ekans

Ekans is a Poison type Pokemon from Kanto, a purple snake with a yellow band around its body, a rattle like tip on its tail and a wide, toothy grin. Sneaky and quiet, it slithers through grass to hunt and later evolves into Arbok. It is famous as a Team Rocket partner in the anime, and fans draw it as a mischievous no humans critter coiled and ready to strike.
