Skeleton Spear

Skeleton Spears are Skeletons that wield a variety of types of spears. The first skeleton spears were on rafts in Castlevania: Rondo of Blood and attempted to knock Richter off of his raft. They later wielded Halberds in Castlevania: Symphony of the Night and other games. The Skeleton Diver in Castlevania: Curse of Darkness is armed with throwing Tridents and rides a giant skeletal fish.

Castlevania: Curse of Darkness
The Skeleton Diver is a skeleton who wields a trident and owns a skeleton fish. He and his fish guarded the Bird Type Innocent Devil near the castle entrance (which was covered by water at the time). He most likely died after Hector defeated him, although his fish has reappeared in Castlevania: Order of Ecclesia in the background of the first water area and in Castlevania: Judgment in the castle entrance, where he harasses the players by destroying parts of the bridge to the castle.
