Hand

"The corpses that the minions of Tchernobog use to make zombies aren't always in the best of shape. Sometimes, only a limb is salvageable. Usually, the Cabal's surgeons can fashion various bits and pieces into a serviceable undead soldier, but certain leftover parts can be effective all on their own. If one of these horrors gets hold of you, you've got to push it off before you can kill it."

- Blood manual

Hands, also known as Hell Hands, are small yet common enemies appearing in both Blood and Blood II: The Chosen.

Description
Hands are nothing more than severed human hands that walk around with their fingers like a spider.

Blood
While walking around, they constantly say "I'll swallow your soul!" in a high-pitched voice. If one Hand get close enough to Caleb, it will leap on him and choke him to death. To prevent the death of asphyxiation, press the space bar repeatedly to disengage the Hand, and then shoot it before it springs back to Caleb. The Sawed-Off Shotgun is the best weapon to blast them down.

Although, since they don't come in great pack, only one Hand can grab Caleb by his throat at a time.

Blood II: The Chosen
While the Cabal no longer uses proper Zombies. Hands make a return in Blood II and are still nuisance enemies that function the same way as they did in the previous game. interestingly enough however, if the hand is damaged it will flip the bird and will continue to keep up this vulgar gesture until Caleb gets close enough for them to chase after him again.

Official Bestiary
These spider-like menaces would love nothing more than to get their fingers around your throat and squeeze. Watch for them scuttling along walls and ceilings. The last thing you need is a handshake from one of these fiends.

Trivia

 * From the official Blood website's bestiary page, the Hands can walk along walls and ceilings. However, it never happen from in-game as they only walk on floors/grounds.
 * Hands are possibly a reference to Thing, a disembodied hand character from The Addams Family series.
 * Their "I'll swallow your soul!" line and flipping the bird in Blood II is a direct reference to the horror film trilogy Evil Dead. Which coincidentally also had a living severed hand as an enemy.
 * After getting asphyxiated by the Hand and then enabling the cheat code to receive 200% health for "resurrection", the Hand who previously killed Caleb seems to disappear.
