Gastly

Gastly appears as a floating black sphere composed of gaseous matter, enveloped in a voluminous, hazy shroud of purple gas. It features two large, expressive white eyes with small pupils and a wide mouth that often displays a pair of sharp fangs. Its form is indistinct and ethereal, as its body is composed of approximately ninety-five percent gas.

Mischievous, playful, elusive, spooky, prankish.

Wild Pokémon

Gastly is a Pokémon born from poisonous gases that often congregates in eerie locations like graveyards and dilapidated buildings. It uses its gaseous body to slip through tight crevices and can overwhelm larger foes by enveloping them in its toxic shroud. While it is known for its ability to put prey to sleep, it frequently spends its time playing lighthearted but spooky tricks on unsuspecting humans.
