Dragon Ball Z: The World’s Strongest

Dragon Ball Z: The World's Strongest is a 1990 anime film in which Gohan and Oolong set out to collect the Dragon Balls, only to find that their radar is tracking a second, unknown party gathering the orbs at the same time. Following the signal leads them toward a massive wall of ice, near the place where Piccolo is training, and into the path of a scheme already well underway.

Behind that scheme is the scientist Dr. Kochin, who has used the summoned dragon to restore his long-lost master. That master, Dr. Wheelo, survives as a brain housed inside a robotic body, and he has a specific goal in mind: he wants to claim the physique of the strongest warrior on Earth for himself.

Because that desire points directly at Goku, the film turns into a confrontation between the Z fighters and Wheelo's forces, with Goku, Piccolo, Gohan, and their companions drawn into the fight. The premise sets martial arts action against a science fiction threat, as the heroes must deal with an enemy whose reach extends far beyond his ruined body.

Dragon Ball Z: The World's Strongest opened in Japanese theaters on March 10, 1990, slotting into the broadcast run of the Dragon Ball Z television series between its 39th and 40th episodes. The film was one of several features screened together at that year's Toei Manga Matsuri festival program, sharing the bill with the second Akuma-kun movie, Welcome to Devil Land, and the 1990 theatrical version of Sally the Witch. It runs about 60 minutes and stands as the second Dragon Ball Z feature, arriving after Dead Zone and before The Tree of Might.

The movie takes the original manga as its source material and presents a self-contained theatrical story blending action, adventure, and science fiction, with martial arts at its center. Its single-installment format and roughly hour-long runtime mark it as a festival companion piece rather than a continuation of the weekly series arc.

An English dubbed version of the film was produced, and it is carried on the Bilibili TV and Crunchyroll streaming services. Its Japanese title is ドラゴンボールＺ この世で一番強いヤツ.

Dragon Ball Z: The World's Strongest is an anime film within the Dragon Ball Z franchise and the second theatrical Dragon Ball Z movie. It follows Dragon Ball Z: Dead Zone in the film line and precedes Dragon Ball Z: The Tree of Might, placing it among the early Dragon Ball Z features released while the television series was airing.

The movie is a self-contained side story rather than a direct adaptation of a manga arc. It uses the series' core cast and concepts, and it fits into the broader Dragon Ball timeline as a theatrical adventure that can be viewed independently. It is not the start of the Dragon Ball franchise, nor does it replace the main Dragon Ball Z series; it is an individual movie entry connected to the larger franchise hub.

Released in Japan in 1990, the film shares the action, adventure, and science fiction elements of Dragon Ball Z, while its shorter runtime and theatrical format distinguish it from the television episodes. Its English dub and streaming availability make it accessible as part of the wider Dragon Ball Z movie catalog.
