Theory for 2 Godzilla's in The New Movie

So, what I have to discuss since I'm a new member to the forum, is the theory of 2 godzilla's in the new movie. Now let's get started

So, I dont have any hard evidence, again this is just a theory.Take a look at the text from the giant size JAKKS pacific godzilla, the first thing that is said is "Possibly the last of an ancient species of giant amphibians." That sentence right there may suggest a hint, thus put some emphasis on that it said possibly, not THE last, but POSSIBLY.

Taking a look back to one of the first posters to pop up on the internet, is the HALO jump poster looking down from the sky at a roaring fire ablazed in San Francisco, and on the left you see godzilla's spines, now for a minute, analize the pattern you see on this "godzilla". Notice in the main trailer that we can get a decent look at the spine pattern, and in the others as well. The problem and possible spoiler i see it that the San Francisco spines DO NOT MATCH!!!!!!

And why i also strongly support this theory is that Gareth Edwards has told everyone that has seen that seen to swear on secrecy. If its just another MUTO, ill be kinda made because of this big secret being something we already know about. Edwards also has mentioned that that climax point literally twists the idea of godzilla and gives him a whole new element, when you piece things together, at least for me, it can be pretty clear that this is probably whats going to happen.

And also, how could godzilla survive on his own, after all he is a species in this movie, there's a skeleton of another gojira, so why woudlnt there be another? It in a way makes perfect sense, tell me your thoughts below, thanks, Brandon
