Baron of Hell/Doom 64

The Baron of Hell appears as an enemy in Doom 64.

Background
The Barons of Doom 64 are the resurrected 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.

To quote the official manual for Doom 64, "You thought the Hell Knights were bad? These guys make them look like choir boys. You better have a good supply of ammo and armor to take on this demon."

It's mutations have given it a dark red color scheme (contrasting the greenish accent used for the Hell Knight). Their projectiles have also been changed to red instead of green like in the original Doom.

Info
The blood in its death sequence is red or green (depending on the NTSC/PAL and Japanese releases, the blood color can be chosen in 2020 rerelease on various systems).

In Doom 64, Barons are able to injure and infight Hell Knights, and vice versa.
