Final Boss



The final boss, sometimes called Baphomet because of the introductory story in The Plutonia Experiment in the Final Doom manual, or the Icon of Sin because of the Doom II level it forms part of, is the final boss of Doom II, in MAP30: Icon of Sin. In TNT: Evilution it is simply called the "demon-spitter". In Plutonia it serves as the "Gatekeeper". See this walkthrough for a gameplay description of the boss in its original level.

All the other monsters are a single Doom thing, but the final boss is made up of a number of parts:
 * Romero's head is the thing that must be destroyed. It starts with 250 hit points, but it is hard to hit due to its location deep in a hole.
 * A Spawn shooter in front of the head launches skull cubes. This is reminiscent of how Satan gives birth to his daughter Sin in John Milton's Paradise Lost in that she is born out of his head (a parthenogenesis originally based on Zeus and his own daughter, Athena).
 * Several Spawn spots are located around the map. These are where the skull cubes land and spawn a monster.
 * Wall textures ZZZFACE1 through ZZZFACE9 are arranged to construct a demon face with a hole into its brain. This is what the player sees as the boss, but it has little to do with its functioning.

Trivia
Reversed, the DSBOSSIT is a distorted John Romero saying "To win the game you must kill me, John Romero".

The launch sound of the skull cube (DSBOSPIT) comes from Sound Ideas' General series sound library: Disc 6015, track 28-1: "Fire,Ball - Impact and large fire burst, rumble." It is a very widely used sound effect that has also been used in several movies (for example, Dragonheart and Underworld), television series (for example, ReBoot and Xena: Warrior Princess) and documentaries (for example Hawking's Paradox).
