Terror of the Saucer Race Series - The Fighting Leo Brothers! The End of the Flying Saucer Beast (恐怖の円盤生物シリーズ! 戦うレオ兄弟! 円盤生物の最後! Kyōfu no enban seibutsu shirīzu・Tatakau Reo kyōdai! Enban seibutsu no saigo!) is the 46th episode of Ultraman Leo. It is the seventh episode in the Terror of the Saucer Race Series (恐怖の円盤生物シリーズ Kyōfu no enban seibutsu shirīzu) story arc.
A new powerful saucer creature has been summoned to Earth. Two brothers have an encounter with it, but the police refuse to believe a monster is behind their accident.
Black Directive summons Hungler to earth, and the beast begins to cause accidents which result in traffic jams, one of which Gen is caught in.
While driving home, two brothers, Junji and Junpei, are attacked by the monster. Both survive, but the elder is injured. Most people, however, are convinced the elder was simply speeding and do not believe the story of the monster. Tooru and Ayumi put in a few words in his defence, and they get Gen.
Junji takes them to Junpei, but he distrusts Gen believing that he wants to get him in trouble. Junpei loses his job, and refuses to get Gen involved. Junji takes Gen to the place, but the owner of the land drives them off. Then the monster arises from the ground, unobserved somehow.
Gen takes riceballs to Junji. He tells him that he had a big brother who was killed by the saucer beasts. Junji opens up to him, when Hunglar arrives and begins attacking. People run in terror as it crashes through a bridge and begins inhaling cars.
Gen tells Junji to run as bridges and cars fall around him. He attacks the monster with a giant balloon, causing it to fly away, but is injured. Meanwhile, the monster attacks again. Junpei gets into his truck and kamikazes into the beast. His flaming body is thrown from the debris. Although injured, Gen transforms.
Junpei manages to come to. Leo battles the monster, but his wound proves to much for him. Just when all seems lost Astra arrives. He changes to a small size and destroys the monster from within.
Astra supports Leo and the two fly off, while Junpei and Junji wave enthusiastically to them. Infuriated, Black Directive summons Black Terrina to earth, promising that Leo will die. End..
