Ok,
I guess that this is the highest form of flattery...
But they are the "Zetas"... and just take a look at the crest - see some things that are similar? Namely the crown and its placement as well as using our flower. Even the stars have 5 points...uhhh
You should also look at the crest in the TV show because it is different - but even more similar to ours - including the Crown at the top, the "guard", the shape, and the way the symbols are situated. They recently switched to this crest for the public part.
