Official description: The True Pacifist flavor of Frisk. Although she is female in this universe, she rarely enjoys discussing her past or her identity, and both continue to remain a mystery. The only thing she will generically admit to is having been bullied extensively as a child, although there are occasional hints of something far darker than that. 

Even so, Frisk maintains her general friskiness. She’s playful, mischievous, friendly, flirty, and endlessly forgiving, all while keeping her inherent hot blood and general sass under check – mostly, anyway. Frisk believes in the default good of absolutely everyone and that fate can always be changed – sometimes to absurdly stubborn, literally self-destructive ends. 

Having absolute control over the timeline has turned Frisk into something of a control freak. She feels it is her duty to use her powers to ensure peace and prosperity in the world – and more and more, it’s becoming harder for her to relinquish that.
