go on to Piccolo              

The daughter of Gohan and Videl, Pan is probably the strongest female fighter. She is born about 7 years after the fight with Majin Buu, and at the age of three, competes in a Tenkaichi Budokai (which roughly translates to "The World's Greatest Martial Arts Competetition"). When Son Gokou, her grandfather, and Trunks are about to depart for outer space to look for the Black Star Dragon Balls, Pan sneaks aboard their space ship without them noticing. She just wanted a little adventure, but she wound up getting into a lot of trouble.
