogy appeared one day in the skies of Japan with the Scientific Defense Guard trying to disperse the cloud. However, the weather phenomenon proved more difficult to disperse even with missiles failing to do anything. After Kei acquired a sample of Red Smogy, a second attempt to break up the cloud was initiated only to fail once again with the smog turning into a gigantic cyclone. The smog sample was sent to a laboratory on the base with Hiroki helping the scientists, soon discovering that the gas was actually alive. Shortly after Hiroki told the other members of the Scientific Defense Guard, Red Smogy was floating toward a rain storm around one of the local mountain sides. The scientists quickly discovered that water changed the gas sample drastically and shortly after the smog cloud would reveal Red Smogy's true form. As Scientific Defense Guard attacked the rampaging monster it was to little avail as he kept violently attacking the countryside. After a failed attempt to defeat him underwater, Red Smogy attacked a nearby dam which forced Choichiro to turn into Ultraman Joneus. Shortly into the fight Joneus mercilessly beaten Red Smogy until he managed to pin him to a nearby mountain. After flying into the stratosphere Joneus used his Planium Beam to disperse the clouds so that Red Smogy could turn into a smog cloud. Upon this occurring Joneus transported Red Smogy into space.
