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, a companion piece of some sort to Undertale. Deltarune will apparently continue the Undertale story, and once again features his music.
His Creator Thumbprint is his signature composition "Megalovania", which appears across his three most famous projects (particularly the last of the three — the Undertale version has received the greatest amount of attention on the internet). The theme also plays in another EarthBound fan game (which he did not work on) known as Cognitive Dissonance. Toby Fox also came up with a new remix of the iconic Undertale track for Super Smash Bros. Ultimate DLC, which features elements from prior iterations of the song, along with references to other Undertale leitmotifs that those listening attentively may be able to hear.
