UPDATE: I colored them.
I was sketching some masked characters and these two is what I liked the most.
Enter VoID and CaOS. Two heavy built tanks that was decommissioned after the war. Now, they're looking for something to get themselves occupied. VoID is somehow lacking knowledge of most of the stuff, or perhaps, he is just too intelligent to be understood by normal humans. CaOS also called Bull Moose by his former squad, tends to be hot headed and aggressive, but somehow a bit of a narcissist.
Who would you give a hug?
