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. The Predictor will not shoot if there are solid blocks in its way. It somewhat resembles the Moon Lord with its brain showing and little white things on its belly.
