Big cap, Goku is the very definition of the chosen one. My man magically appeared in a god's dream, befriended another god, learnt UI on the fly, trained to be an angel and even in another noncanon scene, my boy became one with Shenron cos the animators knew everything revolves around Goku. He gets chosen to protect the world every damn time.
"Gon was always considered to be two steps below the actual special guy who is Killua" So basically Naruto & Sasuke
