Hahaha! Bow, peasant! Bow before the Ant Queen!

The AntAgonizer, real name Tanya Christoff, is a "supervillain" located in the town of Canterbury Commons in 2277. She possesses control over giant ants and is fighting her nemesis, the Mechanist. She is dressed in an ant costume, emulating a supervillain.


In the past, Tanya read comics about supervillains. Her parents worked as caravan drivers.

Once her family succumbed to a giant ant attack, this gave her the idea of taking on the guise as "AntAgonizer", named after the villain from the Grognak the Barbarian comics. The identity made her more commanding, thinking of herself as something greater than ants, which she used to attack settlements. She has been harassing Canterbury Commons because she thinks the town is a blight on the wasteland.[Non-game 1]

She has a fierce rivalry with the Mechanist, and would do much to see his downfall. Despite the comic describing Grognak the Barbarian playing a role in AntAgonizer's defeat, she doesn't wish to share that fate.

Effects of player's actions[]

  • Wrath of the AntAgonizer: If the Lone Wanderer sides with the AntAgonizer during "The Superhuman Gambit," there is a random encounter later on in which they find the AntAgonizer and a group of her ants attacking a group of wastelanders. The AntAgonizer is neutral towards the Lone Wanderer but will turn hostile if they attack her ants.
  • The Lone Wanderer can convince her to stop harassing the town without passing the Speech challenge. If she is told that the Lone Wanderer knows where she got the inspiration for her AntAgonizer identity, and convinces her that there may be a second chance for her, she will give up her costume and leave. The player character will gain Karma if they manage to convince the AntAgonizer to give up her superhuman identity. She may then be seen wandering the wasteland near Megaton without her AntAgonizer costume.



  • Talking to Joe Porter reveals that her name is Tanya Christoff.
  • Her costume can be obtained through speech with the Lady Killer perk.
  • The AntAgonizer will also give her unique knife, the Ant's Sting, as a reward if the Mechanist is either killed or convinced to give up and his costume brought to her.
  • If the idea is to not go through the cavern leading to the AntAgonizer, there is a locked sewer grate on the top of the hill leading to the back entrance. The Lone Wanderer will have to hop on some rocks to get there, but this route takes them straight to the throne room.
  • If the Lone Wanderer gets the Mechanist's costume by killing or convincing him to stop and confronts the AntAgonizer while wearing the Mechanist's costume, she will confront the Lone Wanderer as the Mechanist and say that "he finally came to their final battle." This will result in her attacking with a Ripper instead of the Ant's Sting and some soldier ants.
  • She may have human flesh in her inventory.


Tanya Christoff/the AntAgonizer appears in Fallout 3 and Fallout Shelter Online. The fictional character she models herself after is mentioned in Grognak & the Ruby Ruins in Fallout 4 and by the comic book expert in the Fallout 76 update Expeditions: The Pitt.


PCPC Xbox 360Xbox 360 Sometimes she can glitch and end up standing outside of Megaton, still dressed in her costume but unaccompanied by her ants. This bug can occur if The Superhuman Gambit was completed without visiting her. [verified]




  1. 1.0 1.1 Fallout 3 Official Game Guide Game of the Year Edition p.100: "The Antagonizer
    Born 27 years ago, Tanya's parents lived as caravan drivers, before they were killed by Ants, an event that made Tanya lose herself in the world of Hubris Comics's characters and befriend the insects that spared her life. Christoff thinks that Canterbury Commons—a major location in the trading route her parents helped put on the map—is a blight on the Wasteland. Locals used to see Christoff lurking in a sewer system to the north of town, covered in mud and dirt. Giant Ants eventually started hanging around. A few months ago, she disappeared and reappeared as the AntAgonizer and has been harassing the town ever since."
