This prompt is Ogre..
So here we are... this is an Ogre.... And Victoria making bad decisions as usual...
Just as a goblin can become an orc, an Orc can feed on flesh and chaos and perform a ritual akin to that which summoned the first chaos avatar, they will enter a state of hibernation, entering a cocoon and emerging as one of a few things. If the Orc simply revels in bloodshed and chaos, or does not properly finish the ritual, as is common, they will emerge as a Troll. A being of utter destruction. If they complete the ritual properly, they will emerge as an Ogre, a powerful and intelligent chaos being. If however they perform the ritual and are either bound by contract, possessed by, or stumbled upon by a demon or evil spirit, they may become an oni, which fuses the power of a Troll with the mind of a demon, a creature which can rival even an Ogre in strength.
Ogres are thankfully rather rare, as the Orcs that participate in the ritual to become an Ogre must make proper calculations and have an indomitable will to not give into the urge of wanton, pure destruction that the chaos suggests of all living things. Though Trolls may be more dangerous as cunning, nearly unkillable violent animals, Ogres are potentially much more initmidating as they are equally as difficult to kill, however they possess a cunning intellect to match their ability to kill. When an Orc successfully evolves into an Ogre, it emerges much larger and much more capable, often times with a full tail of spikes, and more spiny protrusions from it's shoulders and arms that it can extend to use as weapons, and a pair of deadly antlers on it's head. Their teeth grow too large for their mouths and if they didn't before they begin to gain additional eyes in their sockets.
Ogres are very large, standing at upwards of 15 feet tall in some situations, and usually a minimum of 8 feet tall, though young creatures that are born as ogres may be smaller. Ogres possess a spark of clarity that trolls do not possess, granting them the cunning of a serial killer or psychopathic tendencies to trick and lie to creatures to get what they want out of them , or to inflict pain and suffering on a creature to cause it misery and misfortune. Ogres are almost always the leaders of groups of Goblins, Orcs, and Trolls if they should all be working together, and many times Orcs and Goblins will defer to an Ogre, even one they don't know, if one arrives to wherever they are stationed.
Ogres can afflict creatures with their own blood, inciting madness and chaos by cutting themselves and feeding the blood to other creatures to corrupt them into orcs or goblins, and can use this blood to insight frenzy in other chaos creatures, or to inflict pain on them. In addition they often possess some mastery of chaos magic, which results in various knowledge of humour magic or specifically manipulation of their own black blood, to harden it in their veins and appear more dense and difficult to harm, or allowing it to become a bloody whip or blade, or even a projectile, though they an also create energy blasts from chaos magic that they unleash from their hands. Their manipulation of blood magic also allows them to take control of creatures that have consumed their blood to an extent, and they can teleport through their own blood, and even transfer their consciousness to some parts of themselves should they be severed. Unlike a troll, parts of ogres cut off of them won't grow into a new Ogre, however they could potentially transfer their consciousness to that part and regrow the rest of itself from that specific limb.
Ogres may be spellcasters or powerful fighters, and some may be alchemists, and they may perform hideous experiments on other creatures, with Ogres being likely to approve of the various Goblin fleshwarping, and encourage creatures to be pushed to their limits and beyond. Ogres that are generals in war often take trophies from the creatures they have slain and wear human skulls and bones on belts to appear more intimidating. Though many keep tribal appearances, some may still wear armor of any variety that they wore before, with heavy armored full plate.
Like Goblins and orcs, Ogres can reproduce with any living creature, and in doing so they can produce a plethora of strange beings, though their genetics aren't quite as malleable as they once were as Goblins, or even as Orcs. It is incredibly difficult for them to do so, however it becomes increasingly more possible with aid from Goblin scientists. Children born from Ogres are often pure ogre, which tend to be more powerful than normal Ogre as they develop their mastery of chaos magic at a young age and do not need to spend the time transforming into an Ogre. However this means they often do not have to practice the same types of discipline, and often times these orcs delve deep into madness and become more troll like, or become Buggane, also known as Ogrepsychos, or Wild Ogres, which are Ogres that have the cunning and the tactics to kill but go on a psychotic break and begin hunting down whatever they can like a slasher from a horror movie with very few goals, and even killing others in their clans for the fun of it.
Ogres that become possessed by various evil spirits may become Oni, and take on new but similar forms. Oni whom become incredibly powerful and win many battles, may receive whispers from the chaos, and may be encouraged to seek out becoming the host of Chaos, casting aside itself so that it may live on forever as the Avatar. The Avatar of Chaos being the entity that corrupted these individuals, in the first place as it's blood seeped into the land around Urth. Most Ogres already take on the appearance of Chaos, or one very similar, and their praise toward the brutal eldritch god pushes them closer to bringing the realms into the abyss...
Ogres are much more common on Urth than on Earth, though occasionally corrupted creatures that continue down their path of destruction may evolve into Ogres in the modern wold and need to be hunted down by P.R.I.M.E.
