Bill Cipher’s Brother the New Villain? 'Gravity Falls' Fans Think So
And the showrunners haven’t denied it. Suspicious, right?
Okay, Gravity Falls fans, I have to tell you about this wild theory that’s been buzzing around my brain like a hyperactive gnome. So — you know Bill Cipher, right?
The creepy triangle demon we all love to hate? Well, what if I told you he actually had a brother? Yep, a brother who’s possibly the villain for Season 3.
Enter Tad Strange — the "normal guy" who proudly wears the badge of "Being normal is my calling!" Honestly, in Gravity Falls, being normal is the most suspicious thing ever.

Like, really? In a town full of gnomes, ghosts, and weirdness, you expect me to buy that this guy is just your average Joe? No way.
Here’s the kicker: Ted’s voice is none other than Cecil Baldwin’s — the cult narrator from Welcome to Night Vale. If you don’t know who that is, just imagine spooky but chill vibes wrapped in a velvet voice.
Then, Alex Hirsch (in Bill’s own voice) drops this gem on Reddit: "Ted is a real square, and a square is the worst shape." Boom — fandom meltdown. Purple demon square fan art everywhere.

Sure, the show says Ted’s "just a regular bloke," but in this universe, "regular" is code for definitely hiding something shady. Plus, who else but a sandwich-loving, supposedly boring dude could secretly be plotting evil?
