Frola Gegen was the daughter of renowned Voth scientist Forra Gegen. Her father's assistant, Tova Veer, wished to pursue her romantically, and while neither mentioned it to Forra, he was able to tell. She said mathematics was not one of her father's strong suits and that his genius was in paleontology.
When Forra's Distant Origin Theory conflicted with Voth Doctrine, Frola urged him not to pursue the matter. As much as she loved her father, she found it incredible that he claimed Voth were related to a mammalian species such as Humans. (VOY: "Distant Origin")
Frola Gegen was played by actress Nina Minton.
