The Bridge Worm will sometimes venture far from its nest if prey is hard to come by, instinctually hunting at night and in abandoned areas to avoid discovery. Photo below: The adolescent Bridge Worm folds back its false face as it prepares to feed.

The Bridge Worms are internet urban legend creatures that were created as part of the Trevor Henderson Mythos. As their name implies, the Bridge Worms tend to lair beneath bridges and other overpasses. They are known for using fake faces to lure their prey and then eat them when it was too late.


The known history of the Bridge Worms started off when a photo of a big creature inside of a tunnel under a bridge started spreading on the internet. In the photo, a large white creature with a sad face, laying on the ground, with its hands and its white face visible is physically seen. People started speculating on the creature, until a drawing of the creature started spreading on the internet, on which it is written "Bridge Worm", giving the creature its name. In the drawing, it is suggested that the Bridge Worm has a false face and that underneath its innocent-looking white face, hides its much more sinister real face (as shown in their infobox).

Further on, a photographer by the name Thomas Pearong has been missing for a while. Later on, his final photo was found. In the photo, the real face of the Bridge Worm is revealed to the public, which appears to be a fleshy-muscular sharp-toothed creature. The Bridge Worm ended up possibly consuming the photographer. Trevor said that the camera was found in a pile of acidic fecal matter which was intermingled with the remains of the photographer. Once the news broke, the question of what the Bridge Worm is started to spread.

People started describing the Bridge Worm as a hostile creature that acts like a spider, which is very dangerous. It would always be in the same location, waiting for its next victim. Once the victim arrives, the Bridge Worm would jump out from its location and instantly murder and consume the victim. Trevor has stated that the Bridge Worm will sometimes venture far from its nest if it cannot find prey and it will usually hunt at night and in abandoned places to avoid being discovered during its hunt.

Theories started spreading that the Bridge Worm will one day get out from its location and start finding victims at an alarming rate. It is also confirmed that the Bridge Worm photo taken by Pearcing shows a teenage version of the Worm, leading to the question of what the adult Bridge Worm is like. An old photo of one of the Giants jumping on a road is heavily implied to be the adult version of the Bridge Worm, though it does lack several features such as the arms and defined face seen in Trevor’s new illustration of an adult Bridge Worm. It is possible that Bridge Worms can grow in different ways, or that this giant may be a subspecies.

An artwork of the Bridge Worm with a larger, longer and buffer appearance and a more defined-looking face has been posted by Trevor on Twitter. He comments that the facial markings of the Worm’s false face become more defined to assist in hunting as they get older, confirming that the artwork is of an adult Bridge Worm. On Twitter, he has revealed several more details about the biology of the Bridge Worms. In earlier stages of their lifecycle, they can move from bridge to bridge, until they adhere. If they cannot find prey, many shrivel up most likely due to hunger, but some are strong enough to migrate someplace else. When it is a 3–4 foot long baby, its arms and false face aren’t developed yet. Younger Bridge Worms’ eyes can’t focus properly yet, as shown by the outward-facing pupils, though it doesn’t need sight to live off of passing prey due to its false face that lures them in. As it gets bigger and hungrier though, its eyes slowly become more developed, allowing it to stare at its prey as it devours them alive.





  • The Bridge Worms were created by Trevor Henderson, who is known for making various bizarre creatures over the internet. His other creations include Siren Head, Cartoon Cat, the Country Road Creature, the Man with the Upside-Down Face, the Smile Room, the Good Boy, the Lamb, the Man in the Red Room, the Fetid King, the Giants and Long Horse.
  • On Twitter, Trevor Henderson posted an artwork of the Bridge Worm with a larger, longer and buffer appearance, calling it the "patron saint of dark places, of hungry life, of spotless bones". On the same post, he comments that the false face's markings become more defined to assist the Bridge Worm in hunting as they get older with more exposure to people, suggesting that the artwork is of an adult Bridge Worm.
  • It is heavily implied that the Bridge Worms are connected to the Giants, as one of the Giants is heavily implied to be an adult Bridge Worm.
  • It is implied that the Man with the Upside-Down Face has appeared near events in which the Bridge Worms and possibly Cartoon Cat have killed people.
    • It could be possible that they all have some connection, though it is more likely that the Man is only there to feed off the negativity of the situation.
