Lunar Tratix is a remote planet in the Hero Factory Universe.
When Preston Stormer was corrupted by nanobots that caused him to go mad, Nathaniel Zib sent Heroes Jimi Stringer, Dunkan Bulk, Natalie Breez, and Mark Surge to retrieve an ingredient for the "antidote" to the nanobots. This ingredient was found only on Lunar Tratix. When the Heroes arrived at Lunar Tratix, a Tratix Reptoid attacked them, but Breez convinced it to get the ingredient for them using her unique nature ability to communicate with creatures. The Heroes then departed and administered the cure to Stormer and Drax.
The surface of Lunar Tratix resembles a barren rock field, with red-gray stone making up the land and peculiar rock formations dotting the surface.
