where did cluster lizards come from?
There was a chimpanzee whose favourite food was ice cream. It is unlikely that wild chimpanzees have much access to ice cream. I assume that Cluster Lizards might enjoy or seek out food in artificial circumstances that they never get to enjoy in the wild.
As to the threat parasitic Cluster Lizards might represent to host insects, brain eating and all that, I agree. Parasites
frequently represent a potential threat to human and animal life and health. We evolve defenses and seek treatment to control parasite infestations.
Squish apparently was able to bypass the Gigashadow’s defences. Defences which were proof against Kai. There are a number of possible reasons for this.
If they were parasites, then I imagine they would have fed upon accessible insect tissues, consuming dead skin flakes, gnawing at breaches in the armour, possibly performing hygeine functions. I would also assume some capacity for long periods of dormancy. It’s likely that their metabolic rates, like those of fleas, were tied to their hosts. My guess is that their normal feeding areas on the host insect were fairly benign. In humans, parasites in some areas of the body are fairly tolerable, but when they move internally, then we’ve got trouble.
I think that when the Divine Order was being established, some Cluster Lizards were found, or stragglers may have emerged. They
were adopted by HDS as guardian animals.
In that position, their diet became exclusively human. It may well be that
HDS used human science to try and control
or free the Gigashadow body of Cluster Lizard parasites. After all, who wants to wake up from a 30 year sleep with a bitching case of head lice.
