This reptilian Pokémon is serpentine. It 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. An Ekans' height is 6'07" and weight is 15.2 lbs.
Ekans are able to detach their jaws to swallow large prey whole, although this makes their bodies heavy. It can also use its tongue to sense danger, and can move quietly through the grass. Ekans was also shown in the second movie to possess some swimming abilities.
Like actual snakes, Ekans will lash out with a bite when frightened by anything it sees as a threat. If one happens to be bitten by a young Ekans, they are lucky. As an Ekans, it does not possess the ability to add venom to its bite until after it evolves into an Arbok, though this last bit of information clashes with Ekans's dungeon phrase.
