Oh, and maybe Khufu and Chay-ara, since they are constantly reincarnated but always find each other and fall in love, are like the avatars/energy source for the Sapphires, who use that love as a power source. So when they were resurrected, it broke their connection to the Zamaron CPB and destroyed the planet? I'm just speculating - I haven't read the issue yet.
They also don't look like the actual bodies of the Hawks. More like a crystallized representation of the ancient Egyptian originals?
