I have no idea who The Reptiles were behind their masks. They evidently dressed in green and showed up in Arizona in 1967, feuding with Pancho Pico and a variety of other partners. Whether they were two guys passing though or locals donning hoods to do double duty and take an added pay off remains a mystery.
As their name implied, they were sneaky, snakelike villains who did a lot of double teaming and switching off with each other when in trouble. This, however, still didn't get them many wins. They tried, mind you, but like the coyote in the Roadrunner cartoons, things always backfired on them, no matter how thought out.
Eventually Reptile #2 disappeared, either moving onward or removing his hood in secret and continuing on other Arizona cards under a different name. Reptile #1 lingered for a while, teaming with other wretslers, but the impact was not the same. By 1968 he was also out of the area or working there without a mask.
