History
Fox originally started out as a forum member at the EarthBound fansite, Starmen.Net, under the alias "Radiation" where he managed the website's PK Hack forum up until 2011. He first entered the public eye with his infamous "EarthBound Halloween Hack", also known as "Press the B Button, Stupid!", which was a submission for Starmen.Net's 2008 Halloween Funfest.

Fox also produced music for the webcomic Homestuck, after which he would go on to create Undertale which was partially developed in Andrew Hussie's basement.

Trivia

 * Toby Fox has visited this wiki's Dog Residue article and commented on a piece of vandalism on Papyrus claiming that the character was inspired by Octopimp.
 * Toby Fox is embarrassed by his Halloween Hack and has dubbed it "bad ROM hack with swears".
 * Although Toby Fox's official website's content was replaced with a link to the UNDERTALE website, a part of it with music composed by Toby still exists. For some reason, the name "musics" in the URL is misspelled "msuics".
