Undead Themed Powered Armor

I'm looking for something that can be described as what I put in the title. An undead themed powered armor. I'm gonna be changing the stats of it slightly to be what I need, but essentially I'm making an undead enemy in powered armor, using the Necrovite graft. Funny thing, I'm calling the thing's species "Grafted" too. But I want a suit of powered armor for a BIG creature to fit the theme. Worst case scenario, I can change a Jarlslayer cosmetically, but I'd rather not.
