Monster Resource WAD
The Monster Resource WAD is a 2004 creation from the ZDoom community, spearheaded by Kara Rader (Nanami) and providing several new monsters to the Doom bestiary; which have since found their way to several other mods. It eventually was superseded by the Realm 667 "Beastiary".
The custom monsters are split into two parts: possessed zombies are placed in humans.wad, and the rest is places in monsters.wad. Both are found in the same zip archive, as well as two demo maps allowing to test the monsters.
The afrit (not to be confused with the Hexen afrit) is a fiery-red flying variant of the baron of Hell. It has no legs, instead its lower body is made of flames and sparks. It has a variety of fire-based attacks and is constantly orbited by two flaming meteors similar to those it can throw at its enemies. The sprites were created by Espi, though the attack frames were based on those created by Kristus for the "arch-demon" in Nimrod: Ixnay on the Hombre. Its behavior was coded mostly by Nanami. The afrit was one of the most popular monsters from the MRW, even appearing (adapted to DeHackEd) in Bloodstain, Resurgence and Scythe 2.
- Blood demon
One of the Skulltag monsters, it is merely a tougher demon with dark red sprites.
Another Skulltag monster, this is a cacodemon Jack-o'-lantern has twice as much health and fires a faster projectile. It has been given a new sprite set edited by Lexus Alyus, which shows them as bright orange, hollowed cacodemons with the eye plucked out and lit by a black candle placed inside of them.
- Cyber mastermind
Created by Nanami from the spider mastermind chassis and the cyberdemon's upper body, this monster combines both of Doom's boss monsters into one.
- Dark imps
There are three variants of the dark imp concept. All have twice as much health as the regular imp and the same recolored imp sprites, however they vary by their attack patterns. Nanami's own version shoots a homing projectile; the Skulltag version shoots a fast projectile; and the Void version (which, in Void itself, was merely a reskin of the undead warrior from Heretic) randomly shoots either a weak or a powerful projectile.
- Enhanced cacodemon
Visually similar to Skulltag's abaddon, this gray cacodemon created by Tormentor667 attacks with a spread of three fireballs.
Two small flying creatures created by Espi from Hexen sprites, with code by Nanami. The dragon familiar, based on scaled-down and cleaned up death wyvern sprites, has a ranged breath weapon; the bat familiar, using the bat SFX from Hexen, is limited to melee attacks.
- Fast imp
- Fire wyvern
- Hell guard
- Hell's fury
Using sprites created by Torm based on the recolored body of a Hell noble with black skin and white leg fur, and a head taken from the beta lost soul, this monster has been coded by TheDarkArchon to use two different projectile attacks.
- Hell warrior
Another Hell noble wielding equipment, this creation of Tormentor is a baron with a copperish tan skin carrying a recolored centaur shield. In KDIZD, it would get new sprites with a lion head and a fiery fist.
- Imp warlord
Originally a concept from Nick Baker's Doom Beastiary by Espi, it was completed by Espi and given its combat behavior by Nanami, alternating between five different attacks, including the ability to summon familiars. The sprites are created using elements from several Hexen sprite sets, notably the centaur and the cleric.
- Lord of Heresy
An edit of the beta lost soul by Tormentor667, coded by TheDarkArchon.
- Mauler demon
- Nightmare cacodemon
- Plasma elemental
Created by Stephen Clark (The Ultimate DooMer) and coded by TheDarkArchon, this is simply a pain elemental that shoots a stream of plasma projectiles. Its death throes likewise throw plasma in all directions.
- Rail arachnotron
An arachnotron equipped with a railgun, created by Torm and coded by Graf Zahl.
A recolored baron created by Nanami and limited to melee attacks. It would eventually get its own set of original sprites, created by Vader, in KDIZD; but in the MRW it is a Hell noble with tan fur on its legs and dark brown skin.
- Soul harvester
- Scorpion mastermind
Created by LilWhiteMouse, this is a boss monster similar to the spider mastermind in design. A scorpion-like robotic chassis equipped with a chaingun stinger and a rocket launcher claw, with a green brainhead shaped somewhat like that of a shark or lizard. The sprite set was created from a model of LWM's design and does not fit so well among the rest of the Doom sprites.
- Snake imp
- Stone imp
Created by Espi, this tough and spikeless imp variant is functionally closer to a slower demon.
- Super imp
- Tortured soul
A variant of the lost soul with black and orange flames that explodes on contact, created by Torm and coded by Graf Zahl.
- BFG zombie
A black-haired zombie equipped with a BFG9000 and which drops cells when killed, created by Graf Zahl.
- Chainsaw zombie
A zombieman wielding a chainsaw, created by Bouncy and with additional scripting by Graf Zahl.
- Plasma zombie
A zombieman in a bloodstained green armor that wields a plasma gun and drops cells.
- Rapid fire trooper
- Rifle zombie
A sergeant with ochre blood (supposed to be rotten meat) that uses very fast projectiles instead of hitscan, coded by TheDarkArchon and sprited by Tormentor667. The sprites are also used by the zombie railgunner.
- Rocket guy
Based on a monster from Obituary by The Innocent Crew, this masked zombie wields a rocket launcher. Available in two versions, one that is immune to splash damage and another that can kill itself by accident.
- Shotgun soldier
A possessed soldier with a clean uniform. Its shotgun fires seven pellets instead of three, same as the player's shotgun, making him more dangerous than a normal sergeant. The sprites were provided by NiGHTMARE, though he did not make them.
- Spread fire zombie
- Stealth fighter
Based on the "high-tech guy" from Obituary by The Innocent Crew, this enemy has a mostly transparent sprite set and a high rate of fire.
- Zombie marine
A zombie with a protective helmet and firing with an automatic rifle, created by Bouncy.
- Zombie railgunner
Coded by Bouncy and using the same sprites as the rifle zombie, this rotten sergeant wields a railgun. Four versions differing only by the amount of damage they deal are included.
