You weave a good discussion, but I'm largely in disagreement. Here's some points of contention:
- In your theory, theonite is more common than nitrogen.
- If humans are 5% theonite and parasites are 50% theonite, why isn't Double hunting parasites? Why gather krill when you can catch a giant tuna?
- Where do you get the notion that Eliza tasted/consumed Aeon's and Venus's blood? As far as Eliza's story mode goes, Double accuses her of only killing them.
- Gehenna as a factory to extract theonite from Skullgirl victims blood. I agree it a collection of victims' blood, but not for theonite reasons. Forget theonite: for the symbiotic parasite, host blood is super nutritious. You are undervaluing the blood. Eliza skims from blood drives like a vampire with a blood bank because she needs extra blood (beyond the average host and parasite partnership) to stay young and beautiful. Extra blood is her fuel, not trace amounts of theonite.
Perhaps a victim's blood has no theonite in it, but blood could be a medium that is good for containing and preserving theonite. More blood in the pool, the more theonite power to bank. I mean Double has to add something to the blood. It would quickly spoil otherwise.
- Painwheel has two synthetic parasites. An important distinction as Peacock also has two and she does not require Skullgirl blood to survive. But you are correct the Skullgirl blood (how did Brain Drain acquire this?!) does grant Painwheel super-healing qualities.
- The varied races of humans, ferals, dagonians, gigans, and so on wishing for environmentally-influenced change reeks of Lamarckism (a bogus evolutionary theory based on a parent's modified trait passing onto a child. For example, a giraffe gets its long neck from each generation stretching its neck to reach high leaves). Normal evolution without theonite over millions of years is sufficient cause for the variety.
Saying the Life Gem is pure theonite is intriguing, but where is this cited? I don't see it in the canon info thread.
