Pan

Pan is a tomboyishly young girl from the Dragonball franchise. She is a minor character introduced in the end of Dragon Ball Z and the main deuteragonist of Dragon Ball GT.

She is the daughter of Gohan and Videl, who married sometime after the Majin Buu Saga. She is the granddaughter of DB's ultimate hero Goku, his wife Chi-Chi, and the good-hearted yet greedy goofball glory-hound Mister Satan. She is the niece of Goten, though she tends to treat him more as a big brother. She regards the family of Bulma and Vegeta as family as well, and may sport a crush on Trunks. Her name derives from two traditions : Goku's family naming system, based on foods, and Videl's, based on mythological and religious tricksters. Like with Goten and Trunks and Bulla, it is unknown if she was born with a tail.

While her power level is formidable and should never be underestimated, she is also never shown to become a Super Saiyan. Akira Toriyama has said he struggled with what she would look like in that form, while fan speculation has placed Gohan's 'Mystic Saiyan' mode, which involved SSJ-like power without the physical transformation, as the cause for this. However, only a brief portion of her life is ever depicted in the series, and since her own descendants had this power, it remains possible she developed it later on.

One day while Mr Satan is visiting Gohan's house to see Pan. When he returns from his science conference, he changes to his Great Saiyaman person and spars with Mr. Satan, while holding Pan.

 * However Android 18 was the tritagonist of the Super 17 saga and Bulma (under Baby's control) was the secondary antagonist of the Baby saga while Bulma is the secondary tritagonist in the Shadow Dragon saga.
 * Pan is one of the few female characters that Master Roshi doesn't try to flirt with, most likely cause Pan is only a little girl.
