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, comically emulating a supervillain.
Tanya Christoff was born in 2250 and is 27. Tanya's parents made their living as caravan drivers before they were killed by ants, when Tanya was still a child. The event made Tanya lose herself in the world of Hubris Comics's characters and she came to befriend the insects that spared her life. Tanya Christoff, now known as the AntAgonizer 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. She disappeared for a few months 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.
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 player character, but will turn hostile if he/she attacks her ants.
The Lone Wanderer can convince her to stop harassing the town without passing the speech check. If the player character tell her that they know where she got the inspiration for her AntAgonizer identity, and convince her that there may be a second chance for her, she will give the player character 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. He also offers insight into her (apparent) madness.
If you help the Antagonizer during this quest, she can be found wandering the wasteland with her ants in a random encounter.
You can obtain her costume through speech with the Lady Killer perk.
It is possible to get an extra copy of her armor or an extra copy of her helmet via exploits/glitches. See Fallout 3 exploits for instructions.
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.
If you get the Mechanist's costume by killing or convincing him to stop and go confront the AntAgonizer using the Mechanist's costume, she will act like you are him and will say that "he finally came to their final battle" and will atack you with a Ripper instead of the Ant's Sting and some Soldier Ants.
xbox360 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]
