Che (voiced by Toran Caudell) is a river pirate from the 2017 TV film Hey Arnold!: The Jungle Movie.
Che is introduced as one of "Eduardo"'s (actually Lasombra posing as him) crewmen, whom Olga is instantly smitten with, much to Helga's annoyance. Once Lasombra reveals himself, Che's true colors are revealed, breaking Olga's heart. During the fight sequence, Big Bob, furious at what Che did to Olga, chases him around the encampment and beats him up for breaking Olga’s heart. Che is last seen escaping from the pirate hideout into the jungle.
Despite his betrayal, it would seem that, on some level, Che did care for Olga, as he beat up another guard Olga was "flirting" with, and seemed regretful when he told her to go into the jail cell.
