Gohan was first a timid, shy child, until Goku and Piccolo trains him and he becomes less weak, and more brave. He almost destroyed Vegeta with the Super Saiyan tail/ the monkey when he sees a full moon, but Goku stopped him. He is also a Super Saiyan but it won't show until episode 80 or the next 2 episodes.
