Usurper

The Usurper is an enemy in Marrow.

Description
The Usurper appears in several long corridors throughout the game. They will spawn infinitely from either edge of the screen and run towards the player, dealing damage as they pass through before disappearing into the other edge of the screen. They have the appearance of white a humanoid.

Usurpers will die in one hit, but are difficult to fight against because of their infinitely spawning nature and semi-transparent state, making it difficult to see before it is too late. Sometimes two Usurpers will spawn from opposite sides of the screen, rendering it impossible to deal with both without taking damage.
