Appearance

Goku wears an orange martial-arts gi and is usually seen with an open, energetic grin. After wishing on Porunga, he regains his brown Saiyan tail. 32 38

• Brown Saiyan tail, restored through the Namekian Dragon Balls. 38
• Uses the Super Saiyan 3 form, whose duration is improved by the restored tail. 36
• Can transform into Super Saiyan 4 after his Time Chamber training. 42

Personality

Goku is intensely motivated by martial arts and the chance to face powerful opponents. Learning that an unfamiliar Saiyan had transformed on Earth immediately makes him want to return and spar, and Tarble’s Super Saiyan 4 power excites him rather than discouraging him. 18 32

He is candid, trusting, and often oblivious to social cues or danger. His blunt comments offend Tarble, Krillin, and the Namekians without malicious intent; he also initially fails to share Tarble and Vegeta’s suspicion of He Yi. 37 38 45 His impulsiveness can undermine plans, as he forgets to hide his strength while attempting to open the Silver Box. 47 48

Despite his rivalry with Vegeta, Goku readily acknowledges when Tarble has surpassed him and focuses on improving himself. 32 34

Abilities & Skills

Saiyan Transformations

Goku had already attained Super Saiyan 3 before meeting Tarble. He had spent a long time seeking a way beyond it, but had not identified the importance of his missing tail. 34 36

• His restored tail allows him to maintain Super Saiyan 3 for several hours after training. 36
• He regrows the tail through Porunga’s wish on New Namek. 38
• He reaches Super Saiyan 4 during the second Hyperbolic Time Chamber session. 42
• Super Saiyan 4 requires a base combat power above roughly 800 billion for a chance of success. 41 42

Ki Sensing and Power Release

Goku can sense exceptional ki across vast distances, including Tarble’s first Super Saiyan transformation while training on North Kai Planet. 17

• His measured base combat power is 300 billion when he enters the Hyperbolic Time Chamber with Tarble, Vegeta, and Rix. 40
• He can release his full base aura, though doing so exposes his true strength to observers such as He Yi. 47 48
• By the end of the chamber training, his base combat power reaches approximately 2.7 trillion. 42

Dimensional Channel Creation

Goku can break the Hyperbolic Time Chamber’s dimensional barrier through a ki-amplified roar, creating a channel back to Kami’s Lookout. 42

• The feat is performed in Super Saiyan Full Power form. 42
• Tarble, Vegeta, and Rix follow him through the channel. 42

Relationships
