Cacturne rarely moves during the day to conserve moisture, instead searching for prey or following travelers at night until they become exhausted; it has lived in deserts so long that its blood has effectively turned to sand. Its humanoid green body is covered in cactus spikes, with a rhombus pattern down its front that differs between males and females, and a spiky, hat-like feature atop its head.
Bulbapedia notes Cacturne and its pre-evolution are the only Grass types in the Human-Like Egg Group, and that Cacturne is the only Pokémon from the first three generations never to appear in the anime series or its movies since Pokémon the Series: Ruby and Sapphire, excluding a few species with legal complications.
Cacturne debuted in Sandstorm as a Holo Rare illustrated by Atsuko Nishida, and Team Magma vs Team Aqua followed with a Team Aqua's Cacturne illustrated by K. Utsunomiya. Emerald added a Cacturne ex, and Crystal Guardians gave it a delta species treatment illustrated by Kouki Saitou.
