I feel like there's a bit more to unpack here, but it would be more rational, to me at least, if these "lizards" were humans who viewed them as a higher race, as "Dragons", who are the "rightful owners and predators" of mankind.

Dragons are one of the few common myths that are tied into older cultures from around the world. Moreover, dragons are generally revered as powerful and of great worth, particularly in European mythology, which (I believe, I'm not exactly immersed in the world history of dragons) is where the tales of dragons amassing and hoarding wealth originated.

But I can't, without tangible proof, say that any of these elites are literal "lizards". I could very easily believe that this is how they view themselves, however.

(On a side note, I'm getting kind of concerned about the anime, One Piece. It's known to incorporate and adapt a lot of mythos and history from different cultures around the world, but the more that I've seen "behind the veil", the correlations that I see that hint toward the truth that Q seems to be trying to show us.

Of particular note, there is a class of people known as the "Celestial Dragons". They are the "rulers from on high", literally, and the descendants of the founders of the World Government. The Celestial Dragons see themselves as literally above human. They are free to enslave, rape, and kill anyone they so desire, and anyone who dares to look at them the wrong way can be declared as criminal and executed. At one point, I had thought that they were mere caricatures of the elites, but now, if anything, they seem to understate the elites.

It could be that I'm subconsciously relating the term "lizards" to Dragons because of the Celestial Dragons, but I do feel like there is enough separate history to support the conclusion anyway.)
