Martian Probe



The Martian Probe is a rare Hardmode, post-Golem flying enemy that can spawn anywhere on the surface and mostly found in the space layers (but not near the center of the map). 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.

They don't spawn in the middle third of the world. They will also not spawn if any of the Celestial Pillars are active.
