Brain Suckler

The Brain Suckler is a flying enemy spawned by the Nebula Pillar during the Lunar Events. It can latch onto the player's head, dealing large amounts of damage, and darkening all of the screen except nearby the player.

Trivia

 * Brain Sucklers pay homage to the iconic Headcrab enemy from the Half-Life series, as they attack by latching onto a player's head and disrupting their brain functions. Brain Sucklers are referred to as Nebula Headcrabs sporadically in the game's code, implying their name was changed at some point during development.
