In the Son of Ogre manga series, there's an alternate version of Che Guevara named Jun Gebaru (also known as Edwardo Che Guevara). He was a former pirate who founded his own nation called La Serna. His appearance closely resembles the real-life Guevara in the iconic photograph, and he's one of the three strongest people on Earth alongside Biscuit Oliva and Yujiro Hanma. Jun Gebaru is known for his radical political beliefs, which are anti-capitalist and specifically target the United States (the supposed crime he was imprisoned for is breaking into George W. Bush's house and threatening his family). He enforces strict discipline on himself, making him incredibly powerful. His fighting style involves using only bare hands against all types of weapons, which makes him capable of killing someone with a single hit. He can easily defeat opponents who have guns pointed at their heads or destroy multiple strong and skilled opponents simultaneously.
He goes back to his country after his defeat.
He is first encountered in the Arizona prison, as he has intentionally allowed himself to be captured and imprisoned there in order to battle Biscuit
