Martian Probe



The Martian Probe is a rare Hardmode, post-Golem flying enemy that can spawn anywhere in the outer two thirds of the map, but not near the world center. It is most commonly found in the space layer. It does not fly through blocks. The Martian Probe initially appears with a green light. When it spots the player, the light turns red, and it attempts to escape. If allowed to escape, it initiates the Martian Madness event. Strangely, its Bestiary entry will not unlock if it's allowed to escape.

They will not spawn if any of the Celestial Pillars are active.
