Deviant Physiology(Humans vs Everyone Else)

It's kinda interesting that Humans seem to be the odd ones out when it comes to sapience in Tales of Arcadia. Working on some OCs has made me realize nearly every alien species seems to be some sort of Mechanical/Energy-based lifeform instead of Organic/Carbon-based. Even the ones that seem more familiar apparently aren't, as the wiki says(though I don't remember) that Stuart doesn't actually need oxygen, but he doesn't have a breathing apparatus, so the implication is that he just doesn't breathe. The Zerons look like Reptomammals, and might actually be, but Alpha dissolving into orange squares upon death gives me pause classing them as such. Serrators glow blue, so it wasn't an extra pulse from Varvatos' weapon, and it matched the color of his armor almost exactly. Gaia seems to have more soft-bodied creatures, but nobody's autopsy-ing a Goblin(Do their organs liquefy on death or are they just filled with a. Hydraulic fluid?), and the dominant Magical species is made of living stone. "Fleshbags" might be a more accurate insult than originally thought, no-one else is so weird about their physiology.
