~ Dr. Xenon's introduction in Nightmare Xmas. |
Dr. Xenon is the main antagonist of the 2023 Roblox game Tower Defense X.
She is a scientist who is responsible for sending enemies to raid the Commander's base and built the Eradicators, the Apex Predator and Exo Santa. She also formerly had a companion known as "Dr. Malory", who is presumably deceased or was used as a sacrifice to summon Calamity, the leader of Hell.
She is voiced by Robin van der Niet.
Appearance[]
Dr. Xenon is a human with light pink skin and silver hair. She dons a white lab coat with pink accents on top. Underneath the lab coat, she wears a black suit and tie. She also wears a headset with a red "X" floating above it. She sports black pants with pink stripes and black gloves. She has heterochromia iridum, a genetic condition which causes the irises to have different coloration, with her left eye being blue and her right eye being pink.
Personality[]
Dr. Xenon is shown to be arrogant, as seen in the 2023 Xmas event where she expects the player to be defeated by her forces and mentions that her simulations have shown "better results". She is also opportunistic, as shown by how she often forms alliances with the main antagonists of most events. Despite this, she is also implied to be remorseful over sacrificing Dr. Malory to summon Calamity as shown in a picture titled "flaw".
Biography[]
Base Game[]
While Dr. Xenon doesn't physically appear in the four main difficulties or Endless mode, she is mentioned by the Advisor twice during Endless, first when he discovers that the enemies are forces from the Plague Division of Dr. Xenon's Army, and later when Eradicator MK I C is defeated, commenting that Dr. Xenon isn't so great with the Eradicator's core overheating problem.
Xmas 2023[]
Dr. Xenon made her first physical appearance as the narrator of Nightmare difficulty in the 2023 Xmas event, replacing the Advisor. Here, she reveals that she is responsible for creating the Eradicators fought before in the base game difficulties, and hints at the return of Eradicator MK I, which would later become true when Endless mode was released. Near the end of Nightmare Xmas, Dr. Xenon reveals her goal is to take over the GDA (Global Defense Army), the main protagonists of the game. She is not seen again after this, as Exo Santa is defeated and the mode ends.
Tower Battles Crossover[]
In the Tower Battles x Tower Defense X event, on Normal difficulty, the Commander mentions that Dr. Xenon warned the GDA about the enemies in Void's army, implying that she may have worked for the GDA in the past. However, on Nightmare difficulty, Void mentions that he "already spoke to her", implying that Dr. Xenon is conspiring with Void.
Halloween 2024[]
In the 2024 Halloween event, despite not making a physical appearance, the Awakened frequently mention her, most notably the Engineer mentions that he "borrowed" her technology to use against the GDA. Furthermore, Chapter 2 of the event takes place in Factorium, an abandoned factory implied to be created by Dr. Xenon.

Trivia[]
- Despite being confirmed to be the main antagonist of Tower Defense X and play a major role in the game's lore, they never physically appear in the base game difficulties aside from being mentioned by the Advisor during Endless and have not appeared as a boss fight (however it is possible this could change in the upcoming Nightmare difficulty or in a future event).
