Tanya Christoff

Tanya Christoff AKA the "AntAgonizer" is a "supervillainess" located in the town of Canterbury Commons in Fallout 3. She possesses control over giant ants and is fighting her nemesis, the Mechanist. She is dressed in an ant costume, comically emulating a supervillainess.

Background
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.

Quests

 * The Superhuman Gambit: Uncle Roe offers a quest to stop the AntAgonizer's battle with the Mechanist.

Effects of player 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 you 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 you attack her ants.
 * The Lone Wanderer can convince her to stop harassing the town without passing the speech check. If the Lone Wanderer tells her that they know where she got the inspiration for her AntAgonizer identity, and the Lone Wanderer convinces her that there may be a second chance for her, she will give the Lone Wanderer the AntAgonizer costume and leave. The Lone Wanderer will receive karma. If the Lone Wanderer manages to convince the AntAgonizer to give up her superhuman identity, she may be seen wandering the Wasteland near Megaton without her AntAgonizer costume.

Appearances
Tanya Christoff, The AntAgonizer appears only 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.

Bugs

 * 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.
