After US: the enemy, an alien species

Enemy: an alien species
When I started to create the enemy there are a few principles I tried to establish before I start.
1. They should neither simply bad nor evil, the reason they become enemy is that they have conflicts of interest with our side.
2. Their culture and technology goes a different direction compare with us.
3. The body structure is different with life on earth.
Then I got some sketches of them.

Left two has flexible limbs, and right two has heavy armor.
I felt like I found the right direction for the species, Them I made more thumbnails of it to try to explore different body structure and functions. For the consideration of rigging and animation I was still trying to keep them as human like structure.

I chose the second one from right to do some some further exploration.

This one has a few unique features.
1. Flexible limbs
2. Two flexible auxilliary limbs, Start from armpit expend to waist, could be used to carry materials or weapons or hold a shield.
3. Apathetic appearance
4. The alien is actually in the chest of the body, the body just its exoskeleton like a battle suit.


The background of this suit is this alien species travel a new system, then they will use the structure of the strongest species in the system to build their battle suit, that's why the suit has human outline.
