While dealing with the kaiju Bango, Sabura Sato realises that the monster has been copying his actions. Gen takes advantage of this by filling Sabura's flexible outfit with hydrogen to inflate like a balloon, which Bango copies as well. A sneezing fit from the monster sends Sabura through the air and breaks the cord he was attached to, though Gen is able to save him by transforming into Leo, by which point Sabura's outfit has fully deflated.
