Poncho serves as a secondary antagonist within the Gangreen Gang in the anime adaptation. He is the gang's smallest member and utilizes super speed as his primary ability. In the English dub, he is dubbed "Weevil." The Gangreen Gang regularly commits petty crimes and causes disruption throughout the series, though Poncho himself receives little individual narrative focus or distinct background. His documented involvement across official media, including seasons, films, OVAs, and spin-offs, lacks significant character development, backstory, or an expanded role. Poncho's actions remain confined to group activities with the Gangreen Gang, without standalone story arcs or personal evolution.
