Ryan Murphy has cast a lot of unexpected people over the years. Casting John Waters as a doctor who draws exactly 13 vials of blood and keeps live snakes in his medical bag might be the purest Murphy move of the entire franchise.
In the first two episodes of American Horror Story Season 13, Waters appears as Mr. Phibes, the personal physician of the mysterious Mr. Nas. He only has a few scenes, but they are already some of the most memorable images of the new season.

This picture is not posed. It's really like this to get Mr. Nas ready: 4 hours in the makeup chair, 4 people, 8 hands. Except on full-body bathtub days, then it was 6 people, 12 hands, 8 or 9 hours.

Who Is Mr. Phibes?
Mr. Phibes is the shady doctor who tends to Nas on the 13th floor of the Apollyon. Once a week he draws 13 vials of blood. He tells Ben the samples are for monitoring “biomarkers for age and disease.” He stores the vials in the same bag that contains living snakes. Constance treats the whole ritual as completely normal.
The name itself is a deliberate reference. Dr. Phibes is the title character from the classic 1970s horror films The Abominable Dr. Phibes and Dr. Phibes Rises Again, in which Vincent Price played a disfigured, revenge-driven doctor. Waters wearing the name is pure camp horror lineage.
The Snakes and the Blood
The snakes are the detail everyone is talking about. They are not metaphorical. They are living, moving reptiles sharing space with the blood vials. Ben notices them. Constance does not explain them. Phibes offers no further comment. In a season already obsessed with the number 13, the weekly extraction of exactly 13 vials feels less like medicine and more like ritual maintenance.
Whether the blood is being tested, consumed, or used for something far darker remains one of the open mysteries of the early episodes. What is clear is that Nas requires this process and that Phibes is the only person trusted to perform it.
Why John Waters Fits Perfectly
Waters has spent his entire career celebrating the grotesque, the outsider, and the proudly artificial. Putting him in a white coat inside a Ryan Murphy horror series feels inevitable in retrospect. He does not play the role for easy laughs. He plays it straight, which makes the snakes and the blood count even more unsettling.
His presence also expands the season’s already crowded roster of icons. Alongside Jessica Lange, Sarah Paulson, Evan Peters, and the returning monsters, Waters adds a different kind of cult energy — one that comes from outside the usual Hollywood actor pool.
How Phibes Connects to the Larger Story
Everything about Phibes points back to Mr. Nas. The blood draws, the snakes, the weekly schedule, and Constance’s complete acceptance of the process all suggest that Nas is not a normal patient and that Phibes is not a normal doctor. If Nas is the “ultimate evil” Murphy has teased, then Phibes is the caretaker who keeps that evil functional.
The character has only appeared briefly so far. Given how this season is structured, it is unlikely he stays on the margins. The snakes alone feel like a detail that will pay off later.
What Fans Are Watching For
Will Phibes appear again when the next batch of episodes drops on October 1? Will the snakes turn out to be more than set dressing? Is the blood actually being used to sustain Nas or to power something larger connected to the portal in the basement?
For now, Mr. Phibes is the season’s purest shot of classic gothic weirdness. A legendary filmmaker in a doctor’s coat, a bag full of snakes, and 13 vials of blood drawn on schedule. It is the kind of image that only American Horror Story would put in the middle of a mainstream cable drama — and only John Waters could make it look completely natural.

Why the Snakes Stick in Viewers’ Minds
Horror lives on images that are hard to explain. Live snakes in a medical bag next to 13 vials of blood is one of those images. John Waters does not overplay the moment. He treats it as routine. That calm is what makes the detail unnerving. Constance accepts it. Ben notices it. The audience cannot unsee it.
The Dr. Phibes name reference also rewards older horror fans. Vincent Price’s films mixed camp, revenge, and medical grotesque. Waters carrying that name into a Ryan Murphy series is a perfect overlap of cult traditions.
Phibes as Infrastructure for Evil
Not every villain needs a monologue. Sometimes the scariest supporting character is the professional who keeps the system running. Phibes draws the blood, stores the snakes, and leaves. If Nas is the engine, Phibes is the technician. Season 13 has already shown that patterned death feeds something on the 13th floor. The weekly ritual may be how that something stays stable between massacres.
Camp Horror Done Straight
John Waters built a career on celebrating outsiders and bad taste as art. Playing Mr. Phibes straight, without winking at the camera, is the smartest choice the role could make. The snakes and the blood count would collapse into parody if the performance begged for laughs. Instead the show lets the image do the work. That restraint is why the character is already one of the premiere’s most quoted details.
