Mentor in Progress!

Pan is the Daughter of Gohan and Videl, Granddaughter of Hercule and Goku! That's one of the many reasons she's well known in this series. Another reason is the new WORLD CHAMPION of the Tenkaichi Budokai! After going under vigorous training under someone surprising , Pan has been known as one of the strongest warriors on Earth in this story. She has the brains and hidden potential of her father but can get cocky at times due to the lack of "strong opponents" (The cockiness is from Hercule, of course) and her goofiness and appetite is straight from Grandpa Goku! During the series, She'll take on Tenzo as her pupil for a time being as for she's always wants one! Well, one who dares to do so. 

For Pan, I'd imagine her to sound like Caitlin Glass (or like Videl to resemble her likenesses a bit)

Or try to see if you can try to do your own spin on her voice based on what she sounded like in GT (Try to sound older variation of that Pan voice!)
