The AntAgonizer

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.

Background
Tanya Christoff was born in 2250 and is 27 when James leaves Vault 101. As a child, she traveled the wasteland with her caravaner parents and she was a fan of the old Hubris Comics magazines that she found across the wastes, particularly Grognak the Barbarian comics.

At some point during her teens, her parents' caravan was attacked by giant ants and both her parents were killed. Witnessing this traumatized Tanya and led her to lose herself in the world of Grognak's stories, becoming obsessed with the character the AntAgonizer, a villain with a life story similar to hers. Eventually, she took on the mantle of the AntAgonizer herself and, after developing a method to tame giant ants, she sought out to carry out her comic book counterpart's goal of destroying mankind.

As the AntAgonizer, Tanya 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, harassing the town ever since.

Quests

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

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 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 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.

Appearances
Tanya Christoff/the AntAgonizer appears in Fallout 3, and is mentioned in "Grognak & the Ruby Ruins" in Fallout 4.

Behind the scenes
"AntAgonizer" is a play on words. As well as having the word "ant" in it, to "antagonize" is cause someone to become hostile.

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.
