Some basic side profile character concept, just so i can use it in the future maybe
Considering he's supposed to be another merceneary it's only fitting he got some military mods:
A LVL3 face shield to stop low calibre firearms from fracturing his face
A "backpack" serving as more of a "Extension" slot, hooked up with more power cells for longer missions without stopping
On top of that a "limb module" added to the backpack so you can be a bit more handy in a fight or out of it
The entire backpack system connected to the android with power+signal cable foiled and wrapped in a steel mesh to add resistance and combat magnetic interference, plugged directly into the protogen's head for ease of access
And additional chest steel plates to better protect those internals
Reinforced tail with a pneumatic spike at the tip for melee combat or to serve as an anchor (during rough-sea ship combat, mitigating recoil/pushback)

Sorry if it's a bit hard to read the image, i don't have a working scanner

Do you still get hunted for drawing protogens with a bit more spice ? I sure hope not
