Dragon Ball Z: Atsumare! Gokū Wārudo (ドラゴンボールZ あつまれ！悟空ワールド, Doragon Bōru Zetto Atsumare! Gokū Wārudo; lit. "Dragon Ball Z: Gather Together! Goku's World") is a Dragon Ball video game released for the Terebikko in 1992 in Japan. Like the anime, Toei Animation was responsible for its footage, and as well each voice actor reprised the role of their characters for its sequences.
As a Terebikko title, Atsumare! Gokū Wārudo was packaged as a VHS tape and a telephone peripheral used to input commands to Goku and friends, and also to answer the group's trivia questions when requested.
Atsumare! Gokū Wārudo tells a feature-length story involving time travel leading up to the group's first encounter with Cell (portrayed slightly differently than in the mainstream series).
The plot of the animation seems as though it could be worked into the mainstream series, particularly in the ten days prior to the beginning of the Cell Games. However, in this special, Gohan as a kid actually meets Cell, instead of being a teenager after having trained with Goku in the Hyperbolic Time Chamber.
Once the group encounters Perfect Cell at the end of the game, a heavy punch to the face by Goku is enough to cause Cell to flee and recover from the blow.

- Goku almost causes a paradox by getting out of the Time Machine to meet himself as a kid, but Trunks drags him away.
- It is unknown if Future Trunks' use of the Time Machine in the game was a violation the Supreme Kai of Time's laws concerning Time Machines, though it is likely a moot point since the game was released in 1992, long before the recent concept of Time Machines being prohibited in the Dragon Ball universe was established in games such as Dragon Ball Online and Dragon Ball Xenoverse, as well as in other media such as Akira Toriyama's manga Jaco the Galactic Patrolman.
- Considering several of the Dragon Ball films are said to take place in alternate timelines in Xenoverse 2, it probably takes place in an alternate timeline (possibly in one of that same timelines as the films such as Super Android 13 or The Return of Cooler as they apparently take place in the same time period and Gohan is still a child). Presumably Chronoa may have chosen to erase its timeline from existence due to the brief interaction between Goku and his past self, due to the potentially dangerous paradox it might create and the fact that the Time Machine was used in such a casual yet dangerous way (as Future Bulma's Time Machine has a design flaw that produces distortions in time that produce alternate timelines, which if left uncheck could cause the Time Vault to exceed its capacity which would result in its destruction, destroying the Universe along with it). Alternatively she or the Time Patrol may have intervened to stop the Time Machine from being used or warned the Future Trunks in that timeline of the danger of using the Time Machine so carelessly.
