Post ideas for new enemies! Here's some of mine:

Dwarven Top / Spinner
It would be a Dwemer sphere with a ring around it. On the ring would be legs like a spider. The sphere would spin to let it move and the legs on the ring would extend outward to slice those who came near. It would only stop the blade legs to attack with its blade arms, making it vulnerable to melee attack.

Giant Dwemer Spider boss
It has a centurion torso as it's upper body. It would be titanic, as big as the spider queen in Okami. You would run around it on walkways and bridges suspended above lava while it fired explosive crossbow bolts and swung at you with it's arm-blade, destroying some of the bridges in the process. You would kill it by killing dwarven spiders, spheres, ballistas, and centurions that it sent at you and firing their cores at it from a dwemer crossbow, mounted in the area.

For scale:

In addition to these enemies I would like to see random werewolves and frost giants with increased frequency in Skyrim proper.
In addition to this I'd love a reduction in the rate of vampire appearances, especially in cities, they be killing my blacksmith at Whiterun's gates while I'm messing around at Dragonsreach's gates. They're seriously everywhere...
I'd also like to see dwarven ballistas to spawn in vanilla dwemer ruins for variety's sake.

Now, let me hear all of your ideas!
