Lost Soul/Resurrection of Evil



The Forgotten One's form is an echo to the original Lost Soul's shape in the previous Doom games, excluding its form in Doom 3. It is a flying skull with two demon horns, and floats with a stream of flame behind it. Its only attack is flying towards its enemy and biting. The Doom 3 incarnation of the Lost Soul does not appear in the expansion pack so the Forgotten One could either just be the replacement for the Lost Soul.
