Goku
Goku’s defining strength is not certainty that he will win. It is his eagerness to learn from the person in front of him.

From Son Goku to Saiyan survivor
Raised by Grandpa Gohan, Goku begins without social knowledge but with a clear sense of fairness. Training under Master Roshi teaches discipline and connects him to Krillin. Dragon Ball Z later reframes his unusual tail and strength: he is Kakarot, a Saiyan sent to Earth, yet his life there—not blood alone—forms his identity.
Rivals, family and teachers
Bulma opens the world to Goku; Krillin becomes his oldest peer; Piccolo and Vegeta transform from enemies into essential allies. His family complicates the freedom he associates with training. Gohan and Goten inherit his potential but not his exact desires.
A changing kind of hero
Goku often spares opponents because he sees future possibility and wants a better contest. That instinct creates allies, but it can also expose others to risk. His development is less a march toward conventional maturity than an ongoing negotiation between private passion and public responsibility.
Techniques and forms
The Kamehameha demonstrates his talent for learning; Kaio-ken makes bodily risk visible; the Spirit Bomb depends on energy freely given by others. Super Saiyan turns grief and anger into a threshold. See the guides to attacks and transformations.
