There are three types of Handenemies in the Castlevania series. All of them will attempt to grasp onto the player from a different angle of attack, either it is from the ground, from the side while floating, or from the background.
Appearing only in graveyards or nearby areas. The hands of the reanimated corpses buried there will pull out from the ground and wait for an unfortunate victim to grab a hold onto. They can be specially dangerous as they require many whiplashes to destroy (specially at night) and can deal medium to heavy damage. If Simon decides to jump over instead of destroying them, he can be suddenly overwhelmed by other enemies, like Slimes or Freddies.
Hands start appearing in the Simon's Quest (LCD Handheld) game at the graveyard stage at night, and keep appearing on each subsequent stage. They pull out from the ground and wave around, causing damage. They cannot be destroyed and they impede the player's movement forward, so they must be jumped over.
2. Graveyard (night), 3. Castle, 4. The Castlevania
Wall Hands come out from the background, grab Simon and hold him in place while a Skeletal Knight comes to strike him with its sword. If the Skeletal Night is defeated, the Wall Hands will perish along with it.
A group of damned souls' arms, called Dead Man's Hands, flail around on the ground as a trap in Rondo of Blood. If the player is unfortunate enough to be grabbed by these, they will drag them deep underground resulting in an instant death.
The Evil Hands from Circle of the Moon are floating, grasping severed hands. They appear in several areas, including the Eternal Corridor and the Underground Waterway. They inflict only minor damage but they will latch onto Nathan and cause damage over time, in addition to restricting his movements, leaving him open for further damage from surrounding enemies.
