Elekid

Elekid is a yellow, round-bodied Pokémon with black stripes. Elekid's arms are bulky in proportion to its body, and it has three claws instead of fingers. It has two stripes on its arms, which wrap all the way around. There are two horns on top of its head which resemble the prongs of a plug, complete with holes in their sides. These horns glow bluish-white when Elekid is fully charged. Elekid has a black lightning bolt marking on its chest. Two rows of stripes are near the marking, with the pattern continuing around its lower back. Its legs are black, and its feet are rounded and toeless.

Elekid tends to become restless and full-on rowdy when it hears the sound of thunderstorm coming, and likes to play out in the middle of thunderstorms. It can generate electricity by rotating its arms, but it tires easily and can only charge a small amount. Elekid cannot store the electricity it generates, so it prefers to break into the houses of humans in order to consume electricity from their electrical outlets. It lives in the grasslands.
