Toby "Radiation" Fox is the creator of ''{{VideoGame/Undertale}}''. He also produces music, primarily for the ''Webcomic/{{Homestuck}}'' music team, published on the label What Pumpkin.

Radiation began as a fan musician, posting music not connected with the official team. After joining the music team sometime after ''Homestuck''[='=]s start, he has since more or less become the leader of the music team (at least to the fans) and is both very prolific with his own work and provides mastering work.

He has also has created a completely insane Halloween-themed ''VideoGame/EarthBound'' hack [[ExactlyWhatItSaysOnTheTin known as]] ''VideoGame/TheHalloweenHack''. You can find out more about it [[http://earthboundcentral.com/2009/10/earthbound-halloween-hack/ here]] as well as download it. He developed and released an independently-created non-standard [[EasternRPG RPG]] named ''VideoGame/{{Undertale}}'', which has arguably become even more notable and famous than his ''Homestuck'' work. You can download the free demo or buy the full game and/or soundtrack [[http://undertale.com/ here]].

His CreatorThumbprint is the composition "Megalovania", which appears across his [[VideoGame/TheHalloweenHack three]] [[Webcomic/{{Homestuck}} most]] [[VideoGame/{{Undertale}} famous]] projects (particularly the last of the three - the ''Undertale'' version has received the greatest amount of [[MemeticMutation attention on the internet]]). The theme also plays in another ''[=EarthBound=]'' fan game (which he did not work on) known as ''VideoGame/CognitiveDissonance''.

His non-''Homestuck'' work:
* ''The Baby Is You'' (link currently unavailable): Warning, as this is a [[ProtestSong Protest Album]] (about a FlameWar on the MSPA Forums), the content is incredibly crude and potentially insulting.
* ''[[http://sleepytimejesse.bandcamp.com/album/i-miss-you-earthbound-2012 Earthbound 2012 - I Miss You]]''
* ''[[http://tobyfox.bandcamp.com/ Undertale OST]]''
