Franke Athens (age 10) is a camper at Whispering Rock Psychic Summer Camp. She can always be found near her best friend Kitty Bubai, but merely imitates her behavior and is not very witty on her own. Looking at their campster profiles, it is discovered that Vernon has a crush on her, but her feelings for him seem to be ambivalent at best. There's hints that she may be into girls.
Franke is voiced by Jessica Di Cicco.
Right after Basic Braining, Razputin meets Kitty and Franke for the first time. They ask for one of his arrowheads as a fee for letting him through to the main campgrounds, explaining the concept and origins of the currency in the process. They then leave peacefully.
The girls spend most of the rest of the day on the terrace near the Main Lodge, telekinetically making friendship bracelets for each other (or at least, certainly not for Raz). However, after Levitation training, both Franke and Kitty are sitting alongside Dogen in the TV room with their brains removed. Vernon keeps them company, telling a story about the Civil War.
After being rebrained, Franke and Kitty choose to sit in their cabin, tending to their fingernails instead of making themselves useful in any way.
