Roxanne Trel

Roxanne was a geologist studying alien rocks when they suddenly fused with her, giving her the ability to turn her body into diamond-hard crystal. Nigh invulnerable in her diamond state, she splits her time between fighting crime, writing papers for the Journal of Extra-Terrestrial Geology, and working out. She's in it for the (female- or nonbinary-identifying) cuties. [From the in-game character profile]
