Damaged Ender Demon (Mythical creature contest)

The Damaged Ender Demon is a creature seemingly made from a mutated Enderman, an amalgamation of the void, or a combination of the two. It is missing an arm, and its shoulder is covered in veins. Its remaining arm is extremely large, veiny, and strong. It visibly becomes more dense with a purple fluid further down said arm. Its torso is also twisted opposite of what would be considered a normal for most anthropomorphic organisms. The name was given to it based off of its resemblance to demons.

Behavior
Ender Demons are hostile, and a damaged one can sometimes be even more hostile. It absorbs dead organic material to stay alive, and the open wound of its arm can cause it to lose the energy it obtains from absorbing its victims. This makes it even more important to hunt down as many living organisms to absorb.

Its attacks are derived from use of its arm and sharp claws. These attacks include claw swipes, backhand slaps to knock back opponents, grabbing and throwing objects and organisms, and pounding the ground to create shockwaves in its surroundings. On rarer occasions, Ender Demons can teleport, though not as commonly as normal Enderman. It is also rarer to see a damaged one do such unless is is struggling in battle to preserve resources.

Loot
The most common drops that can come from a slain Ender Demon are Ender Pearls and Eyes of Ender. They can also drop the weapons, armor, and tools of those that have died and been absorbed after doing battle with it.

Void Essence
On some occasions, vials containing a fluid labeled "Void Essence" will be dropped from the creature upon being slain. It does not last long outside of the vial on its own after it has been opened, so ingesting it is effectively harmless. However, it has a wide range of different effects when in contact with different materials. One of the most well-known cases of this is injection from the vial into living organisms. This causes a large purple scar to form around the area of injection, however it does not seemingly harm the organism. More research is needed to verify this. The religion of Voidmun in Southeast Eldham is infamous for injecting some of its followers with Void essence, however it is obtained by alternative means.

"Prototype MEFS - Escape Protocol"
One unique item that can be dropped from the creature is a book titled "Prototype MEFS - Escape Protocol". The book lists the author as "Aimatos". It helps to further understand the circumstances from which the creature emerged from. The book is as follows:

Escape Protocol

''In the event that any Prototype of the MEFS deviates from the shape that the operator of [REDACTED] controls it to flow in, this creates a high risk of the void essence to flow into the restraints designed to keep it in place. This is especially dangerous as the prototype has not been subjected to [REDACTED] yet, meaning that its hostility is not yet removed from Aimatos personnel. It may be able to break the other restraints holding it together. In the event that any prototype attempts to escape, the following measures should be''
