Pendulum Room Peril (明日なき街! 勝利への遠い道のり, Asu naki Machi! Shori e no Toi Michinori) is the seventeenth episode of the Vegeta Saga in the uncut Dragon Ball Z series. The episode first aired on August 30, 1989. Its original American air date was November 15, 1996.
After half a year of overcoming emotional and physical hardship, Gohan is finally being trained by Piccolo. Meanwhile, up at Kami's Lookout, Krillin and the remaining Z Fighters are growing impatient with Kami, who, after two months, has still not given any lessons to his pupils. Mr. Popo then takes everyone (excluding Yajirobe) on a mental combat simulation, using an old and mysterious mechanism inside the palace: the Pendulum Room.
There, in the middle of a long-since ruined Saiyan city, Tien Shinhan and the others are attacked by two ferocious Saiyan warriors. The four of them put up a fight, but the odds are hopeless, and they are picked off one by one. Returning to the present, Kami tells the team that their opponents were only half as strong as genuine Saiyans. Rather than being frightened off by this revelation, the prospects of facing such incredible warriors renews the convictions of our heroes to fight.
- During a later episode in the series King Kai says that the gravity on Planet Vegeta is over 10 times Earth's gravity but when Mr. Popo sends Krillin, Yamcha, Tien and Chiaotzu to the planet in the Pendulum Room, they all seem to be unaffected by this (whereas Goku can barely stand in the identical gravity on King Kai's planet). However, the original Japanese version makes no explicit comments that the place they have been sent to is Vegeta.
