Lost soul

The Lost Soul is a flaming, flying skull first introduced in Doom's second episode, The Shores of Hell.

Doom II furthered the use of the Lost Soul by utilizing them as the projectile weapon of the new Pain Elemental monster. The Doom manual gave this description of Lost Souls:

"Dumb. Tough. Flies. On fire. 'Nuff said."

morons morons morons lost souls are idiots and morons

Tactical analysis
The player can stop a Lost Soul's charge by shooting it while it is attacking. Because of their 100% pain chance, it is often safer to use the pistol, rather than the slower-fire shotgun, so the Lost Soul will not have enough time to retaliate. Also, Lost Souls will stop when they cross an object in their charge path, ie a shotgun or medikit, stopping them like they would a wall. Using rockets against groups of Lost Souls is definitely not recommended, as there exists the definite possibility of a Lost Soul suddenly flying towards you, causing one of your rockets to explode close to you, causing damage to yourself.

Appearance statistics
In classic Doom, the Lost Soul is first encountered on these maps:

The IWADs contain the following numbers of Lost Souls:

Doom RPG
In Doom RPG, the Lost Soul appears as a class of monster. There are three variations, identified by color:


 * Phantom (green)
 * Lost Soul (normal colors)
 * Nightmare (blue)

Lost Souls can move three panels in a single turn instead of one, and will attack automatically once they are in an adjacent panel to the player, even if it has already moved. It attacks three times consecutively and can be damaged by the Fire Extinguisher.

Doom 64
These variations of the Lost Souls do not look much different except that their skulls look more realistic and there is only fire on the top of their skulls.
