Crystal Empire

1: Crystal Infantry

Stronger and sturdier then even their earth pony ancestors, Crystal Ponies are not to be trifled with in close combat. Typically armed with spears and lances, they are keen on running down their enemy and smashing them to pieces for the Crystal Empire and Equestria as a whole.

2: Cryraptor

Cryraptor are giant mutant insectoids. These creatures have evolved a more dinosaurid appearance over time with pack like behavior. Their exoskeleton is extremely tough, akin to the evolution of most species around the Crystal Empire like the Crystal ponies themselves. Tamed by them over generations, these beasts are extremely deadly when faced in close quarters as they can rip and tear into their foes with ease.

3: Gem Mancers

These Crystal Ponies have learned how to bend the crystals around them. They can bend them, fire them, or use them as shields and armor, all while just using their own innate magic. This makes them especially deadly close by the crystal empire or in crystal caves, though they always make sure to bring sackfuls of crystals wherever they go, just in case.

4: Ice Archers

Ice Archers use especially large longbows in order to fire their ordinance. They have to firmly placed it into the ground and aim it from there. This is because their ordinance is large ice arrows. These arrows have been infused with the most intense of ice magic. Once they reach their target, they will instantly freeze anything they hit and the resounding area around it.

5: Great Swans

Peaceful by nature, Great Swans have always lent their wings to the aid of the crystal ponies. Their wind magic allows them to knock back their foes with ease and while they are usually peaceful, they can prove to be fearsome if provoked.

6: Cupids

Cupids are trained highly trained marksponies named after the god himself (though he tends to go by Eros these days). They are swift and nimble, able to dodge most any blow that comes their way before using their bow and arrows to pierce the heart of their foes. Their arrows use positive energy, making short work of any foe with evil intentions.

Sombra's Forces

1: Shadow Cryraptor Riders

Using dark magic, Sombra was able to fuse riders onto these beasts so as to have greater control over them. Armed with lances, they make for even more deadly foes. Not to mention that the dark magic corrupted the Cryraptor's body, making it so deadly bladed tentacles exude from around it, ensnaring unlucky foes into its clutches

2: Crystal Golems

Made from Crystals and sometimes Crystal ponies, Crystal Golems are massive, unflinching monstrosities that can easily crush and stomp their way through enemy lines without taking a scratch. Their crystal bodies make it especially tough to take them down.

3: Umbrum

Ancient creatures made up of dark matter itself, they drain the life of any unfortunate being they come across. Their intelligence allows them to study and work around an enemy's strengths before striking. They feed on hatred and are thought to be related to the windigos by many scientists and magicians.

4: Crystal Infantry

Akin to their uncorrupted counterparts, these soldiers fight for the dark realm and Sombra himself eagerly.

5: Yeti

Fearsome northern primates, these beasts have become highly aggressive and dangerous in order to survive. Initially trained by Sombra before his corruption, they made for fine additions to this army, especially after his corruption. The beasts eagerly tore apart any that the dark master wished dead.

6: Longbow Infantry

Using the more ancient longbows, they have greater range then most as well as accuracy. The infantry members tend to stick to the back of the armies and weed out the opposing force from afar.

so these units are native to both sides
