BeetlesThe beetle is a stronger fighter and flyer than the fly, but is not as fast. One of the first creatures you get in the game, and they gain the ability to freeze when they reach higher levels.
Bile DemonsWhile slow, the bile demon is still an excellent fighter, and manufacturer. They are immune to gas and wind attacks, but are vulnerable in combat to most types of undead.
Dark MistressesThe kinkiest of all creatures, one who enjoys pain and inflicting it on others. She has no special job apart from visiting the torture chamber to be tortured. Slapping her makes her happier and she rushes off to a battle as soon as one starts. An excellent fighter.
Demon SpawnA fairly good fighter, that can walk over lava unharmed. Spends most of its spare time training. After your demon spawn trains to level 10, they continue training and level up into a level 4 dragon
DragonsThe dragon is one of the toughest creatures in the game. Quick to learn from training, and a good resource in any library. As you would expect, they are immune to the effects of lava, and actually gain experience from sleeping next to it.
FliesThe fly is a weak fighter and does not last long in battle, however they are a very fast unit and great for exploring as they can fly over water and lava.
GhostsWeaker than the skeleton in fighting ability, the main use of the ghost is in research. Given the chance, these creatures will tend to concregate in your temple and will need manual duty allocation. Ghosts can fly, see invisible creatures, and are immune to poison gas.
Horned ReapersThe horned reaper is the most destructive, psychotic fighter of the game. Summoned only using your temple, they are one of your fastest creatures, and have the power to slow any enemy fighting them. The reaper is immune to lava and has a good field of vision. If allowed to get annoyed (which happens very easily), they will go on a general rampage. It's best to build them their own personal dungeon, behind a locked door.
HoundsThe hound is a good fighter and has the ability to travel safely over lava. Hounds will tend to follow your more powerful creatures around as bodyguards, but will attack your own Demon Spawn if given the chance. Placing Hounds in your graveyard will speed the appearance of Vampires.
ImpsThe imp is the basic laborer, who carves out your dungeons, mines your gold, reinforces and decorates your dungeon, and carry things like bodies and traps around. Imps are the only creatures that give their loyalty for free, and are also the only creature that can be created magically, however the price to create an imp increases with the number you posses.
OrcsThese are good all round warriors and like to be allocated guard room duties. They are quick to learn from training, and form a good basis for any close quaters combat. Orcs will refuse any research based duties.
SkeletonsThe skeleton is another good fighting unit at high levels, and they are attained when a humanoid creature starves to death in your prison. Skeletons advance quickly when trained, and are immune to the effects of poison gas.
SpidersThe spider is your first reasonable fighting unit. Good physical attributes are complimented well by a nice selection of combat abilities. The spider responds well to training.
TentaclesThey hit quite hard and are fairly tough, which make them good fighters when combined with their freeze ability.
TrollsThe troll is best used for manufacture, and has been known to turn down less manual jobs, such as research. Initially poor in combat, the troll gains good firepower at later levels. However, they are unlikely to use range attacks unless possessed.
VampiresThese undead creatures are vicious fighters and very skilled scavengers. They prove good researchers but will refuse to stay in your workshop. After a vampire's experience is above three, it becomes immortal, and can resurrects itself in its Lair after it dies, at the cost of 1 experience level. As with other undead, vampires can see invisible creatures and are immune to the effects of poison.
WarlocksThe Warlock is good at both research and manufacturing, has a good range of attack spells, and gains vast experience if their lair is placed next to an unmined gold square. Unfortunately, they are also poor in close quarter combat.
TunnelerThe equivalent of your Imp unit, Tunnelers lead parties of stronger Heroes into your Dungeon, clearing their path to your Dungeon Heart. They are easy to dispatch, and even the weakest of your Creatures should have no trouble vanquishing them. They are no use to you, and should be left to rot in Prison.
DwarfEssentially Tunnelers without the Dig ability, these units will be heavily encountered in the beginning levels and are easily dealt with.
ThiefHuman units that are easy to kill, and are often encountered with Dwarfs. They will rob you of your gold if they make it to your Treasury and will turn into a Level 4 Knight when trained to "Level 11". Should be converted or sacrificed.
ArchersLook similar to Thieves, are are basically the same unit strength and usefulness-wise. Archers have a wider range of abilities, however, and can fire Navigator Missiles as well as Arrows.
WizardsMonkFair fighters who do combat with a whip. They can be formidable foes.
BarbarianStrong warriors who appear often throughout the game. They fight with a battle hammer and in great numbers, are deadly
PriestessPowerful spell casters with a weakness in hand to hand combat. They protect themselves from this by using a wind spell to literally blow away the competition.
FairySimilar to the Priestess, not as powerful but usually come in large numbers.
GiantA powerful melee fighter.
SamuraiAn excellent fighter, very quick and a good spell caster.
KnightA.K.A. The lord of the land. There is one knight per level unless you train a thief past level 10.
The AvatarYou may have seen this guy before. The most powerful warrior in the game. The Avatar makes two appearances in the final level. He owns all the realms you had previously taken over.
