The Humanoid Grimm

"I remember how it looked at me with those burning blue eyes... We were all taught that Grimm don't have souls, so... Why did it cry when it saw me?"

- Ruby Rose The unnamed Humanoid Grimm is a major plot point and key figure in the story, "RWBY: From Darkness." It is the first known, recorded creature among it's kind, and displays characteristics never seen in Grimm before, and appears to be highly intelligent.

Appearance
Unlike the rest of it's soulless kin, this Grimm bears a humanoid appearance, wrapped in mist-like, black bandages that enshroud it's entire body, giving it the illusion that it is shrouded in black smoke, wearing a pair of obsidian greaves and black blades protruding from it's forearms. Like all Grimm, it wears a white, bone like mask over it's face, resembling a skull, though it has unusual blue markings rather than red, and glowing blue eyes.

Personality
Like so few of it's kin, this Grimm possesses great intelligence, recognizing potential threats and able to adapt accordingly to the flow of battle. It also possesses great intellect, able to find weaknesses in it's opponents, and analyze their battle strategy to a thorough degree, thereby allowing it to utterly destroy them. Like all Grimm, it has no sympathetic nature, nor empathy, killing anything with a "soul" or Aura. It also shows the traits of a skilled, powerful hunter, stalking it's prey relentlessly, and even should it escape from it, the Grimm will hint it down until it has found it's prey, and killed it. The humanoid Grimm also possesses a unique peculiarity where it "cannibalizes" it's fellow Grimm, absorbing what little remains of them into itself, which apparently heals it's wounds at a much faster rate, and seems to make it stronger, thereby making it a terrifying creature.

However, it does possess an oddity about it. For unknown reasons, this Grimm has an unusual fascination and longing for Ruby Rose, but not of the Grimm sort of obsession, where it has found worthy prey to kill. Rather, it shows a protective nature of Ruby, as it defended her while she was wounded against an Alpha Beowolf, slaughtering it mercilessly. It has also shown no signs of hostility to Ruby at all, instead displaying what could only be called worry. It has even shown itself to be able to feel some form of emotion, as it she tears when it stared at her face when it found her, injured. It has even demonstrated the unusual capability of speech, albeit rather course and intelligible, having muttered her surname, "Rose," clearly.

Powers and Abilities
The Humanoid Grimm has demonstrated a wide variety of abilities, though the full extent of it's powers are unknown.
 * TELEPORTATION - The Grimm has demonstrated the uncanny ability to teleport, disappearing from one location to another. The ability seems to have a short distance, and appears to dematerialze, as if being reduced to mere black vapors before reconstructing it's body.
 * STEALTH - It's most unusual ability so far is that the Grimm has the ability to camouflage itself into it's surroundings, and virtually erase most of it's presence, effectively making it hard to pinpoint.
 * WEAPON CREATING - Another of it's odd abilities. The Humanoid Grimm is capable of forging weapons from it's smoke-like substance around it's body, demonstrating a fearsome and versatile fighting capability. So far, it has been shown to create swords and axes.
 * SHADOW MANIPULATION - The Humanoid Grimm possesses a strange power to virtually control the shadows around it, forging a sort of "camouflage" for it, and even able to assume the illusion of creating other Grimm, though experienced Huntsmen are able to easily see through it. That being said, slights of hand are not it's only tricks, as it has even demonstrated able to use it for combat purposes as well, allowing to traverse around the combat zone, or even temporarily immobilize it's enemies.

Notes/Trivia

 * 1) While Ruby's encounter with the Grimm marks the first known instance of humanoid Grimm actually existing, it as suggested by Ozpin that there was another encounter with such an existence in the past, and given the context, it can be inferred that it was related to Summer Rose. This may also explain the Humanoid Grimm's obsession with Ruby.
