bio: Mortis was already dead before they even lived. this caused parts of his body to decay rapidly(mostly his legs), he replaced these decaying body parts with machinery so that they could do simple things like walking. They stand at a staggering 8 feet tall and likes to loom over other people and watch what they are doing. As big as they look they are sometimes hard to spot, able to climb into very hard to reach spots and hang off of ceilings. Some people call him "the watching zombie" due to his crossed out eyes.

I mean, it is a 8 feet tall living corpse. who wouldn't be scared a bit?
