Sulephet - Warhammer Fantasy

Morathi's dark Pegasus, a "coal-black burning-eyed hell-steed", explicitly looking at her with "lust and hatred and a curious, twisted love" (kind of how she looks at her own son).

There's not much to him beyond that. He's a chaos creature Morathi rides and most people around her are intimidated by.

The black beauty - the Witcher 3

One key quest in velen has you choose between helping and killing a spirit bothering the locals. The quest comes from the explicitly villainous Crones, and the spirit tells you children will die if you don't help her save them.

Which is true. The Crones eat the orphans if you don't help the spirit possess a horse.

The problem is that the game hints quite heavily on the spirit being worse than the Crones. And in choosing to save those kinds, you unleash her upon Velen.

Dinosaurs in Jurassic park

The entire population created in the lab is female. By design. So it can't reproduce out of control.

Except they used frog DNA for fill gaps in the fossil DNA they used. And apparently the frogs in question can be hermaphroditic when needed.

Amazon's in DC comics

Female only magic ethnicity. The explanation varies from souls of abused women ending up there, to raiding ships, conceiveing children, murdering everyone on board, then selling the baby boys into slavery.

Take your pick.

Sisters of mercy - endless legend / space 2

Nuns with guns dedicated religiously to the concept of doing good. They build settlements, heal the ill, and defend the people who need it. Within their means, they are a minor faction.

Their population growth is not explained. I expect it's a combination of recruitment and actual reproduction with the people they protect. Edit: it apparently is mostly recruitment.

The Prophets ("wormhole aliens") from star trek

The gods of Bajor. They perceive time non-linearly, influence events across time, communicate with the bairns through orbs, and have at least once saved Bajor by making an invading fleet travel through time as well as through space, when they tried to reach Bajor via the wormhole.

They're detached, and view people as tools, but they do help when they can (interfering too much could create paradoxes).

The umbral choir from endless space 2

An entity from another galaxy, gaining sentience, sapience, and a life purpose upon encountering the galaxy of the endless.

It wants to end all war and heal the galaxy. It possesses people and uses them as agents of its will. It prefers to remain undetected.

Also, hacking. It's great at hacking.

Not much, all things considered. 2 planets (that don't have to be yours) are small potatoes by the time you can destroy them.

The APU from star trek

The Parlor and the Cravic went to war with each other. They both created automated personnel units to do the fighting for them.

The war ended, the APU destroyed both of their creators, then kept on fighting each other.

They can't make more of themselves, so every loss counts down to their extinction.

The Rachni from Mass Effect

The Protheans selectively bred them for war. Which was too successful. They rebelled, and the Protheans "had to burn 200 worlds" to beat them.

The reapers harvested the Protheans, but not the Rachni, who remained. And became a mascot problem in the following cycle. Which led to the uplifting, and then rebellion, of the Krogan.

The cravers from endless space.

The virtual endless created them as a scorched earth weapon against the concrete endless, towards the end of the civil war that destroyed both.

They outlived the endless, and continued their two objectives: grow and consume.

They're a playable faction that extracts resources faster, but depletes planets.

The Ents from Tolkien's legendarium.

Made, as I recall, to keep the forests safe from dwarves. They're extraordinarily old, and tend to keep themselves and their trees.

Isengard falls to their assault during the war of the ring.

Treemen (and dryads) from Warhammer fantasy

Forest spirits that bound themselves to trees. They can move, speak, and use magic. They defend the magic forests and hate intruders. That includes the wood elves that bring more trouble than they help with.

Winter brings them to a halt, which makes the wood elves a necessary evil to them.

Unfallen (and guardians) from Endless space 2

A species of sentient trees (created by one of the "old gods"/lost)

They're defensively oriented and geared towards high approval and influence assimilation as opposed to conquest.
