Making a very short thread with some #tankpeople #lore / #notes / #scribbles / #trivia:
Part 1, the returned phase 2s.
The resistance is looking for alternative food sources, but it seems their bodies' trophic needs won't let them eat anything else quite as efficiently. Wolves and sharks have been suggested.
Part 4 (last part for now), the hunger. The phase 2s can go for a very long time without food, compared to the phase 3s. But eventually they get hungry too. They can't eat and at first don't know why they are hungry, so it slowly drives them mad as the years go by.
A tankhead who doesn't eat turns into a black hole eventually.
Part 2, origins. They aren't human and can't have offspring with humans or each other. Their skin color is basically random - they just picked tones that are similar to the inhabitants of the areas they invaded. It was for blending-in purposes.
