DBZ Facts

•  Piccolo is actually only four years older than Gohan. Namekians grow and age much faster thanHumans or Saiyans, seeing as how Piccolo was already nearly full-grown by the age of 3.

• The Saiyans and the Tuffles waged a 10 year war for Planet Plant known as the Saiyan-Tuffle war.

•  Vegeta would technically be the "King" of all Saiyans instead of the "Prince" because his father was killed by Frieza, thus making him the rightful heir to the throne. However, he most likely does not call himself King out of respect for his fallen father.
• Broly, the Legendary Super Saiyan was born with a power level of 10,000. This is comparable to most Saiyan elite warriors!

• Goku is terribly afraid of needles.
