Ekans is a purple, serpentine Pokémon. Its eyes, underbelly, the thick stripe around its neck, and rattle are yellow. Ekans has three pairs of black lines encircling its body, as well as another line that connects each slitted eye and curves toward its nose. Its large mouth has a round, pink tongue and no visible teeth. While painful, a newborn Ekans's bite is not venomous. This Pokémon grows longer with age. Ekans lives in grassy savannas and plains.
