For reasons related to the background of the setting, Arvarans are only Mammals and some marsupials. No reptiles, no insects, or the like. And no mythological creatures either, as that doesn't make sense from a lore point of view.
A bit of a shame. When it comes to humanoid creatures, snake people are my top choice (and to a lesser extent, other kinds of reptiles) for thematic reasons as well as the interpretations by the aforementioned authors. I have a better idea on how to write snake characters then other kinds of animals.
I guess my second choice would be bears. Would that work with the lore?

It is an acronym, and in true anime tradition, probably a highly redundant one. There's some in-game disagreement about exactly what it stands for - it kind of depends who you ask and what their background is, but the commonly agreed one is:
General purpose
Exoskeleton
Augmented
Robot
Now I am wondering why it is named that way unless it is something about them being the 'gear or cog in the machine that is the military'.

While I'm waiting on some more info, guess I'll start figuring out characters and whatnot.
