What are the Kotobukiya Zoids?

When the Hasbro released Zoids were available in New Zealand, I got one of everything, opened Liger Zero and Elephander and then had a "how the hell do I store all of these" moment and so sold them all aside from the two I had opened.

I recently saw pics of the Revoltech Blade Liger which looks AWESOME. I think I will have to import that.
