Eggward is a robot created with super AI. As he started to develop consciousness, his creator injected cocks DNA in all his body parts in order to make him looks like other cocks. But he died before he could finished it, leaving Eggward unfinished with his beak still in robot form.
Cocks call him Scissorbeak and bullied him all the time. He decided to travel and live alone in Albuquerque, a dead city that had just been wiped out by a virus outbreak back then.
That's when he met Saul, a baby cock that survive the outbreak and he has been taking care of him until now, and both live a happy life away from crowds.
