Lost soul (Doom 3)

The Lost Soul in Doom 3 is a human female face on a flying rocket engine contraption. Its jaws are torn apart to allow it to open its mouth wider than a normal human could and its teeth have mutated to long, pointy monster teeth. They fly and charge at the player, similar to the classic Lost Souls, but can cover a larger area, by changing course if necessary.

Doom 3's version of the Lost Soul is very weak. It can be taken down by a single punch if necessary, although it takes two pistol bullets to kill.

The Machinegun or the Plasma Gun are the most efficient weapons for taking down Lost Souls, thanks to their high accuracy and rapid rate of fire.

The Resurrection of Evil expansion pack included a new monster called the Forgotten One, which bears a closer resemblance to the classic Lost Soul.
