《七龍珠Z 超級賽亞人孫悟空》（日語：ドラゴンボールZ 超サイヤ人だ孫悟空，英語：Dragon Ball Z: Super Saiyan Son Goku）是《七龍珠》系列於1991年3月9日上映的第7部劇場版動畫，由東映動畫製作，全片長52分鐘，最終票房約為2億5千萬日元。以全新的反派「史拉格」（Slug）為核心，並將劇情與「超級賽亞人」的概念緊密結合，雖然悟空在劇中並未真正完成超級賽亞人的正統變身，但其力量爆發時散發出的金色氣場，卻成為影迷心目中早期「超級賽亞人雛形」的重要象徵。

故事的開端來自一顆不明星體逼近地球，伴隨著濃烈的邪惡氣息，隨後自稱「宇宙大王」的外星人史拉格現身，並企圖奪取地球。他的軍團不僅成功入侵，甚至釋放出黑霧籠罩大地，使得整個星球逐漸失去生機。悟空、比克、克林、悟飯等人奮力抵抗，但在多次交鋒後，依然無法阻止史拉格的陰謀。隨著戰局推進，史拉格利用七龍珠許下願望，恢復年輕與強壯的肉體，實力瞬間暴增，讓Z戰士陷入苦戰。

在最危急的時刻，悟空被激怒後力量突然覺醒，全身迸發出金光，雖未正式變身，卻展現出壓倒性的氣場，硬是將史拉格逼得現出真正的模樣——一個高大而具有壓迫感的那美剋星人。悟空的爆發使戰局逆轉，並最終擊潰史拉格的野心，拯救地球免於毀滅。

在市場評價方面，本作的最大亮點在於「超級賽亞人概念的預演」。雖然劇情中悟空並非真正達到漫畫正篇裡的變身，但其氣場、戰鬥力的瞬間提升，以及視覺上以金光表現出的壓迫感，都讓觀眾感受到「超級賽亞人傳說」即將到來的氛圍。這一橋段在當時的影迷間引起熱烈討論，也被視為劇場版中極具代表性的名場面之一。

另一方面，史拉格作為反派的設定也別具新意。他不僅是少見以那美剋星人身份登場的劇場版BOSS，還揭示出其自出生以來便對七龍珠懷有特殊記憶，賦予角色一種宿命般的連結。這樣的背景使他與悟空一行人的對抗更具戲劇性，也打破過往反派多為單純強敵的公式。

不過，本作的缺點也相當明顯。由於片長僅有52分鐘，劇情進展相對急促，角色心理描寫與戰鬥鋪陳稍顯不足，多數場景以動作與對戰堆疊張力。部分評論認為，史拉格的形象雖新鮮，但其動機仍停留在「爭奪七龍珠、追求力量」的傳統反派模式，未能完全突破。

總體而言，這雖不是系列中票房最亮眼的作品，但憑藉史拉格這位獨特的反派，以及悟空「準超級賽亞人」的經典爆發場景，依然在影迷心中留下深刻印象。既延續90年代初《七龍珠》劇場版的熱潮，也為之後正式登場的超級賽亞人篇章，埋下重要的鋪墊與氛圍。

Dragon Ball Z: Super Saiyan Son Goku (Japanese: ドラゴンボールZ 超サイヤ人だ孫悟空, English: Dragon Ball Z: Super Saiyan Son Goku) is the seventh theatrical film in the Dragon Ball series, released on March 9, 1991. Produced by Toei Animation, the film runs for 52 minutes and grossed approximately 250 million yen at the box office. Centering on the brand-new antagonist Slug, the story is closely tied to the concept of the Super Saiyan. Although Goku does not undergo the canonical Super Saiyan transformation in the film, the golden aura he emits during his explosive power-up became an iconic early representation of the form, leaving a lasting impression on fans as a “prototype Super Saiyan.”

The story begins with an unknown celestial body approaching Earth, radiating a powerful evil presence. Soon after, an alien calling himself the “Galactic Overlord” Slug appears, intent on seizing control of the planet. His forces successfully invade and shroud Earth in a black mist, draining the planet of vitality. Despite the valiant efforts of Goku, Piccolo, Krillin, Gohan, and the other Z Fighters, Slug’s schemes continue to advance unchecked. As the battle escalates, Slug uses the Dragon Balls to wish for restored youth and strength, regaining his prime physical form. With his newfound power, he overwhelms the Z Fighters and drives them into a desperate struggle.

At the brink of defeat, Goku’s fury triggers a sudden awakening. His body radiates a blinding golden light, projecting an overwhelming aura that, while not a true transformation, carries the unmistakable essence of the Super Saiyan legend. The surge of power forces Slug to reveal his true identity—a towering, imposing Namekian. Empowered by this newfound strength, Goku turns the tide of battle and ultimately crushes Slug’s ambitions, saving Earth from annihilation.

From a critical and market perspective, the film’s highlight lies in its “foreshadowing of the Super Saiyan.” Though Goku’s transformation here is incomplete, the aura, the dramatic surge in power, and the golden glow all created a palpable sense that the legendary warrior was about to emerge. This moment sparked heated discussions among audiences and became one of the most memorable scenes in the early Dragon Ball Z films.

Slug also stood out as a unique villain. As one of the rare theatrical antagonists depicted as a Namekian, his backstory—hinting at a lifelong connection with the Dragon Balls—gave him a fateful link to the series’ lore. This added depth to his role as an adversary and differentiated him from the more formulaic “powerful invader” archetypes of previous films.

Nevertheless, the film’s weaknesses were also apparent. With a relatively short runtime of only 52 minutes, the pacing felt rushed, with limited character development and a heavy reliance on battle sequences to drive the plot. While Slug’s design and concept were fresh, his motivations still fell back on the conventional tropes of seeking the Dragon Balls and pursuing power, which some critics found underwhelming.

Overall, while Dragon Ball Z: Super Saiyan Son Goku was not among the franchise’s highest-grossing entries, it left a distinct mark thanks to Slug’s originality as a villain and Goku’s iconic “pseudo-Super Saiyan” transformation scene. It successfully carried forward the early 1990s momentum of the Dragon Ball Z films while laying thematic and visual groundwork for the eventual full debut of the Super Saiyan saga.
