Flaming zombie
From DoomWiki.org
The Flaming Zombie, or "Bernie" for short, is new to the Doom series as it is the first Doom monster literally set on fire. There are various reasons why this type is engulfed in flames, the most comman being fire ejected from busted pipework along hallways. What is mysterious is that during gameplay, it is possible to kill a normal Zombie (Doom 3) by lureing it through a firey broken pipe, yet these zombies survive.
Appearence
It's appearence is tall with "charcoaled limbs" and continuously burns. The clothes are tatterd and dark, but facial fetures are still intact. You can hear it moan in pain as it chases after a human. Otherwise, it is a normal zombie.
Combat Analysis
It is better to keep moving if it notices you, backwards if possible. It moves almost as fast as a Morgue Zombie so it is best to defeat it quickly. A few shots from a shotgun will destoy it, but using a pistol is somewhat risky.
