Creator / Toby Fox

Go To
Robert F. "Toby" Fox (born October 11, 1991) is the creator of Undertale and Deltarune. He also produces music, primarily for the Homestuck music team, published on the label What Pumpkin.

Previously known professionally as "Radiation", Fox began as an amateur musician and ROM-hacker, producing EarthBound: The Halloween Hack. This garnered him some attention for the quality of the music, and after he produced some fan pieces based on work done for Homestuck, Andrew Hussie quickly brought him onto the team. After joining the music team, he more or less became the leader of the music team (at least to the fans) and was both very prolific with his own work and helped with mastering and whatnot.

However, as time ground on, Fox began to seriously push forward his own work, first in the background, and then in 2013 in public via a Kickstarter: a game in the rough JRPG mold, written, directed and scored by him, called Undertale — The Friendly RPG Where Nobody Has To Die.

It certainly was that. It also became his defining work and, without exaggeration, one of the most artistically-influential and important video games of The New '10s. Undertale made Fox a comparative household name (somewhat to his embarrassment) and is now, by far, the thing he is best known for, wholly eclipsing his Homestuck work. He went on to support Undertale in a number of ways, including commissioning a Japanese translation after the game proved shockingly popular in Japan and supporting a number of Undertale side and fan projects.


In 2018, however, he was ready to release something more — something that had existed alongside Undertale the entire time. October 31st saw the release of "Chapter 1" of Deltarune, an episodic "sister game"/"parallel story" to Undertale; nearly three years later, "Chapter 2" was released. While Deltarune features many of the same characters as Undertale, Fox has stated that it is not meant to be set in the same "world" as its predecessor. Once again though, it prominently features Fox's music.

Toby Fox and his works provide examples of:

  • Author Avatar: The Annoying Dog, a small, white dog who appears in Undertale and Deltarune that has some kind of omnipotent force. After all, guess what "Dog" spelled backward is.
  • Creator Thumbprint: His distinct dramedy storytelling that mixes irreverent humor and psychological drama and his prominent use of leitmotifs. The Undertale and Deltarune soundtracks in particular connect nearly every song to one another through shared passages and samples, with the practice even extending to songs for completely unrelated works.
  • Pen Name: His real name is Robert Fox, but he is known online as Toby, formerly Radiation (briefly combining the two as Toby "Radiation" Fox).
  • Reclusive Artist: While plenty of photos and videos exist of him before then, Fox elected to stop showing his face for any public appearances/events after the release and surprise popularity of Undertale, first taking a photo of himself in a cardboard Ice-E mask as a default image for online sources before settling on various depictions of the Annoying Dog. What's more, outside a couple of appearances in Annoying Dog costumes (one at an award show, the other in the trailer for the Nintendo Switch port of Deltarune's second chapter), he avoids showing up physically at all.
