Baron of Hell/Doom 64

The Baron of hell in Doom 64 is given a red-orange colour scheme, rather than green, which is instead used for the Hell Knight.

Background
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 can also injure and infight Hell Knights and vice versa.
