Various Assassins, Avengers, Mr Wrestlings and Mongols came through Arizona over the decades. The Mighty Avengers mentioned here worked the Arizona circuit in 1975 and were not around for long, unless of course, they took off their hoods and continued under other names which remains probable.
These Avengers feuded with a wrestler known simply as Apache Joe and a a variety of tag team partners in the border triangle of Arizona, California and Mexico. They were main-eventers in Yuma and across the line in San Luis Rio Colorado.
Again,. not too much else remains on these particular Avengers or their opponent, Apache Joe.
All of those involved with this feud either faded into history or went on under different names.
