Did Toby Fox Say What Frisk's Gender IS
Many people have claimed that Toby Fox has outright said that Frisk's gender is up to interpretation. But this seems to be an claim the community has spread through word of mouth and with no actual origin point to where the claim came from. If anyone can provide and actual source that would be useful.
This is a fairly common thing that happens with creators, people will claim they have said something they either never said, or something that is heavily misinterpreted. Like with Miyamoto, Sakurai, and Cawthon to name a few. Or if a creator does actually say something they fail to provide an actual source like with claims about the Sonic canon that Ian Flynn has apparently said.
So the only thing I could find on this topic apparently is a Toby Fox interview from The Existential Gamer. The Existential Gamer asked Toby the following "The protagonist in UNDERTALE is of ambiguous gender. This is also true of many of the monsters he/she encounters along the way. Was this a design choice, and what role does androgyny play in your vision of the world?" Toby chose to skip answering this. This is the only thing I could find and it appears Toby Fox just chooses not to answer the question at all.
So by technicality it is is up to player's interpretation, but that is because Toby just refuses to answer the question from the looks of things.
