But the question still remains: why were there two Master of Gravity?

I do have another theory though. The first Master of Gravity that we saw was the man in the helmet. Now, what did he do that made us think he was indeed the First Master of Gravity: he flew. Well, what other Elemental Master can fly, without using a visible (fire, lightning, etc.) element: wind! Could it be possible that the man in the helmet was related to Morro, and that he was indeed eaten by the giant Anacondrai Serpent, which would pass his elemental power on to the next generation?

No.

Morro came to Sensei Wu as the new Master of Wind, just after Garmadon had gone to train with Chen. This means that it was still much earlier than the First Serpentine War, and therefore, before the Helmet man was confronted (and possibly eaten) by the Serpent.

Though I'm sticking by my first theory, I decided to bring this train-of-thought up, too, to get the wheels turning.
