As Goku grows up, he becomes the Earth's mightiest warrior and battles a wide variety of villains with the help of his friends and family, while also gaining new allies in the process.
The boy is initially full of violence and aggression due to his Saiyan nature, until an accidental head injury turns him into a cheerful, carefree person.
[13] Toei kept protraying Goku as heroic figure, especially in the anime sequel Dragon Ball GT where he often rescues his granddaughter Pan as producer Kōzō Morishita was influenced by the 1997 film Titanic.
There was only a single final draft of the character, although Nakatsuru did consider making the hair blonde, he ended up choosing black as it provides more contrast with the red fur.
Goku's first shown martial arts attack as a child is Jan ken[nb 35], three physical blows modeled after the hand signs in rock-paper-scissors.
After training with the Earth's Guardian, Kami, Goku learns to fly by virtue of the technique Bukū-jutsu[nb 38] and uses the Nimbus cloud less frequently for flight travel.
After becoming the runner-up champion of the 21st and 22nd tournaments, Goku wins in the 23rd with Piccolo's defeat, and marries Chi-Chi soon after to fulfill a promise he made to her years ago despite not knowing what marriage was.
[47] While Grandpa Gohan was taking care of him, Goku accidentally fell into a deep ravine and suffered a severe head injury, which caused him to forget his mission and drastically altered his personality.
Ten years later, during another World Martial Arts Tournament, Goku meets Uub, Buu's human reincarnation, and leaves with him, intending to train him as the new protector of Earth.
Bardock has a strong suspicion that Frieza is up to something when he receives an order on his scouter for all Saiyans to return home, so he convinces Gine to send their infant son in a space pod to Earth.
In the present, following the events of the Tournament of Power, Goku and Vegeta encounter another Saiyan survivor named Broly, whom Frieza has recruited to defeat them.
[57] In the manga, directly after the final scene of Broly, Goku and Vegeta meet Galactic Patrol by Jaco and a mysteriously highly skilled agent named Merus in order to help stop an ancient warlock called Moro.
With Moro headed to New Namek to use the Namekian Dragon Balls, the two Saiyans travel to the planet to stop him, where they are defeated by him using his magic to drain their life essences until near death.
Even after healing him with a Senzu bean, he is unfazed by his ensuing sneak attack, unsuccessfully attempting to convince him to reconsider his ways and go back to prison, and him using a stray severed arm with Merus's copied power to obtain Ultra Instinct for himself, Goku continuously outmatches Moro.
Ultimately, with the help of his friends and family, along with key assistance from Buu/Grand Supreme Kai and Uub unknowingly contributing divine power, Goku manages to finish off Moro and save the Earth once more.
Much later, Goku and Vegeta are contacted by a group of beings called the Heeters, on a seemingly imperative mission to defeat a surviving member of the now-extinct sharpshooting Cerealean race; Granolah.
Goku stalls him by teleporting across random locations within the cosmos via Shunkan Idō with Gas tailing him, in an effort to give Granolah time to regain his power.
Remembering Whis' advice about finding one's true and personal Ultra Instinct, Goku later molds his own version of the technique, using his emotions as freely as he pleases.
Frieza kills Gas and Elec, the Heeter leader and mastermind of the coup, in swift succession, before unveiling a new transformation and demonstrating his new powers by knocking Goku and Vegeta out of their empowered forms in one quick strike.
[61] Goku, Trunks and his own granddaughter Pan travel the universe to search for the Black Star Dragon Balls and return them to Earth to prevent its destruction.
For the release of the single of the Dragonball Evolution international theme song "Rule", Toriyama supplied CD artwork of singer Ayumi Hamasaki dressed as Goku.
[79] The collected tankōbon volume of Jaco features the bonus story Dragon Ball Minus: The Departure of the Fated Child, depicting how and why Goku's parents sent him to Earth.
[82] Weekly Shōnen Jump's Gag Special 2005 issue, released on November 12, 2004, featured a Bobobo-bo Bo-bobo one-shot Dragon Ball parody manga, a retelling of the first fight between Goku and Vegeta.
[89] On April 7, 2007, Goku and Fuji TV announcer Masaharu Miyake were commentators on the anime segment in the Japan Great Man Awards[nb 61] titled Who is the Strongest Hero?
[97] The episode "Goku vs. Superman" in the web series Epic Rap Battles of History[98] won a Streamy Award for Best Music Video.
[116] In his book about Akira Toriyama published in 2004, Julius Weideman said Goku's journey and ever-growing strength resulted in the character winning "the admiration of young boys everywhere.
"[127] In Mania Entertainment's 10 Most Iconic Anime Heroes, Thomas Zoth commented that "Goku and Dragon Ball completely revolutionized shōnen manga.
[153] Despite his predominantly positive reception, Goku has received some negative feedback, in particular for his characterization in Dragon Ball Super due to how his constant desires for fighting stronger enemies resulted in setting up a story where all universes could be destroyed.
[154] Monique Jones from Syfy panned the character's relationship dynamic with his wife, as well as his perceived incompetency and irresponsibility as a father, drawing attention to the "tons of memes and fan chatter about Piccolo actually being the best dad Gohan's ever had".
[161] Both Goku and Vegeta were criticized for being too overpowered in Super to the point they steal the series' spotlight to the supporting cast while their strategies either lack complexity or create a plothole such as the time limit to the fusion Vegito.
