- This article is about the in-universe location. For the anime volume, see Pendulum Room (volume).
Pendulum Room is a room on Kami's Lookout that allows a person's mind to travel to any place at any point in time.
Later, in the Dragon Ball Z episode "Pendulum Room Peril", Krillin, Tien Shinhan, Chiaotzu and Yamcha use the room to travel to Planet Vegeta over a hundred years in the past and fight two Saiyans named Shorty and Scarface. It is revealed that it is impossible to be killed in the Pendulum Room despite what events may occur in the visions the room induces.
The Pendulum Room is named for the huge pendulum swinging back in forth in it. The pendulum swings over a ring, which a person must stand in if he or she wishes to be transported by the pendulum.
The Pendulum Room is a battle stage in Dragon Ball Z: Taiketsu.
- The Pendulum Room does not exactly allow the user to travel back in time in a typical sense; their mind is joined in an outward manifestation of what each person believes everything to be.
- In the 11th episode of the Imperfect Cell Saga, Mr. Popo calls the Hyperbolic Time Chamber the Pendulum Room. The narrator makes the same error at the end of the 13th episode of the saga.
