I just remembered this movie and I really want to watch it again. But then my messed up brain came up with a Claytro AU for this.
Sorry, Jestro; I made you the cute zombie boy. He does not completely remember his name though. He just knows that it starts with J. He usually communicates through grunts and groans; only saying a few words at a time in a rather croaky and rough voice. He knows he has to eat human flesh, but he gets conflicted about it. During a walk through the outskirts of the city, the zombie hord he usually walks with attack a group of human scavengers. J manages to devour one(not one of the Knights don't worry) and take his brain for food. But one of the humans gets injured and separated from the others. J rescues him from the other zombies and takes him back to his makeshift home; telling him he is keeping him safe.
Here's Clay; an elite survivalist from the safe haven of Knighton City that gets separated from his team during a zombie ambush. To be found and rescued by J of course. While he appears brave and serious to his teammates, he does get scared at points but he tries to keep his cool in most situations. During his time with Jestro, he is skeptical of the zombie at first. But he opens up and bonds with him when he begins to show human traits and behaviour. Even signs of life.
When you're a zombie and you try to give your living crush dead flowers(with your odd and uneven arm) as a gift.
When you try to talk but everything you say just comes out as a dead groan. With occasional drool.
Full body pic of zombie J. He wears mixed matched shoes. Even as he zombie, he sometimes goes looking for clothes in the ruins of the abandoned city.
"J loved listening to Clay when he talked about things. He did not really know why. Just hearing it made him feel right; like he could just forget that he was basically dead. "
