Lost Soul/Doom 64

Background
The Lost Souls of Doom 64 are ressurrected carcasses of those from Doom 1, resurrected by the Mother of All Demons. They are made from systematically altered dead carnage remade back into corrupted living tissue. The mutations were devastating. The Demons have returned stronger and more vicious than before.

It's Tough. It Flies. It's On Fire. These Lost Souls seem to warp into existence from another dimension. In some areas, there seems to be no end to them and their fiery attacks.

These variations of the lost souls look somewhat different, in their new mutaitons they have become slightly transparent, and there is fire only on the top of their skulls (the fire is also transparent). They also have more demonic face (similar to the Barons of Hell). They are also much more aggressive than their PC counterparts, with faster and more repeated attacks.

Info
It is also physically weaker than their PC counterparts and can be felled with a single shotgun blast (not unlike the variants found in the PlayStation and Saturn ports).
