For those unfamiliar with Perro's body of work:

I really can't stress enough the magnitude of this death for AAA and lucha in general. This isn't some jobber or midcarder. Perro was a huge star, big draw, he knew the business down to a T. Imagine if, god forbid, Nakamura or Bryan died. Household names. That's what Perro was in Mexico. He was also the top rudo, every star returning or signing with AAA was bound to work a program with Perro at some point. Perro was the centerpiece of booking, the mentality of lucha is that the pillar of booking is having a big top rudo to make flying babyfaces look great. Perro did that throughout his entire career. He was supposed to headline TripleMania with Myzteziz. After that he was supposed to feud with Alberto. The man was in his prime.
Meltzer will say Mistico was responsible for lucha rebirth a decade ago. But Perro was Mistico's arch nemesis, Perro was the villain who made him a loveable superhero and enormous babyface draw.
Luckily for AAA, they're loaded with talent. Mesias (Mil Muertes) just turned rudo 10 days ago, he's a big star as well. Texano and Pentagon will move up the totem pole, which is awesome. Texano was already near the top, but not quite there like Perro was. The fat old fart Villano IV (the Finlay of lucha) could wrestle more regularly. There are Hell Brothers. Maybe Konnan can do a retirement tour. Maybe LA Park and Dr. Wagner can come back and finally have that (expensive) mask match that is 12 years in the making (CMLL, AAA, indies). Short term AAA will be fine because they have a plethora of rudos, but longterm they should really go all in with Texano and Pentagon, because both guys are fantastic in what they do.
