Octagon is a long-time star of Mexican wrestling. Debuting in that gimmick in 1989, he became a huge star in a Mexico in love with martial arts. He rose to fame quickly, scoring movies and endorsements and main event spots. But AAA realized they needed an arch-nemesis for their character, so Pentagon was created.
Pentagon was the dark double to Octagon. Multiple talents would wrestle under the mask, almost always against Octagon or his allies. In this classic encounter circa 1994, Octagon teams with the still very young Rey Mysterio while Pentagon recruits an American (or is it Russian?) ally in KGB, actually American MMA/wrestling hybrid star Tom Howard, who would go on to co-found UPW and as trainer, start off the careers of John Cena and Samoa Joe. It's an interesting bout that shows off a lot of what is great about Mexican tag team wrestling.
