Icon of Sin

The Icon of Sin was the living demonic entity that led the demonic army that invaded earth in 2022, and it served as the main antagonist and final boss in DOOM II: Hell on Earth. It was killed by Doomguy, who returned to Hell to put a stop to the invasion.

Concept and Creation
In DOOM II: Hell on Earth, the Icon of Sin is not an actual monster NPC like all of the other demonic variants. Instead, id Software created wall textures serving as the Icon's face while the actual enemy NPC was hidden behind them. The NPC hidden inside the Icon has a sprite of a severed head resembling John Romero. As it is not the so-called average monster, it does not count as a monster kill once defeated.

The Icon of Sin is depicted as a giant goat-like demon head bio-mechanically mounted into a wall. It is rumored that it had a gigantic body behind that wall.

The modder for DOOM: Reawakened disliked the Icon of Sin and decided to not include one in the mod.

History
There is very little information about the Icon of Sin and its origins. What is known about it is that it was one of the most powerful beings of Hell and was responsible for the hellish monsters that attacked the Mars expedition and Earth. Most of the survivors of the First Demonic War would confuse the Icon as Satan given its unique powers and ability to lead. This was of course a misunderstanding.

It was the Icon of Sin that made contact with the Hell Portal buried in the middle of Doomguy's hometown on Earth. Once the USMC had received an intelligence report about what was leading Hell's army, Doomguy intercepted the Icon by travelling back to Hell. Upon arrival, he had slain countless demons while making his way to the Icon's chamber. Using whatever weapons he could salvage, Doomguy shoots the Icon's opened forehead and destroys it. Its death results in the closing of the second Hell Portal and the demonic forces falling into disarray.

Behavior and Abilities
The creature itself had no display of emotion during its encounter with Doomguy. As for its capabilities, it had the power to summon demons of all types minus Cyberdemons and Spider Masterminds. By doing so, it would launch a cube with skull faces engraved onto each side. Once the cube would make contact with a rough surface, the demon is summoned.

The Icon's only weak spot was the opening on the forehead exposing its brain. Upon defeat, all of the demons it spawned died with it.

Trivia

 * The alert sound for the Icon of Sin says, "Oremor nhoj em llik tsum uoy emag eht niw ot." It is actually audio that had been reversed. The actual sound is a voice saying, "To win the game, you must kill me, John Romero."undefined
