The original Jaguar presumably became a Cronenberg in Dimension C-137.
Jaguar is a highly skilled rebel fighter who dedicated his life toward toppling the oppressive regime ruling his country (presumably Russia). He was eventually captured by a Russian Agency and imprisoned in their maximum security facility. The agency planned on holding him captive until his natural death, until the invasion of Pickle Rick. The agency director released Jaguar to destroy him. His only motivation was that if he killed Rick, he'd be rewarded by setting his daughter, Katarina free. During his fight with Rick, he realized they had no beef with each other and decided to team up with him, as Rick's mission to see his daughter, Beth, was similar to his mission to get Katarina back. As it turned out, the agency had already killed Katarina, so they flat-out lied to Jaguar, just so he could help them kill Rick. The duo escaped together with Jaguar once asking Rick if he had infinite daughters after hearing some of Rick's background but was told no. Rick then allowed Jaguar to roam free and unimprisoned again.
In the episode's epilogue, Rick and Morty were about to be killed by Concerto, before Jaguar killed Concerto and saved them both. Rick said it was good that he never went to therapy, otherwise he'd have never met Jaguar and he and Morty would have died by the hands of Concerto.
- He is voiced by Danny Trejo, best known for his role as Isador "Machete" Cortez from the Spy Kids film series and the Machete spinoff films.
