The Swarm

NOTE: BECAUSE THIS IS A PRETTY BIG CONCEPT THAT IS UNLIKELY TO APPEAR IN THE SOURCE MATERIAL, THIS WILL BE STRICTLY FOR A WHAT IF/AU FANFIC.

The Swarm are a group of around 200,000 creatures of Grimm under the care of the 'God of Grimm' and Janitor 04, John Dog. All of the members of the Swarm originate from being injured in either a fight with a Hunter or another creature of Grimm and were healed by John giving parts of his regenerative soul and in turn Aura to them. This makes the Swarm unique among the creatures of Grimm as the only ones who have a soul and in turn, due to all of the souls being identical, can almost be considered as a singular entity, like the neurons of a brain.

The Swarm follows John's beck and call, relaying information to him at an almost grand scale, while helping him do his job as a Janitor by cleaning up in the shadows of the night. They are identifiable from normal creatures of Grimm by their previously red eyes now coloured with the light yellow of John's Aura.

Abilities
The bulk of the Swarm's collective power is covered under John Dog's article, with an almost overwhelming potential due to having almost every type of non-unique creature of Grimm (excluding everyone else's Fan Created Grimm) and hence can readapt their numbers to counter any threat. What is mostly left is the specific capabilities of the more important and powerful creatures of Grimm in the pack, known as the Prime, which John specifically designated as CEOs of sorts to process the gargantuan load of infomation from the Swarm's extensive senses, as well as relay the commands that John gives. The Prime Grimm are mostly based on fairy tales, such as Alice in Wonderland, and famous novels.

Prime Grimm
White Beauty  - The very first Grimm that John had added into his Swarm by pure accident. He takes the form of a white-coloured stallion and is the weakest Prime, but the most loyal and charismatic.
