Ekans

Ekans is a Poison-type Pokémon introduced in Generation I, famously known as the "Snake Pokémon." Its name is "snake" spelled backward, a clever nod to its serpentine form. Ekans evolves into Arbok starting at level 22. Native to Kanto, Ekans is often found in grassy areas, forests, and caves, where it preys on bird Pokémon eggs. Its diet primarily consists of eggs, which it swallows whole. Ekans is known for its ability to constrict its prey and inject venom. In the anime, Ekans is a prominent Pokémon, most notably as one of Jessie's original Pokémon in Team Rocket, showcasing its loyalty and cunning nature. Its appearance in the games and anime has cemented its place as an iconic early-game Poison-type, often encountered early in a trainer's journey, and representing one of the more common and recognizable snake species in the Pokémon world. Its design is simple yet effective, emphasizing its reptilian characteristics and its potential for danger.
