The Dragon Ball franchise, created by Akira Toriyama, has captivated audiences around the world thanks to its dynamic characters and epic battles.
From the original series through Dragon Ball Z and Super , its protagonists have undergone significant transformations.
In this article, we analyze the evolution of some of the most iconic characters in the Dragon Ball universe.
Goku: from Saiyan to Super Saiyan God
Goku, the main protagonist, has lived one of the most extraordinary journeys in anime history.
He started out as an innocent boy with a monkey tail in Dragon Ball , and through tireless training and demanding battles, his evolution has been constant.

First steps
In the original series, he is portrayed as a young boy with immense strength and a pure heart. His early adventures include the search for the Dragon Balls and his apprenticeship as Master Roshi's disciple.
Transformations in Dragon Ball Z
At the beginning, Goku discovers his Saiyan lineage, which explains his extraordinary combat ability and the distinctive feature of his tail, as well as his ability to turn into a kind of "Giant Ape" under the full moon.
Later, the introduction of the Super Saiyan state marked a milestone in the anime, representing its ability to overcome impossible limits.
Divine powers
With Dragon Ball Super , Goku reached even higher levels, such as Super Saiyan God and Super Saiyan Blue.
Battling gods and other powerful entities, his career embodies the ideal of constant improvement.
Vegeta: From Rival to Redeemer
Vegeta, the proud Prince of the Saiyans, stars in one of the most complex developments in the franchise.
Introduced as a villain in Dragon Ball Z , his story arc becomes a story of redemption and personal growth.

A threatening arrival
His first appearance portrayed him as a ruthless antagonist, obsessed with immortality and surpassing Goku. This laid the groundwork for one of anime's most iconic rivalries.
Path to redemption
Throughout the sagas, Vegeta's character softened. His alliance with the Z Fighters and his bond with Bulma revealed his more human side. And although always a step behind Goku, he also had the opportunity to demonstrate his immense capabilities in battle, which increased with effort and hard training, proving that not everything revolved around natural talent: willpower and effort are equally important.
In Dragon Ball Super , he established himself as a true hero with his own principles.
Piccolo: From Demon King to Protector of the Earth
Piccolo's evolution is also one of the deepest and most symbolic narrative arcs within the Dragon Ball universe.
His transition from feared villain to respected hero and father figure represents a complex narrative of redemption, which has cemented him as one of the franchise's most well-rounded and beloved characters.

The original Piccolo
Introduced in the original series as the son and reincarnation of the Demon King Piccolo Daimaō, Piccolo was born with a clear goal: to avenge his father's defeat at the hands of Goku and conquer the world. His fights were intense, and his power was fearsome.
In contrast, we can also observe a lonely childhood, in which he seemed to long to know the concept of a family.
Mentor and protector
Throughout Dragon Ball Z , Piccolo undergoes a momentous change in character. His decision to train Gohan after Goku's death constitutes the most significant turning point in his redemption arc.
During this training, an unexpected emotional bond develops, transforming him into a true mentor and father figure to the son of his former enemy. Furthermore, Gohan's warmth and childlike innocence led him to experience feelings and emotions he had previously been unable to experience, raising the question of whether his nature was destined to be a villain by Piccolo Daimaō's will when he was initially born, or whether his environment, lacking a home, family, or friendship, led him to this. It is even suggested that, in his time spent with Gohan, he may have come to know Gohan even better than Goku did, in some aspects of his personality.
Wise, powerful and leader
In Dragon Ball Super , Piccolo maintains his role as a mentor, although now expanded to an interplanetary level. He remains essential as a technical, tactical, and emotional guide, assuming a key role as a mentor and defender of the Earth.
Bulma: The Brilliant Innovator
Bulma is a constant presence throughout the saga. Her intelligence and technological skills have been instrumental in the group's progress and the achievement of many of their self-imposed goals.

Talented adventurer
From the beginning of Dragon Ball , she has been portrayed as a brilliant scientist. Her ability to build everything from Dragon Ball detection radars to dimensional storage capsules quickly establishes her as a technical genius.
Key support in every confrontation
In Dragon Ball Z , Bulma expands her role as the mother of one of the warriors of the future and Vegeta's partner, offering an emotional counterbalance: rational, protective, and outspoken. Her active and determined personality directly influences Vegeta's emotional development.
Technological leader and diplomat
In Dragon Ball Super , she not only continues as an inventor, but leads projects on a planetary and galactic scale.
Her greatest technical achievement is the creation of a time machine, and her mastery of alien language and technology allows her to communicate with gods and higher entities. This establishes her as a determined, visionary woman with leadership abilities.
A legacy of transformation
The evolution of characters in Dragon Ball reflects universal themes such as personal growth, redemption, and overcoming.
From Goku's quest to become stronger to Vegeta's moral redemption and Piccolo's transformation, each journey adds depth to a universe that continues to capture generations.
As the franchise continues to expand with new sagas and challenges, the constant transformation of its protagonists remains the core of its charm.
For both veteran and new viewers, Dragon Ball offers a story that never ceases to inspire.
