World of Academia: Grimmudes

The World of Remnant is not the only world in the viewable multiverse. There are indeed multiple other worlds out there. Most of them lack things like Aura, Faunus, Dust, and especially Grimm while some have substitutes for them. One world in particular shared Remnant's technology. At least, a certain aspect of it.

In a distant world, one scientist wanted to create a race of robotic beings that would learn by synchronizing with humans, hoping to better the world through it. However, after failure after failure soured him, he was driven to insanity and re-purposed the robots to synchronize with humanity's more... darker aspects. Negative emotions in hand, the robots began to evolve into nigh-unstoppable killing machines, and it was only with their world's version of Huntsmen that they were put to a stop.

Though, some time later, these machines came back from their destruction and were placed in another world. This world was also not like Remnant, but it had one thing in similarity to Remnant: Grimm. Eventually, the robots made to replicate negative emotions became easy pickings for the Grimm who sought out negative emotions. However, with this, a new evolution was made.

As the Grimm tore apart the robots, they began to emulate their carnage and bloodlust, becoming less man-made machines and more creatures of darkness. They were no longer what the scientist called Roidmudes, but rather a new breed of Grimm: Grimmudes.

Grimmudes take the form of Grimm, though with one key difference: the body of a Roidmude will always be found acting as its torso. The powers of a Grimmude depend on two things: the type of Grimm and the type of Roidmude that fuse together. Though for the most part, the Grimmudes would always be the combination of a Beowolf and a low-class Roidmude, so expect a Beowolf to have either the climbing of a spider or the flight of a bat.

The Grimmude is able to create duplicates of the Roidmude's former form. However, there is a cost. These duplicates are born from the Grimmude as it essentially divides its Grimm portion to make more copies. In a way, it is creating what are called Fractal Roidmudes. As a general rule of thumb, the higher number a Roidmude has on its chest, the more Fractal Roidmude it can create. The number on a Fractal Roidmude's chest is an indicator of how strong they are. With each Fractal Roidmude created, the Grimmude grows weaker and weaker, leaving it being able to be taken down with ease.

However, this world that these Grimmudes lie in... It doesn't have any Huntsmen native to it and thus, they rely on Huntsmen from other worlds, displaced from their own...
