Roughly the size of an eight foot tall human, a rather small monster actually; however with its appendages it can stretch to incredible lengths.

[b]Stats:[/b] 
D - S
[i]Strength[/i] - D
[i]Durability[/i] - C
[i]Speed[/i] - B
[i]Agility[/i] - B


[b]Abilities:[/b]
[i]Cloth Binding[/i] - Using its cloth like appendages, The Hollow One can wrap and restrain its victims with ease.  It will attempt to strangle or even just plain suffocate its enemies to death.  The cloth strips have a long reach and are deceptively fast, able to quickly entangle a target.

[i]Metal Rings[/i] - On the ends of some of the strips are metal rings with which the monster can bludgeon its opponents with, adding another layer to its bandage attacks.  Simple but effective.

[i]Wings[/i] - Wings allow the creature to fly around quickly and even raise heavy wind gusts with which to blow its enemies around with or even deflect projectiles.

[i]Extreme Flexibility[/i] - As a creature with seemingly no body inside of its wrappings, the creature can twist and contort its body quite easily, allowing it to bend out of harms way and fit in extremely narrow places.

[b]Behavior:[/b] 
The Hollow One prefers to get the jump on its prey in an attempt to snuff it out quickly within its embrace.  When in combat, the creature uses its flexible body to try and avoid danger while attempting to grab its opponent.  If it feels that being close to a certain enemy is too dangerous the creature with attempt to smash it away with its heavy metal rings, or blow it away with powerful wind gusts.  The creature has a degree of intelligence as it will often try to lure an enemy into an unfavorable position in which it can easily pounce and incapacitate the target.[/center]
