Ekans (アーボ Abo?), is known as the Rattlesnake Pokémon. The name Ekans is the word snake backwards. Ekans' Japanese name, Arbo, is a reversal by morae of the word boa. This reptilian Pokémon has a rattle at the tip of its tail, and is mostly purple while its underbelly, eyes, rattle, and the "bands" on it are yellow.
They swallow whole the eggs of small bird Pokémon, such as Pidgey or Spearow. Ekans are able to detach their jaws to swallow large prey whole, although this makes their bodies heavy. Its highly poisonous fangs make it a hazard in the wild as they slither through the grass and unexpectedly strike. Ekans also shares other characteristics as snakes, such as using its tongue to test the air for the presence of prey, and shedding its skin.
In the anime, the most notable Ekans was owned by Jessie, who had received it for her birthday. For most of the original series, it was her only Pokémon. It was extremely loyal to her and eventually evolved into an Arbok just to make her happy. In Pokémon Mystery Dungeon: Team Go-Getters Out Of The Gate!, Ekans serves as a male character and one of the members of the Team Meanies, in which it was commanded by Gengar to eat all the berries Team Go-Getters collected.
