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, putting his name a meaning.
