Tidequeen - female rulers of the Naga. They have four arms and walk on three tails. They have two tentacles with stingers - stabs from them can cause paralysis. They can also cast several spells - Frost Armor, Lightning Bolt, Paralyzing Shock, and Charming Whispers, which has a minor chance of driving a creature berserk, lowers focus and willpower, causes erratic behavior, and also induces feelings of arousal and servileness.
Faceless Darkweaver - a rare magic-user caste - they have thinner tentacles, and are smaller than regular faceless ones, but larger than the Unbroken. They can throw Shadow Bolts, and can cast Soul Drain and Curse of Agony.
Constellar - energy beings, servants of the Titans. They observe the world, and are rarely found in all good biomes. They cast some powerful magic, being able to throw energy bolts, cast Moonfire, Sunbeam and Gravity Crush, which causes a short-lasting but major agility and speed reduction.
Voidstrider - void-infused striders, found in evil forests. Not actively hostile, but their bites can cause the "void touch" debilitation thats also shared by the Voidwalkers and related beings. Races with access to evil animals may use them as mounts.
Water Strider - insects that can walk on water, found in grasslands, lakes and rivers - can be used as mounts. Non-hostile - they are also utilized by the Jinyu as pets.
Zhevra - horned dwellers of savage savannas and shrublands. Can be used as mounts by races who settle nearby - their horn stabs are deadly, but they aren't actively hostile.
Frenzy - toothy fish found in savage lakes, rivers and oceans. They are predatory, and quite large compared to most other fish, which can make them a potential danger.
Abyssal Worm - worm-like creatures found in savage oceans. They can fly, despite lacking any means of doing so - Naga also use them as pets.
Kraken - colossal octopus-like creature, found rarely in savage oceans. It attacks with all of its tentacles at once, and can also bite with its toothy, circular mouth, and stab with the barbs at the end of its tongue.
Abyssal Lurker - another rare savage ocean dweller - it attacks by biting, slapping with its flippers, and stabbing with the spikes at the ends of its flippers.
Draconian Aberration - failed, artificial draconians, found in evil mountains. They are semi-sapient like trolls, and while smaller, are also immune to heat, and do not feel fear or pain. Twilight Cultists and Black Draconians also utilize them as innate pets.
Lunarwing Owl - large owls, found in good forests and grasslands. They can be used as mounts and war animals. Their wooden antlers enable a gore attack.
Ancestral Phoenix - large birds, found in good shrublands and savannas, and used as mounts and war animals by the Pandaren.
Elemental Spirits - found in good grasslands. There are four variants - Fire, Earth, Air and Water. Earth has horns, and Air has a beak, but otherwise have the same body build and size, and all can use various elemental abilities. On death, they only drop their masks behind - depending on the type, the metal is different - incendicite for fire, obsidium for earth, aerocite for air, and hydrocite for water.
Sha Spirit - corrupted elemental spirit, found in evil grasslands. Is unintelligent, unlike its uncorrupted brethren. Throws shadow bolts and can cast Curse - will also pull levers.
Alemental - artificial, unintelligent elementals utilized by the Pandaren as pets. They can spray alcohol both in a directed and undirected spray, and their bites inject alcohol into the bloodstream of their foes.
Forest Sprite - small humanoids made of bark, found in good forests. Are mischievous, and will steal whatever they can get their hands on - they are also cowardly and will run away quickly.
Water Sprite - sprites that dwell in good lakes. They are nearly identical to the Forest Sprites in terms of functioning, but are amphibious, and are also immune to some water and ice magic.
Mountain Sprite - sprites that dwell in good mountains. They are slightly larger than the other two, and are also fearless, and won't hesitate to gang up on anyone who crosses their path. They'll still steal goods, but have no interest in pulling levers.
Sha Brethren - sha-possessed Pandaren, found in evil grasslands. Their scratching and biting attacks are quite deadly, and they are also tough to debilitate. They can spew a stream of black sludge that causes pain, vomiting blood and erratic behavior.
Zombie - regular, mindless undead. They have several minor variations - regular zombies have both arms intact and nothing else special to note -
one-armed zombies, as their name indicates, lack one of their arms, making them a tad more predictable -
perforated zombies are pierced with several arrows, which can potentially deflect attacks if aimed at (butchering this zombie type also yields three iron arrows) - and
scabbard zombies, who are pierced with a long sword - the same principle applies, and butchering them also yields a single iron long sword.
Void Elf - High and Blood Elves infused with the void - they appear alongside High Elves, and also have an entity available in the Additional Entities addon. They can throw Shadow Bolts, buff themselves with Consume Shadows, and their scratching attacks can induce the "void touch" debilitation.
Lightforged Draenei - only in the Derivatives addon. They are light-infused Draenei who feel no fear, and require no sustenance - they are slightly less opposed to violence as well. There are also no Broken amongst their ranks.
Lightforged Battlesuit - mechanical, flying suits used by the Lightforged - also only in the Derivatives pack. They fire bolts of holy energy with their cannon, and attack with punches, kicks and cannon bashes.
