Predictor

The Predictor is a Hardmode, post-Lunatic Cultist enemy that spawns around the Nebula Pillar during the Lunar Events. Its main attack is firing five Nebula piercer projectiles at the player, which travel in a straight line in a tight spread.

Trivia

 * It seems that, when preparing to shoot, its projectiles try to predict where the player moves, giving its name a meaning.
 * The name "Predictor" is likely a reference to the 1987 horror sci-fi film "The Predator", which features a futuristic trophy hunter alien known as the "Predator", who is the main antagonist of the film. Not only does the name resemble the Predator, but its design seems to draw inspiration from the predator, being humanoid with a large, brain shaped head.
