We have a few more images from Zoids Wild and Wild Zero. First, a couple of character concepts:
Fiona's Everyday Wear, and normal!Aldrich Vs. when he is
piloting the Genospino. We also have a
Zoids height chart, which shows some impressive scales. The Kongs are huge, and Jammingas (beside Beast Liger) are tiny. Although not necessarily a concept, the anime twitter also posted a
high-res Fang Tiger image.
