Reverse Polygons is Ground, but backwards, inverted, and reversed. It is almost impossible to tell apart Reverse Polygons from normal air. If Simpleflips, Mario, or BUP jumps into a closed 3D shape made of reverse polygons, they get sent to GBJ.

Reverse Polygons are also a extremely deadly drug if injected directly into the bloodstream, eaten, or snuffed, and over hundreds of people die from it each year.

This element is banned in all 64 states.
