Homestuck is a webcomic written, illustrated, and animated by Andrew Hussie as part of MS Paint Adventures (MSPA). The webcomic centers on a group of teenagers who unwittingly bring about the end of the world through the installation of a beta copy of an upcoming computer game. Homestuck features a complex story and a large cast of characters, starring the four children John Egbert, Rose Lalonde, Dave Strider and Jade Harley. Hussie invented an alien species, called trolls, that have a unique culture. Homestuck characters were particularly popular to cosplay at anime conventions during the early 2010s.
