Vordt. However, not nevessarily human armor. It could, for instance, be a horse made out of horse armor.

Well, without knowing anything else about the story, my first approach would be to consider armour's purpose. I.e. defence and disguise. And then weave that into the design of the monster.

Hm.. Thinking about it that way it’s hard for me to visualize anything but human armor.

The thing about monsters is that you have two possible avenues for writing them. 1. It's an animal that naturally exists in either A) the current setting or B) a different setting but it's been transported in some way to the current setting. 2. It's a magical artifact or technologically constructed weapon. In the case of Avenue 1, you need to consider it from an evolutionary standpoint, i.e. how does it survive, hunt, sleep, mate, eat, kill, etc. So no reptiles in the Arctic, for example. Because how are they keeping warm? In the case of Avenue 2, you need to consider it from the creator's perspective. Why would someone create this being? How do they control it? If they can't control it, why would they make it? That kind of thing. This kind of thought process/mindmapping is the best way to create a fictional creature. And can help you develop the setting, chatacters and plot more too. From there, take the Nintendo approach to aesthetic: form follows function. Which is the same way real animals evolve and, often, how real technology is designed too.

Well, it’s definitely avenue 2, and their purpose is to kill. Each one is pretty specialized in how it kills, though.

See, armour doesn't come across as a method of killing to me. It's a defensive thing. I guess you could use the weight as an offensive aspect? Or combine it with medieval style weapons.

I guess I never mentioned that they’re combined with weapons did I? They are. Some of them wield weapons separately, while others have it grafted into the armor itself. For example, there was a giant centipede thing, and it tried to kill the hero by running them over, and impaling them with its hundreds of bladed feet.

Ahh right. So are these like golems created by a superior antagonist?
