Every armadillo-kin are born with a soft skin that gradually hardens on the back as they grow. Most newborns walk on four legs, but soon learn to walk on two legs. They can develop very quickly, able to open their eyes and walk perfectly within days, if not hours. A fully developed banded armadillo-kin stand between four feet and seven feet, and weigh around 250 pounds. The giant armadillo-kin can stand from six feet to ten feet, truly giant, and can weigh up to two-thirds of a tonne. Most armadillo-kins' skin color is usually gray or brown, occasionally a little beyond that spectrum, but bright colors are rare, for they need to be able to blend into nature. Their eyes always appear to be squinting, and only the most perspective can see that armadillo-kins' eyes are black, blending the iris and the pupil. Armadillo-kin are cold-blooded reptiles, and bear no hair or fur, and must maintain their body temperature like normal reptiles. However, this is never too much of a problem. If it gets hot, they seek shade and no closeness to others. If it gets cold, they seek the sun. If it gets really cold, they seek other armadillo-kins to huddle up with inside nests underground. The hard skin on armadillo-kins' backs are like armor, and it is hard to put armor over the back (not that they need to), so most just opt to get armor for their front and legs (breastplates and greaves).

If you see an armadillo-kin out walking around with its nose in the air, chances are, it's looking for food. Armadillo-kin in the wild will spend much of its night and occasionally dawns and evening looking for grubs, insects, and tasty plants. They can eat meat, but in the wild, they have not been able to develop the skills to craft and use hunting weapons effectively, so they resort to prey that can't move or can't move fast. Occasionally, they will eat rotting meat like scavengers, though.

Armadillo-kins are also natural diggers. They can, if they wanted to, literally make their own mansion underground. Most of their burrows have multiple entrances and exits, and some hard workers may have burrows that stretch up to one square mile/one and a half kilometers. While there are not many predators who would attack a human-sized armadillo, there are certainly monsters who are more than capable of crushing an armadillo-kin, so when one is sighted, armadillo-kins can move at almost sixty miles per hour/ninety-five kilometers per hour to hide in their burrows. A monster may be able to also enter their nests, but in their own burrow, an armadillo-kin is more than a match against a monster its own size in the cramped environment.

A female armadillo-kin will mate with only one male, while male armadillo-kins may mate with several females during its lifetime. When a female armadillo-kin is pregnant, they are usually pregnant for about eight or nine months, and then give birth, typically in the spring. Mating usually takes place in the summer. armadillo-kins always give birth to identical quadruplets which are all either male or female. All four are from a single egg which has split. These patterns in the mating life of armadillo-kins have not changed from their armadillo cousins, despite the fact that they are humanoid, smarter, and more self-aware. It's the way of nature.
