What The 'Z' In Dragon Ball Z Means (And Why It's So Important)
As a continuation of the "Dragon Ball" universe, "Dragon Ball Z" has the world's fate regularly fall into the clenched fists of heroic Z fighters like Goku and Vegeta. These heroes regularly live, die, and fight again whenever Earth is invaded or when a martial arts tournament needs organizing to dictate the future of the human race, but here's one that might still stump fans of the show to this day: what does the "Z" actually stand for?
Often mentioned by voice artist Kyle Henry Hebert during his narration at the start and end of every episode of the dubbed version of the show, the letter "Z" sure felt like it carried some weight. For the show's creator, Akira Toriyama, who at the time was hoping to wrap up the manga it was adapting from, the "Z" was a simple stamp to put an end to Goku's adventures.
In a translated interview from Kanzenshuu, Toriyama clarified, "'Z' is the last letter of the alphabet, right? Anyhow, from that time, I really already wanted to end the comic (laughs), so I gave the title a 'Z' with the meaning of 'That's all, folks.'" But while Toriyama hoped the "Z" would end things, it gained new life through means more powerful than any spirit bomb — the fans.
Dragon Ball Z fans gave a Saiyan ability the name of Zenkai
Much like most of the bad guys in "Dragon Ball Z," the tagged-on letter to the show gained a new form, and fans had their own theories on what it could mean. One idea was that the "Z" stands for "Zenkai," which is not only Japanese for "last time" but also what Goku uses to describe a specific Saiyan trait that he and his race possess in the "Dragon Ball" manga, Chapter 283, "Ginyu Steps In."
For fans, Zenkai became another label for Saiyan Power, which is unique to the warrior race. In the heat of battle, Saiyans have the power to recover quicker than their opponents, even to the point of gaining greater strength to win whatever planet-shaking scrap they find themselves in. This feature makes Goku and the other Saiyan Z fighters the best line of defense. The greater beating they receive, the faster they heal, and the quicker they are to adapt should they be hit with the same attack in the future.
Additionally, the word also appeared in the show's closing theme for the song "Detekoi Tobikiri ZENKAI Power!" for the first 199 episodes of the show, only fortifying the reasoning behind the added Z. Whether fans choose to add more meaning to the letter or not, one thing can't be denied; "Dragon Ball Z" still sounds cool after all these years.
