Humans aren't entirely compatible, but what I would do if I were in a position like Amon's, would be to infest them. Then have them dream nightmares. Every time, I would take the best part of the nightmares, and make them real Zerg. Over time, The Lord of Terror begins to exist from this. Diablo IV. The real world? An interesting side-story. Modern Diablo series anyone? ...Otherwise I'd turn them into copies of 'not-Kerrigan' or something.
