ISIS

ISIS, or the Islamic State of Iraq and al-Sham, is the name of a terrorist organization and unrecognized state, known for being militant and religious extremists. The group appeared in the Season Eighteen episode, "Go Fund Yourself", where they show support for Eric Cartman's start-up company, the Washington Redskins, much to the unease of Kyle Broflovski. ISIS later withdraws support for the Washington Redskins, after witnessing Dan Snyder brutalized by the Dallas Cowboys, and boycotts the company.

Appearance
The members of ISIS appear wearing all black clothes, covering their bodies and faces, as well as military gear. They also carry black ISIS flags.
