Nyasu, identified as Meowth in English, is a Scratch Cat Pokémon appearing as a feline creature with cream-colored fur, brown paw and tail tips, and a distinctive gold coin embedded in its forehead. This species roams nocturnally, displaying a documented attraction to shiny objects that often leads it to wander urban environments at night, collecting loose change or glittering items. Its eyes visibly gleam upon such encounters, and the forehead coin emits a bright glow. Nyasu possesses retractable claws enabling silent movement and demonstrates the unique ability to generate coins via its signature Pay Day move. While capable of bipedal walking, standard locomotion occurs on all fours. Temperamentally, it exhibits a playful but unpredictable nature, with recorded instances of human-like intelligence, including self-taught speech in at least one individual. Within the "Pikachu to Eevee Friends" narrative, Nyasu deliberately stirs mischief at the Eevee House—a gathering place for multiple Pokémon—instigating widespread chaos during a summer event. The character's actions align with established species traits of curiosity and occasional troublemaking.
