《七龍珠Z 最強對最強》（日語：ドラゴンボールZ とびっきりの最強対最強，英語：Dragon Ball Z: The Incredible Mightiest vs. Mightiest）是《七龍珠》系列於1991年7月20日上映的第8部劇場版動畫，同時也是《七龍珠Z》第5部劇場版。在劇場版系列中具有特殊意義，因為它首度出現「連接劇情」的設定——以弗利沙被悟空打敗的事件作為背景，進一步衍生出全新的故事線。

劇情的主軸圍繞在弗利沙的兄長「克維拉」（Cooler）。當他得知弟弟死於悟空之手後，便帶領屬下克維拉機甲戰隊——沙維札、內茲、德雷——來到地球，意圖為弟弟報仇並親手除掉悟空。與弗利沙不同，克維拉不僅擁有更冷酷的心思，也展現出更為沉著與算計的一面。他對悟空的仇恨並非單純來自兄弟情感，而是出於家族榮耀以及自我驕傲被踐踏的羞辱感。

悟空與Z戰士們在面對克維拉與機甲戰隊的強襲時，戰鬥過程緊張激烈。比克、克林、悟飯等人接連陷入險境，而克維拉也逐步展現出超越弗利沙的力量。最終，當悟空被逼到絕境時，他體內的超級賽亞人之力再次爆發，與克維拉展開正面對決。值得注意的是，克維拉的戰鬥形態還能進一步進化，展現出不同於弗利沙的全新姿態，這使得對戰的張力大幅提升。最終，悟空憑藉堅毅意志與超級賽亞人的壓倒性力量，成功擊敗克維拉，為地球再一次帶來和平。

在市場評價方面，因為「弗利沙的兄長」這一全新角色設定而引起高度關注。觀眾普遍認為克維拉在性格與氣場上與弗利沙有所區別，他少幾分弟弟的張揚與戲劇化，多幾分冷酷與策略性，因此塑造出另一種截然不同的反派形象。克維拉不僅填補「超級賽亞人誕生後誰能成為新威脅」的空白，也為劇場版提供嶄新的格局。尤其是克維拉進化形態的登場，被視為當時動畫在角色設計上的一次大膽突破，給觀眾帶來極強的視覺震撼。

另一方面，觀眾對本片的戰鬥場面也給予高度評價。超級賽亞人悟空的全力爆發與克維拉的進化對決，被認為是劇場版最經典的名場面之一。然而，部分評論指出，儘管設定新鮮，但劇情仍略顯簡單，主要依賴戰鬥推動故事發展，角色內心描寫相對不足。不過，這樣的風格也符合《七龍珠》系列一貫的熱血基調，對於當時的觀眾而言，反而更能滿足期待。

整體來說，《七龍珠Z 最強對最強》是兼具視覺衝擊與新鮮設定的劇場版作品。克維拉的登場不僅延伸弗利沙一族的神秘感，也進一步突顯超級賽亞人力量的意義，使悟空與克維拉的對決成為影迷心中難忘的經典。這部作品在90年代初的《七龍珠》熱潮中扮演推波助瀾的角色，成功地在影史上留下屬於它的鮮明印記。

Dragon Ball Z: The Incredible Mightiest vs. Mightiest (Japanese: ドラゴンボールZ とびっきりの最強対最強, English: Dragon Ball Z: The Incredible Mightiest vs. Mightiest) is the eighth theatrical film in the Dragon Ball series, released in Japan on July 20, 1991, and the fifth film under the Dragon Ball Z title. This installment holds special significance within the movie franchise, as it is the first to introduce a “continuity-linked” narrative—directly following the events of Frieza’s defeat at the hands of Son Goku, and expanding the storyline into new territory.

At the heart of the plot is Cooler, the elder brother of Frieza. Upon learning of his sibling’s death at Goku’s hands, Cooler sets out for Earth, leading his own elite squad, the Cooler Armored Squadron—consisting of Salza, Neiz, and Doore—with the intention of avenging Frieza and personally eliminating Goku. Unlike Frieza, Cooler is portrayed as a far colder, more calculating, and strategically-minded adversary. His hatred toward Goku is not rooted in brotherly affection but rather in family honor and wounded pride, seeing Frieza’s downfall as a stain on his own legacy.

The battles that unfold are intense and high-stakes. Goku, along with the Z Fighters—Piccolo, Krillin, and Gohan—struggle under the relentless assault of Cooler and his squad, with each of them pushed to their limits. Cooler gradually reveals powers that surpass even those of his younger brother, and the situation grows increasingly dire. When Goku is finally cornered, his Super Saiyan power erupts once again, setting the stage for a direct clash with Cooler. In a striking twist, Cooler unveils a unique transformation distinct from Frieza’s final form, amplifying both his menace and the dramatic tension of the fight. Ultimately, Goku’s unyielding spirit and overwhelming Super Saiyan strength enable him to overcome Cooler, restoring peace to Earth once more.

In terms of reception, the film garnered widespread attention for introducing “Frieza’s brother” as a brand-new character. Fans and critics alike noted the stark contrast between Cooler and his younger sibling: where Frieza was flamboyant and theatrical, Cooler came across as colder, more disciplined, and far more methodical. This distinction established Cooler as a unique villain in his own right, filling the narrative gap of “who could possibly rival the newly emerged Super Saiyan” and providing the theatrical run with a refreshing new scope. Cooler’s transformation in particular was hailed as a bold and visually striking design choice, leaving a strong impression on audiences at the time.

The film’s action sequences also received high praise. The explosive showdown between Super Saiyan Goku and Cooler’s evolved form is still regarded as one of the most iconic battles in the Dragon Ball Z movie lineup. However, some critics observed that the story itself remained relatively straightforward, relying heavily on combat sequences with limited character development or emotional depth. Even so, this approach aligned with Dragon Ball’s established tone of fast-paced, high-energy action, satisfying the expectations of its audience during its release.

Overall, Dragon Ball Z: The Incredible Mightiest vs. Mightiest stands out as a theatrical work that combined visual spectacle with inventive new elements. Cooler’s introduction not only expanded the mystique of the Frieza lineage but also highlighted the growing significance of the Super Saiyan legend. The clash between Goku and Cooler became an unforgettable highlight for fans, and the film played a notable role in sustaining the momentum of Dragon Ball’s massive popularity in the early 1990s, securing its place as a memorable entry in the franchise’s cinematic legacy.
