Ting-Lu
The third "Treasure of Ruin" legendary is dark/ground, and it's really a huge, sinister looking bowl-shaped "ritual vessel." The dex says that what brought this to life was the "fear poured into it," which kind of implies it was used in cult sacrifice. The vessel alone looks pretty damn cool, a nice blue-tinged bronze sort of color with patches of brown grime, bent horn-like decorations and a big fissure down the middle, but of course the main draw of the Pokemon is its puppet body, this time a four-legged beast made of soil. It's kind of bearlike at first glance, but on closer inspection it's more like an elk, with the urn in place of "antlers." It's pretty threatening, and I like the horizontal stripes of differently colored strata!
