Dragon ball Z is one of my fav. cartoon . The main character is goku . He born for protect the earth. In the beginning of the series, as a 12 year old, Goku is rather short, and his appearance can actually trick his age, with some considering him to be much less than 10 years old, and get rather surprised when they hear his actual age. During the next few years, Goku did not present many physical changes, other than his muscles becoming more pronounced. It wasn't until his first growth spurt between the age of 15 and 18 that he became almost indistinguishable from before, and was only recognized by his naive personality and "trademark" hairstyle. He had grown quite taller than most of his friends, with a well-built physique, with Bulma even calling him "handsome". Years later, between the ages 25-30 (seemingly after his first battle against Frieza), Goku seemingly had another growth spurt, and became slightly more taller, and much more muscular, finally reaching his physical prime, and the appearance essentially remaining the same from there on.
