《七龍珠Z 激鬥！！100億能量戰士們》（日語：ドラゴンボールZ 激突!!100億パワーの戦士たち，英語：Dragon Ball Z: Return of Cooler）是《七龍珠》系列的第9部劇場版，由東映動畫製作，東映株式會社發行，於1992年3月7日在日本正式上映。影片全片以那美剋星人為背景，帶出克維拉（Cooler）這位強大反派的再臨，故事既承接弗利沙篇的脈絡，又在視覺上創造出新鮮的機械化反派，帶來不同於以往的危機感。全片最終票房約16億日元，觀影人數超過330萬人次，成績相當亮眼。

故事情節發生在《沙魯遊戲》正式展開之前的空檔期。隨著丹迪成為地球的新天神，那美剋星人被神龍送往新那美剋星，他們在這片陌生卻安穩的土地上展開新生活。然而，這份和平並沒有維持太久，一顆龐大的金屬星球「比克斯達星」突然自宇宙深處飛來，宛如巨獸般將新那美剋星籠罩，並試圖吞噬這顆綠色的星球。面對即將再度到來的滅亡危機，丹迪向悟空與Z戰士們發出求援，悟空、貝吉塔、比克、克林與悟飯等人搭乘太空船奔赴現場。

當眾人抵達新那美剋星後，驚訝地發現比克斯達星的操縱者竟是已被悟空打敗的弗利沙之兄——克維拉。原來在與悟空決戰敗亡後，克維拉僅存的腦部碎片在宇宙中漂流，最後與比克斯達星的主電腦融合，重獲新生，化為「金屬克維拉」。透過比克斯達星強大的科技，他製造出無數金屬分身「金屬克維拉軍團」，並以壓倒性的數量與力量展開大規模進攻。悟空與Z戰士們因此陷入前所未有的苦戰，戰鬥逐步升級為激烈的團隊戰，而非以往單一英雄對抗反派的模式。這也是劇場版首次讓貝吉塔登場參戰，並與悟空並肩對抗共同的敵人。

在市場評價上，因為引入「金屬克維拉」這一全新設定而受到觀眾高度關注。與之前單一強敵的劇場版相比，本作更強調「量」帶來的壓迫感——無數金屬克維拉的出現，讓Z戰士們面臨幾乎無窮無盡的敵軍，視覺上帶來極大的震撼。觀眾對本片的戰鬥規模與張力普遍給予好評，特別是悟空與貝吉塔在大銀幕上首次並肩作戰，成為影迷心中極具象徵意義的名場面。

然而，部分評論指出，雖然戰鬥場景華麗壯觀，但劇情內容仍然相對簡單，更多是以戰鬥堆疊來營造緊張感，角色心理描寫與劇情深度稍顯不足。不過對於當時的觀眾而言，這種高強度的戰鬥與極具魄力的反派已足以滿足期待。本作也被視為《七龍珠Z》劇場版逐步從「單挑決戰」轉向「團隊合作」的重要轉折點，並藉此奠定日後劇場版群戰風格的雛形。

整體而言，《七龍珠Z 激鬥！！100億能量戰士們》憑藉金屬克維拉的強烈存在感、壓倒性的分身軍團以及首次加入劇場版的貝吉塔，成功在影迷間留下深刻印象，不僅延續《七龍珠Z》在90年代初期的高人氣，也進一步強化該系列劇場版的戰鬥美學與視覺震撼。

Dragon Ball Z: Return of Cooler (Japanese: ドラゴンボールZ 激突!!100億パワーの戦士たち, lit. Dragon Ball Z: Clash!! The 10 Billion Power Warriors) is the ninth theatrical film in the Dragon Ball series, produced by Toei Animation and distributed by Toei Company. It premiered in Japan on March 7, 1992. The film is set against the backdrop of the Namekians’ new homeworld and marks the dramatic return of Cooler, a powerful antagonist. By connecting to the legacy of the Frieza Saga while introducing a fresh mechanized villain, the story delivered a new sense of danger distinct from earlier installments. The film grossed around 1.6 billion yen at the box office and drew over 3.3 million viewers, making it a commercial success.

The story takes place during the brief period before the Cell Games officially begin. After Dende becomes the new Guardian of Earth, the Namekians are relocated to a new homeworld by Shenron and resume a peaceful life. However, their stability is suddenly shattered when a massive metallic planet, known as the Big Gete Star, descends from the depths of space and begins to envelop the new Namek as if swallowing it whole. Faced with the threat of another extinction, Dende calls upon Goku and the Z Fighters for help. Responding to the plea, Goku, Vegeta, Piccolo, Krillin, and Gohan set out in a spaceship toward New Namek.

Upon arrival, the group is shocked to discover that the mastermind behind the invasion is none other than Cooler, Frieza’s brother, who was previously thought to have been destroyed by Goku. After his defeat, fragments of Cooler’s brain drifted through space until fusing with the central computer of the Big Gete Star, resurrecting him as “Meta-Cooler.” With the advanced technology of the star at his disposal, Cooler generates an endless army of robotic duplicates known as the Meta-Cooler Corps. Overwhelmed by sheer numbers and the immense strength of their foe, the Z Fighters find themselves drawn into an unprecedented large-scale battle. Unlike earlier Dragon Ball Z films that focused on one-on-one duels, this installment emphasized teamwork, with Vegeta making his first appearance in a theatrical release and fighting alongside Goku against a shared enemy.

In terms of reception, the introduction of Meta-Cooler was a major draw for audiences. Compared with prior films that revolved around a single villain, Return of Cooler stood out for its overwhelming “quantity factor”—the endless swarm of Meta-Coolers created a sense of inescapable danger and amplified the scale of combat. Viewers widely praised the film’s action sequences and intensity, particularly the symbolic moment of Goku and Vegeta fighting side by side on the big screen, which has since become one of the franchise’s most iconic scenes.

On the other hand, some critics noted that the narrative was relatively simple, relying heavily on successive battle sequences to drive tension, with limited focus on deeper character development or story complexity. Nevertheless, for audiences at the time, the relentless action and imposing villain were more than enough to deliver an engaging cinematic experience. The film is often regarded as a turning point in the Dragon Ball Z movie lineup, shifting away from solo showdowns toward ensemble-driven battles and laying the groundwork for the cooperative combat style seen in later entries.

Overall, Dragon Ball Z: Return of Cooler left a lasting impression among fans thanks to the imposing presence of Meta-Cooler, the terrifying swarm of duplicates, and the historic moment of Vegeta’s first theatrical appearance. It not only carried forward the immense popularity of Dragon Ball Z during the early 1990s but also elevated the franchise’s movie aesthetic with grander scale battles and striking visual spectacle.
