Bill Cipher is the grinning, one-eyed triangle demon from Gravity Falls, and he’s basically chaos in a bow tie. First popping up in Alex Hirsch’s Disney XD series (2012–2016), Bill became a fandom obsession thanks to the show’s secret codes, creepy humor, and that “make a deal” villain energy. He’s a mashup of Illuminati jokes, cosmic horror, and meme fuel, which is why Bill Cipher art still hits so hard on Clothing. I design around Bill because he’s instantly recognizable and delightfully unhinged. Grab yours and summon some weirdness today!
