Choro is a Leprictidium, a rat-like forest dweller. He stands shorter than Gon, with a distinctive high-heeled leg enabling rapid movement, prominent whiskers, and an elongated tail. His behavior is marked by impulsiveness, especially when darting away after stealing food. Choro occasionally leverages his speed advantage cleverly, tricking other animals into wagers that benefit him. His primary focus involves pilfering food from fellow forest inhabitants, an act that frequently demands swift evasion from rightful owners. This establishes adversarial relationships within his ecosystem.
