So at last you have penetrated the Court of the AntAgonizer, Queen of all Ants!
Tanya Christoff AKA the AntAgonizer is a "supervillainess" 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, comically emulating a supervillainess.
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. She cites their instinctual willingness to work together to accomplish goals, unlike humans' desire to kill one another through warfare. 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. 
A terminal in Hubris Comics contains a letter to the editor mentioning the AntAgonizer as one of Grognak the Barbarian's villains. The letter expresses disappointment saying the villain "never developed fully". The AntAgonizer's background story matches the comic book and she was to appear in Grognak and the Ants of Agony, but the comic was thrown out due to bad writing.
 Interactions with the player character
 Interactions overview
 Effects of player actions
- Wrath of the AntAgonizer: If you side with the AntAgonizer during "The Superhuman Gambit", there is a random encounter later on in which you find the AntAgonizer and a group of her ants attacking a group of wastelanders. The AntAgonizer is neutral towards you, but will turn hostile if you attack her ants.
- You can convince her to stop harassing the town without passing the speech check. If you tell her that you know where she got the inspiration for her AntAgonizer identity, and you convince her that there may be a second chance for her, she will give you the AntAgonizer costume and leave. You will receive karma. If you manage to convince the AntAgonizer to give up her superhuman identity, she may be seen wandering the Wasteland near Megaton without her AntAgonizer costume.
- Talking to Joe Porter reveals that her name is Tanya Christoff. He also offers insight into her (apparent) madness.
- It seems that AntAgonizer may have gone too far on her "future is for the ants, not for the human beings" philosophy, as she usually has a human flesh in her inventory instead of more common consumable items (discovered when viewing her inventory items via console).
- If you help the Antagonizer during this quest, she can be found wandering the wasteland with her ants in a random encounter, allowing you to obtain both costumes if you kill her upon this meeting. Alternatively, kill all the ants in the AntAgonizers lair, then visit the Robot Repair center. Convince the Mechanist that he is being a worse problem than the AntAgonizer ever was alone, then go back to the AntAgonizers lair. She will still be sitting on her "throne".
- You can obtain her costume through speech with the Lady Killer perk.
- It is possible to get 3 copies of her costume via exploits/glitches, look at Fallout 3 bugs for instructions on how to do this.
- You can simply kill her the first time you meet her when she is fighting the Mechanist in the street, you will get 400 caps from the mayor.
- The AntAgonizer will reward you with her unique knife, the Ant's Sting, if you kill or convince the Mechanist to give up and bring her his costume.
- If you do not wish to 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. You will have to hop on some rocks to get there, but this route takes you straight to the throne room where you can quickly get the quest done.
- Also, by way of the back entrance if you have not gone into Canterbury Commons yet, you can place mines around her throne which will detonate instantly when you return to talk to her after the confrontation in town. This will save a small amount of time fighting her.
Tanya Christoff, The AntAgonizer only appears in Fallout 3.
 Behind the scenes
- In the Polish version of the game, she is called "Entomologia" (Entomology) as a reference to Entomologia Motylkowska, a character in comic books by Tadeusz Baranowski.
- 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.
- It is possible for her to be invincible in the stand off between her and the Mechanist. This can even continue on into her lair if you choose to fight her. This can be fixed by loading a previous save or by targeting her with a high power weapon (like a missile launcher or Nuka-grenade) in V.A.T.S. Which should kill her instantly.
