This slipped past the past week, but has been discussed on the background a while. It doesn’t seem to have leaked into the general lucha libre spanish language discussion, so maybe it still is news.
There was a plan for the Perros del Mal to invade the 02/05 AAA TV taping in Puebla, starting a promotion vs promotion feud. Rey de Reyes would’ve been unchanged, with the Perros making minimal appearances before then, but the story would’ve taken centerstage leading up to TripleMania. I do not know who specifically would’ve appeared, but it seemed more like the core Perros del Mal rudos (Perro Jr., Halloween, Damian, Mr. Aguila) and not necessarily the guys who’ve left AAA on bad terms (Park, Manson) or those loosely aligned with the group (Santo, Demon.)
Instead, for reasons unclear (but mostly guessed to be the Perros backing out), the invasion never happened, and the whole thing was kept quiet until Olimpico made that random comment about it in Box Y Lucha a couple weeks back. The feud can always be brought – next Friday’s DF show seems like a logical place – but there’s been no specific mention that it would.
The Perros could’ve used the relevance that comes from appearing on Televisa, and AAA could’ve used the buzz and change of status quo the new feud would provide. This kind of feud would required a lot of co-operation and teamwork between rival promotions, not something the wrestling business is known for, and probably is a reason why it’s not happening.
Since dropping their participation in this feud, the Perros del Mal have ramped up their live event schedule, so it seems like they’re making a stronger push to make it on their own.
