Joel Varg Jarvison, also known by a wide range of aliases including Vargskelethor, is a Swedish livestreamer and content creator. He is the second-most prominent member of the Vinesauce streaming group, following founder Vinny. Based in Umeå, Sweden, Joel is known for his surreal humour, unique commentary style, and a variety of themed livestreams that blend absurdity with technical experimentation.

One of his most recognised series is "Windows Destruction", in which he sets up a virtual machine running various versions of the Windows operating system and deliberately infects it with malware until it becomes non-functional. This concept, though humorous in presentation, explores the limits and vulnerabilities of legacy software systems, and has posed technical challenges when attempted on Mac emulations.

In addition to his streams, Joel is noted for his interest in death metal, MIDI-based music, and a recurring fascination with skeletons and anime aimed at male audiences, often referred to as "Manime". Notable influences include series such as "Fist of the North Star" and "JoJo's Bizarre Adventure". His content often draws from his own unusual personal anecdotes and is marked by a distinct blend of chaotic energy and improvisational comedy. Read more on Last.fm.
